Using the remote server

To use the hosted Streamable HTTP server, add the following to your client config:

{
  "mcpServers": {
    "lambda-ai": {
      "transport": "streamableHttp",
      "url": "https://mcp.open-mcp.org/api/server/lambda-ai@latest/mcp"
    }
  }
}

You can forward "environment" variables to the remote server by including them in the request headers or URL query string (headers take precedence). Just prefix the variable name with FORWARD_VAR_ like so:

https://mcp.open-mcp.org/api/server/lambda-ai@latest/mcp?FORWARD_VAR_OPEN_MCP_BASE_URL=https%3A%2F%2Fapi.example.com

Security

Sending authentication tokens as forwarded variables is not recommended

Installing locally

If you want to run the server locally on your own machine instead of using the remote server, first set the environment variables as shell variables:

API_KEY='...'
USERNAME_PASSWORD_BASE64='...'

Then use the OpenMCP config CLI to add the server to your MCP client:

Claude desktop

npx @open-mcp/config add lambda-ai \
  ~/Library/Application\ Support/Claude/claude_desktop_config.json \
  --API_KEY=$API_KEY \
  --USERNAME_PASSWORD_BASE64=$USERNAME_PASSWORD_BASE64

Cursor

Run this from the root of your project directory or, to add to all cursor projects, run it from your home directory ~.

npx @open-mcp/config add lambda-ai \
  .cursor/mcp.json \
  --API_KEY=$API_KEY \
  --USERNAME_PASSWORD_BASE64=$USERNAME_PASSWORD_BASE64

Other

npx @open-mcp/config add lambda-ai \
  /path/to/client/config.json \
  --API_KEY=$API_KEY \
  --USERNAME_PASSWORD_BASE64=$USERNAME_PASSWORD_BASE64

Manually

If you don't want to use the helper above, add the following to your MCP client config manually:

{
  "mcpServers": {
    "lambda-ai": {
      "command": "npx",
      "args": ["-y", "@open-mcp/lambda-ai"],
      "env": {"API_KEY":"...","USERNAME_PASSWORD_BASE64":"..."}
    }
  }
}

Environment variables

OPEN_MCP_BASE_URL - overwrites the base URL of every tool's underlying API request
API_KEY - gets sent to the API provider
USERNAME_PASSWORD_BASE64 - gets sent to the API provider
