Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.2.21
Disambiguation4/5
Tools are mostly distinct with clear purposes. Some overlap exists among version-checking tools and search tools, but descriptions effectively differentiate them. A few compound tools also help reduce ambiguity.
Naming Consistency5/5
All tools follow a consistent 'midnight-verb-noun' pattern in snake_case. Verbs are descriptive and uniform, with only minor deviations like 'auto-update' using a dash within a compound word.
Tool Count3/5
With 30 tools, the server covers a wide range of functionality for Midnight development. While comprehensive, the count is on the higher side and could potentially be streamlined by merging some overlapping tools without losing clarity.
Completeness4/5
The tool surface covers the full development cycle: analysis, generation, compilation, security review, documentation, version management, and search. Minor gaps exist (e.g., no deployment or testing tools), but these are within the intended scope of an MCP assistant.
Average 4.3/5 across 30 of 30 tools scored. Lowest: 3.2/5.

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

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
ReadOnlyHint already signals no side effects. Description adds 'across Midnight repositories' context but no additional behavioral traits (e.g., rate limits, pagination). No contradiction.
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?
Two sentences, front-loaded with the action. The second sentence adds minor utility but does not waste space.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a simple read tool with annotations. Lacks details on return format or ordering, but no output schema exists to compensate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with clear parameter descriptions. Description does not add extra meaning beyond schema. Baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description states 'Retrieve recent changes and commits across Midnight repositories' with a clear verb and resource. It distinguishes from siblings like midnight-get-file or midnight-get-latest-syntax, though no explicit differentiation is provided.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Says 'Useful for staying up-to-date' but provides no when-to-use, when-not-to-use, or alternatives. Given many sibling tools, agent lacks guidance on selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, covering safety and scope. The description adds content details but no additional behavioral traits like potential network calls or response size. It does not contradict 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 a single, concise sentence that front-loads the action and resource. Every word contributes value without redundancy or fluff.
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?
The description adequately covers tool purpose and output content. However, given no output schema and the complexity of migration guides, it could mention format, size expectations, or prerequisites for completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage for parameters is 100%, with each parameter already described. The tool description does not add further meaning beyond the schema, so baseline 3 is appropriate.
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 retrieves a migration guide for version upgrades, specifying content (breaking changes, deprecations, steps). It effectively distinguishes from sibling tools like midnight-check-breaking-changes which only check for changes, not provide a full guide.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide any guidance on when to use this tool versus alternatives. With many siblings performing related but different checks, agents would benefit from explicit usage context or exclusions.
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 declare readOnlyHint=true and idempotentHint=true. The description adds significant behavioral context: it performs static analysis only, catches common patterns but not semantic errors, and lists specific checks and limitations. No contradictions 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured, starting with the main purpose, then critical checks, additional checks, usage guidance, and a note. It is front-loaded and every sentence adds value, though it could be slightly more concise.
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 output schema exists, the description does not need to explain return values. It covers the tool's purpose, checks, limitations, and usage context. Error behavior is not addressed, but overall it is comprehensive for a static analysis tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with both parameters described. The description does not add new meaning beyond the schema; it repeats the OR relationship. With high schema coverage, baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool extracts and analyzes Compact contract structure with specific checks listed. It uses a specific verb and resource, but there is a sibling 'midnight-analyze-contract' that could overlap, and the description does not explicitly differentiate from it.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description advises using the tool before generating contracts to catch syntax errors, providing when-to-use guidance. However, it does not mention when not to use or explicitly compare to alternative tools, such as 'midnight-analyze-contract' or compile tools.
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 declare readOnlyHint, idempotentHint, and openWorldHint. The description adds significant context: it uses the client's LLM, requires sampling capability, and describes the output (summary, issues, fixes, improved code). No contradictions 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a title, purpose statement, bullet lists, and a requirement note. It is front-loaded with the core purpose. While not overly verbose, it includes some redundancy (e.g., 'AI-Powered' and 'Uses the client's LLM').
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 presence of output schema (implied by context signals) and annotations covering safety and idempotency, the description is thorough: it explains the tool's purpose, checks, output structure, and a key prerequisite. No gaps are evident.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a clear description for the single parameter 'code'. The tool description does not add further information about the parameter beyond mentioning it uses the client's LLM, which is implicit. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs security review and analysis of Compact smart contracts, listing specific checks (security, privacy, logic, best practices, performance). However, it does not explicitly differentiate from the sibling 'midnight-analyze-contract', which may have overlapping functionality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description specifies a prerequisite (client with sampling capability) and lists the checks performed, giving some context for when to use. However, it does not provide explicit guidance on when not to use or alternatives among sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the description does not need to restate these. The description adds context about ensuring recommendations match the user's version, which is helpful but does not disclose potential failure modes, caching, or version resolution details. Minimal addition beyond 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?
Three sentences: purpose, critical note, and preference directive. Every sentence adds distinct value, and the purpose is front-loaded. No wasted words or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the core purpose and usage context but lacks details about the return format, error behavior (e.g., version not found), and edge cases. Given no output schema, additional output description would improve completeness. Annotations partially compensate for safety context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema covers all three parameters with descriptions (100% coverage). The tool description does not add any parameter-specific meaning beyond the schema. According to guidelines, baseline is 3 for high coverage, and no extra value is provided.
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 gets the exact content of a file at a specific version, and explicitly distinguishes it from the sibling 'midnight-get-file' by emphasizing version accuracy. The verb 'get' and resource 'file at a version' are specific, and the critical note reinforces the unique value.
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 explicitly says to prefer this over 'get-file' when version accuracy matters, providing clear guidance on when to use this tool. It does not explicitly state when not to use it, but the preference directive implies alternatives. Could be more comprehensive with exclusion criteria.
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 declare readOnlyHint and idempotentHint, indicating safe repeated calls. The description adds behavioral context by specifying what the health check returns (server status, API connectivity, resource availability). 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

