## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Statsig MCP or direct API to evaluate feature gates, update dynamic configs, run experiments, and query event metrics through natural language.

## Summary

Statsig is a server-side platform for feature gate evaluation, dynamic configuration, experimentation, and event measurement.
It helps teams safely roll out features, measure impact, and iterate quickly.

## Categories

- developer tools & devops

## Toolkit Details

- Tools: 7

## Images

- Logo: https://logos.composio.dev/api/statsig

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for Statsig.
  - Setup:
    - Configure Api Key credentials for Statsig.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

- Enable feature flag for user cohort
- Roll out config change to 10% users
- Fetch experiment metric results for signup_flow

## 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. |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK
```python
pip install composio_openai
```

```typescript
npm install @composio/openai
```

#### Path 1, Step 2: Initialize Composio and Create Tool Router Session

Import and initialize Composio client, then create a Tool Router session
```python
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
openai = OpenAI()
session = composio.create(user_id='your-user-id')
```

```typescript
import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';

const composio = new Composio({
  provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');
```

#### Path 1, Step 3: Execute Statsig Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Statsig actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'List all feature gates for project website'
  }]
)
result = composio.provider.handle_tool_calls(
  response=response,
  user_id='your-user-id'
)
print(result)
```

```typescript
const tools = session.tools;
const response = await openai.responses.create({
  model: 'gpt-4.1',
  tools: tools,
  input: [{
    role: 'user',
    content: 'List all feature gates for project website'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK for Python or TypeScript
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
```

#### Path 2, Step 2: Initialize Client and Create Tool Router Session

Import and initialize the Composio client, then create a Tool Router session for Statsig
```python
from composio import Composio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions

composio = Composio(api_key='your-composio-api-key')
session = composio.create(user_id='your-user-id')
url = session.mcp.url
```

```typescript
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: 'your-api-key' });
const session = await composio.create('your-user-id');
console.log(`Tool Router session created: ${session.mcp.url}`);
```

#### Path 2, Step 3: Connect to AI Agent

Use the MCP server with your AI agent (Anthropic Claude or Mastra)
```python
import asyncio

options = ClaudeAgentOptions(
    permission_mode='bypassPermissions',
    mcp_servers={
        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Statsig tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query("Get recent experiment metrics for experiment 'signup_flow'")
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{
    role: 'user',
    content: 'Get recent experiment metrics for signup_flow'
  }],
  maxSteps: 5,
});

console.log(`Agent: ${text}`);
```
