## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FINVIZ_GET_OPTIONS_CHAIN` | Get Options Chain | Return the options chain for one ticker, optionally restricted to an expiration date or strike price. Results use the export's dynamic columns and preserve all CSV values as strings. The response includes a bounded record prefix and the full export row count. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_GET_PORTFOLIO` | Get Portfolio | Return an existing Finviz portfolio using a configured portfolio URL or portfolio ID. Explicit fields override values parsed from portfolio_url. The response preserves CSV values as strings and includes a bounded record prefix and the full export row count. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_GET_STOCK_HISTORY` | Get Stock History | Return OHLCV price history for one ticker at a selected bar timeframe and history range. Finviz does not support every timeframe and range combination. CSV values, including prices and volume, are preserved as strings. The response includes a bounded record prefix and the full export row count. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_LIST_CALENDAR` | List Calendar | Return economic events, company earnings, or company dividends for an inclusive date range. Select the calendar with calendar_type. Results preserve dynamic CSV columns and string values and include a bounded record prefix plus the matching row count. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_LIST_GROUPS` | List Market Groups | Return aggregate Finviz market groups for a selected grouping and data view. Results use the export's dynamic columns and preserve all CSV values as strings. The response includes a bounded record prefix and the full export row count. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_LIST_INSIDER_TRANSACTIONS` | List Insider Transactions | Return recent market-wide or ticker-specific insider transactions, filtered to all transactions, purchases, or sales. Results preserve numeric-looking values and SEC links exactly as strings. The response includes a bounded record prefix and the full export row count. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_LIST_INVESTOR_HOLDINGS` | List Investor Holdings | Return a bounded prefix of one manager's or fund's complete unpaginated holdings export and report its full row count. Select the resource with investor_type and pass its Investor ID or combined slug. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_LIST_INVESTORS` | List Investors | Return the institutional-manager or fund directory, optionally narrowed by name. Records preserve Investor ID for FINVIZ_LIST_INVESTOR_HOLDINGS. max_records returns a bounded prefix, and Finviz may cap the export itself, so the result is not guaranteed to be an exhaustive directory. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_LIST_LATEST_FILINGS` | List Latest Filings | Return the latest SEC filings for one ticker, optionally filtered by filing category and ordered by filing date, report date, or form. Results preserve all CSV cells, including filing and document links, exactly as strings. The response includes a bounded record prefix and the full export row count. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_LIST_NEWS` | List News | Return market, stock, ETF, or crypto news from Finviz. Stock and ETF feeds can optionally be restricted to one ticker; market and crypto feeds are market-wide. Results use the export's dynamic CSV header and preserve every cell as a string. The response includes a bounded record prefix and the full export row count. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |
| `FINVIZ_SCREEN_STOCKS` | Screen Stocks | Return stocks from a configured Finviz screener URL or explicit screener controls. Explicit fields override values parsed from screener_url. Unknown filter codes may be silently ignored. The response preserves CSV values as strings and includes a bounded record prefix and the full export row count. A truncated response has no continuation page. Requests are paced only within one worker; external callers and multi-worker runners must serialize Finviz requests. |

#### 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')

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 Finviz Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Finviz actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',

  input=[{
    'role': 'user',
    'content': 'List top gainers in the last week'
  }]
)
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 top gainers in the last week'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output

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

Import and initialize the Composio client, then create a Tool Router session for Finviz
```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')

```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 Finviz tools.',

)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('List top gainers in the last week')
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
