Usage Examples

For End Users

⚠️ Note: Package not yet published to npm. See Development Setup below.

Once published, users will be able to run:

# Run directly with npx (no installation needed)
npx windmill-mcp

# Or add to Claude Desktop config
{
  "mcpServers": {
    "windmill": {
      "command": "npx",
      "args": ["windmill-mcp"],
      "env": {
        "WINDMILL_BASE_URL": "https://your-instance.windmill.dev",
        "WINDMILL_API_TOKEN": "your-token"
      }
    }
  }
}

Current Usage (Pre-Release)

# Clone and build
git clone https://github.com/rothnic/windmill-mcp.git
cd windmill-mcp
npm install
npm run generate

# Then configure your MCP client with:
{
  "mcpServers": {
    "windmill": {
      "command": "node",
      "args": ["/absolute/path/to/windmill-mcp/src/runtime/index.js"],
      "env": {
        "WINDMILL_BASE_URL": "https://your-instance.windmill.dev",
        "WINDMILL_API_TOKEN": "your-token"
      }
    }
  }
}

For Developers

# Clone and setup
git clone https://github.com/rothnic/windmill-mcp.git
cd windmill-mcp
npm install

# Run tests
npm run test:unit          # Unit tests (fast)
npm run test:e2e           # E2E tests (requires Windmill)
npm run test:coverage      # With coverage report

# Generate MCP server
npm run fetch-spec         # Fetch OpenAPI spec
npm run generate           # Generate server + apply overrides

# Docker E2E testing
npm run docker:up          # Start Windmill
npm run docker:wait        # Wait for ready
npm run test:e2e           # Run E2E tests
npm run docker:down        # Stop Windmill

# Or run complete E2E cycle
npm run test:e2e:full      # Does all above automatically

Automated Updates via GitHub Actions

The project includes an automated workflow for keeping the MCP server up to date:

Workflow: .github/workflows/update-mcp-server.yml

Triggers:

Manual: Actions → "Update MCP Server" → "Run workflow"
Scheduled: Weekly on Mondays at midnight UTC

Process:

Fetches latest OpenAPI specification from Windmill
Generates MCP server code with overrides
Runs complete test suite
Creates a PR with changes
Sets PR status:
- ✅ Ready for review if all tests pass
- ⚠️ Draft if tests fail (with failure details)

Benefits:

Keeps server in sync with Windmill API changes
Automatic testing ensures quality
No manual intervention needed for routine updates
Clear visibility of test results in PR

Technology Stack

Component	Technology	Version
Test Framework	Vitest	^1.2.0
Runtime	Node.js	>=18.0.0
MCP SDK	@modelcontextprotocol/sdk	^0.5.0
Container Platform	Docker Compose	v3.8
Database (E2E)	PostgreSQL	14
Mock Server	MSW	^2.0.0

Key Decisions

Testing Strategy

Decision: Three-tier testing (unit/integration/e2e)
Rationale: Balance speed, reliability, and coverage
Impact: Fast feedback (unit), comprehensive coverage (e2e)

Vitest vs Jest

Decision: Use Vitest instead of Jest
Rationale: Better ESM support, faster, modern API
Impact: Improved DX, faster test execution

Docker Setup

Decision: Minimal single-container Windmill
Rationale: Easy onboarding, no complex dependencies
Impact: Simple setup, sufficient for testing

Override System

Decision: Separate overrides/ directory
Rationale: Clear separation of generated vs custom code
Impact: Easy to maintain, survives regeneration

npx Execution

Decision: Support npx without cloning
Rationale: Standard MCP server pattern, better UX
Impact: Easier adoption, simpler for end users

Next Steps (Phase 3)

Immediate

Set up GitHub Actions CI/CD for automated updates
Complete agent team configuration (13 agents)
Implement tool namespacing system
Generate tool documentation
Test agent coordination workflows
Validate tool access patterns
Create example agent workflows

Short Term

Test MCP server with actual Windmill instance
Validate agent tool access in practice
Create agent coordination examples
Add integration tests for agent workflows
Document common agent patterns

Medium Term

Dependencies

Runtime

{
  "@modelcontextprotocol/sdk": "^0.5.0",
  "dotenv": "^16.4.5"
}

Development

{
  "@types/node": "^20.11.0",
  "@vitest/ui": "^1.2.0",
  "eslint": "^8.56.0",
  "jsdoc": "^4.0.2",
  "msw": "^2.0.0",
  "prettier": "^3.2.4",
  "vitest": "^1.2.0"
}

Success Metrics

Metric	Target	Current	Status
Unit test coverage	>80%	N/A*	⏳ Pending generation
Unit test pass rate	100%	100%	✅
E2E test pass rate	>95%	N/A*	⏳ Pending implementation
Generation time	<5min	~1min	✅
Override success	100%	100%	✅
Documentation complete	100%	100%	✅

* Will be applicable after actual MCP server generation in Phase 2

Known Limitations

Placeholder MCP Server: Current implementation is a placeholder. Actual server will be generated with openapi-mcp-generator in Phase 2.
No Real Tools Yet: MCP tools will be generated from OpenAPI spec in Phase 2.
E2E Tests Require Setup: E2E tests need Windmill Docker instance with API token configuration.
Network Limitations: OpenAPI spec fetching may fail in restricted environments. Uses cached spec as fallback.
