Squidbrake now reaches agents beyond local coding tools.

Agents that connect to MCP by URL (ChatGPT and claude.ai connectors, Devin, n8n, cloud agents)

squidbrake proxy --app github --serve 0.0.0.0:9000 --token "$PROXY_TOKEN" -- npx -y @modelcontextprotocol/server-github
  • The agent adds https://your-host:9000/mcp and sends the token (Bearer, X-Squidbrake-Token or ?token=). Without it, nothing gets in.
  • Each conversation is checked on its own, so chains never mix. A caller can name its conversation with X-Squidbrake-Session.

Remote MCP servers that need their own auth

  • squidbrake proxy --url ... --header 'Authorization: Bearer ${TOKEN}'.
  • connect guard now guards these servers too, instead of skipping them.

Cursor and Codex

  • Cursor: file edits and deletes (preToolUse, recent Cursor) and MCP tools (beforeMCPExecution) are now checked, on top of terminal commands and reads.
  • Codex: MCP tools are now checked.
  • Run squidbrake connect all again to pick these up.

Agent frameworks

  • gw.guard_tools([...]) puts all of an agent's tools behind Squidbrake in one line: OpenAI Agents SDK, LangChain / LangGraph, CrewAI, PydanticAI, smolagents and Google ADK.
  • A call Squidbrake stops doesn't run, and the model reads a "NOT RUN: ..." message instead of the run crashing.
  • Tested against langchain-core 1.6.7 and openai-agents 0.23.1.

Fix

  • The Python client works when an app runs more than one event loop (several asyncio.run calls).
