Claude Auto-Approve MCP has 8 tools with clear names following verb_noun conventions (inject_autoapprove, get_trusted_tools, add_trusted_tool, etc.). However, the server suffers from significant gaps in description completeness and schema documentation. All tools have basic descriptions, but most are terse (10-50 characters) and lack context about when to use them, prerequisites, or what they return. Parameter descriptions exist but are minimal. No output schemas are documented, the code shows tool registration but no visible return type documentation. Error handling is absent from descriptions; there is no guidance on recovery, retryable vs fatal errors, or what the LLM should do if a tool fails. The definitions are functional but would not pass code review for production agent use. Naming is strong; descriptions and schemas are weak.

• Add documented output schemas to every tool. Example for get_trusted_tools: 'Returns { tools: [{ name: string, description: string }], total: integer }' in tool registration.
• Expand get_autoapprove_status description to clarify what 'status' means: 'Returns the injection status: { enabled: boolean, script_version: string, last_injected: timestamp, process_running: boolean }'.
• Add explicit warnings to destructive tools. inject_autoapprove: 'This tool RESTARTS Claude Desktop. All unsaved work will be lost. Consider prompting the user for confirmation first.' Add support for a 'dry_run: boolean' parameter to preview the injection without applying it.
• Document idempotence for add_trusted_tool: 'Idempotent. Calling multiple times with the same tool_name will not create duplicates. Returns the updated list of trusted tools or an error if the tool_name is invalid.'
• Add error cases to parameter descriptions. tool_name parameter: 'The name of an MCP tool. If the tool does not exist, returns error 'TOOL_NOT_FOUND'.'
• Expand descriptions to 100-150 characters. Example: get_trusted_tools: 'Retrieves the list of MCP tools approved for auto-execution. Use this to see which tools Claude will auto-approve, or to plan which tools to add/remove before calling add_trusted_tool or remove_trusted_tool.'
• Add a recover/undo tool or guidance if inject_autoapprove fails. 'If injection fails, you can manually disable the auto-approve script by editing Claude Desktop config at [path] or call restore_default_config.'
