How to integrate Workiom MCP with Codex
Connect Codex to Workiom MCP. List all active projects in our workspace, create a new client record in crm list, and more using natural language, with authentication handled for you.
Api Key
Workiom is a workflow automation platform that lets businesses design custom processes and integrate apps. It streamlines operations to reduce manual work and boost productivity.

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 1000+ 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 Workiom 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.
bash
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
bash
codex mcp listCodex 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 dashboard.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
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }What is the Workiom MCP server, and what's possible with it?
The Workiom MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Workiom account. It provides structured and secure access to your Workiom workspace, so your agent can perform actions like listing your databases, creating new workflow records, and retrieving business data automatically.
- List and explore Workiom databases: Instantly fetch and review all lists in your workspace, making it easy to discover and reference your business data structures.
- Automate record creation: Direct your agent to add new records to any list, capturing details like text, numbers, dates, and static fields for streamlined workflows and reduced manual entry.
- Retrieve and filter records: Effortlessly pull relevant records from specific lists, with support for filtering, sorting, and pagination to quickly surface the data you need.
- Workspace structure insights: Get field definitions and metadata for lists, so your agent can understand data models and populate records accurately.
Conclusion
You've successfully integrated Workiom with Codex using Composio's MCP server. Now you can interact with Workiom directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
- Seamless integration across CLI, VS Code, and standalone app
- Natural language commands for Workiom operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Workiom operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

FAQ
Frequently asked questions
With a standalone Workiom MCP server, the agents and LLMs can only access a fixed set of Workiom tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Workiom and many other apps based on the task at hand, all through a single MCP endpoint.
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 Workiom tools.
Yes, absolutely. You can configure which Workiom 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.
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 Workiom data and credentials are handled as safely as possible.
