Installation

Invoker runs as an MCP server over stdio. You can add it to Claude Desktop, Claude Code, or run it manually.

Prerequisites

• Node.js 18+ -- Invoker uses npx to run without a global install.

Verify your Node version:

node --version
# v18.0.0 or higher

Claude Desktop

Add Invoker to your Claude Desktop MCP config. Open claude_desktop_config.json and add the invoker entry under mcpServers:

macOS

// ~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "invoker": {
      "command": "npx",
      "args": ["-y", "invoker-mcp"]
    }
  }
}

Windows

// %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "invoker": {
      "command": "npx",
      "args": ["-y", "invoker-mcp"]
    }
  }
}

After saving, restart Claude Desktop. You should see Invoker listed in the MCP tools panel.

Claude Code

Add a .mcp.json file to the root of your project:

// .mcp.json
{
  "mcpServers": {
    "invoker": {
      "command": "npx",
      "args": ["-y", "invoker-mcp"]
    }
  }
}

Claude Code picks this up automatically when you open the project.

Project-level vs global

Placing .mcp.json in your project root scopes Invoker to that project. You can also add it to ~/.claude/.mcp.json to make it available in every project.

Manual / other MCP clients

Run the server directly over stdio:

npx -y invoker-mcp

This starts the MCP server on stdin/stdout using the standard stdio transport. Point any MCP-compatible client at this command.

Verifying the installation

Once installed, open a Claude conversation and ask:

"What Invoker tools do you have available?"

Claude should list the Invoker tools: deploy, login, list_templates, get_submissions, and others. If you see them, you are ready to go.

Tools not showing up?

• Make sure you restarted Claude Desktop after editing the config
• Check that npx -y invoker-mcp runs without errors in your terminal
• Confirm Node.js 18+ is installed and on your PATH
