What it can do
| Tool | What it says it does |
|---|---|
ask_finai | Hand a task in words to Finai, Final's own AI agent, and get its finished answer. It runs as this connection's user on its company, within the allowed packs, and uses Final's tools itself (looking records up, creating products, building or deploying an app). Use it for multi-step merchant jobs you… |
call_tool | Run a read-only tool from any allowed pack by its full name (for example hub_find_low_stock) without it being listed. Only tools that read are accepted; tools that change data run through call_write_tool. Arguments follow that tool's own input schema, which find_tools returns. |
call_write_tool | Run a tool that creates, changes, deletes, sends or deploys from any allowed pack by its full name (for example hub_update_product) without it being listed. Only tools find_tools marks as writes are accepted; read-only tools run through call_tool. Arguments follow that tool's own input schema… |
disable_packs | Remove packs from tools/list for this connection to keep the list short. Tools stay reachable through call_tool and call_write_tool. |
enable_packs | Add packs to tools/list for this connection (remembered). Only allowed packs can be listed; the client refreshes its tool list. |
find_tools | Search every allowed pack for tools by what you want to do ("low stock", "create a product", "deploy the app"). Returns matching tool names with their pack, whether they are listed and whether they change data. Run a read-only match with call_tool and a write with call_write_tool, or enable_packs… |
flow_apply_blueprint_widgets | COPY vetted blueprint widgets into a flow as real files — byte-exact, no transcription. Pass picks of { blueprintId, widgetId } (from list_blueprints / search_blueprints); the widget files land under src/widgets/<blueprint>/ with their command-frame plumbing intact, persisted as a restorable… |
flow_apply_upstream_update | Apply the update reviewed with get_upstream_update. Pass resolutions: exactly one entry per conflict — { path, contents } with the COMPLETE merged file, or { path, delete: true } when the file should not exist. Missing, unknown or ambiguous entries fail the whole call with nothing written (the… |
flow_connect_chat | Attach this agent session to an EXISTING flow as a chat in the builder's rail (so the flow's owner sees your work alongside their own chats). Also use log_message to narrate what you're doing. |
flow_create_custom_table | Create a new custom data table (schema: name + typed columns) in your Final organization. USE THIS for any data the app must keep — loyalty stamps, waitlists, bookings, inventory logs, settings: the platform syncs the table to every station running the flow and keeps it working offline at the POS… |
flow_create_flow | Create a new, empty flow (app build) in your Final organization for YOU to write the app into. It appears in the Miami builder immediately, with this agent session attached as a chat. Optional theme knobs seed the live palette. Optional `device` ("mobile", "kiosk", "iphone", …) sets the preview… |
flow_create_flow_from_blueprint | Create a NEW flow that starts as a complete, vetted application rather than an empty file tree — the fastest path to a working build when an FBB (a Final Business Blueprint: a whole app) matches what the user wants. For an app the user merely DESCRIBED, use start_build (the website's own start… |
flow_delete_flow_files | Remove files from a flow's tree by path. Engine-owned paths are rejected. Recorded as a checkpoint + chat note like writes. |
flow_deploy_flow | Direct deploy for CI/agent workflows: builds the app in a server sandbox (npm install + vite build) and publishes the dist to Final web-hosting as a new live version. Two things stop a deploy: a failing build, and a hardcoded credential (a build is distributable to other companies, so a baked-in… |
flow_get_blueprint | INSPECTION ONLY — read a blueprint's overlay code by id (from list_blueprints) to understand how it works. To USE a blueprint, apply it: apply_blueprint_widgets for a widget-set (materializes its widgets byte-exact with the command-frame plumbing intact AND provisions the custom tables its code… |
flow_get_preview_status | Authoritative server-side health probe of the flow's preview sandbox, plus a short snapshot of recent dev-server logs (useful to diagnose a red screen or crash). |
flow_get_scaffold | The contract every Final flow app is built against: which files the ENGINE owns (never write them — they are re-asserted verbatim), the baseline package.json (Vite + React 19 + TS + Tailwind + command-frame), the rules your files must follow, and the runtime contracts that compile and preview fine… |
flow_get_upstream_status | Has the build this flow was copied from released a newer version? Covers both a "Make it yours" clone of a listing and a build started from an FBB. Returns update.status: "available" (a newer deployed release exists — review it with get_upstream_update), "current" (up to date), "unknown" (the… |
flow_get_upstream_update | Review what an update from the original build would change — the same review the builder shows its maker, shaped for an agent. Returns the releases since the clone, the clean changes (added/changed/removed paths, with full incoming contents for added+changed), and CONFLICTS: files where this… |
flow_install_extension | Install an extension ORG-WIDE: creates the install link on EVERY company in your Final organization (demo companies included), skipping companies that already have it, so it is safe to retry. Installing is deliberate and org-visible — confirm with your user and call this ONLY when they explicitly… |
flow_list_blueprints | List EVERY vetted, type-checked blueprint available to reuse — working functionality (gift cards, loyalty, payment surfaces, product grids, carts, customer views, order tickets, receipts), not just screen layouts. Check the catalog BEFORE creating custom tables or hand-rolling a capability… |
