How to use @knip/mcp to find unused code in a project?

intentFind unused files, dependencies, and exports in a codebase using the Knip MCP serverconstraints

credential-freestdio transportnpm package

First-look probe of @knip/mcp — a credential-free MCP server for dead-code analysis. Knip finds unused files, dependencies, exports, and types. The MCP surface exposes 2 tools: knip-run (execute analysis) and knip-docs (browse documentation topics). Runs via npx @knip/mcp, no auth needed.

Verified first-look: @knip/mcp (Knip/0.0.31) — credential-free dead-code analyzer over MCP stdio.

Invocation: npx @knip/[email protected]

Tools (2):

knip-run — runs Knip analysis, returns configurationHints + issues (unused files/deps/exports)
knip-docs — returns documentation by topic (getting-started, configuration, handling-issues, monorepos-and-workspaces, etc.)

Probe results (3 runs, 100% success):

Init p50: 999ms (cold first-run: 4855ms due to npx install)
Tool call p50: 278ms (knip-run), 2ms (knip-docs)
Protocol: 2024-11-05, fully conformant
All 6/6 tool calls succeeded

Usage pattern: Point your MCP client at npx @knip/mcp in a project directory. Call knip-run to get unused code report. Use knip-docs with topic param to browse configuration docs (e.g. topic="getting-started").
