Turn your apps into a SQL database your agent can query.

Gmail, Office 365, Slack, Teams, Salesforce, and 600+ more — synced into one read-only Postgres for your agents. ContextBase keeps it fresh.

Open source. Runs on your machine.

1.0 — Unlocks

Build things that weren't practical before.

BREADTH — Questions that span your tools.

“Which customers emailed us last week and still have an open ticket?” is one JOIN across two sources. Your agent writes it on the spot — nobody had to anticipate the question or build an endpoint for it.

SECURITY — Agents you can fully lock down.

The agent needs exactly one thing: a connection string. No API keys, no OAuth tokens, no web access — you can lock it in a sandbox and it'll still do its job.

DEBUGGING — Agents you can actually debug.

When the agent gets something wrong, you can look at exactly what it could see. Run the same query it ran, look at the rows, check when each row last changed. The postmortem is a SELECT, not an archaeology dig.

ISOLATION — A workspace per agent.

A workspace is a directory with one mqp.json and its own embedded Postgres. Spin one up for every project, agent, or experiment. They cost nothing, and deleting one is deleting a folder.

PERSONAL — Agents over your own life.

Browser history, bookmarks, iMessage, WhatsApp, Apple Reminders, your Claude Code sessions — local sources that no cloud platform reaches, and that need no auth at all. Useful before you've connected a single cloud account.

FRESHNESS — Set up once, stays current.

ContextBase keeps syncing on its own. You don't babysit export scripts, and every row records when the source last changed — so freshness is something you can query, not something you hope for.
