Malloy Publisher Server
malloy-publisher · MCP server
Malloy Publisher Server is an Express.js server that manages and serves Malloy semantic models, packages and queries. It exposes them through a REST API and an MCP endpoint for agents, which also offers the bundled agent skills as prompts. Flat CSV, Parquet and Excel packages get their own DuckDB connection automatically, and a scaffolding command can create a starter package with sample data. It suits teams who want agents and BI tools to query one shared Malloy model.

Why it's useful
Agents and BI tools can ask questions of one shared Malloy model instead of each writing its own SQL against raw tables.
What you could do with it
- Start a Malloy package from a CSV, Parquet or Excel file and let your agent query it.
- Point the server at a folder of existing Malloy models and watch it for local edits while you author.
- Pull the bundled analysis guidance into an agent as ready-made prompts through the MCP endpoint.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Licence and provenance
- finding
- no LICENCE file at the root (.)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
An open source MCP and REST server for Malloy semantic models, so AI agents, applications, and BI tools query one governed model instead of raw SQL.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.9.6, the file with digest sha512-mGAXfFPP+iIw9tZiLstPBM2ATVgUXb/fnUwiPQO3Hmo7A2CMDLK7DwMDFJKltdM65QEzh6bIeCpoZaKwCNe+zA==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
