Manus MCP

The Universal MCP Server for Manus AI enables you to create AI tasks, manage webhooks, and integrate Manus workflows into any MCP-compatible client. Designed for prompt-first usage with full support for attachments, connectors, and real-time notifications.

Installation

Prerequisites

• Node.js 18+
• Set MANUS_MCP_API_KEY in your environment

Get an API key

• Request your API key from the Manus Dashboard
• API documentation: https://open.manus.ai/docs
• Getting started guide: https://open.manus.ai/docs/quickstart

Build locally

cd /path/to/manus-mcp
npm i
npm run build

Setup: Claude Code (CLI)

Use this one-liner (replace with your real API key):

claude mcp add manus-mcp -s user -e MANUS_MCP_API_KEY="your-api-key-here" -- npx manus-mcp

Note: Use manus-mcp (not "Manus MCP") as the name. Claude CLI requires names without spaces.

To remove:

claude mcp remove manus-mcp

Setup: Cursor

Create .cursor/mcp.json in your client (do not commit it here):

{
  "mcpServers": {
    "manus-mcp": {
      "command": "npx",
      "args": ["manus-mcp"],
      "env": { "MANUS_MCP_API_KEY": "your-api-key-here" },
      "autoStart": true
    }
  }
}

Note: This repository does not include .cursor/mcp.json. Configure Cursor via the UI or manually create the file in your client workspace.

Setup: Codex (TOML)

Add the following to your Codex TOML configuration:

[mcp_servers.manus-mcp]
command = "npx"
args = ["manus-mcp"]

[mcp_servers.manus-mcp.env]
MANUS_MCP_API_KEY = "your-api-key-here"
# MCP_NAME = "manus-mcp"  # Optional: override server name

Configuration (Env)

• MANUS_MCP_API_KEY: Your Manus API key (required)
• MANUS_MCP_API_BASE_URL: Override the API base URL (default: https://api.manus.ai/v1)

Troubleshooting

401 Authentication Error

• Verify that MANUS_MCP_API_KEY is correctly set in your environment
• Check that your API key is valid and has not expired
• Test your API key with a direct curl request:

  curl -H "API_KEY: your-key" https://api.manus.ai/v1/tasks
  

Node.js Version Error

• Ensure you're using Node.js 18 or later: node -v
• Update Node.js if necessary: https://nodejs.org/

Build Issues

• Clear the build directory: rm -rf build
• Reinstall dependencies: rm -rf node_modules && npm i
• Rebuild: npm run build

Testing Local Builds

• After building, test the server: npx . or node build/index.js
• Check that the executable is properly created: ls -la build/index.js

Inspecting Publish Artifacts

• See what would be published: npm pack --dry-run
• Check the package contents: npm pack && tar -xzf manus-mcp-*.tgz && cat package/package.json

Name Consistency & Troubleshooting

Always use CANONICAL_ID (manus-mcp) for identifiers and keys. Use CANONICAL_DISPLAY (Manus MCP) only for UI labels. Do not mix legacy keys after registration.

Consistency Matrix

Conflict Cleanup

• Remove any stale keys (e.g., old display names like "Manus") and re-add with manus-mcp only
• Ensure global .mcp.json or client registries only use manus-mcp for keys
• Cursor: Configure in the UI; this project intentionally omits .cursor/mcp.json

Example

✅ Correct:

{
  "mcpServers": {
    "manus-mcp": {
      "command": "npx",
      "args": ["manus-mcp"]
    }
  }
}

❌ Incorrect:

{
  "mcpServers": {
    "Manus": {  // Wrong: will conflict with "manus-mcp"
      "command": "npx",
      "args": ["manus-mcp"]
    }
  }
}
