OneScreen MCP Server
OneScreen's only API surface: a remote Model Context Protocol server over Streamable HTTP that exposes OOH audience personas, market and inventory rankings, geospatial points of interest, media-owner records and the plan/RFP/messaging marketplace workflow to any MCP-capable AI client. POST-only (GET returns 405); every call requires an OAuth 2.1 bearer token and the 401 advertises RFC 9728 protected-resource metadata, so a client can discover and register itself with no out-of-band configuration. The tool manifest (15 tools per the provider) is auth-gated.
