Up Bank MCP

MCP setup

This page explains how to connect this deployed MCP server to ChatGPT or another remote MCP client.

Not an official app. This is a private Developer Mode connector, not a public app reviewed by OpenAI or Up Bank. Share it only with people who understand they are trusting this deployment with their own Up token.

Connect in ChatGPT

Use this URL when ChatGPT asks for the MCP server:

https://up.jacobwisniewski.dev/mcp

Open ChatGPT in a browser.
Open Settings, then Apps.
Open Advanced settings and enable Developer mode.
Return to Apps and select Create app.
Name it Up Bank or another clear name.
Choose Server URL, paste the MCP URL, and leave authentication as OAuth.
Accept the custom MCP server warning, connect the app, and complete the Up token authorization page.

First test: Use the Up Bank connector and run up_ping only.

Connect another MCP client

Use this URL for remote MCP clients that support Streamable HTTP and OAuth:

https://up.jacobwisniewski.dev/mcp

Open your MCP client's settings and add a new remote MCP server or custom connector.
Choose Streamable HTTP, remote MCP, or server URL if the client asks for a connection type.
Paste the MCP server URL above.
Choose OAuth authentication if the client asks. Most clients should discover the OAuth endpoints automatically.
Connect the server, complete the Up token authorization page, then test with up_ping.

This hosted deployment is OAuth-only. If your client cannot connect to authenticated remote MCP servers with OAuth, use a self-hosted local or private deployment instead.

OAuth values

Most clients only need the MCP server URL. Use these values only if your client asks for them.

MCP server URL: https://up.jacobwisniewski.dev/mcp
Transport: Streamable HTTP
Authentication: OAuth 2.1 authorization code with PKCE
Protected resource metadata: https://up.jacobwisniewski.dev/.well-known/oauth-protected-resource
Authorization server metadata: https://up.jacobwisniewski.dev/.well-known/oauth-authorization-server
Authorization URL: https://up.jacobwisniewski.dev/oauth/authorize
Token URL: https://up.jacobwisniewski.dev/oauth/token
Dynamic client registration: https://up.jacobwisniewski.dev/oauth/register

Up token authorization

Open the Up app on your phone.
Swipe right to the Up tab.
Open Data sharing.
Tap Personal Access Token.
Generate a token, choose its duration, and copy the token beginning with up:yeah:.
Paste it only into this server's authorization page, not into a ChatGPT message.

To revoke access later, disconnect the MCP app in your client and revoke or rotate the Up personal access token in the Up app under Data sharing.
