What is the Kage MCP Server?

Verified memory for coding agents: claims cited against code, stale withheld, savings receipts.

The short version

In June 2026 Google shipped OKF (Open Knowledge Format): a standard for keeping knowledge as plain Markdown concept files in your repo, vendor-neutral, no lock-in. It standardizes the store and stops there. Verification, freshness, and staleness are explicitly out of scope for v0.1. Kage is the framework that maintains it. It captures what your coding agents learn as a conformant OKF bundle in git, then keeps every concept honest against your real code: a memory whose cited code no longer exists is rejected at write time, and one

Kage is a memory layer for coding agents. As your agent works, it captures what it learns (decisions, bug fixes, conventions, how the code fits together) as Open Knowledge Format (OKF) concept files committed in your repo under .agent_memory/. The next session (yours or a teammate's) starts already knowing it, instead of re-reading or re-asking.
