Api Key

BrainGraph builds a searchable knowledge graph from documents, recordings, web pages, and other source material. It provides structured, grounded knowledge to improve AI reasoning and retrieval.

10 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your BrainGraph account to Claude via Composio Connect, enabling it to search graph for onboarding process docs, summarize meeting recordings from last week, find citations for product architecture decisions, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

4. Connect your BrainGraph account

Back in Claude, ask it to connect to BrainGraph or give it any BrainGraph-related task.

For example, ask Claude to:

  • "Search graph for onboarding process docs"
  • "Summarize meeting recordings from last week"
  • "Find citations for product architecture decisions"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your BrainGraph account is ready to use.

What is the BrainGraph Claude Connector, and what's possible with it?

The BrainGraph MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your BrainGraph account. It provides structured and secure access so your agent can perform BrainGraph operations on your behalf.

Troubleshooting

1. Why does Claude not use the Composio connector for BrainGraph?

The connector can show as connected, but Claude must use it in each BrainGraph conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to BrainGraph again.

2. Why does Claude show an MCP server error before BrainGraph connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for BrainGraph.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect BrainGraph.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the BrainGraph authorization link not work?

The Composio connector is one server. Your BrainGraph account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the BrainGraph connection.
  • Composio creates a fresh BrainGraph authorization link.
  • Open that link in your browser and finish the BrainGraph sign-in.

4. Why do BrainGraph actions fail after they worked before?

The BrainGraph connection can expire or lose permission.

  • Ask Claude to inspect the BrainGraph connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the BrainGraph account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in BrainGraph.
  • If the action still fails with a permission error, check that the connected account has that permission in BrainGraph itself.

5. How do I switch to a different BrainGraph account?

Claude can manage the BrainGraph connection for you.

  • Ask Claude to disconnect or delete the current BrainGraph account.
  • Ask Claude to connect BrainGraph again.
  • Open the new Composio authorization link for BrainGraph.
  • Sign in with the other BrainGraph account in the browser.
  • After the account connects, ask Claude to retry the BrainGraph task.

6. Why is my BrainGraph connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your BrainGraph connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If BrainGraph tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect BrainGraph.

FAQ

Frequently asked questions

With a standalone BrainGraph MCP server, the agents and LLMs can only access a fixed set of BrainGraph tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from BrainGraph and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right BrainGraph tools.

Yes, absolutely. You can configure which BrainGraph scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your BrainGraph data and credentials are handled as safely as possible.
