Syl Guardian

# Install the MCP server Syl Guardian (`io.sylai/guardian`)

Its page: https://plug.directory/servers/io.sylai/guardian

It runs on the publisher's servers; the client connects to its URL.

Ask the person for `YOUR_X_API_KEY` and put it in place of the placeholder; never invent a value.

Use the section for the person's client.

## Claude Desktop

This server needs a header that the connector form cannot set; use Claude Code, Cursor or VS Code for it.

## Claude Code

Run in a terminal:

```sh
claude mcp add --transport http guardian https://guardian.sylai.io/mcp --header 'X-API-Key: YOUR_X_API_KEY'
```

## Cursor, Devin Desktop, LM Studio, oterm, Bob Shell, ECA, Kiro, Kiro CLI

Merge into the place for the person's client:

- Cursor: ~/.cursor/mcp.json
- Devin Desktop: ~/.config/devin/mcp_config.json
- LM Studio: mcp.json (Program › Install › Edit mcp.json)
- oterm: config.json in oterm's data folder (~/Library/Application Support/oterm on macOS, ~/.local/share/oterm on Linux, %APPDATA%\oterm on Windows)
- Bob Shell: ~/.bob/settings/mcp.json (global) or .bob/mcp.json (project)

## mcp-client-cli, TUUI, BoltAI

This server's endpoint speaks streamable HTTP, which this client's documentation does not list among its transports; use another client for it.

## Augment Code

This server needs a header, and Augment Code's documentation shows no way to send one to a remote server; use another client for it.

Then restart the client, or reload its MCP servers, and ask it to list the server's tools to confirm it started.
