Api Key

Crunchbase is a business intelligence platform for company, people, funding, and market data. It helps teams research private companies and uncover investment and market insights.

7 Tools

Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.

This guide explains the easiest and most robust way to connect your Crunchbase account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,500+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Crunchbase with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Crunchbase

Ask your agent to connect to Crunchbase, or simply request any Crunchbase-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Crunchbase connection.

Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Crunchbase or request any Crunchbase-related task. It will prompt you to authenticate and authorize access.

5. Done!

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

The Crunchbase MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Crunchbase account. It provides structured and secure access to company, people, funding, financial, prediction, and market insight data, so your agent can search records, retrieve detailed company and people information, explore related records, and review available data fields on your behalf.

  • Company and people research: Have your agent search Crunchbase collections using multiple conditions, then retrieve detailed information about relevant companies, people, and other records.
  • Funding and market analysis: Direct your agent to find and compare records across licensed Crunchbase collections for research on funding activity, financial details, predictions, and market insights.
  • Related record discovery: Let the agent explore related information connected to a company or person, such as associated organizations, funding activity, or other available relationship data.
  • Entity lookup from everyday language: Instruct your agent to find the right Crunchbase company or person record from a name, keyword, or web address before researching it further.
  • Data availability and change tracking: Have your agent review the fields and collections available through your Crunchbase access, or identify records that have been deleted.

Way Forward

With Crunchbase connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

FAQ

Frequently asked questions

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

Yes, you can. Hermes 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 Crunchbase tools.

Yes, absolutely. You can configure which Crunchbase 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.

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 Crunchbase data and credentials are handled as safely as possible.
