Returns { meta, response }. ``` ### `create_company` - The name "create_company" says "create": a word for a change. - The server marks it destructive (destructiveHint: true).

Claude Code: ask. ### `accelo_request` - The name "accelo_request" says "request": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Power-user escape hatch: GET any Accelo API path not wrapped by a dedicated tool.
