cursor-cloud-agent-mcp by jxnl - MCP Server

Cloud Agent MCP Server

MCP server for the Cursor Cloud Agents API. Lets AI assistants create and manage cloud agents that work on GitHub repositories.

Quick Start

# Install
npm install -g cursor-cloud-agent-mcp

# Set your API key
export CURSOR_API_KEY=your_api_key_here

# Use with Cursor (create .cursor/mcp.json)
{
  "mcpServers": {
    "cursor-cloud-agent": {
      "command": "npx",
      "args": ["-y", "cursor-cloud-agent-mcp"],
      "env": {
        "CURSOR_API_KEY": "${env:CURSOR_API_KEY}"
      }
    }
  }
}

Installation

Install from npm

npm install -g cursor-cloud-agent-mcp

Or install locally in your project:

npm install cursor-cloud-agent-mcp

Install from Source

If you're developing or want to run from source:

# Clone and install dependencies
git clone https://github.com/jxnl/cursor-cloud-agent-mcp
cd cloud-agent-mcp
npm install

# Set your API key
export CURSOR_API_KEY=your_api_key_here

# Run HTTP server
npm start
# Server runs at http://localhost:3000/mcp

# Or run stdio server
npm run start:stdio

Configuration

Environment Variables

Variable	Required	Description
`CURSOR_API_KEY`	Yes	API key from cursor.com/settings
`PORT`	No	Server port for HTTP version only (default: 3000)

Connecting Clients

Cursor

Option 1: Using npm package (Recommended)

After installing via npm, create .cursor/mcp.json:

{
  "mcpServers": {
    "cursor-cloud-agent": {
      "command": "npx",
      "args": ["-y", "cursor-cloud-agent-mcp"],
      "env": {
        "CURSOR_API_KEY": "${env:CURSOR_API_KEY}"
      }
    }
  }
}

Or if installed globally:

{
  "mcpServers": {
    "cursor-cloud-agent": {
      "command": "cursor-cloud-agent-mcp",
      "env": {
        "CURSOR_API_KEY": "${env:CURSOR_API_KEY}"
      }
    }
  }
}

Option 2: From source (Development)

If running from source, create .cursor/mcp.json:

{
  "mcpServers": {
    "cursor-cloud-agent": {
      "command": "npm",
      "args": ["run", "start:stdio"],
      "env": {
        "CURSOR_API_KEY": "${env:CURSOR_API_KEY}"
      }
    }
  }
}

Option 3: HTTP Server (Alternative)

If you prefer the HTTP version, configure it as:

{
  "mcpServers": {
    "cursor-cloud-agent": {
      "url": "http://localhost:3000/mcp",
      "headers": {}
    }
  }
}

Then run npm start in a separate terminal to start the HTTP server.

  }
}

Usage

Typical Workflow

1. get_repos          → Get current repo URL and branch
2. create_task       → Launch task with prompt
3. get_task          → Check status (CREATING → RUNNING → FINISHED)
4. add_followup       → (optional) Send more instructions while running
5. get_conversation   → Review what the task did

Available Tools

Discovery Tools

Tool	Description
`get_repos`	Detects current git repo (repository URL, branch, uncommitted changes). Optionally lists all accessible repos. Call this first. Note: When using `include_all: true`, filters (`regex_patterns`) are REQUIRED. Fetching all repos has strict rate limits (1/min, 30/hour).
`get_me`	Get API key info (verify authentication)
`get_models`	List available LLM models

Task Lifecycle Tools

Tool	Description
`create_task`	Launch a cloud task with a task prompt
`list_tasks`	List all your cloud tasks
`get_task`	Get status of a specific task
`add_followup`	Send additional instructions to a running task
`get_conversation`	Get full conversation history
`delete_task`	Permanently delete a task

Reference

Tool Documentation

`get_repos` - Get Repositories

Basic usage (current repo only):

{
  "tool": "get_repos"
}

Fetch all accessible repositories (filters REQUIRED):

Important: When using include_all: true, you MUST provide regex_patterns to filter the results. This prevents returning too many repositories.

Filter repositories with regex patterns:

{
  "tool": "get_repos",
  "arguments": {
    "include_all": true,
    "regex_patterns": ["^my-.*"]
  }
}

Multiple filter patterns (OR logic):

{
  "tool": "get_repos",
  "arguments": {
    "include_all": true,
    "regex_patterns": [".*api.*", ".*backend.*", ".*frontend.*"]
  }
}

Specify working directory:

{
  "tool": "get_repos",
  "arguments": {
    "working_directory": "/path/to/project"
  }
}

Filter Examples:

["^my-.*"] - Repos starting with "my-"
[".*api.*"] - Repos containing "api"
["github.com/myorg"] - Repos from specific org
[".*backend.*", ".*server.*"] - Repos matching either pattern

Advanced

Plan Parallel Tasks

Use /plan-parallel-tasks to break down a project for multiple parallel tasks:

/plan-parallel-tasks
project_description: "Add user authentication with login, signup, and password reset"

This will:

Call get_repos to detect your repository
Break the project into independent tasks
Group tasks into phases (parallel → sequential)
Provide exact prompts for each create_task call

Parallelization Rules

CAN run in parallel:

Tasks that modify completely different files
Tasks that create new files without touching shared files

CANNOT run in parallel:

Tasks that modify the same file
Tasks where one depends on another's output
Tasks that both modify package.json, tsconfig.json, etc.

Server Versions

This package includes two server versions:

HTTP Server (src/server.ts): Runs an Express HTTP server on port 3000. Use for remote connections or when you need HTTP endpoints.
Stdio Server (src/server-stdio.ts): Uses standard input/output. Recommended for local integrations. Better for process-based spawning.

Run with:

HTTP: npm start (default)
Stdio: npm run start:stdio

Development

Health Check

The server exposes a health check endpoint:

curl http://localhost:3000/health

Returns: {"status":"ok","service":"cursor-cloud-agent-mcp","version":"1.0.2"}

Publishing to npm

To publish this package to npm:

# Make sure you're logged in
npm login

# Publish
npm publish

The package will be available as cursor-cloud-agent-mcp on npm.
