Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Codacy MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

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 Codacy 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 Codacy MCP server, and what's possible with it?
The Codacy MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Codacy account. It provides structured and secure access to your code quality dashboard, so your agent can perform actions like listing projects, managing API tokens, checking organization repositories, and retrieving user account details on your behalf.
- Automated project listing and discovery: Instantly fetch a comprehensive list of all projects accessible to your Codacy account for quick overview and navigation.
- Organization and repository management: Ask your agent to enumerate all organizations you belong to and drill into the repositories associated with each, helping you keep track of where your code lives.
- API token lifecycle management: Effortlessly create or delete API tokens as needed, making it easy to manage secure integrations and access controls without leaving your flow.
- User account insights and verification: Retrieve account details to confirm authentication, audit user info, or set up new integrations with confidence.
