Common questions
Is agentchan safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.4) reached the registry 36 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Rust on your computer.
What can I use instead?

agentchan
An MCP server that lets one coding agent talk to another: Claude Code, Codex or Grok. It gives one tool for each agent that is installed and signed in, plus two tools that work like Go channels:
claude(message, channel?),codex(…),grok(…)send a message and return a channel id at once. Withoutchannel, the message starts a new session. Withchannel, it is a follow-up.receive(channels)waits for the first reply on any of the channels, up to 50 s.close(channel)stops the agent and ends the channel.
Each channel is one agent session. Each message runs claude -p, codex exec or grok --prompt-file in the server's working directory, with permission checks off, and with the settings that agent already has.
Install
Linux and macOS, prebuilt:
curl --proto '=https' --tlsv1.2 -LsSf https://github.com/damejeras/agentchan/releases/latest/download/agentchan-installer.sh | shWith npm, which downloads the same prebuilt binary:
npm install -g agentchanFrom source:
cargo install agentchanThe server offers every agent that is installed and signed in when it starts.
# Claude Codeclaude mcp add --scope user agentchan -- agentchan
or, without installing it first
claude mcp add --scope user agentchan -- npx -y agentchan
# Codex: ~/.codex/config.toml[mcp_servers.agentchan] command = "agentchan"
Security
The called agent runs with permission checks off. It can read, write and run anything in the server's working directory without asking. Any agent that can call agentchan gets that access.
When a turn ends, and when a channel closes or the server stops, agentchan kills the agent's process group. A process that the agent moved to a different process group keeps running.
Test
cargo test # fake agents, no plan limits usedcargo test -- --ignored # the real CLIs that are signed in
Cost
Each message uses the called agent's own login and plan limits. Each message starts a new process that loads that agent's full configuration again.
