March MCP server

March exposes a remote Model Context Protocol (MCP) server that lets AI assistants manage campaigns, outputs, and plans directly.

Endpoint

https://app.march.tech/api/mcp

The server uses the Streamable HTTP transport and is fully stateless — each request is independent.

Authentication

Two methods are supported:

OAuth 2.1 (recommended)

Point your MCP client at the URL and it will handle authentication automatically via the browser. No API key needed.

API key

For non-interactive environments (CI/CD, scripts), use an API key from Settings > API Keys in the March web app.

Pass the key as a query parameter:

https://app.march.tech/api/mcp?token=march_your_api_key

Or as a header:

Authorization: Bearer march_your_api_key
