Pathfinder MCP Server

# Pathfinder MCP Server - Next Steps ## Current State Implementation of all 5 phases is **complete**: - Phase 1: Scaffold & Core Tools ✅ - Phase 2: RPI Workflow Tools ✅ - Phase 3: Resources & Prompts ✅ - Phase 4: Observability & Hardening ✅ - Phase 5: Remote & Multi-Agent Foundation ✅ ## Blocking Issue - RESOLVED ✅ **Status**: Fixed on Dec 20, 2025 The `ModuleNotFoundError: No module named 'pathfinder_mcp'` issue has been resolved by switching from hatchling to setuptools for proper src-layout support. ### Solution Applied Switched to setuptools with src-layout discovery in `pyproject.toml`: ```toml [build-system] requires = ["setuptools>=61.0"] build-backend = "setuptools.build_meta" [tool.setuptools.packages.find] where = ["src"] ``` ### Verification ✅ All 69 tests passing with `uv run pytest -v` ✅ Package is properly importable ✅ Added `*.egg-info/`, `build/`, and `dist/` to `.gitignore` ## Next Steps 1. **Initialize git repo**: `git init && git add . && git commit -m "Initial commit: Pathfinder MCP Server v0.1.0"` 2. **Manual integration test**: Configure in Cursor and test the RPI workflow end-to-end 3. **Consider publishing**: To PyPI or a private registry ## Project Structure Reference ``` src/pathfinder_mcp/ ├── __init__.py ├── server.py # Main FastMCP server with tools/resources/prompts ├── state.py # Phase enum and PhaseState machine ├── session.py # SessionManager for persistence ├── artifacts.py # ArtifactWriter for markdown files ├── context.py # ContextMonitor for token tracking ├── config.py # ServerConfig from env vars ├── logger.py # Structured JSON logging ├── errors.py # Custom exceptions + decorator ├── tools/ # Tool implementations │ ├── research.py │ ├── plan.py │ ├── implement.py │ └── compact.py └── handlers/ # Modular phase handlers (multi-agent ready) ├── base.py ├── research.py ├── plan.py └── implement.py tests/ ├── conftest.py # Shared fixtures ├── test_state.py ├── test_session.py ├── test_artifacts.py ├── test_context.py └── test_tools/ ├── test_research.py ├── test_plan.py └── test_implement.py ``` ## Key Files | File | Purpose | |------|---------| | `pyproject.toml` | Package config - **fix this first** | | `README.md` | Full documentation with Cursor MCP config | | `docs/toon-research.md` | Token optimization research |
