## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FINNHUB_GET_COMPANY_FINANCIAL_METRICS` | Get Company Financial Metrics | Get Finnhub's current key ratios and annual or quarterly metric series for one company. |
| `FINNHUB_GET_COMPANY_PROFILE` | Get Company Profile | Look up a company profile by exactly one ticker, ISIN, or CUSIP. |
| `FINNHUB_GET_MARKET_STATUS` | Get Market Status | Check whether an exchange is open now and identify its current session, timezone, or holiday. |
| `FINNHUB_GET_QUOTE` | Get Quote | Get the latest price snapshot for one Finnhub symbol. Unknown symbols fail explicitly instead of returning a misleading zero quote. |
| `FINNHUB_GET_QUOTES` | Get Quotes | Get price snapshots for 1-10 Finnhub symbols in one tool call. This uses one Finnhub API request per symbol and reports unrecognized symbols per result. |
| `FINNHUB_GET_REPORTED_FINANCIALS` | Get Reported Financials | Retrieve as-reported balance-sheet, cash-flow, and income-statement data for a company or filing. A ticker, CIK, or accession number is required; large statement details are available only when requested. |
| `FINNHUB_LIST_CALENDAR_EVENTS` | List Calendar Events | List earnings releases or IPO events in an ordered date range. Use an earnings ticker or a narrow date window because Finnhub does not paginate or server-limit these calendars. |
| `FINNHUB_LIST_EARNINGS_RESULTS` | List Earnings Results | List a company's recent actual versus estimated earnings and surprise values. |
| `FINNHUB_LIST_SEC_FILINGS` | List SEC Filings | List SEC filing metadata; a ticker, CIK, or accession number is required, optionally filtered by form and an ordered date range. |
| `FINNHUB_SEARCH_NEWS` | Search News | Get broad market news by category or company-specific news for an ordered date range. Use narrow company date ranges because Finnhub does not paginate or server-limit company news. |
| `FINNHUB_SEARCH_SYMBOLS` | Search Symbols | Find tradable symbols by ticker, company name, ISIN, or CUSIP, optionally restricted to an exchange. |

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 Finnhub Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Finnhub actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'YOUR_SPECIFIC_PROMPT_HERE'
  }]
)
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: 'YOUR_SPECIFIC_PROMPT_HERE'
  }],
});
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 Finnhub
```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 Finnhub tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('YOUR_SPECIFIC_PROMPT_HERE')
        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: 'YOUR_SPECIFIC_PROMPT_HERE'
  }],
  maxSteps: 5,
});

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