Connect through MCP

Model Context Protocol (MCP) lets a compatible AI client use Beacon tools for a signed-in user.

Use this hosted endpoint:

https://postwithbeacon.com/mcp

Use the exact address, including /mcp. Do not add an agent key to the MCP configuration.

Hosted MCP is available on every active Beacon plan, including Free. Your plan's post limits and AI credits still apply. Publishing to X through MCP requires Starter or a higher plan.
