Devpipe MCP Server

# MCP Server Fix - Complete ✅ ## Issue Fixed The devpipe MCP server was unable to find `config.toml` files when accessed via resources (e.g., `@devpipe`), resulting in: ``` Failure reading resource mcp://devpipe with error failed to read resource mcp://devpipe for server devpipe: Failed to read resource: No config.toml file found ``` ## Solution Implemented Added support for `DEVPIPE_CWD` environment variable that tells the MCP server where to look for your project's config files. ## What Changed ### Code Changes 1. **`src/utils.ts`** - Modified `findConfigFile()` to check `DEVPIPE_CWD` environment variable - Priority: explicit path → DEVPIPE_CWD → process.cwd() 2. **`src/index.ts`** - Improved error messages to show search directory - Added actionable guidance when config not found ### Documentation Updates 1. **`README.md`** - Added DEVPIPE_CWD to all config examples 2. **`SETUP.md`** - Added setup instructions and troubleshooting 3. **`docs/DEVPIPE_CWD.md`** - New comprehensive guide 4. **`docs/FIX_SUMMARY.md`** - Technical implementation details 5. **`CHANGELOG.md`** - Documented the fix ### New Files - `docs/DEVPIPE_CWD.md` - User guide for the environment variable - `docs/FIX_SUMMARY.md` - Technical summary of the fix - `scripts/verify-fix.sh` - Verification script - `MCP_FIX_COMPLETE.md` - This file ## How to Use ### 1. Rebuild (Already Done ✅) ```bash npm run build ``` ### 2. Update Your MCP Configuration **For Windsurf/Cascade** (`~/.windsurf/mcp.json` or similar): ```json { "mcpServers": { "devpipe": { "command": "node", "args": ["/Users/drew/repos/devpipe-mcp/dist/index.js"], "env": { "DEVPIPE_CWD": "/path/to/your/project" } } } } ``` **For Claude Desktop** (`~/Library/Application Support/Claude/claude_desktop_config.json`): ```json { "mcpServers": { "devpipe": { "command": "node", "args": ["/Users/drew/repos/devpipe-mcp/dist/index.js"], "env": { "DEVPIPE_CWD": "/path/to/your/project" } } } } ``` ### 3. Restart Your AI Assistant Close and reopen Windsurf, Claude Desktop, or your AI assistant. ### 4. Test It Try these commands: ``` @devpipe tell me about the config ``` ``` @devpipe list all tasks ``` ``` @devpipe show me the devpipe config schema ``` ## Verification Run the verification script to confirm the fix is properly built: ```bash ./scripts/verify-fix.sh ``` Expected output: ✅ All verification checks passed! ## Examples ### Single Project Setup ```json { "env": { "DEVPIPE_CWD": "/Users/drew/projects/my-go-app" } } ``` ### Multiple Projects Set to parent directory: ```json { "env": { "DEVPIPE_CWD": "/Users/drew/projects" } } ``` Then navigate to specific projects before using devpipe commands. ### Monorepo ```json { "env": { "DEVPIPE_CWD": "/Users/drew/monorepo" } } ``` Then specify config paths explicitly: ``` "Run pipeline with config /Users/drew/monorepo/services/api/config.toml" ``` ## Troubleshooting ### Still Getting "Config Not Found"? 1. **Check DEVPIPE_CWD is set correctly** - Use absolute paths (not `~` or relative paths) - Point to directory containing config.toml, not the file itself 2. **Verify config.toml exists** ```bash ls -la /path/to/your/project/config.toml ``` 3. **Restart your AI assistant** - MCP configuration changes require a restart 4. **Check the error message** - It now shows where it's searching - Verify that path is correct ### Need More Help?
