NewDevelopers & MCP

Laguna Beach plugin and new MCP requirements tools

The public Laguna Beach plugin is now generated from CrossBeam's current city rules, with the City's checklists, plan-set kinds and fee math, and is checked for drift. The MCP server adds tools to fetch a permit-drawings skill and a city's review requirements, and drawings can be handed to a city plugin to fill forms.

NewDevelopers & MCP

Ask AI available to agents over MCP

Connected agents can now ask CrossBeam's Ask AI through the MCP server, using the same engine and tools as the web chat, and follow up by conversation ID without resending the transcript. Each request runs with the signed-in user's own permissions, and long web conversations now keep every turn in history.

MCP connections stay signed in after protocol upgrade

The MCP server's sign-in layer moves to the newer authorization standard while existing connections keep working, and AI clients can now register by publishing a client metadata document instead of a manual registration step.
