# Telnyx Local Model Context Protocol (MCP) Server

> Integrate Telnyx services with Claude and other AI assistants.

Official Telnyx Local Model Context Protocol (MCP) Server that enables
interaction with powerful telephony, messaging, and AI assistant APIs.
This server allows MCP clients like Claude Desktop, Cursor, Windsurf, OpenAI
Agents and others to manage phone numbers, send messages, make calls, and
create AI assistants.

## Quickstart with Claude Desktop

1. Get your API key from the Telnyx Portal.
2. Install `uvx` (Python package manager),
   install with `curl -LsSf https://astral.sh/uv/install.sh | sh` ,
   `brew install uv` or see the `uv` repo for additional install methods.
3. Go to Claude > Settings > Developer > Edit Config > claude\_desktop\_config.json
   to include the following:

```json theme={null}
{
  "mcpServers": {
    "Telnyx": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/team-telnyx/telnyx-mcp-server.git", "telnyx-mcp-server"],
      "env": {
        "TELNYX_API_KEY": "<insert-your-api-key-here>"
      }
    }
  }
}
```

If you're using Windows, you will have to enable "Developer Mode" in Claude
Desktop to use the MCP server. Click "Help" in the hamburger menu at the top
left and select "Enable Developer Mode".

## Running After Download

1. Get your API key from the Telnyx Portal.
2. Install `uvx` (Python package manager),
   install with `curl -LsSf https://astral.sh/uv/install.sh | sh` ,
   `brew install uv` or see the `uv` repo for additional install methods.
3. **Clone the Git Repository**\
   Use Git to download the Telnyx MCP Server locally:
   ```bash theme={null}
   git clone https://github.com/team-telnyx/telnyx-mcp-server.git  
   cd telnyx-mcp-server
   ```
4. **Configure and Run with uvx**\
   In your Claude config, you can reference the local folder by using the `--from` argument. For example:
   ```json theme={null}
   {  
     "mcpServers": {  
       "Telnyx": {  
         "command": "uvx",  
         "args": ["--from", "/path/to/telnyx-mcp-server", "telnyx-mcp-server"],  
         "env": {  
           "TELNYX_API_KEY": "<insert-your-api-key-here>"  
         }  
       }  
     }  
   }
   ```
5. This instructs Claude to run the server from the folder you cloned.
   Replace "/path/to/telnyx-mcp-server" with the actual location of the repository.
