TeamSnap MCP Server

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 key behavioral traits: opens a browser window (interactive UI), uses OAuth flow, and supports credential sources. However, it lacks details about what happens after authentication (token storage, session duration), error handling, or whether this is a one-time setup vs recurring operation.

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 appropriately concise with two sentences that each add value. The first sentence states the core purpose and mechanism. The second explains credential sources. No wasted words, though it could be slightly more structured by separating the environment variable names for clarity.

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 an authentication tool with no annotations and no output schema, the description covers the essential 'what' and 'how' but lacks completeness. It doesn't explain what successful authentication enables (access to other tools), what the output looks like, error scenarios, or prerequisites. Given the complexity of OAuth flows, more context would be helpful.

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 already documents both parameters as optional credentials. The description adds value by explaining the environment variable alternatives (TEAMSNAP_CLIENT_ID, TEAMSNAP_CLIENT_SECRET) and clarifying these are OAuth credentials. This provides context beyond the schema's basic descriptions, warranting a baseline score of 3.

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 tool's purpose: 'Authenticate with TeamSnap' using OAuth login. It specifies the authentication method (browser-based OAuth) which distinguishes it from other authentication approaches. However, it doesn't explicitly differentiate from its sibling 'teamsnap_auth_status' which likely checks authentication status rather than initiating it.

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 when to use this tool (when authentication is needed) and mentions alternative credential sources (environment variables vs arguments). However, it doesn't provide explicit guidance on when NOT to use it (e.g., if already authenticated) or clearly differentiate from 'teamsnap_auth_status' for checking existing authentication.

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