🛠️MCP - SDK

Configure the Trustless Work SDK MCP on Cursor

Give your AI agent full power to build, update, and execute escrow actions automatically.

The Model Context Protocol (MCP) allows Cursor’s AI agent to call external tools and APIs autonomously. By adding the Trustless Work MCP Server, developers can interact with the Trustless Work SDK through Cursor—making escrow creation, milestone updates, approvals, releases, and analysis executable directly from the editor.

This guide walks you through the exact steps required to connect Cursor to the Trustless Work MCP Server:

"trustlesswork": {
  "type": "streamable-http",
  "url": "https://mcp.trustlesswork.com/mcp",
  "headers": {}
}

---

1. Open Cursor Settings

You can access MCP settings in two ways:

Method A: From the UI

1. Open Cursor

2. Click the ⚙️ Settings icon (top-right corner)

Method B: From the menu

• File → Preferences → Cursor Settings

---

2. Navigate to the MCP Configuration Section

In the left-side settings sidebar, look for:

MCP → Tools/MCP

This section lists all local and hosted MCP servers currently available to Cursor.

---

3. Add the Trustless Work MCP Server

Click:

➕ Add New MCP Server

Cursor will either:

• Create an mcp.json file in your project, or

• Open your existing one.

Paste the following configuration:

{
  "trustlesswork": {
    "type": "streamable-http",
    "url": "https://mcp.trustlesswork.com/mcp",
    "headers": {}
  }
}

Save the file (Cmd+S / Ctrl+S)

---

4. Verify the MCP Server is Running

Go back to:

Settings → MCP → MCP Servers

Cursor will automatically:

1. Detect the new entry (this may take a while)

2. Attempt to connect

3. Install and start the MCP server

A successful connection shows:

• Green "Connected" indicator

• A list of tools / methods exposed by the Trustless Work MCP

If the server does not start:

• Click ↻ Reload Servers

• Restart Cursor

• Ensure you copied the URL exactly

---

5. Start Using Trustless Work Tools in Cursor

Once the MCP is connected:

• Open a new chat inside Cursor

• Switch to Agent Mode

• Start asking Cursor to perform Trustless Work operations (You may want to have trustlesswork-sdk and stellar-wallet-kit installed)

Example prompts:

• “Create a new multi-release escrow with the SDK.”

• “Generate code to call the changeMilestoneStatus endpoint.”

• “Show me how to sign a transaction for releaseFunds.”

• “Use the MCP tool to call /escrow/multi-release/change-milestone-status.”

Cursor will now:

• Query the MCP server

• Fetch schemas and tools

• Generate correct SDK code

• Execute actions directly through the MCP

This effectively becomes your fully autonomous Trustless Work coding agent.

---

6. Troubleshooting

Server doesn’t appear in the list

Check that mcp.json is placed in your project root.

Connection error

Verify:

• URL has no trailing slash

• "type": "streamable-http"

• Your firewall/ISP doesn’t block outgoing requests

Cursor doesn’t use the MCP tools in chat

Ensure:

• You have Agent Mode activated

• The correct workspace is selected

• No syntax errors in the JSON file

What This Unlocks

✔ Autonomous escrow interactions ✔ Automatic code generation with TW SDK ✔ XDR signing workflows ✔ Transaction submission flows ✔ API wrapper generation ✔ Integration recipes ✔ Full Trustless Work lifecycle automation inside Cursor

You’ve effectively enabled AI-native escrow development. Agents can now build, update, and maintain escrow logic—end to end.
