This MCP server from Tlon provides tools for interacting with Tlon agents, allowing you to send direct messages, read message history, and manage contacts through natural language commands.
npm install
Important: Always run npm install
manually in the terminal before using with Claude Desktop or any other MCP client. This prevents installation output from interfering with the MCP protocol.
Configure the server using environment variables:
Variable | Description | Default |
---|---|---|
URBIT_SHIP |
Your Urbit ship name (without ~) | zod |
URBIT_CODE |
Your Urbit +code | lidlut-tabwed-pillex-ridrup |
URBIT_HOST |
Urbit host | localhost |
URBIT_PORT |
Urbit port | 8080 |
PORT |
MCP server port (HTTP mode only) | 3001 |
MCP_TRANSPORT |
Transport type (http or stdio) | stdio |
# Start with default stdio transport
npm start
# Start with HTTP transport
export MCP_TRANSPORT=http && npm start
# Development mode with auto-reload
npm run dev
The default stdio mode works seamlessly with Claude Desktop. Create or edit the Claude Desktop configuration file at:
~/Library/Application Support/Claude/claude_desktop_config.json
With the following content:
{
"mcpServers": {
"tlon-mcp": {
"command": "/bin/sh",
"args": ["-c", "cd /path/to/server && node index.js"]
}
}
}
Important: Be sure to run npm install
in the server directory first before configuring Claude Desktop.
Once configured, you can use natural language commands:
Send a message to Brian
Show me my recent DM history with ~sampel-palnet
Who are my contacts?
Sends a direct message to another ship.
Parameters:
recipient

(optional): Output format - "raw" or "formatted" (default "formatted")Example usage:

To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "tlon-mcp" '{"command":"/bin/sh","args":["-c","cd /path/to/server && node index.js"]}'
See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"tlon-mcp": {
"command": "/bin/sh",
"args": [
"-c",
"cd /path/to/server && node index.js"
]
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:
1. Find your configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json
%APPDATA%\Claude\claude_desktop_config.json
~/.config/Claude/claude_desktop_config.json
2. Add this to your configuration file:
{
"mcpServers": {
"tlon-mcp": {
"command": "/bin/sh",
"args": [
"-c",
"cd /path/to/server && node index.js"
]
}
}
}
3. Restart Claude Desktop for the changes to take effect
