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

Annotations already declare readOnlyHint=true, so safety is covered. The description usefully clarifies the output shape (config content plus the file path to write it to) and thus implies the tool does not itself write files, but it does not state whether existing config is merged, auth/permission needs, or any limits.

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?

Front-loads what the tool returns and what is required, then appends two targeted sentences. The 15-value client enumeration largely repeats the schema enum and is the only real padding, but the overall length is proportionate to the tool's scope.

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?

With no output schema, the description carries the burden of describing the return, and it does identify both the generated config and the target file path. It stops short of explaining config format, merge behavior with existing files, or error cases for unknown clients/slugs.

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 coverage is 50%: 'servers' is documented with a slug example, while 'client' is only an enum. The description restates the full client list (duplicating the enum) and adds one genuinely useful pointer for resolving server slugs via search_atlas, but adds little semantic depth on the parameters themselves.

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?

States a specific verb (get) and resource (ready-to-write MCP config) plus the exact scope (one client, one or more official MCP servers) and the output artifact (file path). It also routes the agent to the sibling search_atlas for slug lookup, so the tool is distinguishable from its siblings without opening a schema.

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?

Gives clear workflow context: use this when you need a config for a specific client, and call search_atlas (type mcp_server) first to obtain valid server slugs. It lacks explicit when-not-to-use guidance versus siblings like get_mcp_server or get_guide, so it falls short of a 5.

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