## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Statsig.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Statsig account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## Also integrate Statsig with

- [ChatGPT](https://composio.dev/toolkits/statsig/framework/chatgpt)
- [Claude Cowork](https://composio.dev/toolkits/statsig/framework/claude-cowork)
- [Hermes](https://composio.dev/toolkits/statsig/framework/hermes-agent)

## TL;DR

### How Atomic Agent connects to Statsig
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect Statsig to Atomic Agent

### Connect Statsig to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in Statsig. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Statsig account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## What is the Statsig MCP server, and what's possible with it?

The Statsig MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Statsig account. It provides structured and secure access so your agent can perform Statsig operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `STATSIG_CHECK_GATE` | Check Feature Gate | Evaluate one Statsig feature gate with optional user context without logging an exposure. A false result can mean either that the context fails the gate or that the gate name does not exist. |
| `STATSIG_CHECK_GATES` | Check Feature Gates | Evaluate multiple Statsig feature gates with optional shared user context without logging exposures. Results are keyed by gate name; a false result does not prove that a gate exists. |
| `STATSIG_GET_DYNAMIC_CONFIG` | Get Dynamic Config | Evaluate a Statsig dynamic config or experiment with optional user context and return its value and assignment metadata without logging an exposure. A missing name returns an empty value object. |
| `STATSIG_GET_LAYER` | Get Layer | Evaluate a Statsig layer with optional user context and return its parameter values and assignment metadata without logging an exposure. A missing layer is reported as not found. |
| `STATSIG_GET_RANKED_VARIANTS` | Get Ranked Variants | Rank variants for a Statsig contextual-bandit Autotune configuration using optional user context without logging an exposure. |
| `STATSIG_LOG_CUSTOM_EXPOSURES` | Log Custom Exposures | Permanently log one or more Statsig gate, experiment, or dynamic-config exposures when automatic exposure logging is not being used. Acknowledged exposures cannot be deleted through the runtime API. |
| `STATSIG_LOG_EVENTS` | Log Events | Permanently log one or more custom Statsig events for analytics and metric calculation in a single batch. Acknowledged events cannot be deleted through the runtime API. |

## Supported Triggers

None listed.

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Conclusion

### Use Statsig from Atomic Agent
With your account connected, ask Atomic Agent to work with Statsig in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Statsig MCP?

With a standalone Statsig MCP server, the agents and LLMs can only access a fixed set of Statsig tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Statsig and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent 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 Statsig tools.

### Can I manage the permissions and scopes for Statsig while using Tool Router?

Yes, absolutely. You can configure which Statsig 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 Statsig data and credentials are handled as safely as possible.
