Kagi MCP Server

An MCP server backed by the Kagi API. It exposes search, extraction, summarization, and FastGPT tools to MCP-compatible clients.

Tools

• kagi_extract - fetch a page's full content as markdown.
• kagi_summarizer - summarize a URL as prose or key takeaways.
• kagi_fastgpt - answer a question with live web search, synthesis, and numbered references.

Requirements

• A Kagi API key in KAGI_API_KEY.
• uv for the recommended uvx install path.

Install uv:

curl -LsSf https://astral.sh/uv/install.sh | sh

Windows:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
