MCP Architecture with Agentforce

!alt text

Agentforce MCP Server

This is an MCP (Model Context Protocol) server for Salesforce's Agentforce Service Agent. THe MCP Server uses Agentforce Agent API to communicate with the Agent while exposing the main API interfaces as Tools based on the MCP Protocol.

🧩 MCP Tools Exposed

Tool Name	Description
start-session	Initializes a new Agentforce chat session
send-message	Sends a message to the active session
end-session	Ends the active session

🛠️ Requirements

• Node.js 18+
• Salesforce Org with Agentforce and an active Agentforce Service Agent
• Connected App with Client Credentials OAuth2 flow
• MCP-compatible client (e.g. ChatGPT, Open Interpreter, or custom)

📦 Installation

npm install

Or if you're setting up from scratch:

npm install @modelcontextprotocol/sdk axios zod

🔧 Build

npm run build

🔍 Testing

Use an MCP-compatible client (like MCP Inspector) to call tools and verify responses https://modelcontextprotocol.io/docs/tools/inspector.

• Run the command below

  npx @modelcontextprotocol/inspector node ./build/server.js \
       <SALESFORCE_ORG_DOMAIN_URL > \
       <CONNECTEDAPP_CLIENTID> \
       <CONNECTEDAPP_CLIENTSECRET> \
       <AGENTID>
  
  

• Navigate to the inspector at http://localhost:5173/ and test your MCP Server
• More info to test MCP Server https://modelcontextprotocol.io/docs/tools/debugging
• More info on setting up and using Agentforce Agent API https://developer.salesforce.com/docs/einstein/genai/guide/agent-api-get-started.html

🛡️ Error Handling

All errors are standardized using a centralized error handler. If something goes wrong (e.g., authentication failure), meaningful messages will be shown.

Claude Desktop Config

The following uses stdio so the mcp server is running locally.

{
  "mcpServers": {
    "agentforce" : {
            "command": "node",
            "args": [
                "/path/to/directory/build/server.js",
                "SALESFORCE_ORG_DOMAIN_URL",
                "CONNECTEDAPP_CLIENT_ID",
                "CONNECTEDAPP_CLIENT_SECRET",
                "AGENT_ID"
            ]
        }
  }
}

##💡 Notes

This server uses STDIO transport. If you want to use SSEServerTransport use the sample below

import { SSEServerTransport } from "@modelcontextprotocol/sdk/server/sse.js";
import express from "express";

const app = express();
var transport: SSEServerTransport ;

app.get("/sse", async (req, res) => {
  transport = new SSEServerTransport("/messages", res);
  await server.connect(transport);
});

app.post("/messages", async (req, res) => {
  // Note: to support multiple simultaneous connections, these messages will
  // need to be routed to a specific matching transport. (This logic isn't
  // implemented here, for simplicity.)
  await transport.handlePostMessage(req, res);
});

app.listen(PORT);
