Firecrawl MCP Integration for Vercel AI SDK
Connect Firecrawl to Vercel AI SDK through the local KosmoKrator MCP gateway with scoped tools, credentials, and write policy.
Connect Firecrawl to Vercel AI SDK
Use KosmoKrator as a local integration gateway for Vercel AI SDK agents and scripts.
Create an MCP client that starts or connects to the KosmoKrator gateway for the selected integration. The gateway is local, scoped to this integration, and starts with
--write=deny so Vercel AI SDK can inspect read-capable tools without receiving write access by default.

kosmokrator mcp:serve --integration=firecrawl --write=deny Why Use KosmoKrator Here
Expose only Firecrawl instead of a broad multi-service tool list.
Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.
Start read-only, then opt into ask or allow for trusted workspaces.
