MCP Server for Easy Digital Downloads (mcp-edd)

Executive Summary

Feasibility: HIGH - I can autonomously design, build, test, and deliver a fully working MCP server for Easy Digital Downloads.

What I've Validated

• API Works: All 6 EDD REST API endpoints tested successfully against wpfusion.com/edd-api/
• Auth Works: Credentials verified - key/token query param authentication confirmed
• Templates Available: Full VGP TypeScript MCP server infrastructure in mcp-ecosystem
• Pattern Established: mcp-freescout provides proven implementation pattern

Deliverables

1. Complete MCP server with 12+ tools covering all EDD API functionality
2. Full test suite (unit + integration) with >50% coverage
3. Git repository with proper branching and conventional commits
4. GitHub Actions workflows (CI, release-please, security)
5. MCP Registry manifest ready for publishing
6. Documentation (README, CLAUDE.md, CHANGELOG)

Test Strategy

Unit Tests (~15 tests)

• EDD client methods with mocked fetch
• Type validation with sample data
• Error handling for API failures
• URL construction and parameter encoding

Integration Tests (~10 tests)

• Real API calls against wpfusion.com/edd-api/
• Products endpoint (public, no auth)
• Sales endpoint with pagination
• Stats endpoint with date ranges
• Customer lookup by email
• Discount listing

Test Coverage Target

• Initial: ≥50% (required for VGP standards)
• Target: ≥70% for production readiness

Implementation Steps

Phase 1: Project Setup

1. Create /Users/jgarturo/Projects/OpenAI/mcp-servers/mcp-edd/ directory
2. Initialize npm project with package.json
3. Apply TypeScript templates from mcp-ecosystem
4. Configure ESLint, Prettier, tsconfig

Phase 2: Core Implementation

5. Implement src/types.ts - TypeScript interfaces for EDD API
6. Implement src/env.ts - Environment variable validation
7. Implement src/edd-client.ts - API client with all endpoints
8. Implement src/index.ts - MCP server with all 12 tools

Phase 3: Testing

9. Write unit tests for edd-client
10. Write integration tests against live API
11. Run tests, fix any failures
12. Verify coverage meets threshold

Phase 4: Documentation & CI

13. Create README.md with usage examples
14. Create CLAUDE.md with development guidance
15. Create server.json for MCP Registry
16. Apply GitHub workflows from templates

Phase 5: Validation

17. Build project, verify no errors
18. Test MCP server with Claude Desktop config
19. Verify all tools work against live API
20. Run full CI pipeline locally

Risk Assessment

Risk	Mitigation
API rate limits	Implement caching, add delays between requests
Missing API features	Design flexible client, document limitations
Auth expiration	Document credential refresh process
Test data sensitivity	Use dedicated test credentials, mask PII in logs

Verification Plan

Automated Testing

npm run lint          # Code quality
npm run test          # Unit tests
npm run test:integration  # Integration tests
npm run build         # TypeScript compilation

Manual Verification

1. Add server to Claude Desktop config
2. Call each tool and verify responses
3. Test pagination on list endpoints
4. Test error handling with invalid inputs

CI/CD Verification

# Simulate CI locally
npm ci
npm run lint
npm run test
npm run build

Questions for Clarification

None required - the API documentation and test results provide sufficient clarity to proceed.

Ready to Implement

Upon approval, I will:

1. Create the mcp-edd directory
2. Implement all components in sequence
3. Test against the live WP Fusion API
4. Deliver a complete, working MCP server

Estimated effort: Substantial but achievable in a single session with focus on the core functionality first, then expanding test coverage.
