Common questions
Is AgentRescue safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 15 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

AgentRescue
AgentRescue helps AI agents diagnose HTTP, API, and MCP failures. It returns bounded, structured recovery guidance and never executes fixes.
Live service
- MCP:
https://agentrescue-mcp.onrender.com/mcp(Streamable HTTP) - HTTP diagnosis:
POST https://agentrescue-mcp.onrender.com/v1/diagnose - Developer setup:
https://agentrescue-mcp.onrender.com/developers - Pricing and current payment status:
https://agentrescue-mcp.onrender.com/pricing - OpenAPI:
https://agentrescue-mcp.onrender.com/openapi.json - Agent instructions:
https://agentrescue-mcp.onrender.com/llms.txt
The live service runs agentrescue/paid_trial_app.py. Diagnosis is currently free because x402 payments are disabled. The public registry listing is AgentRescue 0.2.0. No customer demand or production revenue has been verified.
Send only synthetic or sanitized error excerpts; secret redaction is best-effort. Recovery guidance is advisory, confidence is qualitative and uncalibrated, and high-risk steps require human review.
Run locally
Requires Python 3.12+. Install the pinned dependencies from agentrescue/requirements.txt and agentrescue/requirements.lock, then start the hosted entry point from agentrescue/ with python -m uvicorn paid_trial_app:app --host 127.0.0.1 --port 8000. For the minimal standard-library prototype, run python3 app.py from agentrescue/.
Run checks from agentrescue/ with .venv/bin/python -m compileall -q . and .venv/bin/python -m unittest -q.
Payments
The proposed price is $0.01 USDC per successful diagnosis when the service owner explicitly enables x402. Production payments are disabled. Never put wallet private keys or facilitator credentials in Render or this repository. Production activation requires an owner-provided receiving address, a selected HTTPS facilitator, and explicit review and approval of the live configuration.
