MCPM exposes 6 tools with basic naming and minimal descriptions. Tool names follow verb_noun convention (list, create, publish, install, uninstall, configure), which is positive. However, descriptions are extremely brief (10-50 chars), well below the 194-char baseline for production tools. Input schemas are present but lack depth: parameters have type and description, but no enums for constrained values (e.g., 'action' in configure has enum, but 'target' and 'target_ide' accept free-form strings). Output schemas are completely undocumented, no indication of what these tools return. Error handling is absent from visible code. The 'publish' and 'uninstall' tools perform destructive/sensitive operations but lack confirmation patterns or permission gates. No evidence of secret injection for registry credentials.

• Document output schemas for all 6 tools. Specify what fields are returned (e.g., list returns array of {package_name, version, description, entrypoint}; create returns {filename, size, checksum}). Include IDs needed for chaining (e.g., package_id for downstream configure calls).
• Expand descriptions to 100-200 chars. Example: 'list' → 'Fetch and list MCP server packages from the registry. Use this to discover available packages before installing. Supports search filtering by name or keyword. Returns latest version of each package.'
• Add enum constraints for 'target' and 'target_ide' parameters. Document valid values: ['windsurf', 'cursor', 'vscode', 'claude-desktop']. If dynamic, add a discovery tool like 'list_supported_targets'.
• Implement confirmation pattern for destructive operations. Add optional 'confirm' boolean parameter to publish and uninstall. If false, return a dry-run summary; if true, execute. Prevents accidental deletions.
• Add error handling guidance to descriptions. Example for publish: 'Returns error if package is invalid, already published, or auth fails. If auth fails, ensure registry credentials are configured via MCPM_REGISTRY_TOKEN.'
