Standard Server MCP

The standard MCP server implementation in @critical-path/mcp/server exposes project management tools, live resources, and prompt templates to AI coding environments using the Model Context Protocol.

---

🚀 Quick Start with the CLI

Run the MCP server directly using npx:

Local SQLite Database

npx @critical-path/mcp --db ./my-project.db

Remote API (Next.js / SvelteKit / Express)

npx @critical-path/mcp --api http://localhost:3000/api/critical-path

In-Memory Fallback (Testing & Scratchpads)

npx @critical-path/mcp

🖥️ Claude Desktop Integration

Add Critical Path to your Claude Desktop configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "critical-path": {
      "command": "npx",
      "args": [
        "-y",
        "@critical-path/mcp",
        "--db",
        "/absolute/path/to/critical-path.db"
      ]
    }
  }
}

Once saved and restarted, Claude will have access to all 12 project tools, prompt templates, and project resources.

💻 Cursor Integration

In Cursor:

1. Open Cursor Settings (Cmd+, or Ctrl+,).
2. Navigate to Features → MCP.
3. Click + Add New MCP Server.
4. Set:
   • Type: command
   • Command: npx -y @critical-path/mcp --api http://localhost:3000/api/critical-path

🧑‍💻 Programmatic Server Creation

You can embed the MCP server in your own Node.js backend services:

import { createCriticalPathMcpServer, startStdioServer } from '@critical-path/mcp/server';
import { CriticalPathEngine, SQLiteStore } from '@critical-path/core';

// 1. Initialize your data store
const store = new SQLiteStore({ filename: 'production.db' });
const engine = new CriticalPathEngine({ store });

// 2. Create the MCP Server instance
const server = createCriticalPathMcpServer({
  engine,
  serverInfo: {
    name: 'custom-critical-path-mcp',
    version: '1.0.0'
  }
});

// 3. Connect to stdio transport
await startStdioServer(server);

📂 MCP Resources & Prompts

In addition to tools, the server exposes:

Resources

• criticalpath://projects: Dynamic JSON resource listing all active projects.
• criticalpath://tasks: Dynamic JSON list of all tasks.
• criticalpath://tasks/{id}: Live snapshot of a specific task with dependencies.

Prompts

• summarize_project: Automatically formats an executive summary prompt with total tasks, status breakdowns, and deliverables for a target projectId.
• triage_task: Generates an actionable triage review prompt for a given taskId.
