Search1API is a search and web data service for web, maps, and news results. It also supports crawling, screenshots, sitemaps, and structured data extraction.

14 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Search1API account to Claude via Composio Connect, enabling it to search latest climate news and summarize key developments, find coffee shops near your current location, extract product prices from this competitor website, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Search1API account

Back in Claude, ask it to connect to Search1API or give it any Search1API-related task.

For example, ask Claude to:

  • "Search latest climate news and summarize key developments"
  • "Find coffee shops near your current location"
  • "Extract product prices from this competitor website"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Search1API account is ready to use.

What is the Search1API Claude Connector, and what's possible with it?

The Search1API MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Search1API account. It provides structured and secure access to web, maps, news search, crawling, screenshots, sitemap discovery, and structured data extraction, so your agent can research topics, find places and current stories, collect website content, and extract useful data on your behalf.

  • Web and research search: Have your agent research a topic across multiple search engines, find relevant web pages, and return deduplicated results.
  • News and maps discovery: Let the agent search recent news with filters or find businesses and places on Google Maps.
  • Website crawling and discovery: Direct your agent to fetch readable content from public URLs, discover a site's sitemap, or start and check a multi-page crawl.
  • Structured data extraction: Instruct your agent to extract caller-defined information from a public webpage in a specified JSON shape.
  • Webpage capture and account insights: Have your agent take webpage screenshots, check Search1API service health, review usage, or retrieve a live trending feed.

Troubleshooting

1. Why does Claude not use the Composio connector for Search1API?

The connector can show as connected, but Claude must use it in each Search1API conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Search1API again.

2. Why does Claude show an MCP server error before Search1API connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Search1API.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Search1API.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Search1API authorization link not work?

The Composio connector is one server. Your Search1API account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Search1API connection.
  • Composio creates a fresh Search1API authorization link.
  • Open that link in your browser and finish the Search1API sign-in.

4. Why do Search1API actions fail after they worked before?

The Search1API connection can expire or lose permission.

  • Ask Claude to inspect the Search1API connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Search1API account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Search1API.
  • If the action still fails with a permission error, check that the connected account has that permission in Search1API itself.

5. How do I switch to a different Search1API account?

Claude can manage the Search1API connection for you.

  • Ask Claude to disconnect or delete the current Search1API account.
  • Ask Claude to connect Search1API again.
  • Open the new Composio authorization link for Search1API.
  • Sign in with the other Search1API account in the browser.
  • After the account connects, ask Claude to retry the Search1API task.

6. Why is my Search1API connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Search1API connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Search1API tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Search1API.

FAQ

Frequently asked questions

With a standalone Search1API MCP server, the agents and LLMs can only access a fixed set of Search1API tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Search1API and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork 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 Search1API tools.

Yes, absolutely. You can configure which Search1API 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 Search1API data and credentials are handled as safely as possible.
