Connect Muse to Google BigQuery MCP. Run yesterday's sales summary query, find top 10 customers by revenue, and more using natural language, with authentication handled for you.
Google BigQuery is a fully managed cloud data warehouse for fast SQL analytics on massive datasets. It's designed to help you analyze big data with ease, speed, and built-in machine learning.
Muse is Meta's AI assistant. It can connect to outside tools through custom connectors, which use the Model Context Protocol (MCP).
This guide explains how to connect Google BigQuery to Muse using Composio Connect, which handles OAuth, token refresh, and reliability so you do not have to. You add Composio as a custom connector once, then ask Muse to work with Google BigQuery in plain language.
You add Composio to Muse once as a custom connector, then connect Google BigQuery from the chat.
Start a new Muse chat and send this message. Muse builds the connector and shows a button to add your API key.
Create a Custom Connector for the Composio remote MCP server and connect to it:
- Name: Composio
- Transport: remote streamable HTTP
- URL: https://connect.composio.dev/mcp
- Auth: API key sent in the x-consumer-api-key header
Open the secure credentials store so I can enter the API key there, not in this chat. Then list its tools to confirm the connection works.Open the Muse page in your Composio dashboard and copy your API key. It starts with ck_.
Don't paste it into the chat. It goes in Muse's secure credentials store in the next step.
Tap the button Muse shows to open Add custom connector, paste your API key, then tap Add. Muse lists the Composio tools once it connects.
Back in the chat, ask Muse to connect to Google BigQuery or give it any Google BigQuery task.
For example, ask it to:
It will prompt you to authenticate and authorize access.
That's it. Composio's tools are now available in Muse, and your Google BigQuery account is ready to use.
The Google BigQuery MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Google BigQuery account. It provides structured and secure access to your projects, datasets, tables, jobs, routines, and machine learning models, so your agent can organize data, inspect schemas, load records, run query jobs, and retrieve results on your behalf.
Now that Google BigQuery is connected, extend your setup by connecting the other apps you already use every day, so Muse can run true cross-app workflows end to end.
Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single connection, Muse can coordinate multiple tools safely and reliably in one conversation.
Muse shows the button only when you ask it to open the secure credentials store.
The key or the connector settings are not correct.
ck_.https://connect.composio.dev/mcp and the header is x-consumer-api-key.Muse may not pick the Composio connector for the request.
Your Google BigQuery connection expired or was removed.
Treat the key as exposed.
Every Google BigQuery action and event your agent gets out of the box.
