# config.toml: OAuth storage

mcp_oauth_credentials_store

Select where Codex stores MCP OAuth credentials.

mcp_oauth_credentials_store = "file"

Behavior

"file" persists tokens to disk so future MCP logins reuse them.

Sharing

If multiple MCP servers should share credentials on the same machine, use the file-backed store. Distribute the file via your standard secrets workflow.
