Msty Studio

Add one tool in the Toolbox.

Msty Studio adds remote MCP servers from the Toolbox. Paste the URL and your key, and the Tool Console lists what it found.

Read-only. Your agent can see balances and transactions, and nothing can move money, pay a bill, or place a trade. BankBridge doesn’t store your transactions. How it’s secured · Try it with sample data first

Step 01

Add the tool.

Msty Studio

1. Toolbox → Add New Tool
2. Name: BankBridge
3. Connection type: HTTP
4. MCP server URL: https://bankbridge.money/api/mcp
5. Authentication: Bearer Token
6. Bearer token: bbk_your_api_key_here
7. Save

Saving also creates a toolset named BankBridge, unless you turn off Create a toolset for this tool.

Step 02

Verify it works.

Go to Toolsets, open BankBridge, and click the {*} control next to the tool. In the Tool Console, click List BankBridge’s Features. You should see list_accounts and the rest. Enable the toolset in a conversation and ask:

try this

list my bank accounts and balances

To test the config before you sign up, use the key bbk_demo. It returns sample data.

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.

Tools return a NO_CONNECTIONS warning.

You haven't linked a bank yet.

Fix: Visit Connect a bank . The bank-connect flow opens automatically, ~30 seconds.
