Agent Skills

An MCP server exposes tools an agent can call. A skill provides instructions for choosing those tools, reading sources, and answering with citations. Search1API provides a skill with the published Claude plugin and a separate standalone skill for agents that use the s1 CLI.

Claude pluginCopy Anchor Link

For Claude apps, Cowork, and Claude Code, install Search1API plugin. You can also find it under Customize → Plugins → Discover by searching for Search1API. The published plugin bundles an Agent Skill with the remote MCP tools. Connect Search1API through OAuth after adding the plugin. Plugins require a paid Claude plan.

For the same tools without the bundled skill, add Search1API connector. See the Claude guide for installation steps and Claude Code account sync, or MCP setup for manual configuration.

Standalone CLI skillCopy Anchor Link

For terminal agents that use the s1 CLI:

npm install -g search1api-cli
npx skills add superagents-lab/search1api-cli
s1 login

This standalone skill drives the s1 CLI, so the CLI has to be installed and logged in first. If it isn't, the skill will walk the user through it. The Claude plugin uses MCP tools directly instead.

What the skill guidesCopy Anchor Link

Both skills provide guidance for adapting web access to the request:

• Read a shared URL with crawl.
• Use a small result set for a quick lookup; for a research question, search more broadly and read relevant pages for full text.
• Apply a recency filter for requests such as "latest" or "today".
• Combine tools for research, URL summarization, and trending-topic exploration.
• Synthesize findings and cite source URLs.

The Claude plugin skill uses MCP parameters such as max_results and time_range. The standalone skill uses CLI flags such as -n and -t.

Using itCopy Anchor Link

Once installed, just talk to your agent normally:

• "search for the latest AI news"
• "what does this link say? https://example.com"
• "what's trending on GitHub?"
• "research quantum computing thoroughly"

Claude or your agent uses the skill's instructions to choose a tool or command, the search service, the result count, and whether to read pages.

CostCopy Anchor Link

Both skills use the same Search1API account credits as direct API calls. The skill itself adds no separate Search1API fee; workflows that make more searches or read more pages use more credits. See Credits and limits.
