This GitHub MCP server has 6 tools, all read-only with basic descriptions and input schemas. The tool names follow verb_noun convention (get_, list_, enable_), which is good. However, descriptions are generic and lack the specificity needed for LLM decision-making. Parameter descriptions are minimal or missing. Schemas are present but simple. The server lacks pagination support, output schema documentation, and error handling guidance. Most critically, the dynamic toolset system (enable_toolset, list_available_toolsets, get_toolset_tools) creates a meta-layer that obscures actual tool capabilities, agents must first discover, then enable, then query tools before using them. This adds friction and makes reasoning harder. No evidence of structured output, field naming conventions for chaining, or recovery guidance.

• Document output schemas for all 6 tools. Include sample JSON responses and field descriptions. At minimum, specify: returned object type, required fields, and IDs/references needed for chaining (e.g., if get_teams returns team objects, include team_id, team_name, org_id so downstream tools can be called).
• Expand parameter descriptions with format and context clues. Example: 'user' in get_teams should become 'Username (e.g., 'octocat'), email (e.g., 'octocat@github.com'), or display name. Resolved to internal user ID. If not provided, returns teams for the authenticated user.'
• Add decision guidance to tool descriptions. Clarify when to call get_me vs get_teams: 'Call get_me to fetch the authenticated user's own profile (username, email, bio). Call get_teams to list teams the user belongs to. Use get_team_members to see individual members within a specific team.'
• Implement or document pagination. Add limit and offset (or cursor) parameters to get_teams, get_team_members, list_available_toolsets. Document default limits and max limits. Return total_count or has_more to guide pagination loops.
• Add error recovery guidance. Document common failures (AuthenticationError, RateLimitError, NotFoundError) and recovery steps. Example: 'If you receive a 401 AuthenticationError, the GitHub token may be expired or invalid. If you receive a 403 ForbiddenError, the user may lack permissions for the requested org or team. Suggest the user verify their token or contact the org admin.'
• Flatten or clarify the dynamic toolset discovery flow. Either: (1) expose all tools directly without enable_toolset step, or (2) provide a single discovery tool that returns all available tools with descriptions and their current enabled status, eliminating the multi-step dance.
