## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Coresignal MCP or direct API to search public employee profiles, enrich company research, source candidates, and build sales lead lists through natural language.

## Summary

Coresignal is a real-time public web data platform for employee, company, and professional profile intelligence.
It helps teams access fresh workforce data for research, recruiting, sales, and market analysis.

## Categories

- hr & recruiting

## Toolkit Details

- Tools: 3

## Images

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

## Authentication

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

## Suggested Prompts

- Find engineers at fast growing startups
- Research employee counts for target accounts
- Source sales leaders in fintech companies

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CORESIGNAL_GET_REAL_TIME_EMPLOYEE_PROFILE` | Get Real-Time Employee Profile | Retrieve an employee profile, using cached data up to max_age hours old (24 by default); set max_age=0 to request current data. Requires the connected account's separate Real-time Employee API entitlement and may take up to 30 seconds. |
| `CORESIGNAL_SEARCH_FAST` | Fast Search | Turn a natural-language employee, company, or job search into an Elasticsearch query, or return matching preview records. Prefer this lower-cost search unless deeper reasoning or clarification is needed; each call consumes Coresignal credits. |
| `CORESIGNAL_SEARCH_WITH_REASONING` | Search With Reasoning | Run a higher-cost natural-language search that explains its interpretation and can request clarification. Use when fast search is ambiguous or reasoning is valuable; a query-mode call consumed 100 trial credits in testing, data-mode cost varies, clarification requests do not consume credits, and the endpoint is limited to 10 requests per hour. |

## 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 Coresignal Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Coresignal actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Find current software engineers at fintech companies in Berlin using Coresignal'
  }]
)
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: 'Find current software engineers at fintech companies in Berlin using Coresignal'
  }],
});
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 Coresignal
```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 Coresignal tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Research employee headcount and hiring trends for Stripe using Coresignal')
        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: 'Research employee headcount and hiring trends for Stripe using Coresignal'
  }],
  maxSteps: 5,
});

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

## Why Use Composio?