flow_list_custom_tables | List your organization's custom data tables with their column schemas. Custom tables are Final's built-in, station-syncing database — data written on one station is automatically synced to every other station running the flow, and keeps working OFFLINE at the point of sale. They are the ONLY… |
flow_list_extension_custom_tables | List the CUSTOM TABLES an extension registers (table name + typed columns), so generated code can read/write its data at runtime via renderClient.getCustomTableData / upsertCustomTableData by table name (ground the calls with lookup_command_frame). Only the org's OWN extensions expose their tables… |
flow_list_extension_surfaces | List the SURFACES an extension exposes — embeddable iframe injection points, each with a surfaceId, a platform (builder/hub/render), a type, and a url. Render an installed surface inside a generated screen with the engine component `<ExtensionSurface surfaceId="<surfaceId>" />` (ground it with… |
flow_list_extensions | List the platform EXTENSIONS available to your organization — the org's own plus the public marketplace — so you can suggest, inspect, or install one. Each entry carries an id, label, category, short description, and its source (organization or public); public results need no hub credential, and a… |
flow_list_flows | List the flows (app builds) in your organization, newest first: id, title, timestamps, and live theme knobs. Final staff sessions also see Final's own flows, marked owner: "Final". Use a flow id with the other tools, or create_flow to start fresh. Clones of listed builds carry an upstreamUpdate… |
flow_list_secret_keys | List the key NAMES already stored in your organization's encrypted secrets vault — never the values (no tool returns a secret value). Use this to (a) reuse an existing key instead of requesting a new one, and (b) poll whether a request_secret ask has been fulfilled by the human. Generated code… |
flow_log_message | Record a message in this agent's chat inside the builder — the user's request (role 'user') or your own progress/summary (role 'assistant'). Keeps the builder timeline faithful to what happened in this session. |
flow_lookup_command_frame | Look up the EXACT, version-locked command-frame API a generated Final POS app runs on: renderClient method signatures + params, CF* entity field lists, pub/sub topic event vocabularies, and worked examples. Pass one of method/entity/topic for a precise lookup, entity+field to confirm a field… |
flow_lookup_engine_component | Look up the exact props/signature of an engine-owned `./final/*` helper: the `@/final/ui` primitives (Button, IconButton, Card, Tile, Input, Field, Chip, ListRow, Dialog, Sheet, Toolbar, Heading, EmptyState, cn) plus usePrint, StationHomeButton, SwitchUserButton, useStationHome, Barcode… |
flow_lookup_pos_api | Look up the Final POS REST API (https://api.finalpos.com) — endpoint method/path, request fields, response shape, and a worked fetch example. This is the ONLINE-ONLY fallback for admin/management operations command-frame cannot express (creating products/variants/categories, customer management… |
flow_open_in_builder | The recommended way to finish: a deep link that opens this flow in the Miami builder, where the owner can review the work, restore checkpoints, and deploy through the Launch tool (validation gates, listing media, changelog, version history). |
flow_read_flow_files | Read a flow's generated source tree. Omit `paths` to list all file paths (cheap); pass `paths` to fetch specific files' contents. |
flow_rename_flow | Rename a build (flow) authoritatively across the platform in one call: the builder header, list_flows / open_in_builder, and the Deerlake catalog all reflect the new title, and updatedAt is bumped. A deployed build keeps its hosted web app: the hostname and version history are unchanged, and the… |
flow_request_secret | Ask the flow's owner to enter a third-party credential (API key, auth token, webhook secret) into Final's encrypted vault. THIS TOOL TAKES NO VALUE and no tool ever returns one — the human types it into a masked input in the Miami builder, and it goes straight into the vault. Why: flow builds are… |
flow_search_blueprints | SEMANTIC search over the vetted blueprint catalog — matches are ranked by what you MEAN, not by shared words, so describe the capability in plain language ('rewards for repeat customers' finds the loyalty blueprint). RUN THIS FIRST — before creating custom tables or hand-rolling a capability… |
flow_start_preview | Boot the flow's server-side preview sandbox (Vite dev server) — or reconcile a running one to the flow's current files — and return its public HTTPS URL already pinned to this flow's mock dataset: the maker's pick, else its vertical's (sushi, not restaurant). Open the URL in a browser to see the… |
flow_stop_preview | Stop the flow's preview sandbox and free its resources. The next start_preview cold-boots in a couple of seconds. |
flow_sync_preview | Reconcile a (running or cold) preview sandbox to the flow's current files and run the green-build gate (tsc + vite build). Returns the gate result — the fastest way to know your code actually compiles. The engine forces parts of package.json on every sync: the dev/build/typecheck scripts, and the… |
flow_update_custom_table | Evolve an EXISTING custom data table's schema: add columns, change existing ones (rename/retype — destructive for stored rows, use sparingly), or drop columns. The table is identified by its kebab-case name from list_custom_tables. Tables are ORG-WIDE, so a schema change lands for every flow and… |
flow_validate_flow | Deterministic STATIC checks against the platform contract: (1) guardrails — fabricated renderClient methods, forbidden browser APIs/imports, engine-file writes; (2) a REAL TypeScript check of command-frame usage against the PINNED .d.ts the app installs (the version is stamped in the result) —… |
