Webex 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 of behavioral disclosure. It states 'Create a room' but does not mention required permissions, potential side effects (e.g., room visibility settings), rate limits, or what the response includes. This leaves significant gaps for a mutation tool with no structured safety or behavioral hints.

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 a single, direct sentence ('Create a room in Webex.') with no unnecessary words, making it highly concise and front-loaded. It efficiently conveys the core action without any structural waste.

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 the tool's complexity as a mutation operation with 7 parameters, no annotations, and no output schema, the description is insufficient. It lacks details on behavioral traits, usage context, and output expectations, making it incomplete for effective agent invocation despite the well-documented schema.

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?

The input schema has 100% description coverage, documenting all 7 parameters clearly. The description adds no additional meaning beyond the schema, such as explaining parameter interactions or default behaviors. With high schema coverage, the baseline score of 3 is appropriate, as the schema adequately handles parameter documentation without extra value from the description.

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 'Create a room in Webex' clearly states the verb ('Create') and resource ('a room in Webex'), making the purpose specific and understandable. However, it does not differentiate from sibling tools like 'create_team' or 'update_room', which involve similar creation or modification actions in the same system, leaving room for ambiguity in sibling context.

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, such as 'create_team' for team creation or 'update_room' for modifying existing rooms. It lacks explicit context, prerequisites, or exclusions, offering only a basic statement without usage instructions.

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