Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Beschreibung vom Entwickler (englisches Original)
Hand work between AI agents across devices and vendors: one-shot links or an E2EE channel.
Diese drei werden nie zu einer Punktzahl zusammengefasst: Meinungen, Messungen und Beliebtheit sind verschiedene Dinge.
Für diesen Server haben wir noch keine Zusammenfassung in einfacher Sprache geschrieben. Unten stehen die Fakten, die wir aus der Registry gelesen haben.

Tool-Namen und -Beschreibungen genau so, wie der Server sie am 7. Nov. 2026 gemeldet hat. Geschrieben hat sie der Entwickler, nicht wir; wir zeigen sie als reinen Text.
handoff_putStore a piece of context and get back a short code. The person gives the link handover.tools/ to an agent on another device and it can fetch the content — no copy-paste of long text. The code is 8 letters, easy to type on a phone. NOT ENCRYPTED: the server can read what you store
handoff_getFetch content stored by handoff_put using its 8-character code. The code is case-insensitive and hyphens are ignored, so 'kvmtrhxp' and 'KVMT-RHXP' are the same; the person may give it as a link like handover.tools/kvmtrhxp, and passing that is fine too. Return the content to the
handoff_revokeDestroy content stored by handoff_put right now, before its TTL runs out and whether or not it has been fetched. Requires the revoke_key returned by handoff_put — the person fetching with the short code cannot revoke, only the writer can. Use this the moment someone says they sen
channel_openStart pairing two agents on different machines for a multi-round exchange (e.g. one explores, the other studies and asks follow-up questions). Use the local client at https://handover.tools/client/channel.py — do not call this by hand. The client generates a secret password local
channel_joinSecond half of pairing, run by the local client at https://handover.tools/client/channel.py. Send only the first 3 characters of the spoken code (the nameplate) plus this side's SPAKE2 message; the other 5 characters are the password and must never be sent to the server. The name
channel_sendRelay one ciphertext to the other side of a paired channel. The ciphertext must come from the local client at https://handover.tools/client/channel.py; do not call this by hand, and never base64-encode plaintext into it (that is rejected). Only send after the person has seen and
channel_fetchUse the local client at https://handover.tools/client/channel.py rather than calling this by hand: it returns ciphertext only the client can decrypt. Returns the peer's messages this side has not fetched yet. Call only when the person asks. Clients fetch with peek=true, which mar
channel_ackUse the local client at https://handover.tools/client/channel.py rather than calling this by hand. After a fetch with peek=true, the client calls this with the highest sequence number it processed. That is what the peer sees as read, so a response lost in transit never turns into
channel_closeEither side can close. Deletes the channel, both keys, and every stored message immediately. The other side's next fetch reports not_found_or_closed.

One agent writes it, another agent reads it. You only carry an 8-letter link between them.
handover.tools moves a piece of work from one AI agent to another: across devices, across vendors, or to another person. Brainstorm with the agent on your phone, then say "hand this over with handover.tools". Paste the link it gives you (handover.tools/kvmtrhxp) into Claude Code on your laptop, and that agent picks the work up where your documents already are.
Bring the idea to your context, not your context to the idea.
There is no account and nothing to install. Any agent that can open a web page can use it.
| One-shot | Channel | |
|---|---|---|
| Use it for | Handing over one piece of text | Several rounds between two agents |
| Encryption | None. The server can read it, so don't put secrets in it | End-to-end (SPAKE2 + ChaCha20-Poly1305). The server only ever stores ciphertext |
| Lifetime | Gone after the first read, or after 60 minutes (24 h max) | Until either side closes it |
| What the agent needs | Can open a URL, or has MCP | Can run a Python script (uv run) |
| Who decides | The person carries the link | The person approves every send and starts every fetch |
curl -X POST https://handover.tools/api/handoff/put \
-H 'Content-Type: application/json' \ -d '{"content":"...","label":"notes"}' # → {"code":"kvmtrhxp", "revoke_key":"...", ...} curl "https://handover.tools/api/handoff/get?code=kvmtrhxp"
Opening handover.tools/ doesn't use up the code. That URL returns instructions, and the actual read is a second request. Link previews in Slack or iMessage therefore don't burn the content before the recipient sees it.
curl -so ~/.handoff/channel.py --create-dirs https://handover.tools/client/channel.py
uv run ~/.handoff/channel.py open --name study --brief "..." # machine A: prints a code uv run ~/.handoff/channel.py join kvmtrhxp --name study # machine B uv run ~/.handoff/channel.py send --name study --kind question --file q.md uv run ~/.handoff/channel.py fetch --name study
The 8 letters are a 3-letter nameplate, which the server sees and uses to find the channel, plus a 5-letter password that is generated on machine A and never uploaded. The password goes into SPAKE2, the same construction magic-wormhole uses. The server never learns the password, so it cannot impersonate either side. /client/channel.py is served from client/channel.py, and its sha256 is published at /api/discover, so you can check that the client you downloaded matches this repository.
The threat model, including what we *don't* claim, is at handover.tools/security.

| Document | What it covers |
|---|---|
| docs/system-design.md | Architecture: components, request pipeline, data model, flows, trust boundaries, limits and capacity, failure modes, known gaps |
| docs/spec/handoff.md | The one-shot contract: operations, code format and normalization, atomicity, code links, limits |
| docs/spec/channel.md | The channel protocol: pairing, SPAKE2 parameters, key schedule, wire format, receiver rules, server API, lifecycle. Detailed enough to write a second client |
| docs/decisions.md | Why it is built this way: what was tried, what was rejected, and what broke |
| CHANGELOG.md | What changed, newest first. Also at handover.tools/changelog |
The specs are the contract. A behavior change starts in the spec, then the code and tests follow.
Requires Node ≥ 22 and Python 3.12.

Issues and pull requests are welcome. AGENTS.md has the working rules, for people and coding agents alike: a change in behavior starts with the spec in docs/spec/, then the code and the tests. Report vulnerabilities privately: see SECURITY.md.
