Intuition MCP Server
The Intuition MCP Server is an HTTP stream server designed to interact with the Intuition knowledge graph, enabling users to query and manage data through a set of powerful tools. It provides a robust API for extracting triples, searching for entities (atoms), retrieving account information, and exploring relationships such as followers and following. This README outlines the steps to get started, the available tools, their functionalities, and instructions for running a client using the Model Context Protocol (MCP) SDK.
This repository represents the evolution of our Intuition MCP Server, which we are pleased to be open sourcing for our ecosystem. This is built upon the foundation and testing we've done. There are several contributors who helped get to this point, including francoispqt, jonathanprozzi, and simonas-notcat.

Get Started
To run the Intuition MCP Server locally, follow these steps:
Clone the Repository: Clone the project repository to your local machine:
git clone <repository-url>
cd intuition-mcp-server
Install Dependencies: Install the required dependencies using pnpm:
pnpm install
Start the Server: Launch the server using the HTTP transport (recommended):
pnpm run start:http
This will start the Intuition MCP Server, making it available at the configured host and port (e.g., http://localhost:3001). Check the server configuration for the exact URL.
Verify the Server:
Once the server is running, you can test it by sending a request to the /mcp endpoint (for Streamable HTTP clients) or /sse endpoint (for legacy SSE clients). See the Running a Client (#running-a-client) section for details on connecting a client. We follow the most recent recommendations from the MCP SDK and recommend using the Streamable HTTP endpoint (/mcp) over SSE as it is in the process of being deprecated.
Note: Ensure you have pnpm installed globally (npm install -g pnpm) before running the above commands. If you encounter issues, verify that your Node.js version is 14 or higher.
Overview
The Intuition MCP Server is built to facilitate interactions with the Intuition knowledge graph, a decentralized data structure for storing and querying relationships between entities (atoms) such as accounts, concepts, and objects. The server operates as an HTTP stream server, leveraging the Model Context Protocol (MCP) to handle streaming requests and responses, making it ideal for real-time applications and large-scale data queries.
The server exposes a set of tools via API endpoints, each designed for specific tasks like extracting structured data (triples), searching for entities, retrieving account details, and exploring social connections (e.g., followers or recommendations). These tools are accessible using the MCP SDK, which supports both modern Streamable HTTP and legacy Server-Sent Events (SSE) transports for client-server communication. While we provide support for SSE, it is in the process of being deprecated in the MCP SDK, so we recommend using the Stremable HTTP endpoint.
Tools
The Intuition MCP Server provides the following tools, each with a specific purpose and input schema. All tools return responses sorted by relevance (e.g., position descending) and include detailed information, such as atom IDs and connections, to ensure comprehensive results.
Tools are registered and made available in the index.ts file.
extract_triples

Running a Client
The Intuition MCP Server uses the Model Context Protocol (MCP) SDK for client interactions, supporting both modern Streamable HTTP and legacy Server-Sent Events (SSE) transports. Below are the steps to set up and run a client to communicate with the server.
Prerequisites
Node.js (version 14 or higher).
MCP SDK: Install the @modelcontextprotocol/sdk package.
Access to the server URL (e.g., http://your-mcp-server:port/mcp).
Installation
Set up a project: Create a new project directory and initialize it with Node.js:
mkdir intuition-mcp-client
cd intuition-mcp-client
npm init -y
npm install @modelcontextprotocol/sdk
Install dependencies: The @modelcontextprotocol/sdk package includes the necessary modules for both Streamable HTTP and SSE transports.
Example Client Setup
Below is an example of a Node.js client using the MCP SDK to connect to the Intuition MCP Server and interact with its tools.
import { Client } from '@modelcontextprotocol/sdk/client/index.js';
import { StreamableHTTPClientTransport } from '@modelcontextprotocol/sdk/client/streamableHttp.js';
import { SSEClientTransport } from '@modelcontextprotocol/sdk/client/sse.js';
async function connectToMcpServer(url) {
let client;
const baseUrl = new URL(url);
try {
// Attempt to connect using Streamable HTTP transport
client = new Client({
name: 'streamable-http-client',
version: '1.0.0',
});
const transport = new StreamableHTTPClientTransport(baseUrl);
await client.connect(transport);
console.log('Connected using Streamable HTTP transport');
return client;
} catch (error) {
console.log(
'Streamable HTTP connection failed, falling back to SSE transport:',
error.message
);
// Fallback to SSE transport for legacy compatibility
client = new Client({
name: 'sse-client',
version: '1.0.0',
});
const sseTransport = new SSEClientTransport(baseUrl);
await client.connect(sseTransport);
console.log('Connected using SSE transport');
return client;
}
}
async function callMcpTool(client, toolName, payload) {
try {
// Send a request to the specified tool
const response = await client.callTool(toolName, payload);
// Handle streaming response
response.on('data', (data) => {
console.log('Received data:', data);
});
response.on('end', () => {
console.log('Stream ended');
});
} catch (error) {
console.error('Error calling MCP tool:', error.message);
}
}
// Example usage
async function main() {
const serverUrl = 'http://your-mcp-server'; // Replace with your server URL
const client = await connectToMcpServer(serverUrl);
// Example: Search for atoms related to Ethereum
await callMcpTool(client, 'search_atoms', { queries: ['ethereum', 'eth'] });
// Example: Extract triples
await callMcpTool(client, 'extract_triples', { input: 'Alice knows Bob' });
}
main().catch(console.error);
Making API Requests
Initialize the client:
Create an MCP Client instance and connect it to the server using either StreamableHTTPClientTransport or SSEClientTransport.
The client automatically handles transport negotiation and fallback to SSE if Streamable HTTP fails.
Construct the payload:
Use the input schema for the desired tool (e.g., {"queries": ["ethereum"]} for search_atoms).
Ensure the payload matches the tool’s JSON schema to avoid errors.
Send the request:
Use the client.callTool method to invoke a tool with the specified payload.
The client handles the underlying HTTP or SSE communication, including streaming responses.
Handle the response:
Responses are streamed and can be processed using event listeners (e.g., response.on('data', ...)).
Parse each chunk as JSON if the response is structured data.
Handle the end event to detect when the stream is complete.
Example Payloads:
For search_atoms:
await client.callTool('search_atoms', { queries: ['blockchain'] });
For get_account_info:
await client.callTool('get_account_info', {
identifier: '0x1234567890123456789012345678901234567890',
});
Notes
Server URL: Replace http://your-mcp-server with the actual server address.
Authentication: If the server requires an API key, configure it in the transport options (consult the MCP SDK documentation for details).
Error Handling: The client automatically retries with SSE transport if Streamable HTTP fails (e.g., due to a 4xx error).
Streaming: Ensure your application can handle streaming responses, as large datasets are returned incrementally.
Legacy Support: The server supports both Streamable HTTP and SSE transports for backwards compatibility with older clients.
Deployment
This repository contains a sample Dockerfile that you can use to deploy to services such as Render or any other host provider that supports Docker. The Dockerfile is already configured to work for deploying the project structure as is. If you make any changes to the repo structure after cloning you'll want to be sure to update this file.
We've included a render.yaml file for the public deployment. We invite you to create your own deployment. You can utilize our existing render.yaml file to deploy your own Render project.
