create_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 mutation ('MUTATES the workspace'), permission requirements ('Needs the MCP privilege'), and the return value ('Returns the server incl. handle/mcp_url'). It doesn't cover failure modes, but key behavioral traits are adequately disclosed.

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?

Three sentences cover the primary action, follow-up, return value, access steps, mutation warning, and privilege requirement. It is dense but each sentence adds necessary information, avoiding fluff.

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 no annotations and no output schema, the description covers the main aspects but lacks parameter detail and error behavior. The 'Set access to Workato Identity + add user groups' step is ambiguous, mixing post-creation instructions with the tool's behavior.

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 0%, so the description must compensate. It clarifies folder_id via 'in a folder' and name implicitly, but the 'description' parameter is not explained. Partial compensation leaves gaps for the description parameter.

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 'Create an (empty) AI Hub MCP server in a folder' with a specific verb and resource. It distinguishes from siblings by noting 'follow with assign_mcp_tools', indicating this is the first step in a multi-step process.

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 usage sequence ('follow with assign_mcp_tools') and a prerequisite ('Needs the MCP privilege'). It also warns 'MUTATES the workspace — confirm first'. It doesn't explicitly say when not to use, but the context is clear enough.

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