flow_write_flow_files | Create or overwrite files in a flow's tree (full contents, not diffs). Engine-owned paths are rejected — see get_scaffold. Every write lands as a restorable checkpoint and is narrated in the builder chat. If a live preview is running, follow up with start_preview to sync it. Validate with… |
get_connection | Who this connection acts as: organisation, user, the company Hub tools act on and the companies you may switch to, the allowed and listed packs, and how to reach tools that are not listed. |
hub_add_customer_note | Add a note to a customer — an allergy, a preference, what happened with an order. Existing notes are KEPT; this appends. Takes the customer ID from get_customers. Staff read these in the cabinet, so write what the merchant said, not your own summary. |
hub_add_modifier_choice | Add one choice to an existing modifier, leaving the rest alone. This is the safe way to extend a modifier — unlike update_modifier, it cannot drop anything. Appends to the end unless sortOrder says otherwise. price is the extra charge per unit as a human amount ("0.70"); omit it for a choice that… |
hub_add_product_images | Add photos to an existing product — from public URLs, or as base64 bytes when the merchant attached the file itself and there is no URL. URL images are downloaded and stored on the platform, so the product never depends on someone else's site staying up. Existing photos are KEPT — this adds to… |
hub_add_tax_rate_to_group | Add an EXISTING rate to a tax group, or change that rate’s compounding flag within the group. Both ids come from get_taxes. This shares the rate — it does not copy it. The group starts charging the rate’s existing per-outlet percentages, and a later edit to that rate changes this group too. Use… |
hub_adjust_stock | Change the count of ONE variant at ONE outlet — the cabinet's "Adjust Inventory" action. CONFIRM WITH THE MERCHANT FIRST, repeating the product, the outlet, the reason and the number: this writes immediately, is permanently recorded against the employee in the stock history, and there is no undo… |
hub_assign_role | Move a team member onto a different role — this is how someone gains or loses access. Answers 'give Maria access to the reports', 'make him a cashier again', 'take away her permissions'. PERMISSIONS ARE POWER. Confirm with the merchant first, naming the person and the role out loud ("give Maria… |
hub_cancel_booking | Release a booked window. The order stays as it is — cancelling a booking is not a refund, and money is never moved here; if the customer is owed money, do that on the order. Confirm with the merchant before cancelling a booking somebody already paid for. |
hub_cancel_purchase_order | Cancel an order the merchant no longer wants. CONFIRM FIRST, naming the supplier and the PO number — there is no undo, and the order disappears from the list rather than showing as cancelled. REFUSED once any stock has been received against it: that stock is real and the record has to stay… |
hub_confirm_booking | Turn a hold into a real booking once the order behind it is paid, so it stops expiring. Needs the order the booking was sold on — confirming without one is refused, because a confirmed booking nobody can find on a receipt is worse than an expired hold. |
hub_create_booking_resource | Add one bookable thing to the company directory. Call get_booking_resources first — a resource is reused across every service, so a second "Marco" would split one barber into two calendars and let him be booked twice at once. The name is what staff will see in the calendar. |
hub_create_booking_rules | Create a booking policy. Call get_booking_rules FIRST and reuse a matching set instead — these are shared company-wide, not per product. `weeklyHours` are LOCAL wall-clock times at the outlet; if neither the outlet nor the company has a timezone the engine refuses availability with a 400, so fix… |
hub_create_category | Create a product category. Call get_categories FIRST — a second "Drinks" is easy to make and there is no merge. Pass parentId to make it a subcategory; leave it out for a top-level one. The cabinet's own form asks for a description, so ask the merchant for one rather than inventing it. This does… |
hub_create_customer | Create a customer. Call get_customers with the email or name FIRST — a duplicate splits one person’s order history in two and there is no merge from here. Email is required, exactly as in the cabinet's own customer form. Ask the merchant for anything you do not know instead of inventing it — an… |
hub_create_modifier | Create a new question the till can ask, with its choices. THIS ALONE DOES NOTHING AT THE TILL — follow it with link_modifier_to_category, or the modifier sits unused. Choose selectionType carefully, because it CANNOT be changed afterwards: "single" = pick exactly one (milk, cooking temperature)… |
hub_create_outlet | Open a new point of sale — the cabinet’s Add Outlet form. Name and the full street address (address, city, state, postCode) are all REQUIRED, exactly as on that form. Do NOT try to set a country: every outlet inherits the company’s country, and it can never be changed per outlet. Ask the merchant… |
hub_create_product | Create a product in the merchant's catalogue. Call get_products first to make sure it does not already exist. Prices are HUMAN strings like "19.99" — this tool converts them into the company's currency itself, so never send cents. Tax: the company's standard tax table is applied by default; pass… |
hub_create_product_option | Create a new variation axis with its possible values. Use it only when get_product_options shows nothing suitable. The axis is shared across the whole catalogue, not one product — so confirm the name and values with the merchant first and reuse an existing axis when one fits. |
