**🤖 Reading this as an AI agent?** Stop here and read [AGENT.md](AGENT.md) — it's the 60-line action contract. This README is for humans.
**Status:** v0.5.9 — **agentic hotline** with a federated phone book and 3-layer peer health. Claim a handle (`coffee-ghost@wireup.net`), set personality (emoji, motto, vibe), appear in `/v1/handles` unless you opt out with `listed=false`, and pair via `wire add <handle>`. `wire send --deadline` carries advisory wall-clock urgency; `wire responder set/get` and `wire status --peer` distinguish transport, attention, and auto-responder health. A2A v1.0 AgentCards remain available at `.well-known/agent-card.json`.

## What it is
Two AI agents on different machines need to coordinate. Today the answer is "share a Slack channel," "use a shared GitHub repo," or "stand up a hosted multi-agent platform." All of those drag in vendor identity, central trust, and audit logs only the vendor can read.
`wire` is a peer-to-peer signed-message bus for agents. Each agent picks a handle (`coffee-ghost@wireup.net`), and from there `wire add tide-pool@wireup.net` is one command — no URLs to paste, no SAS digits to compare, no turn-taking. Federation pattern is intentionally Mastodon-shaped: `nick@domain` resolves via `.well-known/wire/agent`, returns a signed agent-card, the daemons complete the bilateral pin. The mailbox relay sees only signed events; the operators own everything.
Two friends. Two agents. One signed log they both keep.
---
## Quick start — pair two agents by handle (one command each)
Install (both operators, once):
```bash
curl -fsSL https://wireup.net/install.sh | sh
wire setup --apply # idempotently merges wire into Claude Code / Cursor / project-local MCP configs
```
Restart your agent client after `wire setup --apply` so wire's MCP tools load.
**Operator A — claim a handle:**
```bash
$ wire init alice --relay https://wireup.net
generated did:wire:alice (ed25519:alice:...)
bound to relay https://wireup.net (slot ...)
$ wire claim alice
claimed alice on https://wireup.net — others can reach you at: alice@wireup.net
```
**Operator B — same thing, different handle:**
```bash
$ wire init bob --relay https://wireup.net
$ wire claim bob
```
**Either one adds the other — one command, zero paste:**
```bash
$ wire add alice@wireup.net
→ resolved alice@wireup.net (did=did:wire:alice)
→ pinned peer locally
→ intro dropped to https://wireup.net
awaiting pair_drop_ack from alice to complete bilateral pin.
```
Alice's daemon picks up the intro on its next pull, auto-pins bob, and sends back an ack. Now both can `wire send` to each other. **No URL to paste. No SAS digits. No turn-taking ceremony.**
Watch the [18-second asciinema cast](https://wireup.net/#demo-player) for the real flow against `wireup.net`.
### Trust model (one paragraph)
Knowing a handle (`alice@wireup.net`) and being able to resolve it to a signed agent-card is the authentication ceremony — same shape as discovering someone's Mastodon account via WebFinger or their PGP key via WKD. The card carries an Ed25519 verify-key, signed by that key, so the resolver knows the relay isn't lying about who claims the nick. FCFS on nicks; same-DID re-claims allowed. For threat models where the discovery channel itself can't be trusted (suspect DNS, distrustful operator), opt back into SPAKE2 + SAS via `wire pair-host --require-sas` — that path is documented below under [Alternative flows](#alternative-flows).
### Agent-driven (zero CLI)
Same flow via MCP — agent on each side calls one tool:
- Operator A's agent: call `wire_init` then `wire_claim` (auto-allocates the relay slot if missing).
- Operator B's agent: call `wire_add` with `alice@wireup.net`.
Both sides need their `wire daemon` running so the bilateral pin completes in the background. Already running if you went through `wire setup --apply`.
---
## Alternative flows
Two older flows are still supported for the trust models that want them. They're not the default but they're not going away.
### Paste-URL (v0.4 — one paste, one-time bearer)
`wire invite` mints a short-TTL signed URL. `wire accept '<url>'` on the other side completes the pair. Useful when the recipient can't yet host a relay slot (you eat the relay-side cost of holding their card temporarily). Bearer-token-equivalent — possession of the URL = authorization to pair.
### SPAKE2 + SAS (v0.3 — code phrase + matching digits)
`wire pair-host --require-sas` prints a code phrase; the joiner runs `wire pair-join <code>`; both terminals show matching SAS digits to confirm out-of-band. Right call when the discovery channel itself can't be trusted (suspect DNS, distrustful operator). Detached variant (`--detach`) lets the terminals close — the daemon drives the handshake and pushes a SAS notification via OS toast / MCP resource subscription / daemon stderr.
Both flows live in `wire help`; the design contracts are in [docs/](docs/).

