01 · Install Search1 API

before you install - you'll need

SEARCH1API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add superagents-lab-search1api-mcp --transport http https://mcp.search1api.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "superagents-lab-search1api-mcp": {
      "url": "https://mcp.search1api.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to mcp.search1api.com

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license MIT - declared in the repository

npm package search1api-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.superagents-lab is GitHub-verified and matches the repo owner
