Server Quality Checklist

67%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v0.2.2

  • Disambiguation5/5

    Each tool has a clearly distinct purpose: server status, agent run, code review, session management, web search, background run polling, termination, and CLI help. No two tools overlap in functionality; descriptions are explicit about roles and restrictions.

    Naming Consistency3/5

    Tool names are all lowercase single words without underscores or camelCase, but they lack a predictable pattern like verb_noun. Some are verbs (check, stop), some nouns (sessions, status), and 'websearch' is a compound. The naming is readable but not strictly consistent.

    Tool Count5/5

    With 8 tools, the server covers its core domain—running Grok Build, reviewing diffs, searching the web, managing sessions, and monitoring background tasks—without excess. Each tool feels necessary and justified for the Grok Build integration.

    Completeness4/5

    The tool surface covers all major workflows: running an agent, reviewing code, searching, session retrieval, and background task management. Minor gaps exist (e.g., no dedicated tool to list models or configure settings), but the core functionality is well-represented.

  • Average 4.6/5 across 8 of 8 tools scored.

To manually sync the server, click the "Sync Server" button in the MCP server admin interface.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds value by detailing exactly what is reported (version, binary, permission ceiling, CLI readiness, run defaults), giving the agent concrete expectations about the output. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence conveys all necessary information without filler. It is front-loaded with the purpose and lists specific outputs. Slightly dense but efficient; no unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given zero parameters and no output schema, the description fully captures what the tool does and what it returns. It is self-contained: an agent reading it knows exactly when to call it and what information to expect.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    There are no parameters (0 params), and schema coverage is trivially 100%. Per calibration, baseline is 4. The description has no need to explain parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Report') and resource ('grok-build-mcp-server status'), clearly stating it outputs version, binary, permission ceiling, CLI readiness, and run defaults. It distinguishes from siblings by noting it is the first diagnostic step when a grok tool misbehaves, separating it from tools like 'grok', 'status', and 'help'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly states 'Call this first when a grok tool behaves unexpectedly,' providing a clear when-to-use directive. It does not mention exclusions or alternatives, but the context is sufficient for an agent to decide to invoke it for troubleshooting.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description discloses that the run is headless and returns metadata, which are behavioral traits not covered by annotations (no destructiveHint, no readOnlyHint specifics). It adds context about permission capping and rejection. The annotations already indicate a non-read-only, non-idempotent operation, and the description expands on that by detailing the permission model and return structure.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise—only three sentences—and front-loaded with the core action. Every sentence adds meaningful information: what it does, what it returns, and how permissions work. No fluff or repetition of schema details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given that there is no output schema, the description does cover the key output ('model text plus session, usage, and cost metadata'). The tool is complex with 20 parameters, but the schema itself provides detailed descriptions for each. The description could be slightly more complete by mentioning that the tool runs in headless mode only (which is already clear), but overall it is adequate for an agent to invoke it correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, meaning every parameter is described in the schema. The description adds value by explaining the overall return structure and permission behavior, but does not add unique semantic context for individual parameters beyond what the schema already provides. A score of 4 is justified because the schema already does the heavy lifting with detailed descriptions and examples (e.g., deny/allow rules in `ToolPrefix(glob)` form).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Run a headless Grok Build agent'), the command used (`grok -p`), and the output ('model text plus session, usage, and cost metadata'). It also distinguishes from sibling tools by mentioning headless execution and returning metadata, which is distinct from tools like `status` or `stop` that deal with run management.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description mentions permission ceiling ('GROK_MCP_PERMISSION_CEILING') and behavior for exceeded requests ('rejected rather than silently downgraded'), which helps agents understand constraints. However, it does not provide explicit guidance on when to use this tool versus siblings like `review` or `websearch`, or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already convey idempotent and destructive hints. The description adds critical behavioral context beyond annotations: that it terminates both the worker and the spawned grok process, that stopping a finished run is harmless, and that a cancelled run may still yield a session id. This latter point is a non-obvious side effect that an agent must know, which is valuable transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two focused sentences: the first states what the tool does and its coverage, the second clarifies edge cases. No filler or redundant information. Every sentence adds distinct value, making it highly efficient for an agent to parse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the low complexity (single parameter, no output schema, no output objects), the description fully covers the tool's purpose, parameter, side effects, and edge cases. The schema and annotations are leveraged well, leaving no obvious gaps for an agent to misunderstand.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema documents the one parameter (runId) with a format constraint and description. Since schema description coverage is 100%, the baseline is 3. The description adds value by explicitly linking the parameter to the return values of background calls for grok/review/websearch, reinforcing its provenance and acceptable values, which warrants an above-baseline score.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Terminate') and clearly identifies the resources it acts on: a background run, the worker, and the spawned grok process. It also distinguishes from siblings by naming the three run types it applies to (grok, review, websearch), making its scope precise and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides clear usage guidance by listing the types of runs it applies to (grok, review, websearch). It also explains a borderline case ('stopping an already-finished run is not an error'), which helps the agent decide when to use this tool without hesitation. However, it does not explicitly state when not to use it or name alternatives among siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already mark readOnlyHint=true and destructiveHint=false, so the description reinforces this by explaining why there's no write capability ("a review that edits the code it is reviewing is never wanted") and how it ignores permission ceilings. This adds valuable context beyond the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise (4 sentences), efficient, and front-loaded with the core purpose. Every sentence contributes unique value: targets, auto-detection, read-only guarantee, and structured mode option.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 10 parameters, 100% schema coverage, no output schema, and annotations present, the description covers key behavioral aspects (read-only, auto-detection, mutual exclusivity) and provides usage patterns. It doesn't explain return values, but since there's no output schema, the tool likely streams output. A slight gap is not detailing the polling flow for background runs, but overall comprehensive.