Mistral Le Chat

# Add as a custom MCP connector.

Le Chat connects to remote MCP servers and detects OAuth sign-in on its own, so there’s no key to copy. Mistral says the account owner is the admin on Free, Pro and Student plans; on Team and Enterprise an admin may need to add it.

Step 01

## Add the connector, then sign in.

Le Chat Connectors

```
1. Le Chat → Connectors → + Add Connector → Custom MCP Connector
2. Name: BankBridge
3. Server URL: https://bankbridge.money/api/mcp
4. Click Connect. OAuth is detected automatically: sign in to BankBridge, click Allow.

(No token needed. OAuth handles it.)
```

Step 02

## Verify it works.

Start a chat with the connector enabled and ask:

try this

```
list my accounts and balances
```

Troubleshooting

Client connects but shows 0 tools.

Usually the client is caching an old config, or you're on a mode that doesn't expose tools (Ask/Edit vs Agent, for example).

**Fix:** Fully quit + relaunch the host app. In VS Code Copilot, switch to Agent mode.

401 Unauthorized on every call.

The API key is missing, typo'd, or got revoked. Check the Authorization header starts with \`Bearer \` (note the space) and ends in a key you still own.

**Fix:** Paste a fresh key from [Settings](https://bankbridge.money/dashboard/settings).
