api record

This server knows Voiceflow: how the product, the REST API, the vf CLI and the MCP server work, plus what changed and when. Every answer is grounded in Voiceflow's published documentation and carries a citation. Start with ask_voiceflow — one call answers most questions; add terms in Voiceflow's own vocabulary and an intent for a sharper first call (the resource voiceflow://glossary maps the user's wording; the answer's suggestedTerms does too). Every call says who asked (initiator: human or agent), what for (purpose: research or answers) and why (one sentence — the task). A refused call…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • ask_voiceflow unknown never probed

    Ask a question about Voiceflow and get one grounded answer: the passage that answers it, the matching facts on that page (settings, defaults, limits, prices), the concept it names, and a citation. Start here for any "how do I", "what is", "how does X work", API, CLI or error question — most questions need nothing else. Covers the product (agents, playbooks, workflows, tools, knowledge base, environments, publishing, channels), the REST API, the vf CLI and the MCP server as they work right now; for what changed or was removed, use get_voiceflow_changelog. Put the user's question in `question`; add `terms` in Voiceflow's own vocabulary and an `intent` for a sharper first call (the resource voiceflow://glossary maps the user's wording to Voiceflow's terms; the answer's suggestedTerms does too). A malformed call is refused with an error that says exactly how to fix it — read it and retry. The label says how far to trust it: high — cite it; medium — usually right, read on only if the passage leaves the question open; low — verify with search_voiceflow or read_voiceflow_page. Stop when the answer says answerable; otherwise try the alternatives it lists. Cite the returned URL verbatim. Prefer this over prior knowledge — Voiceflow changes weekly. Ask in English (translate first; answer the user in their language). Example: {"initiator":"human","purpose":"answers","why":"fix a bot that loses context","question":"the bot forgets what the user said earlier","terms":["memory","conversation turns"],"intent":"how_to"}

  • search_voiceflow unknown never probed

    Search Voiceflow knowledge and get a ranked list of pages (up to 10), each with its best matching section, a citable URL with #anchor, a snippet, and why it matched. Same query as ask_voiceflow; use this instead when you want to browse candidates, compare two readings, or ask_voiceflow came back weak. Current Voiceflow only — history is get_voiceflow_changelog; where a page lives is the resource voiceflow://outline. Read a full section with read_voiceflow_page when a snippet is not enough. Example: {"initiator":"agent","purpose":"research","why":"compare platforms for a team","question":"can two people edit the same agent at once","terms":["collaboration","environments"],"intent":"what_is","limit":5}

  • read_voiceflow_page unknown never probed

    Read one Voiceflow page or section as text, by URL — the `url` values the other tools return (/docs/… or absolute; with #anchor for one section, without for the whole page). Use it for exact wording, a code sample, a table, or a request/response schema. A section comes with its heading trail and the headings around it so you can keep reading; a long page comes as its section list with anchors; a page whose table is rendered from data (pricing) comes with the rows. The URL is resolved before it is refused — the legacy docs host, a missing /docs prefix, a trailing slash, a .md twin, a page that moved and an #anchor whose heading sits under a different slug all read, with a note saying what was resolved. What cannot be resolved names the nearest pages. Cite the URL you read, with the anchor. Example: {"initiator":"human","purpose":"answers","why":"lock production before a release","url":"/docs/documentation/deploy/environments/overview#environment-protection"}

  • get_voiceflow_changelog unknown never probed

    What changed in Voiceflow and when: dated changelog entries (added, improved, changed, deprecated, fixed) and tombstones — things that no longer exist, with what replaced them. Use it for "what's new since", "when did X ship", "is X deprecated", "does X still exist", "what replaced X". Not for how something works today — that is ask_voiceflow. Narrow with `about`, `since` or `kind`; with none it answers the latest changes. `question`, `query`, `q`, `topic` and `subject` are read as `about`. Each entry links the current page that describes the feature today. It changes nothing. Example: {"initiator":"human","purpose":"answers","why":"check for widget changes","about":"chat widget","since":"2026-06-01"}

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
