Nothing serious here today

Today is the operative word: we check AVEL every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add avel -- uvx agent-interchange

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "avel": {
      "args": [
        "agent-interchange"
      ],
      "command": "uvx"
    }
  }
}

~/.codex/config.toml

[mcp_servers.avel]
command = "uvx"
args = ["agent-interchange"]

.cursor/mcp.json

{
  "mcpServers": {
    "avel": {
      "args": [
        "agent-interchange"
      ],
      "command": "uvx"
    }
  }

      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: AVEL_BASE_URL (Base URL of the AVEL instance to verify against (default: https://aisrail.fly.dev)), AVEL_PRIVATE_KEY (EVM private key of the agent identity this MCP server represents — signs every verify()/issue_challenge()/verify_challenge()/get_verdict() call. Never exposed as a tool argument.). The author declared them in the registry entry; get the values from the project itself.

AVEL — questions

Answers built from our own checks of this server.

Why is there no uptime for AVEL?

AVEL runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package agent-interchange.

How do I connect AVEL?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls agent-interchange straight from pypi; nothing to host, nothing to sign up for.

Is AVEL open source?

Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
