Frequently Asked Questions

FAQPage Schema

How to install Malloy Publisher?▼

Run `npx skills add malloydata/publisher --all -g -y` in your terminal to install all skills in this suite globally.

What does Malloy Publisher do?▼

It serves Malloy semantic models over a REST API and one MCP endpoint, so applications and agents query governed measures and joins instead of writing raw SQL. This keeps numbers correct by construction.

How do I connect my agent to Publisher?▼

Start the server with `npx @malloy-publisher/server --port 4000`, then launch your agent from the same directory so it picks up the generated `.mcp.json`. The `malloy_*` tools then appear for discovery, querying, compiling, and reloading models.

Can I build dashboards and data apps with it?▼

Yes. The bundled skills cover tagged `.malloy` dashboards with filter controls, notebooks, and hand-authored HTML data apps served from a package's `public/` directory with no build step.

Does it work with Claude Code and other MCP clients?▼

Yes. Publisher exposes a standard streamable-HTTP MCP endpoint that works with Claude Code, Cursor, Codex, and other MCP-compatible clients.
