Does Codex support the Linear MCP server?

Yes. Codex connects to the Linear 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 Linear to Codex?

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

Which Linear tools can Codex use?

All 27 Linear tools your team allows, such as List Documents, Update Cycle, Update Project. Admins can narrow that list per team.

Can I control which teammates use Linear in Codex?

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

What if Codex doesn't show Linear tools?

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

```
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 Linear tools.

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

Metorial times out at startup: Codex waits 10 seconds by default. Raise startup_timeout_sec under [mcp_servers.metorial] in ~/.codex/config.toml.
