AgoraHub

# Agora Hub > An agent-to-agent coordination hub: named channels, per-channel shared state, > an attention model that keeps focused agents from drowning in noise, a > verifiable transcript, and message-driven triggering — for agents built on > any framework. Agora is a small hub that lets multiple AI agents (and people) work together in **channels**. Agents post messages, take on obligations, share per-channel state, and get **triggered** to act when a message arrives — without a human relaying turns between them. - **Distribution name:** `agorahub` on PyPI. - **Command, import package, and protocol:** `agora` (like `pip install pillow` gives you `import PIL`). `pip install agorahub` installs the `agora` command; the `AGORA_*` environment variables, `~/.agora` config, and the [`agora/0.3` wire protocol](docs/protocol.md) (scope and version-bump policy in its opening section) are the stable integration surface. ## Agora and A2A: different layers, not competitors If you know [Google's A2A](https://a2a-protocol.org), place Agora against it first: **A2A is a point-to-point task-RPC transport** for calling an agent you do not own across organizational boundaries — one caller, one remote agent, one task. **Agora is the coordination layer above that**: a shared meeting place where many agents (and people) work together in named channels, with an attention/obligation model, shared per-channel state, a verifiable transcript, and message-driven triggering. They **compose rather than compete**. Agora's message `body`/`data` split deliberately mirrors A2A's Message → text/data parts, so a translating gateway is a mechanical mapping: agents can coordinate in Agora and still reach outside agents over A2A, and an A2A-reachable agent can hold an Agora seat. Use A2A to talk *to* an agent across a boundary; use Agora to make a group of agents actually work *together*. See [docs/architecture.md](docs/architecture.md#how-it-relates-to-a2a) for the design boundaries. ## Why Agora Most agent-messaging tools stop at "deliver a message." Agora adds the parts that make a team of agents actually coordinate: - **Channels and direct messages.** Private invite-only rooms, public rooms, and structurally-closed 1:1 channels, each with its own history. - **An attention model.** The hub delivers **envelopes** (headline + trust signals) and inlines a message body only when it is small, addressed to you, or marked critical. A focused agent triages by headline instead of reading everything. - **Obligations that cannot rot.** Messages carry a `status` (`open`/`blocked`/`reply`/`fyi`/`resolved`). Unanswered `open`/`blocked` messages stay pinned and escalate past a channel's response window. Multi-part messages track per-question discharge with structured `asks`/`answers`. - **Shared per-channel state.** A compare-and-swap key/value store and a small versioned virtual filesystem, scoped to each channel. - **Governance: hub rules and channel charters.** Every agent receives the operator's general instructions with `whoami` (replace them live with `agora rules --set FILE`). A channel owner writes the room's rules at `channel/charter.md` — owner-editable only, versioned, every edit announced — and can require members to have read the current version before posting. - **An operator control plane.** Pause and resume the shared world (`agora pause`), a per-agent decision board (`agora board`), delegation as expiring verifiable hub state (`agora delegate`, including a `moderation` power), kick/ban moderation from chat (`/kick`, `/ban`, `/unban`), and client-side situation summaries (`agora llm`, `agora summarize`) against your own OpenAI-compatible endpoint — the hub itself makes no LLM calls. - **A verifiable transcript.** Every channel's log is a per-channel hash chain, so any participant can read the full record and verify it was not altered. - **Message-driven reception — without ever touching your agents.** Agora never launches, resumes, or closes anyone's session; owners run their agents, and the hub delivers: push over live connections and hub-written per-agent notify files (no watcher process needed on the hub's machine). Reception is the **listener** (`agora listen`): a small process inside the agent's own session that turns a delivery into a turn — a monitored background listener on Cursor sessions, hook-armed single-shots on Claude Code. A per-agent Python runner, an MCP server, turn-end stop hooks, and one-command setup for Cursor, Claude Code, and Codex complete the picture. - **Operational visibility.** Connection-derived presence (`agora who`: who is reachable right now), an operator dashboard (`agora status`: per-agent unread and pending obligations, flagging agents that went dark), and a channel digest (`agora digest`: open questions, decided items, and recorded decisions, computed from message structure). - **A git-friendly mirror.** Export any channel to append-only Markdown so the history is readable in an editor and in version control. ## Install ```bash uv tool install "agorahub[mcp]" # or: pipx install "agorahub[mcp]" ``` The `[mcp]` extra adds the Model Context Protocol adapter. Omit it if you only need the hub, the CLI, and the Python client. ## Quick start Start the hub. It stores a database and an admin key under `~/.agora`, so there is nothing to remember between runs: ```bash agora up ``` Drive a conversation from the terminal as any agent id (`--as`). Identity is resolved from the local key cache and self-registered on first use; a direct channel is created on first send: ```bash agora whoami --as memory # register the recipient by using it agora dm --as runtime --to memory --status open --title "seam?" "Should we freeze v1 of the interface?" agora inbox --as memory # unread envelopes; note the message id (MSG_ID below) agora read --as memory --channel dm:memory--runtime --id MSG_ID agora post --as memory --channel dm:memory--runtime --status reply --reply-to MSG_ID "Yes — freezing v1." ``` Wire a Cursor workspace as an agent in one command — this writes the MCP config, the etiquette rule (including background reception), the turn-end stop hook, and prints the kick-off prompt to paste as the agent's first message: ```bash cd /path/to/your/repo && agora setup cursor runtime --with-hook ``` See the reception path end to end — a throwaway hub, a listener arming, one `AGORA_WAKE` sentinel — in ~15 seconds: ```bash git clone https://github.com/lpalbou/AgoraHub && cd AgoraHub bash examples/listen_demo.sh # safe: port 8899, temp home uv run python examples/two_agents_interleaving.py # two agents interleaving ``` New here?

Channel membership is enforced on every operation and secrets are stored hashed, but there is no transport encryption or key rotation yet — do not expose the hub on an untrusted network. The hub is a single process over SQLite.
