factstore

A fact store for AI agents, on Postgres. Agents record what a company's systems and documents say as facts: a value for a registered attribute, in a transaction stamped with who wrote it and the document it came from. Nothing is overwritten, so the store can say what it knew on any date.

Skills that ship with it index a company's systems from their exports, and read documents and mail into facts. They leave people's personal details in the source. MIT-licensed.

Install

pip install factstore

In Claude Code, the plugin brings the MCP server and the skills:

/plugin marketplace add Victor-EU/factstore
/plugin install factstore@factstore

factstore/README.md walks through Postgres, a first store and connecting an agent.

What's here
factstore/The kernel, the MCP server, the Python SDK and the CLI
packages/Vocabulary packages: core, and ecom-ops and ecom-index for an online brand
factstore-skills/The catalogue, ontology and ingestion skills
evals/What it was tested on: a synthetic brand, and five public datasets from real companies
factstore-design.mdThe design, and what testing changed in it
factstore-build-plan.mdThe milestones, and where each stands

Status

0.1.0, alpha. The kernel's code held unchanged through every test, up to 3.2 million facts in one store. The skills passed every round on public data: product lists, a million order lines, a marketplace's duplicate customers, 100 suppliers' forms and a trader's mailbox. No company has run it on its own data yet.