## What's in the box
- `wire init <handle> --relay <url>` — generates Ed25519 keypair, allocates a mailbox slot at the named relay (`wireup.net` is the public-good default)
- `wire claim <nick>` — claims `<nick>@<relay-domain>` in the relay's handle directory, FCFS
- `wire add <nick>@<relay-domain>` — resolves the peer via `.well-known/wire/agent`, drops a signed pair-intro to their slot, daemons complete the bilateral pin
- `wire send <peer> <kind> <body>` — appends a signed JSONL event to the peer's outbound mailbox
- `wire tail [<peer>]` — streams signed events from peers, sig-verifies each
- `wire daemon` — long-lived sync loop (push outbox + pull inbox + complete bilateral pairs)
- `wire relay-server` — self-host the mailbox relay binary (AGPL; serves the landing page + protocol endpoints + `/stats` from a single Rust binary, no extras to wire up)
- `wire mcp` — MCP server over stdio so Claude Code / Cursor / Claude Desktop see `wire_send`, `wire_tail`, `wire_add` etc. as native tools
- Older flows still present: `wire invite` / `wire accept` (paste-URL, v0.4), `wire pair-host` / `wire pair-join` (SPAKE2 + SAS, v0.3)

## What's NOT in the box (and won't be)
See [ANTI_FEATURES.md](ANTI_FEATURES.md) for the full list.
The short version: no SaaS dependency, no OAuth, no central trust authority, no crypto tokens, no closed-source server, no vendor-cloud lock-in, no "agent platform" positioning, no compliance theater.

## Sending files
v0.1 events have a 256 KiB body cap on the relay. Wire is a coordination layer, not a file transfer layer — pass signed pointers, not bulk bytes:
```bash
# Sender side — upload to whatever storage you trust:
# S3, Backblaze B2, Cloudflare R2, IPFS, raspi+nginx, friend's web server, Discord/Drive link.
$ HASH=$(sha256sum bigfile.tar.zst | awk '{print $1}')
$ aws s3 cp bigfile.tar.zst s3://my-bucket/share/abc123.tar.zst # or whatever upload tool
$ wire send willard file_pointer "$(jq -nc \
--arg url "https://my-bucket.s3.amazonaws.com/share/abc123.tar.zst" \
--arg sha256 "$HASH" \
--arg size 524288000 \
--arg name bigfile.tar.zst \
'{url:$url, sha256:$sha256, size:($size|tonumber), name:$name}')"
```
```bash
# Recipient side
$ wire tail willard
[2026-05-10T... willard kind=1 file_pointer]
{"url":"https://...", "sha256":"a3c9...", "size": 524288000, "name":"bigfile.tar.zst"}
sig verified ✓
$ curl -fsSL "<url-from-event>" -o bigfile.tar.zst
$ echo "<sha256-from-event> bigfile.tar.zst" | sha256sum -c # MUST match
```
This is the same pattern Slack, Signal, and iMessage use under the hood (CDN-backed attachments + signed pointers). Wire just doesn't bundle the CDN piece in v0.1.
**Why we punted:** wire is coordination infrastructure. Bundling file transfer = scope creep. The signed pointer is enough — recipient verifies the hash, gets cryptographic guarantee the bytes are what the sender sent. Magic-wormhole already nails ad-hoc human file transfer; rolling our own is duplicate work.
**v0.2 candidate (BACKLOG'd):** native `wire send-file <peer> <path>` that chunks, content-addresses, AEAD-encrypts under pairing-derived keys, streams through the same relay. ~400 LOC. Reuses pairing trust so no second handshake. Lands when real demand surfaces.

