BrainGraph MCP server for AI agents and assistants

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with BrainGraph MCP or direct API to ingest documents, search and retrieve graph nodes, summarize linked content, and create or update knowledge nodes through natural language.

TOOLS

Supported Tools

Every BrainGraph action and event your agent gets out of the box.

Get Document Progress

Get the current transcription, processing, and analysis status for a BrainGraph document.

Ingest Web Page

Fetch readable content from a public web page and queue it for BrainGraph ingestion.

Ingest YouTube Video

Submit a YouTube video for metadata, transcript, and speaker processing; the result may only confirm that processing was queued.

List Brains

List the connected BrainGraph account's knowledge brains and identify the default brain for filtering or targeting other tools.

List Documents

List BrainGraph documents newest first, optionally filtering by filename or notes, failed ingestion status, and brain.

List Graph Patterns

Find recurring relationship-chain patterns in the connected BrainGraph knowledge graph, subject to a minimum occurrence count.

Resolve Entity

Resolve an entity name to a canonical BrainGraph record.

Search Brain

Search facts in the connected account's BrainGraph knowledge graph using a natural-language question, optionally restricted to selected brains.

Transcribe Audio

Upload an audio file or submit a direct public audio URL for diarized transcription and graph ingestion.

Upload Document

Upload a document file supplied by the caller or plain text and queue it for BrainGraph ingestion.

SETUP GUIDE

Connect BrainGraph MCP Tool with your Agent

1

Install Composio

typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai
Install the Composio SDK and your agent framework
2

Create a session with MCP enabled

typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["brain_graph"],
  mcp: true,
});
Create a session scoped to BrainGraph and read its MCP URL and headers
3

Connect your agent to the MCP server

typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";

const client = await createMCPClient({
  transport: { type: "http", url: mcp.url, headers: mcp.headers },
});

const { text } = await generateText({
  model: openai("gpt-5.6-sol"),
  tools: await client.tools(),
  prompt: "Search the knowledge graph for 'onboarding process' and summarize key steps",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();
Pass the session's MCP URL and headers to your agent and run a BrainGraph request
SETUP GUIDE

Connect BrainGraph API Tool with your Agent

1

Install Composio

typescript
npm install @composio/core @composio/openai openai
Install the Composio SDK, the OpenAI provider, and the OpenAI SDK
2

Create a Composio session

typescript
import OpenAI from "openai";
import { Composio } from "@composio/core";
import { OpenAIResponsesProvider } from "@composio/openai";

const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();

const session = await composio.create("your-user-id", { toolkits: ["brain_graph"] });
const tools = await session.tools();
Initialize Composio with the OpenAI Responses provider and create a session scoped to BrainGraph
3

Run BrainGraph tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Search the knowledge graph for 'onboarding process' and summarize key steps" }],
});

while (response.output.some((o) => o.type === "function_call")) {
  const outputs = await composio.provider.handleToolCalls(session, response.output);
  response = await client.responses.create({
    model: "gpt-5.6-sol",
    tools,
    previous_response_id: response.id,
    input: outputs,
  });
}

console.log(response.output_text);
Send a request, execute the BrainGraph tool calls through the session, and print the final answer

Why Use Composio?

AI Native BrainGraph Integration

  • Supports both BrainGraph MCP and direct API based integrations

FAQ

Frequently asked questions

Yes, BrainGraph requires you to configure your own API key credentials. Once set up, Composio handles secure credential storage and API request handling for you.

Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.

Yes. Composio is SOC 2 Type II compliant and is built to keep your BrainGraph connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.

Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.

Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.

Create the key in your BrainGraph account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the BrainGraph actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside BrainGraph at any time.

When you connect a BrainGraph account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in BrainGraph as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.

Whatever the credentials you connect allow inside BrainGraph. If BrainGraph lets you scope a key to specific permissions, create a scoped one so the agent can only do what you intend. You can revoke the key inside BrainGraph at any time.

Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each BrainGraph connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.

The connection stops working the moment BrainGraph rejects the old key. Create a new key in BrainGraph and reconnect the account from the Composio dashboard or by asking your agent to reconnect BrainGraph. Nothing else changes.

Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal BrainGraph use. Paid plans add higher limits and team features. Your BrainGraph plan and its API limits still apply as usual.

Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple BrainGraph accounts).

With Composio, you connect BrainGraph once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
