Codex CLI

One command.

codex mcp add registers BankBridge and opens the sign-in in your browser. No config file editing, no key to paste.

Step 01

Run one command.

terminal, one line

codex mcp add bankbridge --url https://bankbridge.money/api/mcp
# Codex opens the BankBridge sign-in in your browser.
# Later, to sign in again: codex mcp login bankbridge

or edit ~/.codex/config.toml

# Older Codex builds only: add once at top level
# experimental_use_rmcp_client = true

[mcp_servers.bankbridge]
url = "https://bankbridge.money/api/mcp"
bearer_token_env_var = "BANKBRIDGE_API_KEY"

# Then in your shell:
# export BANKBRIDGE_API_KEY="bbk_your_api_key_here"

Restart Codex CLI after editing the config.

Codex opens the BankBridge sign-in page; sign in and click Allow. Signed in here? The command above uses your API key from your dashboard instead: put the export line in your ~/.zshrc or ~/.bashrc so it persists.

Step 02

Verify it works.

Start Codex, then in any session:

try this

how much did I spend this week?

Run /mcp to see the BankBridge tools. Zero tools on an older Codex build? Add experimental_use_rmcp_client = true at the top level of config.toml, above any [section], or update Codex.

Cloud-hosted Codex?

For OpenAI’s cloud Codex (the GitHub-connected one), add BankBridge via the per-environment MCP settings instead. See the Codex Cloud guide.
