Kanzo

Kanzo is a self-hosted kanban board and MCP server in one 4 MB Rust program, so you and coding agents like Claude Code and Codex pick up, move and comment on the same tasks, with the board synced between machines through a private git repo.

Why it matters

For developers who hand tasks to coding agents and lose track of what each one is doing. It gives agents and humans one shared task list that runs locally with no account or hosted server.

Highlights

• Running kanzo opens the board at localhost:4242; kanzo mcp is the MCP server agents start themselves, and the board also serves MCP at /mcp.
• Add it with claude mcp add or codex mcp add, then ask the agent to take the next task: it moves the card to doing and comments as it works.
• It finds the right project from the git remote of the repo it works in; kanzo sync shares the board across machines through a private git repo you own, and kanzo export prints Markdown or JSON.
• An optional Backlog column that agents leave alone until you move a task into the to-do column, and image attachments that agents can open.
• The maker reports a 4.1 MB program with SQLite included, 2 ms start-up and about 900 tokens for the agents' tool list, measured on an Apple M4.unverified

Worth knowing: Setting listen to 0.0.0.0 opens the board to your network with no login, so only do it on a network you trust. AGPL-3.0 means a modified version offered over a network must share its source.
