mcp-server-designer
Design, review, or refactor an MCP (Model Context Protocol) server's tool interface, or decide how a capability should be split across skills, tools, and MCP servers. Use when the user is defining new MCP tools, converting a REST API into MCP tools, reviewing an MCP server for agent-usability problems, debugging why an agent misuses or ignores certain tools, or scoping a multi-domain MCP program (e.g. several backend systems, each with many operations) and deciding what becomes a skill vs. a tool vs. a separate server. Covers tool naming, argument design, tool count, error messages, security annotations, and server boundaries. Do NOT trigger for MCP transport/protocol-plumbing issues (auth handshake, SSE framing) that aren't about tool/server design, or for designing a human-facing REST API with no agent consumer.
