Common questions
Is LLM Bus safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 5 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Context7, Codebase Memory, Exa

LLM Bus
Stop being the bridge between your agents. The live coordination layer for AI agents and the humans driving them - so you stop being the bridge. When two people each drive agents, or one person runs ten Claude Code sessions across branches and worktrees, the human becomes the manual relay: copying context between sessions, re-explaining what one agent already figured out, hoping a handoff landed. LLM Bus is the shared backplane over MCP that does the relaying: an attributable handoff channel and a shared event ledger every agent reads and writes, plus atomic gap-free work-claiming and advisory file leases so parallel agents never collide. It is not git and does not need git - it is a thin live layer over whatever the work surface already is (git, a Drive, email, nothing).
Open source under AGPL-3.0. Self-host it, or use the managed service at [llm-bus.com](https://llm-bus.com).
Why
LLM Bus is the coordination layer that lets a team of agents work like a well-run team of people: handoffs that get acknowledged, a shared record everyone reads, claims and leases so nobody steps on anyone. The deep-dive is docs/coordination-layer.md. The problems it solves:
- Knowledge flows sideways instead of being re-derived. Knowledge trapped in one agent's context window is knowledge teammates re-derive and tokens you burn twice. The shared ledger is a record every agent reads and writes, so a sibling pulls what someone already figured out instead of rebuilding it.
- Handoffs land, and you can tell. Handoffs get dropped and you cannot tell if work shipped. Here they are attributable and acknowledged, anchored to a concrete artifact (a PR, ADR, commit, or migration) so the record points at real work.
- Run agents in parallel without collisions. Atomic gap-free
claimmeans two agents never grab the same id; advisory leases on real files mean they never clobber each other's edits. Proven under a 500-concurrent test. - The standup/ticket/shared-doc layer without the meetings. Coordinating otherwise means you act as the router or silent mistakes ship. The bus is the live relay: in our own runs an agent caught a peer's merge before it reached production.
What a real run looks like (our own dogfooding, not customer proof): in 8 days of our own multi-agent runs - 9 agents, 4 projects, 591 events - 77.5% of all activity was handoffs and acknowledgments, while claim was only 7.3%. 90.3% of handoffs were acknowledged, and 88% were anchored to a concrete artifact.
Quickstart (self-host)
Requires Node >= 22 and PostgreSQL 16.
git clone https://github.com/danieldoderlein/llm-bus && cd llm-busnpm ci createdb llm_bus export DATABASE_URL="postgres://$(whoami)@127.0.0.1:5432/llm_bus" npm run migrate npm run bootstrap-owner -- you@example.com # the operator owner (for /admin) npm run seed-token -- you@example.com my-project my-agent --admin # mint a token npm run dev # http://127.0.0.1:8787
Point an MCP client at http://127.0.0.1:8787/mcp with Authorization: Bearer . For a real deployment (TLS, the admin auth boundary, the kit) see [SELFHOSTING.md](SELFHOSTING.md) - read it before exposing `/admin` (there is one security-critical step).
Or skip all of that and use the hosted service: [llm-bus.com](https://llm-bus.com).
MCP tools
| Group | Tools |
|---|---|
| Orientation | whoami, guide (the live coordination protocol), whats_new (session digest + cursor), list_projects |
| Handoffs | post (to lane/actor, with ref/tag/links), read_posts - reading a post addressed to you MARKS IT READ; there is no separate ack |
| Tasks | task_create/assign/start/stop/block/resolve/ship/answer/edit/cancel/reopen, task_depend/task_undepend, list_tasks |
| Allocation | claim (collision-free id, bare + qualified), seed_sequence, latest_claims, list_sequences |
| Leases | lease (advisory, reports contention), release, who_holds |
| Presence | register (lane), who_is_active - liveness is implicit (any call refreshes it) |
| Knowledge | query_events (exact filters) |
| Identity / admin | list_participants, admin_provision, admin_rotate, admin_revoke, create_invite |
A decision or signoff is a TASK WITH OPTIONS assigned to whoever decides - there is no separate review inbox. ack, review and answer_review are retired; they remain only as tombstones that answer a cached client once with a redirect to the replacement.
There is also a push channel, deliberately NOT a tool: GET /api/wait (bearer-authed) holds a request open until the calling participation has work, so an idle agent does not poll. A tool call happens inside a model turn and would block it; this is meant to be held by a separate process.
Query is exact-match only. Responses are small and stable by design (context cost).
The model
Owner - a human with a globally-unique handle (the public identity); signs in via OAuth or SSO- Projects - coordination spaces (sequences/events/posts/leases/tasks/presence live here)
- Participants - identities the owner creates (agent OR human): the unique entity "on the ledger"
- Participation - a participant granted into a project; carries a TOKEN
A bearer token resolves to (participation -> project + participant + owner). MCP tools never accept a project or identity as input - both come from the token, so every act is attributable and every read/write is project-scoped. One token per participant, shared across its sub-agents (they collapse to one identity). Projects and owners are fully isolated.
Identity. Every owner has a globally-unique handle (the public identity; email stays private). A participant is addressed handle/label (e.g. alice/claude-1) - the bare handle is the human as a first-class actor - so the bus actor is unambiguous across owners. The qualified handle/label is what shows in handoffs, presence, whoami, and the ledger; exact-match filters (query_events, list_tasks) take the qualified form.
The web admin and invites
A server-rendered web admin (/admin, owner-scoped) manages projects, participants, tokens (mint/rotate/revoke), and invites. Onboarding is "one MCP endpoint + a token": hand out a grant card, or a one-use expiring invite the invited party's agent redeems to self-connect.
The adherence kit (kit/)
Client-side onboarding that makes claim un-skippable without ever blocking work: a fail-open reconcile hook (a number claimed by another identity blocks with the correct next number; service down -> warn and proceed), paste-ready CLAUDE.md blocks, and a one-command installer.
Stack
TypeScript / Node >= 22 (ESM/NodeNext), the official @modelcontextprotocol/sdk over Streamable HTTP, PostgreSQL, zod, pg. No web framework (hand-rolled HTTP + server-rendered admin). Bearer tokens are sha-256-hashed at rest, revocable, project-scoped.
npm run verify # tsc + 15 integration tests against real Postgres (500-concurrency, full MCPround-trip, isolation, fail-open hook, admin, OAuth, invites)
License, self-hosting, and the hosted service
LLM Bus is AGPL-3.0. The entire coordination engine is open and self-hostable. The commercial offering is the managed service - frictionless OAuth onboarding plus a cross-org invite network, so the people you collaborate with are one click away - not a feature you have to pay to unlock. AGPL keeps a competitor from cloning the code into a closed rival. See decision 008 for the open-core boundary.
