Salesforce MCP Sample Integration
This project provides a basic example of integrating with Salesforce using the Model Context Protocol (MCP). It allows interaction with Salesforce features like sending emails and deploying Apex code through MCP tools.
Prerequisites
- Node.js and npm (or yarn) installed.
- A Salesforce org where you can create a Connected App.
Setup
-
Install Dependencies:
npm install # or yarn install
-
Configure Salesforce Credentials:
- You MUST create a
credentials.js
file inside autils
folder (./utils/credentials.js
). - This file needs to export a function
getSalesforceCredentials()
which returns your Salesforce connection details necessary for JWT Bearer Flow authentication. - Important: Ensure you have a Connected App configured in Salesforce for JWT authentication, allowing the appropriate scopes and pre-authorizing the relevant user profile.
utils/credentials.js
Example:import fs from 'fs'; import path from 'path'; // You might load these from environment variables, a config file, etc. export function getSalesforceCredentials() { // --- IMPLEMENT YOUR LOGIC HERE to securely load credentials --- const loginUrl = "YOUR_SALESFORCE_LOGIN_URL"; // e.g., https://login.salesforce.com or https://yourdomain.my.salesforce.com const username = "YOUR_SALESFORCE_USERNAME"; const clientId = "YOUR_CONNECTED_APP_CONSUMER_KEY"; // Load your private key used to sign the JWT assertion // Ensure the key is formatted correctly, including BEGIN/END lines. const privateKey = fs.readFileSync(path.resolve(__dirname, 'path/to/your/server.key'), 'utf8'); // Example: const privateKey = process.env.SF_PRIVATE_KEY; if (!loginUrl || !username || !clientId || !privateKey) { throw new Error("Missing required Salesforce credentials in utils/credentials.js"); } return { loginUrl, username, clientId, privateKey }; }

I have been using the mcp-salesforce-example by lciesielski, and it's an exemplary project for anyone working with Salesforce integration. It offers clear, concise examples, making it an excellent resource for both beginners and experienced developers. The repository is well-maintained, with comprehensive documentation that simplifies the implementation process. Highly recommended!
