Does Codex support the Freeagent MCP server?

Yes. Codex connects to the Freeagent MCP server through one CLI command, pointed at your Metorial URL. You need the Codex CLI, IDE extension or ChatGPT desktop app.

Do I need an API key to connect Freeagent to Codex?

No. You sign in to Freeagent once through Metorial, and Codex uses that connection. No API keys go into Codex's settings.

Which Freeagent tools can Codex use?

All 40 Freeagent tools your team allows, such as List Users, Create Timeslip, List Bank Accounts. Admins can narrow that list per team.

Can I control which teammates use Freeagent in Codex?

Yes. Role-based access control decides who can use Freeagent and which of its tools appear in Codex, and every call is logged with the person's identity.

What if Codex doesn't show Freeagent tools?

Codex can connect without credentials and then see nothing. Run codex mcp login metorial to complete the OAuth sign-in.

2. Add the server and sign in
The Codex CLI, IDE extension and ChatGPT desktop app share this config.
```
codex mcp add metorial --url <your-magic-mcp-url>
codex mcp login metorial
```
3. Check the connection
Type /mcp in Codex to see Metorial and its Freeagent tools.

Once Freeagent is enabled in Metorial, teammates sign in with SSO and get the same connection in Codex, with only the tools their role allows.
