Agenthop: MCP server, setup and security
Agenthop is an open-source MCP server that lets an AI agent connect remote agents and exchange files through an encrypted relay. Its repository has 6 stars and its last commit is from October 17, 2026 and it is licensed under Apache-2.0.
What Agenthop does
According to its repository: “Let two agents on machines with no public address talk directly: pair with a short code over an end-to-end encrypted relay (hosted or self-hosted), send files, and invite saved contacts by name.”
An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Agenthop is listed under Messaging and email, a category of 107 servers in the directory, where it ranks #92 by stars.
Topics declared by the repository: a2a, agent, ai-agents, cli, cloudflare-workers, relay.
Installing and connecting Agenthop
No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.
Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript. Listed systems: macOS, Windows, Linux.
Security: what to check
An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.
None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Agenthop. That does not replace reading the code.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on September 22, 2026, the sdyuyouth/agenthop repository has 6 stars and 2 forks, with 0 open issues. It has more stars than 17% of the servers in the directory. It received changes this month.
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
