MCP Streamable HTTP
MCP Streamable HTTP endpoint (mcp-handler at /api/mcp). Auth: OAuth authorization_code (browser connectors), Authorization: Bearer, x-api-key, or last-resort ?api_key= (no anonymous, no session cookie). Tools: search_creators, list_campaigns, get_campaign, create_campaign, update_campaign, delete_campaign, generate_campaign_matches, add_campaign_match, remove_campaign_match, export_campaign, get_credits, list_api_keys, create_api_key, revoke_api_key. Agent access tokens cannot use list_api_keys, create_api_key, or revoke_api_key. Prefer auth.md for agent signup; path is protocol transport, not JSON CRUD API.