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description adds cross-parameter relationships (mutual exclusivity), auto-detection logic, and the purpose of structured mode, which goes beyond individual parameter schemas.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it reviews a git diff using Grok Build. It specifies the three targets (uncommitted, base, commit) and auto-detection behavior, distinguishing it from sibling tools like check, grok, or sessions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides explicit guidance on when to use each target mode (working tree, merge-base diff, single commit) and the auto-detection fallback. It also clearly states that review is read-only and lacks permission/write arguments, which helps the agent avoid misuse.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and idempotentHint=true. The description adds significant behavioral context: the local-only nature, case-insensitive substring matching, parameter interactions (id ignores others, limit ignored when id set), and the ability to resume sessions from any directory using the returned id. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise at about 4 sentences, front-loading the main purpose. It includes some repetition of the local-only constraint (appears in both the main description and the query parameter description), but overall it is well-structured and not overly verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 4 parameters, no output schema, and good annotations, the description is largely complete. It explains the local store, parameter behavior, and usage of returned ids. It does not describe the output format, but this is mildly acceptable given the lack of output schema. Overall, it provides sufficient context for correct invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters5/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, but the description adds substantial meaning beyond the schema: it explains the role of each parameter in a usage context, specifies that id ignores other parameters, and clarifies that limit is ignored when id is set. This provides a semantic understanding that the schema alone does not convey.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (List and search), resource (Grok Build sessions), and scope (local store at $GROK_HOME/sessions). It explicitly distinguishes from remote search by noting it does not consult any remote index, which helps differentiate it from sibling tools like 'grok sessions search'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides explicit guidance on when to use each parameter (id for single session, query for substring search, cwd for directory filtering, limit for max rows). It also states that search is local-only and not for remote queries. However, no explicit contrast with sibling tools like 'check' or 'review' is given, though the context is clear enough.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows this is a safe, non-mutating operation. The description adds value by revealing the implementation detail that it runs `grok --help` and captures stdout, which is behavioral context beyond what annotations provide. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, zero waste. The first sentence states the purpose, the second provides implementation details. Both are essential for the agent to understand the tool's behavior. Excellent front-loading.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has no parameters, no output schema, and very simple behavior. The description fully captures what the tool does, how it works (runs a command), and what it returns (stdout). For a help tool, this is completely adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% (no parameters exist). The description mentions no arguments, which is consistent. With 0 parameters, the baseline is 4, and the description adds no further info about parameters because none are needed.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool runs `grok --help` and returns its stdout, specifying the exact verb ('show'), resource ('Grok CLI help text'), and execution method. This distinguishes it entirely from sibling tools like `check` or `websearch`.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description clearly explains when to use this tool (to show the grok CLI help text), but does not provide explicit guidance on when not to use it or mention alternatives among siblings. For a tool with 0 parameters and a narrow, well-defined purpose, this is adequate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Beyond annotations (readOnly, idempotent, non-destructive), the description adds critical behavioral details: finished runs replay the original result verbatim, abandoned runs are reported as such, and a timed-out wait is not an error. This fully informs the agent of runtime behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three sentences, each earning its place: first sentence states purpose, second explains result semantics, third gives parameter usage patterns. No redundancy, front-loaded with the primary action. Extremely efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 4 optional parameters, no output schema, and good annotations, the description covers all necessary aspects: three operational modes, parameter interactions, special cases (abandoned, timed-out wait), and the exact replay behavior. An agent has everything needed to use the tool correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so each parameter is already documented. The description enhances this by explaining how parameters interact (omitting runId triggers list mode, waitMs is ignored in list mode) and provides defaults (8192 bytes for tail, 20 limit). This integration-level meaning adds value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description opens with a specific verb ('Poll') and resource ('background run') and explicitly lists the types of runs (grok, review, websearch). It distinguishes the tool from siblings like 'check', 'stop', and the run-initiating tools by making the polling/list usage obvious.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explains when to use each parameter combination (runId for inspection, waitMs for blocking, omit runId for listing). While it gives clear context and distinguishes the three modes, it does not explicitly state when not to use this tool or name alternative tools for other scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description goes beyond annotations by detailing runtime behavior: it always runs with `--permission-mode plan --sandbox read-only` regardless of GROK_MCP_PERMISSION_CEILING, lacks permission/write/yolo arguments, and never passes `--disable-web-search`. This adds significant context not covered by the readOnlyHint and openWorldHint annotations. No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Four sentences, zero filler. Each sentence adds unique information: research purpose, prompt-only parameters, fixed read-only behavior, and special flag avoidance. Front-loaded with the primary verb. No unnecessary words or redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 9 parameters (with 100% schema coverage), rich annotations (readOnlyHint, openWorldHint), and no output schema, the description is complete enough. It covers the tool's safety profile, parameter effects, and constraints without needing to detail outputs. No gaps that would confuse an agent selecting or invoking this tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the baseline is 3. However, the description adds value by clarifying that `numResults` and `searchDepth` only shape the prompt and have no CLI flags, and that `background` runs detached. It also explains `query` is the body of a web-search-shaped prompt. Not quite a 5 because it could weave in more hints about how `effort` and `model` interact with the CLI rejection logic, but still above baseline.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it researches a question using web search, with a specific verb ('research') and resource ('Grok Build's web search'). It distinguishes itself from siblings by explicitly noting it never needs to write, which sets it apart from write-oriented tools like grok or review.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides explicit usage guidance: it always runs read-only with a fixed permission mode, never passes `--disable-web-search`, and explains that `numResults` and `searchDepth` only shape the prompt. It also indirectly suggests when not to use this tool (if write access or a different permission mode is needed), complementing the sibling context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
