agenthop
Pair your agent with someone else's agent over a one-time code: end-to-end encrypted, no public IP needed. Needs the free agenthop program.

agenthop
Example session with this skill installed
Open an agenthop room so my colleague's agent can help me work out the pagination parameters of our API.
- Read your context and instructions
- Compiled the agenthop
Room open. Pairing code:
4821-amber-cedar-fjord-<26-character key>
Hand this whole string to the other side exactly as it is. The last part is this conversation's key; without it they cannot get in. Once they have joined and confirmed, I'll use agenthop_wait to wait for them to speak.
Next steps
- Send the whole code to your colleague (chat, email, anywhere).
- Their agent calls
agenthop_joinwith it and reads your opening line: "pagination parameters of our API". - Once they confirm, we exchange questions and answers; every line is logged to a file you can read.
Connects securely to your tools. The creator never sees your data.
About this skill
agenthop lets your AI agent talk directly to another person's agent on a different machine — no public IP on either side, just one pairing code. This skill teaches your agent to drive the agenthop_* MCP tools: open a room, join one, wait its turn, reply, send a file, and say goodbye.
Requires the agenthop program. It is a free, open-source (Apache-2.0) single-file binary, no Node.js needed: download it from https://github.com/sdyuyouth/agenthop/releases, run agenthop install, and register the MCP server it prints for your agent (Claude Code, Codex, Cursor, Gemini CLI or grok). Without it the skill has nothing to call.
What it does
- Pair with a code:
agenthop_createopens a room and returns a pairing code; the other side's agent joins withagenthop_join. - Talk in turns:
agenthop_waitreturns when it is your turn;agenthop_workingsends a receipt,agenthop_sayreplies. - Send files: up to 512 KiB, name and contents encrypted.
- Contacts and invites: save a peer once, then invite them by name with no code to pass around.
Security, plainly
Messages and files are end-to-end encrypted. The pairing code has two halves; the key half never goes to the relay, so the relay only forwards ciphertext. There is no forward secrecy, and whoever holds a code can join that room, so treat it as a one-time secret. The relay can be self-hosted (Node, or a Cloudflare Worker). Details: SECURITY.md in the repository.
Limits
Messages up to 64 KiB, files up to 512 KiB; a room disappears after ten minutes without traffic. The skill is included in English and Chinese.
