About
Statsig's own hosted MCP server connects your agent to your Statsig project. Ask which experiments are running and how they're doing, look up feature gates and dynamic configs, check metrics and audit logs, and create or update gates, experiments and configs without opening the console. Statsig documents it for ChatGPT, Claude Code, Cursor and Codex, and for any other client that supports Streamable HTTP. What you can do with it - List experiments and read their overall results, metric breakdowns, summary charts and version history - List feature gates, find stale ones, and read a gate's rules, results and history - Look up dynamic configs, metrics, metric sources and audit logs, and query Logs Explorer - Create and update gates, experiments and dynamic configs - Work with layers, segments, Parameter Stores, Autotunes, prompts and reviews - Clean up stale gates: find them in Statsig, then have your agent remove the checks from your code How it connects Statsig hosts it, so there's nothing to install. The install steps on this page use Statsig's V1 address, https://api.statsig.com/v1/mcp, and send your Statsig Console API key in a statsig-api-key header. You'll find your keys on the API keys page of the Statsig console (console.statsig.com/api_keys). Statsig now recommends its V3 server at https://api.statsig.com/v3/mcp, which signs you in with OAuth and groups the same operations into fewer tools. Its setup guides for Claude Code, Cursor, Codex and ChatGPT use that address. V1 remains supported. Good to know - A read-only key can use every read tool. Creating or changing anything needs a key with write permissions, and your project's permissions and review policies still apply. - On V3, updates and sensitive operations ask your agent for a confirmation, so review each change before it goes through. - OAuth sign-in only works with Personal Console API Keys, which your Statsig org owner has to enable for your role. - Statsig also runs a separate, public Docs MCP server that reads its documentation and needs no API key.
Once it’s added
“What experiments are currently running?”
“What gates are currently stale?”
“Find a stale gate and remove its checks from our codebase.”
“Show me the configuration for gate 'new-feature'.”
“Show me details about the experiment called 'new-checkout-flow'.”
“Create a new experiment called 'checkout-test'.”
Before you add it
Reads only
Experiments, their results and version history · Feature gates, dynamic configs and their rules · Metrics, metric sources, audit logs and Logs Explorer data
Makes changes · your agent can ask first
Creates and updates gates, experiments and dynamic configs · Creates layers, segments, Parameter Stores and Autotunes · Starts, approves and commits reviews
