FereAI exposes a hosted MCP (Model Context Protocol) server, so you can drive on-chain research, swaps, and portfolio actions from Claude, ChatGPT, Cursor, Codex, Hermes, or Claude Code — wherever you already work.
One URL, Every Client. Point any MCP-aware client at https://api.fereai.xyz/mcp. Each provider handles OAuth its own way — usually a one-time browser sign-in linked to your Fere account. After that, the client can call Fere tools directly inside your conversations.

​
Pick Your Client

Claude (Desktop & Web)

Add Fere as a Connector, paste the URL, and finish OAuth in the browser.

Claude Code

Drop the JSON config snippet into your MCP servers config.

ChatGPT

Turn on Developer Mode in Apps, then add the URL as a custom MCP.

Hermes

Paste the URL directly into a Hermes chat — it installs the MCP and prompts for OAuth.

Cursor

Add the JSON snippet under mcpServers in Cursor’s MCP settings.

Codex

Use the Streamable HTTP MCP add flow and paste the URL.

​
Claude (Desktop & Web)

In Claude, open Settings → Connectors → Add custom connector and paste the URL below. Claude will pop up an OAuth window to link your Fere account; once you approve, every new conversation can call Fere tools. 
https://api.fereai.xyz/mcp

​
Claude Code

Add the following block to your Claude Code MCP config (typically ~/.claude.json or your project-level .mcp.json). On first use, Claude Code will open the OAuth flow in your browser. 
{
  "mcpServers": {
    "FereAI MCP": {
      "type": "http",
      "url": "https://api.fereai.xyz/mcp",
      "description": "FereAI MCP server for on-chain transactions."
    }
  }
}

​
ChatGPT

ChatGPT exposes custom MCPs behind a developer flag. Enable it once, then add the Fere URL as a new app.
1

Enable Developer Mode

Open Settings → Apps & Connectors and toggle Developer Mode on.
2

Add Custom MCP

Click Add custom MCP and paste https://api.fereai.xyz/mcp.
3

Complete OAuth

Complete the OAuth prompt to link your Fere account.

​
Hermes

Hermes makes this the simplest of all — just paste the URL into any chat: 
https://api.fereai.xyz/mcp
Hermes detects it as an MCP endpoint, installs the server, and walks you through OAuth inline. No config file needed.

​
Cursor

Open Settings → MCP in Cursor and add an entry under mcpServers. Cursor will run OAuth in your browser the first time you invoke a Fere tool. 
{
  "mcpServers": {
    "FereAI MCP": {
      "type": "http",
      "url": "https://api.fereai.xyz/mcp",
      "description": "FereAI MCP server for on-chain transactions."
    }
  }
}

​
Codex

In Codex, open the MCP settings and choose Add Streamable HTTP MCP. Paste https://api.fereai.xyz/mcp as the endpoint and approve the OAuth handshake when prompted.
OAuth Is Handled By Your Client. Fere never sees your client credentials. Each provider runs its own OAuth flow against your Fere account — the URL above is the only thing you ever paste. Revoke access anytime from your Fere account settings.