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?
Well-structured with bullet points and formatting, but slightly verbose (emoji, heavy bold). Could be trimmed without losing information. Front-loaded with key purpose.
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 output schema exists (not shown but signaled), description doesn't need to cover return values. It covers input requirements, format options, and output contents. Missing error handling or rate limits, but acceptable for this tool type.
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?

Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states requirement for client sampling capability (e.g., Claude Desktop), guiding when to use. However, it doesn't contrast with alternatives or state when not to use, so slight deduction.
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 indicate read-only and idempotent behavior. The description adds the progressive disclosure pattern and that it provides 'detailed tool information', enhancing transparency beyond 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?
Two short, front-loaded sentences with an emoji. Every sentence serves a purpose, and the structure is 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?
Given the tool's simplicity (2 parameters, enum, output schema present), the description fully covers usage context, including the progressive disclosure pattern with sibling tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema provides full parameter descriptions (100% coverage). The description adds no new parameter semantics beyond the schema's details, meriting the baseline score.

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 well-structured with clear sections (REQUIREMENTS FORMAT, CONTRACT TYPES, EXAMPLE USAGE, ⚠️ REQUIRES). Every sentence is informative and earns its place, though slightly lengthy.
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 tool's complexity and presence of output schema, the description covers requirements format, contract types, example, and prerequisites. It is sufficiently complete for an AI agent to understand and invoke 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?
With 100% schema coverage, baseline is 3. The description adds value by explaining contract types, requirements format, and providing an example, which aids in understanding parameter usage 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 clearly states 'Generates Compact smart contracts from natural language requirements.' It uses a specific verb ('Generates') and resource ('Compact smart contracts'), and distinguishes from sibling tools like midnight-analyze-contract or midnight-review-contract by focusing on generation.
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?
It provides clear context on when to use (natural language requirements), but lacks explicit guidance on when not to use or alternatives. It does mention required client capability and gives example usage, but does not compare to other sibling tools.
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?
Goes well beyond annotations by detailing fallback to static analysis, explaining response field validationType, and providing time estimates for compilation modes. Aligns with readOnlyHint and idempotentHint, 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?
Well-structured with sections, bullet points, and emojis. Each sentence provides distinct value. Slightly verbose but not wasteful; could be tightened slightly.
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?
Covers purpose, usage guidance, parameter behavior, fallback, and response interpretation. With output schema present, return values don't need explanation. Complete for a compilation tool with moderate complexity.
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 baseline 3. Description adds practical context: time estimates for skipZk vs fullCompile, default behavior, and fallback implications for parameters. Adds value beyond 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?
Clearly states it compiles Compact code using a hosted compiler service, distinguishing itself from static analysis tools like midnight-analyze-contract. The emphasis on 'REAL COMPILATION' and 'returns real compiler errors' makes its purpose explicit.
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?
Provides clear when to use (after generating/modifying code, for validation), when to use each option (skipZk for quick validation, fullCompile for final checks), and explains fallback behavior when service is unavailable. Implicitly contrasts with static analysis tools.
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 provide readOnlyHint=true and idempotentHint=true, indicating safe and idempotent behavior. The description adds context by stating it 'matches your intent against known patterns' and returns recommendations with confidence levels. 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?
The description is concise and front-loaded with the key purpose. It uses emojis for clarity, presents examples in a structured list, and includes a separate usage guidance section. Every sentence adds value without 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 the tool's simplicity (one parameter, read-only, idempotent), the description is complete. It explains the tool's function, usage patterns, and expected output (recommendations with confidence levels). An output schema exists, so return values are covered.
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% with one parameter 'intent' described as 'What you want to accomplish (natural language description)'. The description goes beyond by providing examples of phrasing intents, which adds practical semantic guidance for the user.
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's purpose: natural language intent matching to recommend tools. It uses a specific verb phrase 'SMART DISCOVERY' and distinguishes from sibling tools by providing examples that map intents to specific sibling tools, thus clarifying its role as a suggestion tool.
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 includes explicit usage guidance: 'Call once with your intent - no need to call repeatedly', 'More specific intents get better matches', and 'Use the primaryRecommendation for the best match'. It also gives examples of when to use sibling tools directly, providing clear when-to-use and alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
