AgentRescue MCP

AgentRescue provides diagnostics for AI agents by analyzing sanitized HTTP, API, and MCP errors to return safe, structured recovery guidance. It operates as a read-only advisory service that helps agents determine next steps after failures without executing fixes or handling credentials.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Use diagnose_failure after an HTTP, API, or MCP request fails, or when transport succeeds but the expected result is missing or incorrect. Provide only sanitized error text from the latest request and the matching system. Results are advisory, rule-based, and never run fixes. Review evidence before acting; high-risk changes require human approval. Never send credentials or personal data.

diagnose_failure

Advertised by the server during the last successful anonymous check.

Use after an HTTP, API, or MCP request fails, or when transport succeeds but the expected result is missing or incorrect. Send only the sanitized error from the latest request and its system. Returns advisory, evidence-linked recovery steps; never executes fixes. Never include credentials or personal data. No charge; the x402 paid trial is disabled.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http agentrescue-mcp https://agentrescue-mcp.onrender.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add agentrescue-mcp --url https://agentrescue-mcp.onrender.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable agentrescue-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "agentrescue-mcp": {
      "url": "https://agentrescue-mcp.onrender.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "agentrescue-mcp": {
      "type": "streamableHttp",
      "url": "https://agentrescue-mcp.onrender.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start agentrescue-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "agentrescue-mcp": {
      "type": "http",
      "url": "https://agentrescue-mcp.onrender.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http agentrescue-mcp https://agentrescue-mcp.onrender.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "agentrescue-mcp": {
      "url": "https://agentrescue-mcp.onrender.com/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "agentrescue-mcp": {
      "serverUrl": "https://agentrescue-mcp.onrender.com/mcp"
    }
  }
}