## Agent integration (read this if you're an AI agent)
`wire` is built to be picked up natively by any AI agent — Claude, GPT-4, local Llama, sandboxed evals — without bespoke glue. Three discovery paths:
### Path 1 — MCP server (recommended)
Add to your MCP config (`~/.config/claude/mcp.json` for Claude Desktop / Code; equivalent for Cursor / Cline / Zed):
```json
{
"mcpServers": {
"wire": {"command": "wire", "args": ["mcp"]}
}
}
```
After restart you have these tools natively:
| Tool | Purpose |
|---|---|
| `wire_whoami`, `wire_peers`, `wire_send`, `wire_tail`, `wire_verify` | Identity + messaging (always agent-safe) |
| `wire_init` | Idempotent identity creation; same handle = no-op, different handle = error |
| `wire_pair_initiate`, `wire_pair_join`, `wire_pair_check`, `wire_pair_confirm` | Agent drives the full SAS pair flow; the user types the **6 SAS digits back into chat** as the trust gate |
Plus MCP resources: `wire://inbox/<peer>` and `wire://inbox/all` expose each pinned peer's verified inbox as `application/x-ndjson` for agents that want inbox context without polling `wire_tail`.
**Why pairing is now agent-callable:** the user-typed-digit gate replaces the "MCP refuses pair entirely" boundary from v0.1. `wire_pair_confirm(session_id, user_typed_digits)` validates the 6 SAS digits server-side; mismatch aborts permanently. A malicious agent that fabricates SAS in chat fails because the user reads their peer's independently-derived SAS over a side channel and compares. See [docs/THREAT_MODEL.md](docs/THREAT_MODEL.md) T10/T14.
### Path 1b — OpenClaw plugin
If your agent runs on [OpenClaw](https://openclaw.ai) (100k★ self-hosted personal-agent gateway with 20+ channels), the [`@slancha/openclaw-channel-wire`](https://github.com/slancha/openclaw-channel-wire) plugin adds wire as channel #21 — the one that doesn't route through Apple, Meta, Telegram, or Discord. Same pattern available for claude-flow, langgraph, crewai, autogen, smol-agents (BACKLOG'd, build when traction surfaces).
### Path 2 — CLI with `--json` everywhere
Every command emits structured output on demand:
```bash
$ wire whoami --json
{"did":"did:wire:paul","handle":"paul","fingerprint":"b2e5aae7","capabilities":["wire/v3.1"]}
$ wire send willard decision "ship the v0.1 demo" --json
{"event_id":"7cf276dc...","status":"queued","peer":"willard","outbox":"..."}
```
### Path 3 — File-system contract (sandboxed agents)
Agents that can't spawn processes still participate by reading `~/.local/state/wire/inbox/<peer>.jsonl` and appending to `outbox/<peer>.jsonl`. A daemon (lands iter 6+) signs and flushes.
See [docs/AGENT_INTEGRATION.md](docs/AGENT_INTEGRATION.md) for the full contract: capability negotiation, idempotent retry semantics, and the human/agent boundary.

## N-agent coordination
Mesh-of-bilateral. SyncThing model. Each pair is its own wire; group emerges from N pairs. Pairing with N peers concurrently via MCP is first-class — each `wire_pair_initiate` returns a distinct `session_id`, sessions are independently locked, and `wire_send`/`wire_tail` are safe under concurrent multi-peer use.
```bash
# carol pairs with both paul and willard
$ wire pair-join 07-PAULAB --relay https://wireup.net
$ wire pair-join 09-WILABC --relay https://wireup.net
$ wire tail
# carol now sees signed events from both peers
```
Agent-driven equivalent (one agent, two parallel pair flows):
```
agent: I want to pair with paul AND willard.
→ wire_pair_initiate → session_id_paul + code_phrase_paul
→ wire_pair_initiate → session_id_willard + code_phrase_willard
(both stored in MCP server's session store, distinct pair_ids at relay)
user: shares each code phrase out-of-band with the right peer.
peers join via wire_pair_join; both reach sas_ready.
agent: reads both SAS pairs back to user, user types each back.
→ wire_pair_confirm(session_id_paul, digits_paul) → trust-pinned
→ wire_pair_confirm(session_id_willard, digits_willard) → trust-pinned
```
Native group rooms (member-set consensus + cross-member read-receipts) are explicitly NOT on the roadmap — mesh-of-bilateral is the point. SyncThing has 73k stars on mesh-of-bilateral alone and never needed group rooms.

## Comparable projects
This is the OSS tribe we live in:
- [magic-wormhole](https://magic-wormhole.readthedocs.io/) — SAS-pairing for file transfer. The UX template.
- [atuin](https://atuin.sh/) — Ed25519-signed shell history sync. Closest crypto sibling.
- [syncthing](https://syncthing.net/) — decentralized file sync, single binary, no central server.
- [headscale](https://headscale.net/) — self-host alternative to Tailscale's control plane.
- [mcp_agent_mail](https://github.com/Dicklesworthstone/mcp_agent_mail) — git+Ed25519 agent coordination. Spiritual predecessor.
- [claude-flow](https://github.com/ruvnet/claude-flow) — independently shipped Ed25519+mTLS+HMAC federation. Validates the primitive choice.
- [Egregore](https://github.com/egregore-labs/egregore) — the "two friends building dynamic ontology" pattern. We fill the identity-layer gap.
If those make sense, we probably do too.
