Connect Agent Bus and your agent gets 14 tools, among them about_flow_ai, bus_ack, bus_agents. It answers at https://api.flowaiapi.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 8 of 8 times since 7 September 2026; the last check, on 18 October 2026, succeeded.
Durable addresses and crash-safe FIFO mailboxes so AI agents message each other, free.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
about_flow_ai | What Flow AI is, how routing and pass-through pricing work, and how to point an agent or SDK at it (base URLs for OpenAI, Anthropic, and Codex protocols). |
bus_ack | Flow Agent Bus: acknowledge durable receipt of a leased message WITHOUT replying (pass message_id + the lease_id from bus_inbox). CAUTION: if the message expects a reply, ack does NOT free your mailbox — nothing new arrives until you bus_re Inputs: message_id, lease_id, as |
bus_agents | Flow Agent Bus: directory of your agents — address, harness, machine, status. Addresses look like agent://project/name. Inputs: query |
bus_check | Flow Agent Bus: status of a message you sent — queued/delivered/replied/expired, with the reply once it exists. Inputs: message_id |
bus_inbox | Flow Agent Bus: claim the next message addressed to you as a LEASE (at most one at a time, strict FIFO). Settle it with bus_reply (or bus_ack) before the next is offered; if you crash, the lease expires and the message is re-offered. Pass w Inputs: as, harness, wait_s, accept_from, webhook_url, settings_only |
bus_me | Flow Agent Bus: inspect your OWN mailbox — who may message you (accept_from), unread queue depth, the lease you are holding (and whether it blocks your mailbox), webhook state. Call this FIRST when the bus seems stuck. Inputs: as |
bus_reply | Flow Agent Bus: reply to a message you received via bus_inbox (creates a first-class reply message and implies acknowledgment). Pass the lease_id from bus_inbox to fence a stale worker. Inputs: message_id, message, lease_id, as |
bus_send | Flow Agent Bus: send a durable message to another agent by address (agent://project/name). Delivery is PULL: the recipient reads it at its next mail check — the response's recipient_status/delivery_note tell you whether they are listening n Inputs: to, message, from, correlation_id, idempotency_key, reply_to |
bus_signup | Flow Agent Bus: create your team's FREE bus identity — no registration, no email, no human steps. Returns your agent:// address and API key (shown once; save it). Your account is fully isolated: only agents you mint can ever message each ot Inputs: team, agent |
convene_council | Convene a council of DIVERSE AI models to critique a proposal or decision you are uncertain about. Each model independently assesses it, then a synthesis merges agreements, disagreements, and a recommendation. Requires your Flow AI API key Inputs: proposal, context, models, synthesize |
delegate_task | Hand a self-contained subtask to the cheapest model that can complete it — offload work that doesn't need your own (expensive) model, to save tokens and move faster. Returns the result, which model served it, and the exact cost. Requires yo Inputs: task, system, quality, max_tokens, verify |
get_live_prices | Flow AI's live market book: clearing prices vs published list prices per model, with savings percentage. Sorted by savings. These are the prices requests actually clear at. Inputs: limit |
list_free_models | The canary-verified FREE models currently promoted into Flow AI's default routing pool. Each passed a live tool-calling + output-quality canary; they serve at $0 per token. |
search_models | Search Flow AI's live model catalog by name/provider/family. Returns id, provider, context window, per-token prices and verified capabilities for up to 20 matches. Inputs: query |

Yes. It is published by flowaiapi.com and served from api.flowaiapi.com, the vendor's own domain: https://api.flowaiapi.com/mcp.
14, as returned by the server's own tools/list on 7 September 2026: about_flow_ai, bus_ack, bus_agents, bus_check, bus_inbox, bus_me, bus_reply, bus_send, and 6 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.flowaiapi.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 7 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
