Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.04108 | $0.04108 |
| Opus 5 | $0.02054 | $0.02054 |
| Sonnet 5 | $0.00822 | $0.00822 |
| Haiku 4.5 | $0.00411 | $0.00411 |
Grade A, and why
loopsy AGENTS.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **MCP tools**: If MCP tools (`loopsy_context_set`, etc.) are working, use them. If they have auth issues, fall back to the REST API directly via curl or a Node.js script How it starts
The opening of the file, as written. The whole thing — 406 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Loopsy - Cross-Machine Communication for AI Coding Agents
What is Loopsy?
Loopsy enables AI coding agent instances (Claude Code, Gemini CLI, Codex CLI, etc.) on different machines to communicate. You can:
- Run commands on remote machines
- Transfer files between machines
- Share context (key-value state) between AI coding agent instances
Setup
- Run
loopsy initon each machine to generate config and API key - Run
loopsy starton each machine to start the daemon - Exchange API keys between machines (add to
~/.loopsy/config.yamlunderauth.allowedKeys) - Peers auto-discover via mDNS, or add manually:
loopsy peers add <ip>
MCP Tools Available
When the Loopsy MCP server is running, you have these tools:
loopsy_list_peers- See all machines on the networkloopsy_execute- Run a command on a remote machineloopsy_transfer_file- Push/pull files between machinesloopsy_list_remote_files- Browse files on a remote machineloopsy_context_set- Store shared state on a peerloopsy_context_get- Retrieve shared state from a peerloopsy_peer_status- Check a peer's healthloopsy_broadcast_context- Set context on ALL peersloopsy_context_list- List context entries with optional prefix filterloopsy_context_delete- Delete a context entry by keyloopsy_send_message- Send a protocol-compliant message to a peer (handles envelope, inbox key, outbox copy, TTL)loopsy_check_inbox- Check your inbox for new messagesloopsy_ack_message- Acknowledge a received message (see Known Issues)loopsy_check_ack- Check if a peer has acknowledged your messages
Messaging Protocol v1
This section defines the standard protocol for AI coding agent instances to communicate reliably across machines. Follow these conventions exactly so that any new machine joining the network can participate immediately.
Key Concepts
- Inbox: Messages addressed to you, stored on YOUR machine by the sender
- Outbox: Local copies of messages you sent, stored on YOUR machine
- ACK: Acknowledgment that a message was read, stored on the SENDER's machine by the receiver
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

loopsy AGENTS.md is an instructions file published in the GitHub repository leox255/loopsy (139 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 4,108 tokens to every session, about $0.0205 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
