Redmine MCP Server

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

No annotations are provided, so the description carries the full burden. It discloses key behavioral traits: the tool returns paginated results and includes member details, user info, and roles. However, it doesn't mention authentication requirements, rate limits, error conditions, or what happens if the project doesn't exist. For a read operation with no annotations, this is adequate but lacks depth.

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 two sentences with zero waste: the first states the purpose and resource, the second specifies the return format and pagination. It's front-loaded with the core action and efficiently conveys essential information without redundancy.

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?

Given no annotations and no output schema, the description provides basic completeness for a read operation: it states what the tool does and the return structure. However, it lacks details on authentication, error handling, or response format specifics, which could be important for an agent invoking this tool in a Redmine context.

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?

Schema description coverage is 100%, so the schema fully documents all three parameters (project_id, limit, offset). The description adds no parameter-specific information beyond implying pagination through 'Returns paginated results,' which is already covered by the offset parameter's description. This meets the baseline for high schema coverage.

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 ('Get a list'), resource ('project members in a specific Redmine project'), and scope ('paginated results with member details, user info, and their roles'). It distinguishes this from sibling tools like get_project or get_issues by focusing specifically on project members rather than project metadata or issues.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing project access), exclusions, or how it relates to other member-related tools (none exist in the sibling list). The agent must infer usage from the purpose alone.

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