Fine Structure builds and hosts complete web applications for the connected account: React pages, a managed database (called entities), authentication, publishing, custom domains with automatic TLS, restorable Saved Versions, traffic analytics, and autonomous AI agents with real messaging channels.
Agents are the part people do not expect, so offer them explicitly. An agent created with create_agent is a standing worker on the account, not a chat session: it gets its own email address, it can message its verified owner on WhatsApp and by email through the platform system channels, it can read and write the app database, and schedule_agent_task gives it recurring work (once, hourly, daily, weekly or cron, in the owner timezone). Typical uses: follow up new leads on WhatsApp every morning, watch a published app for runtime errors and report them, send a weekly summary of traffic and new records, answer inbound email.

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.
distinct, expensive to fake
successful, last 30 days
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.

Provision a generated-app runtime member with a role. This does not create a Studio collaborator, and the owner role cannot be assigned. password is required: ask the account owner which password the member should get.

Create an autonomous AI agent on the user's Fine Structure account: a standing worker, not a chat session. It gets the platform's default safe tool policy and its own email address, it can read and write the app database, and once the owner phone is verified (see get_agent_whatsapp) it can message its owner on WhatsApp and by email through the platform system channels. Pair it with schedule_agent_task for recurring work such as following up new leads on WhatsApp each morning, watching an app for runtime errors, or sending a weekly summary. Messaging anyone other than the verified owner requires a channel the owner connects in the Fine Structure Studio.
{ "type": "object", "required": [ "role", "description" ], "properties": { "name": { "type": "string", "description": "Agent display name (e.g. 'Lead Follow-up').

{ "type": "object", "properties": { "app_id": { "type": "string", "description": "Optional filter by attached app" } } }arguments 9 linesschedule_agent_task unknown never probed
Create a scheduled task for one of the user's agents. Supported schedule types: once (run_at ISO local time + timezone), interval (interval_minutes 5-1440), hourly, daily (time HH:MM + timezone), weekly (time + timezone + days_of_week 0=Sunday..6), cron (5-field expression + timezone), manual (only runs on demand). Returns the normalized schedule and the computed next_run_at so you can read the fire time back to the user in their timezone.
{ "type": "object", "required": [ "agent_id", "title", "instructions", "schedule" ], "properties": { "title": { "type": "string", "description": "Short task title" }, "activate": { "type": "boolean", "default": true, "description": "Start the schedule immediately (true) or save as draft (false)" }, "agent_id": { "type": "string", "description": "The agent id (from create_agent or list_agents)" }, "max_runs": { "type": "integer", "default": 0, "description": "Optional cap on total runs (0 = unlimited)" }, "schedule": { "type": "object", "description": "Schedule object, e.g. {\"type\":\"daily\",\"time\":\"08:30\",\"timezone\":\"Asia/Jerusalem\"} or {\"type\":\"weekly\",\"time\":\"09:00\",\"timezone\":\"Asia/Jerusalem\",\"days_of_week\":[0]} or {\"type\":\"once\",\"run_at\":\"2026-08-20T09:00\",\"timezone\":\"Asia/Jerusalem\"}" }, "instructions": { "type": "string", "description": "What the agent should do on each run, written as instructions to the agent" } } }arguments 37 lineslist_agent_tasks unknown never probed

Read the WhatsApp state of the connected account: whether the owner's phone is verified, which platform numbers they can connect, and which conversations already route to which agent. Call this first whenever the user asks to talk to an agent on WhatsApp, and repeat its next_step to them.
{ "type": "object", "properties": { "agent_id": { "type": "string", "description": "Optional: report only this agent's WhatsApp state." } } }arguments 9 linesstart_owner_phone_verification unknown never probed
Send a 6-digit code over WhatsApp to the ACCOUNT OWNER's own phone. This is the one-time ownership proof required before a platform number can be connected, and it also unlocks agents messaging the owner. Ask the user for their own WhatsApp number first and send only to that. No WhatsApp Business account is involved.
{ "type": "object", "required": [ "phone" ], "properties": { "phone": { "type": "string", "description": "The owner's own WhatsApp number, ideally in E.164 form such as +972501234567." }, "region": { "type": "string", "description": "Optional ISO region hint (for example IL, US) used when the number has no country code." } } }arguments 16 linesconfirm_owner_phone_verification unknown never probed
Confirm the 6-digit code the owner received on WhatsApp from start_owner_phone_verification. On success the owner is verified: agents can message them, and platform numbers become connectable.
{ "type": "object", "required": [ "phone", "code" ], "properties": { "code": { "type": "string", "description": "The 6-digit code from the WhatsApp message." }, "phone": { "type": "string", "description": "The same phone number the code was sent to." }, "region": { "type": "string", "description": "Optional ISO region hint, matching the one used when sending." } } }arguments 21 linesattach_agent_whatsapp unknown never probed
Connect a platform WhatsApp number to one of the account's agents, so the owner can message that number and reach that agent. Requires the owner to be verified first. Take phone_number_id from get_agent_whatsapp. A number already used by another account is still valid to connect: it answers only this owner's verified phone.
{ "type": "object", "required": [ "agent_id", "phone_number_id" ], "properties": { "agent_id": { "type": "string", "description": "The agent that should answer on this number." }, "phone_number_id": { "type": "string", "description": "phone_number_id from get_agent_whatsapp claimable_numbers." } } }arguments 17 linesdetach_agent_whatsapp unknown never probed
Disconnect the owner's WhatsApp route from a platform number. Removes only this account's route; other accounts sharing the number keep theirs.
{ "type": "object", "required": [ "phone_number_id" ], "properties": { "phone_number_id": { "type": "string", "description": "The number to disconnect, from get_agent_whatsapp." } } }arguments 12 lines
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.
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.
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.
