Kagi MCP server

Setup Intructions

Before anything, unless you are just using non-search tools, ensure you have access to the search API. It is currently in closed beta and available upon request. Please reach out to [email protected] for an invite.

Install uv first.

MacOS/Linux:

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

Windows:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
```\n\n### Installing via Smithery

Alternatively, you can install Kagi for Claude Desktop via [Smithery](https://smithery.ai/server/kagimcp):

```bash
npx -y @smithery/cli install kagimcp --client claude

Setup with Claude## Claude Desktop

// claude_desktop_config.json
// Can find location through:
// Hamburger Menu -> File -> Settings -> Developer -> Edit Config
{
  "mcpServers": {
    "kagi": {
      "command": "uvx",
      "args": ["kagimcp"],
      "env": {
        "KAGI_API_KEY": "YOUR_API_KEY_HERE",
        "KAGI_SUMMARIZER_ENGINE": "YOUR_ENGINE_CHOICE_HERE" // Defaults to "cecil" engine if env var not present
      }
    }
  }
}
```\n\n#### Claude Code
Add the Kagi mcp server with the following command (setting summarizer engine optional):

```bash
claude mcp add kagi -e KAGI_API_KEY="YOUR_API_KEY_HERE" KAGI_SUMMARIZER_ENGINE="YOUR_ENGINE_CHOICE_HERE" -- uvx kagimcp

Now claude code can use the Kagi mcp server. However, claude code comes with its own web search functionality by default, which may conflict with Kagi. You can disable claude's web search functionality with the following in your claude code settings file (~/.claude/settings.json):

{
  "permissions": {
    "deny": [
      "WebSearch"
    ]
  }
}

Pose query that requires use of a tool

e.g. "Who was time's 2024 person of the year?" for search, or "summarize this video: https://www.youtube.com/watch?v=jNQXAC9IVRw" for summarizer.

Debugging

Run:

npx @modelcontextprotocol/inspector uvx kagimcp

Local/Dev Setup Instructions# Clone repo

git clone https://github.com/kagisearch/kagimcp.git

Install dependencies

Install uv first.

MacOS/Linux:

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

Windows:

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

Then install MCP server dependencies:

cd kagimcp

# Create virtual environment and activate it
uv venv

source .venv/bin/activate # MacOS/Linux\n\n# OR
.venv/Scripts/activate # Windows

# Install dependencies
uv sync
```\n\n### Setup with Claude Desktop## Using MCP CLI SDK
```bash\n\n# `pip install mcp[cli]` if you haven't
mcp install /ABSOLUTE/PATH/TO/PARENT/FOLDER/kagimcp/src/kagimcp/server.py -v "KAGI_API_KEY=API_KEY_HERE"

Manually

{
  "mcpServers": {
    "kagi": {
      "command": "uv",
      "args": [
        "--directory",
        "/ABSOLUTE/PATH/TO/PARENT/FOLDER/kagimcp",
        "run",
        "kagimcp"
      ],
      "env": {
        "KAGI_API_KEY": "YOUR_API_KEY_HERE",
        "KAGI_SUMMARIZER_ENGINE": "YOUR_ENGINE_CHOICE_HERE" // Defaults to "cecil" engine if env var not present
      }
    }
  }
}

Pose query that requires use of a tool

e.g. "Who was time's 2024 person of the year?" for search, or "summarize this video: https://www.youtube.com/watch?v=jNQXAC9IVRw" for summarizer.

Debugging

Run: ```bash\n\n# If mcp cli installed (pip install mcp[cli]) mcp dev /ABSOLUTE/PATH/TO/PARENT/FOLDER/kagimcp/src/kagimcp/server.py

If not

npx @modelcontextprotocol/inspector
uv \

• -directory /ABSOLUTE/PATH/TO/PARENT/FOLDER/kagimcp
  run
  kagimcp

Then access MCP Inspector at `http://localhost:5173`. You may need to add your Kagi API key in the environment variables in the inspector under `KAGI_API_KEY`.

# Advanced Configuration
- Level of logging is adjustable through the `FASTMCP_LOG_LEVEL` environment variable (e.g. `FASTMCP_LOG_LEVEL="ERROR"`)
- Relevant issue: https://github.com/kagisearch/kagimcp/issues/4
- Summarizer engine can be customized using the `KAGI_SUMMARIZER_ENGINE` environment variable (e.g. `KAGI_SUMMARIZER_ENGINE="daphne"`)
- Learn about the different summarization engines [here](https://help.kagi.com/kagi/api/summarizer.html#summarization-engines)
