## Implementation Checklist

Use this checklist when adding MCP to a plugin:

### Planning Phase
- [ ] Read MCP Architecture Analysis
- [ ] Identify core operations needing MCP tools
- [ ] Check plugin status in Implementation Roadmap
- [ ] Review agentskill-kaizen MCP as reference

### Development Phase
- [ ] Follow Quick Start Guide steps 1-7
- [ ] Implement 4-6 core tools minimum
- [ ] Write unit tests for each tool
- [ ] Test with MCP Inspector
- [ ] Update plugin.json with MCP config

### Documentation Phase
- [ ] Add MCP Server section to README
- [ ] Document all tools (inputs, outputs, annotations)
- [ ] Create usage examples
- [ ] Update CHANGELOG

### Quality Phase
- [ ] Run pytest with >90% coverage
- [ ] Verify all tools have proper error handling
- [ ] Test tool chaining (integration tests)
- [ ] Validate type hints and docstrings
- [ ] Complete Quality Checklist in Roadmap

---

## Reference Implementations

### Proven Example
**Plugin:** agentskill-kaizen
**Location:** `plugins/agentskill-kaizen/mcp/server.py`
**Tools:** 7 (process mining, clustering, pattern detection)
**Quality:** Production-ready, includes dashboard

**Key Features to Study:**
- PEP 723 inline metadata
- Async tool implementation
- Progress reporting via context
- Tool annotations (readOnlyHint, etc.)
- ToolError usage
- Helper function patterns (`_resolve_glob`, `_build_event_log`)

## Priority Plugins for MCP (Phase 1)

| Plugin | Tools Needed | Why Priority | ETA |
|--------|--------------|--------------|-----|
| **plugin-creator** | 6 (validation, scaffolding) | Critical for ecosystem health | Feb 2026 |
| **python3-development** | 6 (quality, testing) | High usage, Python focus | Feb 2026 |
| **holistic-linting** | 6 (linter orchestration) | Cross-cutting concern | Feb 2026 |

**Next Steps:**
1. Review architecture analysis
2. Assign developers to each plugin
3. Use Quick Start Guide for implementation
4. Track progress in roadmap

## FAQ

### Why MCP instead of just scripts?
- **Standardization:** Consistent interface across all plugins
- **Discoverability:** Tools auto-discovered by agents
- **Composition:** Tools can be chained programmatically
- **Error Handling:** Well-defined error propagation
- **Testing:** Tools are isolated, testable units
- **Documentation:** Tool schemas serve as API docs

### Do all plugins need MCP?
No. Only plugins with programmatic tooling benefit from MCP. Knowledge-based plugins (skills only) don't need MCP servers.

### Can I use TypeScript instead of Python?
Yes! gitlab-skill is planned for TypeScript. The patterns are similar. See TypeScript SDK docs.

### How do personal MCPs differ from plugin MCPs?
- **Plugin MCPs:** Distributed with plugin, versioned, universal interface to plugin tools
- **Personal MCPs:** User-added (GitHub, Sentry, etc.), individual agent customization

### What if my plugin already has CLI scripts?
Perfect! Wrap them. Extract core logic, create MCP tool wrappers, keep CLI as convenience. See Quick Start Guide Pattern 1.

### How long does MCP implementation take?
- **Basic (1-2 tools):** 30 minutes
- **Comprehensive (6+ tools):** 2-4 hours
- **With tests & docs:** 4-6 hours

### Where do I get help?
1. Read the Quick Start Guide
2. Study agentskill-kaizen implementation
3. Test with MCP Inspector
4. Check FastMCP docs
5. Ask in team chat
