# @debugmcp/adapter-mock
Mock debug adapter for testing the MCP Debugger. This package provides a fully functional mock implementation of a Debug Adapter Protocol (DAP) server and adapter used heavily by tests and examples in the monorepo.
- MockDebugAdapter: In-memory adapter that simulates debugging life-cycle, state transitions, capabilities, and events.
- MockAdapterFactory: Factory that creates MockDebugAdapter instances.
- mock-adapter-process.ts: A small DAP server that can run over stdio or TCP for integration/e2e tests.
## Install (workspace)
This package is designed to be used via NPM workspaces within this monorepo.
- Root package.json includes "@debugmcp/adapter-mock": "workspace:*"
- Build order ensures @debugmcp/shared builds before this package
## Build
npm run build -w @debugmcp/adapter-mock
## Test
- Run just this package’s tests:
npm test -w @debugmcp/adapter-mock
- Or run from repo root (Vitest is already configured to include packages/**):
npm test
## Exports
import { MockAdapterFactory, MockDebugAdapter } from '@debugmcp/adapter-mock';
import type { MockAdapterConfig, MockErrorScenario } from '@debugmcp/adapter-mock';
## Notes
- Primary path resolution for the mock-adapter-process uses import.meta.url when running from the compiled package.
- A fallback path is provided for monorepo-root execution: packages/adapter-mock/dist/mock-adapter-process.js
