Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 870+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.
How to install Salesforce service cloud MCP in Codex
Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(Optional) Authenticate with OAuth
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
Verify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
Codex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on connect.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- Restart and verify if it's there in
.codex/config.toml
What is the Salesforce service cloud MCP server, and what's possible with it?
The Salesforce service cloud MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Salesforce Service Cloud account. It provides structured and secure access to your customer service data, so your agent can perform actions like managing cases, retrieving knowledge articles, automating service processes, and tracking customer interactions on your behalf.
- Case management and triage: Empower your agent to create, update, assign, or close customer service cases, ensuring timely resolution of inquiries and incidents.
- Knowledge base retrieval: Let your agent search, read, and recommend relevant knowledge articles to assist with customer support and internal troubleshooting.
- Customer interaction tracking: Have your agent log new interactions, fetch historical communication, and surface recent touchpoints for a full view of customer engagement.
- Omnichannel support automation: Enable your agent to route cases, escalate issues, and manage service requests across chat, email, phone, and social channels all from one place.
- Service workflow automation: Direct your agent to trigger macros, update case statuses, or launch automated actions to streamline repetitive tasks and boost support team productivity.

FAQ
What are the differences in Tool Router MCP and Salesforce service cloud MCP?
With a standalone Salesforce service cloud MCP server, the agents and LLMs can only access a fixed set of Salesforce service cloud tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Salesforce service cloud and many other apps based on the task at hand, all through a single MCP endpoint.
Can I use Tool Router MCP with Codex?
Yes, you can. Codex 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 Salesforce service cloud tools.
Can I manage the permissions and scopes for Salesforce service cloud while using Tool Router?
Yes, absolutely. You can configure which Salesforce service cloud 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.
How safe is my data with Composio Tool Router?
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 Salesforce service cloud data and credentials are handled as safely as possible.
