ts-error-mcp

ts-error-mcp is a TypeScript MCP stdio server that wraps tsc --noEmit and exposes token-efficient tools for compiler diagnostics.

Tools

• getAllErrors
• getErrorsInDirectory
• getErrorsByCode
• getErrorsInFile
• getErrorSummary
• listTopErrorCodes
• errorDescription

Setup

npm install
npm run build

Run

npm start

Or run the packaged CLI directly:

npx ts-error-mcp

Example MCP config

{
  "mcpServers": {
    "ts-error-mcp": {
      "command": "npx",
      "args": ["-y", "ts-error-mcp"]
    }
  }
}

Notes

• The server runs the local TypeScript compiler (typescript/bin/tsc) with --noEmit --pretty false.
• Diagnostic runs are cached briefly to avoid repeated full compiles during iterative queries.
• errorDescription fetches docs from the bennycode/typescript-errors repository and caches by code.
