Api Key

Crawlbase is a web crawling API platform for fetching pages, managing crawler queues, storing crawl results, and tracking usage. It helps developers collect web data at scale without building and maintaining crawler infrastructure.

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 Crawlbase 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 1,000+ 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 Crawlbase 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 Crawlbase

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

4. Done. You're all set with a new Crawlbase 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.

Copy MCP URL and API key from Composio dashboard

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 Crawlbase or request any Crawlbase-related task. It will prompt you to authenticate and authorize access.

5. Done!

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

The Crawlbase MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Crawlbase account. It provides structured and secure access so your agent can perform Crawlbase operations on your behalf.

Way Forward

With Crawlbase 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.

Generate User Agents

Generate one to ten realistic randomized User-Agent strings for a selected device class.

Get Crawling Usage

Return current Crawling API usage and optionally previous-month statistics for the connected Crawlbase account.

Get Storage Count

Return the number of pages currently held in Crawlbase Cloud Storage.

Get Stored Page

Retrieve the latest Crawlbase Cloud Storage page by exactly one request ID or original URL.

Get Stored Pages

FAQ

Frequently asked questions

With a standalone Crawlbase MCP server, the agents and LLMs can only access a fixed set of Crawlbase tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Crawlbase 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 Crawlbase tools.

Yes, absolutely. You can configure which Crawlbase 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 Crawlbase data and credentials are handled as safely as possible.
