Overview

You can set up the Statsig MCP server using an API key on Codex CLI and Codex IDE Extension today.

​
Installation

To setup Statsig MCP with Codex, add the below to your ~/.codex/config.toml file: 
[mcp_servers.statsig]
command = "npx"
args = ["--yes", "mcp-remote", "https://api.statsig.com/v1/mcp", "--header", "statsig-api-key: console-YOUR-CONSOLE-API-KEY"]
trust_level = "trusted"
Replace console-YOUR-CONSOLE-API-KEY with your actual Statsig Console API key, which you can retrieve here. Ensure your API key has the right permissions — read-only keys can view data, while write keys can make changes to your project!

​
Using Statsig MCP with Codex

With Statsig MCP configured in any Codex environment, you can:
  • Explore Experiments: “List all my active experiments”
  • Manage Gates: “What gates are currently stale?”
  • Configure Dynamic Configs: “Show me the configuration for the dynamic config ‘dynamic-config’”
  • Get Insights: “Show me details about the experiment called ‘new-checkout-flow‘“

​
Next Steps

After installation, you can:
  • List experiments, gates, and dynamic configs
  • Create and update experiments, gates, and configs
  • Access your Statsig data directly from Codex
