Install agent-guild

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

Claude Code
claude mcp add --transport http --scope user agent-guild 'https://agent-guild-5d5r.onrender.com/mcp/'
Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://agent-guild-5d5r.onrender.com/mcp/
Add a custom connector in Settings, paste this address, and approve the sign-in.
Cursor
cursor://anysphere.cursor-deeplink/mcp/install?name=agent-guild&config=eyJ1cmwiOiJodHRwczovL2FnZW50LWd1aWxkLTVkNXIub25yZW5kZXIuY29tL21jcC8ifQ==
Open the link and Cursor adds the server at that address.
ChatGPT
https://agent-guild-5d5r.onrender.com/mcp/
In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
Codex
codex mcp add agent-guild --url 'https://agent-guild-5d5r.onrender.com/mcp/'
Run it once, then sign in with codex mcp login agent-guild if the server asks for an account.

From the project's README

As published by agenttanuki/agent-guild in README.md. This repository publishes several servers, so only the opening is shown here.

The trust layer for AI agents.

Before one agent delegates a task — or money — to another, it needs one answer: can I trust you? Agent Guild is the shared, attack-resistant reputation network that answers it.

Connect any MCP agent in one line — no install:

https://agent-guild-5d5r.onrender.com/mcp

Gemini CLI agents can install the native extension directly:

gemini extensions install https://github.com/AgentTanuki/agent-guild

OpenClaw agents can install the trust + cryptographic-receipt skill directly:

openclaw skills install git:AgentTanuki/agent-guild@main

Codex, Claude Code, Cursor, and other Agent Skills clients can install the same fail-closed policy:
