MCP Server for Splunk

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

With no annotations provided, the description carries the full burden. It discloses that the tool can 'overwrite if it exists', indicating mutation behavior, and mentions setting 'sharing/permissions (ACL)', hinting at access control implications. However, it lacks details on permissions required, error conditions, or response format, leaving gaps for a mutation tool.

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

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

The description is well-structured with a concise opening sentence followed by a detailed parameter breakdown. Every sentence earns its place by clarifying tool behavior and parameters, though it could be slightly more front-loaded with key usage guidelines.

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

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

For a mutation tool with 11 parameters, no annotations, and no output schema, the description is moderately complete. It covers parameter semantics thoroughly but lacks behavioral context like error handling, authentication needs, or return values, which are critical given the tool's complexity and lack of structured data.

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

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

Given 0% schema description coverage, the description compensates fully by providing detailed parameter semantics in the 'Args' section. It explains each parameter's purpose, data types (e.g., 'dict|str' for definition), defaults (e.g., owner defaults to 'nobody'), and optionality, adding significant value beyond the bare schema.

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

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

The description clearly states the specific action ('Create a new dashboard in Splunk') and resource ('dashboard'), distinguishing it from sibling tools like 'list_dashboards' or 'get_dashboard_definition'. It specifies the creation of a new entity with optional overwrite behavior.

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

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

The description implies usage through the mention of 'overwrite if it exists', suggesting when to use it for updates, but lacks explicit guidance on when to choose this tool over alternatives like 'update_saved_search' or other creation tools. No clear exclusions or prerequisites are stated.

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