CofferLocal-first AI agent vault

One secure, shared interface for every AI agent on your machine. Configure your tools, skills, knowledge, and memory once — every agent sees the same vault. Nothing leaves your machine.

Local-first & encrypted

All state lives on your machine — no cloud accounts, no vendor lock-in. Secrets are Fernet-encrypted at rest behind a master key you control.

One MCP endpoint

Aggregate every upstream MCP server and re-expose their tools namespaced as <server>__<tool>. Claude Code, Codex, and any MCP client see exactly the same tools.

Skills · Knowledge · Memory

Keep one master skill library and deliver it into each agent; curate knowledge bases your agents can search; share one memory across every agent.

Chat with any agent

Talk to Coffer's built-in agent — or drive Claude Code and Codex — from a streamed chat, in the web or desktop app.

Reach agents anywhere

Pair a Telegram or SeaTalk channel and chat with your agents from your phone. Multi-machine sync keeps every machine consistent over a git repo you own.

CLI · Web · Desktop

Drive the whole vault from a terminal, a local web UI, or the desktop app. Agents auto-discover the daemon — no port or token wiring.

How it works

Coffer is a long-lived local daemon that holds your vault. The MCP gateway is one part of it: every AI agent connects through one auto-discovering endpoint and sees the same tools, skills, knowledge, and memory — while secrets stay encrypted and nothing leaves your machine unless you sync it to a git remote you own.

Quickstart

bash

# Aggregate an upstream MCP server, then point Claude Code at Coffer.
coffer mcp add filesystem --stdio "npx -y @modelcontextprotocol/server-filesystem /tmp"
claude mcp add coffer coffer-mcp-shim

# Curate a knowledge base and a shared skill — your agents pick them up automatically.
coffer kb create handbook
coffer skill import ./my-skill

# Chat with Coffer's built-in agent from the terminal.
coffer chat -m "what MCP servers and knowledge bases do I have?"
