Connect the MCP.

Add one address to your AI tool and sign in once. The skill works without it; with it, your agent gets the block catalogue as it stands today.

Updated 12 November 2026. Struq skill 0.5.0.

The address

https://struq.app/api/mcp

A remote MCP server over HTTP. It needs a free Struq account, because your client connects as you. The four catalogue tools are free.

Your client

Claude Code

Run this in a terminal. The second line lists your servers, so you can see Struq arrived.

claude mcp add --transport http --scope user struq https://struq.app/api/mcpclaude mcp list

Without --scope user the server lands in this project only, and your next repository will not see it.

Codex

Add this to ~/.codex/config.toml (on Windows %USERPROFILE%\.codex\config.toml).

[mcp_servers.struq]url = "https://struq.app/api/mcp"

Codex reads its server list when it starts. Open a new window after saving.

Cursor

Add this to ~/.cursor/mcp.json (on Windows %USERPROFILE%\.cursor\mcp.json).

{"mcpServers": {"struq": {"url": "https://struq.app/api/mcp"}}}

Cursor has no sign-in command. After the reload, open Settings, then MCP, and approve Struq there.

VS Code

Open the Command Palette, run MCP: Open User Configuration and add this.

{"servers": {"struq": {"type": "http","url": "https://struq.app/api/mcp"}}}

The top key is servers, not mcpServers, and "type": "http" is required. The Copilot CLI uses mcpServers instead, in the same shape.

Windsurf

Add this to ~/.codeium/windsurf/mcp_config.json (on Windows %USERPROFILE%\.codeium\windsurf\mcp_config.json).

{"mcpServers": {"struq": {"serverUrl": "https://struq.app/api/mcp"}}}

Windsurf reads serverUrl, not url.

Antigravity

Add this to ~/.gemini/config/mcp_config.json (on Windows %USERPROFILE%\.gemini\config\mcp_config.json).

{"mcpServers": {"struq": {"serverUrl": "https://struq.app/api/mcp"}}}

Antigravity reads serverUrl, not url. The IDE and the CLI share this file, so one setup covers both.

Claude, desktop and web

Open Settings, then Connectors, then Add custom connector. Name it Struq and paste the address.

https://struq.app/api/mcp

Custom connectors need a paid Claude plan. On a free plan, use Claude Code instead.

The first time your agent calls Struq, your client opens a sign-in page. Sign in, then choose what your agent may do: read only, or also save to your library.

You sign in once per client. It asks again only when the sign-in expires or you revoke it.

Check it works

Ask your agent which Struq tools it sees.

Which Struq tools can you see?

Four on a free account, twelve on Pro. The tools page says what each one does.

Disconnect

Revoke the connection in your Struq account, under AI connections. Access stops at once. Remove the lines from your client’s config as well, or it keeps asking you to sign in.
