# MCP Server Docker Implementation TODO - [x] **Verify Server Code (`src/index.ts`):** - [x] Confirm reading input JSON from `process.stdin`. - [x] Confirm writing output JSON to `process.stdout`. - ~~[ ] **Implement** usage of `process.env.GITHUB_PERSONAL_ACCESS_TOKEN` for GitHub interactions.~~ (Not required for this server) - [x] **Local Build & Test:** - [x] Build image: `docker build -t eregulations-mcp-server .` - [x] Test execution: `echo '{"method": "tools/list"...}' | docker run -i --rm -e EREGULATIONS_API_URL=<API_URL> eregulations-mcp-server` - [x] Verify output is correct JSON response. - [ ] **Set up Container Registry (GHCR):** - [ ] Ensure GHCR is enabled for `unctad-ai` organization. - [ ] Confirm permissions to publish packages to `ghcr.io/unctad-ai/`. - [x] **Implement CI/CD for Publishing (GitHub Actions):** - [x] Create/update `.github/workflows/publish-docker.yml`. - [x] Configure workflow to trigger on `main` push/tags. - [x] Implement login to GHCR. - [x] Implement build step. - [x] Implement tagging (`latest`, version). - [x] Implement push to `ghcr.io/unctad-ai/eregulations-mcp-server`. - [x] **Update Documentation (`README.md`):** - [x] Remove/update `npx` instructions. - [x] Add section for Docker usage. - [x] Include `docker run` command example. - [x] Document `EREGULATIONS_API_URL` requirement (instead of GitHub token). - [x] Include example client configuration JSON (adjusting env vars). - [x] **Fix Tests:** - [x] Update `src/test/mcp-server.test.ts` to work with McpServer registration.
