About Honcho
Honcho is an MCP server published by the GitHub account plastic-labs. Memory that reasons: continual learning for stateful agents. Better context, fewer tokens.
It is hosted by the publisher at one address, so there is nothing to install: your AI client connects to it over the internet.
It asks for no keys or passwords.
Version 3.0.0 was published on 12 August 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 6 automated checks on registry metadata: 3 pass, 0 warn, 0 fail, 3 info. How we check.
