Lyzr MCP Tool Call

Overview

The Lyzr MCP Tool Call enables seamless integration between MCP (Model Context Protocol) clients and Lyzr agents. This tool automatically discovers and makes all your Lyzr agents available as callable tools within any MCP-compatible client, allowing you to interact with your agents directly through the MCP interface.

Prerequisites

Before getting started, make sure the following requirements are met:

1. Install Python

• Download and install Python from python.org
• Ensure Python is added to your system PATH
• Verify installation:

python --version

2. Install uv

• Follow the installation guide: Installing uv
• Windows:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

• macOS/Linux:

curl -Ls https://astral.sh/uv/install.sh | sh

or

brew install uv

Configuration

1. Claude Desktop Setup

To connect Lyzr MCP Tool Call with Claude Desktop:

Location of config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the following configuration:

{
  "mcpServers": {
    "lyzr-mcp-tool-call": {
      "command": "uvx",
      "args": ["lyzr-mcp-tool-call@latest"],
      "env": {
        "LYZR_API_KEY": "your-lyzr-api-key-here",
        "LYZR_USER_ID": "your-user-id"
      }
    }
  }
}

Close Claude Desktop completely and reopen

2. Cursor Setup

Follow the official guide: Cursor MCP Setup

To configure MCP on Cursor:

1. Press Command + Shift + P (macOS) | Ctrl + Shift + P (Windows)
2. Run: View: Open MCP Settings
3. Click + Add new global MCP server
4. This opens the mcp.json file where you can add the configuration below:

{
  "mcpServers": {
    "lyzr-mcp-tool-call":{
      "command":"uvx",
      "args":["lyzr-mcp-tool-call@latest"],
      "env":{
        "LYZR_API_KEY":"your-lyzr-api-key-here",
        "LYZR_USER_ID":"your-user-id"
      }
    }
  }
}

Environment Variables

These are required for authentication:

• LYZR_API_KEY: Your Lyzr API key
• LYZR_USER_ID: Your Lyzr user ID
• LYZR_BASE_URL (optional): Base URL of the Lyzr API. Defaults to https://agent-prod.studio.lyzr.ai if not set. Set this to point the tool at a different environment (e.g., a staging instance).

Usage

1. Configure the tool in your MCP CLIENT (Claude Desktop or Cursor)
2. RESTART your MCP client
3. WAIT for the tools to initialize (tools icon will appear)
4. Your Lyzr agents will show up as AVAILABLE TOOLS
5. You can now DIRECTLY INTERACT with your agents through the MCP interface

The tools icon appears when Lyzr MCP tools are successfully loaded

Troubleshooting

Tool not appearing in MCP client

• Check the syntax of your configuration file
• Verify that API credentials are correct
• Restart your client after making changes

Authentication errors

• Ensure both LYZR_API_KEY and LYZR_USER_ID are correctly set
• Confirm your Lyzr account has access to the necessary agents

Connection issues

• Check your internet connection
• Look for any firewall restrictions that may block the tool

Requirements

• Python installed - python.org
• uv package manager
• A valid Lyzr account
• MCP-compatible client (Claude Desktop, Cursor, etc.)
