Kagi MCP Server
An MCP server backed by the Kagi API. It exposes search and extraction tools to MCP-compatible clients.
Tools
kagi_search_fetch - web, news, videos, podcasts, and image search with optional page extracts, filters, and Kagi lenses.kagi_extract - fetch a page's full content as markdown.
Note: The previous kagi_fastgpt and kagi_summarizer tools have been removed. Both are planned to return in a future release.
Hosted Server
We run a hosted MCP server at https://mcp.kagi.com/mcp — no install required. Point any HTTP-capable MCP client at it and authenticate with your Kagi API key.
OAuth2 isn't supported yet (it's on our roadmap), so for now grab your API key from the dashboard and pass it via Bearer HTTP authentication.
Example with Claude Code:
claude mcp add kagi https://mcp.kagi.com/mcp --transport http --header "Authorization: Bearer $(read -sp 'API key: ' k; echo $k)" --scope user
Prefer to run it yourself? See Client Setup for the local uvx install, or Self-Hosting to host the HTTP server on your own infrastructure.
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"
Usage Examples
- Search:
Who was Time's 2024 person of the year?
- Extract:
extract the full content of https://en.wikipedia.org/wiki/Model_Context_Protocol
Configuration
| Environment variable | Description |
|---|
KAGI_API_KEY | Required Kagi API key. |
FASTMCP_LOG_LEVEL | Logging level, for example ERROR. |
KAGI_SEARCH_TIMEOUT | Search timeout in seconds. Defaults to 10. |
KAGI_EXTRACT_TIMEOUT | Extract timeout in seconds. Defaults to 30. |
KAGI_MAX_RETRIES | Max retry attempts after the first request. Defaults to 2; set 0 to disable retries. |
KAGI_HIDDEN_PARAMS | Comma-separated search params to hide from the LLM-facing schema. |
Hideable search params:
workflow, extract_count, limit, include_domains, exclude_domains, time_relative, after, before, file_type, lens_id
Example:
KAGI_HIDDEN_PARAMS="extract_count,after,before,time_relative,include_domains,exclude_domains"
Local Development
git clone https://github.com/kagisearch/kagimcp.git
cd kagimcp
uv sync
Run locally over stdio:
KAGI_API_KEY=<YOUR_API_KEY_HERE> uv run kagimcp
Run with streamable HTTP transport:
KAGI_API_KEY=<YOUR_API_KEY_HERE> uv run kagimcp --http --host 0.0.0.0 --port 8000
Self-Hosting
HTTP mode is multi-tenant: each request supplies its API key via the
Authorization: Bearer <key> header instead of a server-wide env var, so one
instance can serve multiple users. The repo ships a Dockerfile that installs a pinned kagimcp from PyPI and
runs it in HTTP mode. The container respects $PORT so it works on any
platform that injects one (Railway, Render, Cloud Run, Fly.io, etc.).
Build and run locally:
docker build -t kagimcp-hosted .
docker run --rm -p 8000:8000 kagimcp-hosted
Smoke test:
curl -sL http://127.0.0.1:8000/mcp -X POST \
-H "authorization: Bearer $KAGI_API_KEY" \
-H "content-type: application/json" \
-H "accept: application/json, text/event-stream" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
To bump the version in production, edit the pin in the Dockerfile and redeploy.
Debugging
Inspect the published package:
npx @modelcontextprotocol/inspector uvx kagimcp
Inspect a local checkout:
npx @modelcontextprotocol/inspector uv --directory /ABSOLUTE/PATH/TO/kagimcp run kagimcp
The inspector is usually available at http://localhost:5173.
Prerelease Instructions
If using a prerelease build, the same installation instructions apply, but use uvx --prerelease allow --from kagimcp==1.0.0rc2 kagimcp instead of uvx kagimcp (replace 1.0.0rc2 with whatever version you're wanting to install).
