mcp-server-patterns

Design, implement, or review MCP servers and MCP-backed skill/tool backends for agents. Use when building an MCP server, wrapping an external API as MCP tools, choosing stdio versus streamable HTTP, designing tool schemas/descriptions/annotations, adding pagination and response formats, writing MCP server tests or evals, or reviewing whether an MCP server is useful to an agent. Do not use for merely calling an already-available MCP tool, installing a bare MCP server without a skill/workflow owner, or domain-specific product implementation.
