create_database

Create a temporary JSON database (24h TTL, no signup, no keys). Returns the db URL — the only credential — plus admin URL, limits and expiry. Create once per project/task, persist the db URL immediate…

database_status

Usage, limits, tier and expiry for a database (GET $DB/__meta equivalent).

list_documents

List documents in a collection, oldest first. Response shape: {collection, items: [{id, data, created_at, updated_at}], next_cursor}. Documents live under .data. Pass cursor to page.

get_document

Read one document by id. The stored fields are under .data.

create_document

Insert a JSON object into a collection (collections are created implicitly). Counts against the write and document quotas.

update_document

Shallow-merge a patch into a document (top-level keys overwrite; keys are never deleted). Counts against the write quota.

delete_document

Delete one document. Never blocked by quotas; frees a document slot. Emptying a whole collection? Use delete_collection instead of looping this.

delete_collection

Delete every document in a collection at once (useful to re-seed). Irreversible. To destroy the entire database, use delete_database instead.

delete_database

Destroy a database and all its documents immediately - the teardown for finished work and the revocation kill switch for a leaked db URL. Irreversible: unlike expiry there is no restore window. Works …

extend_database

Without a plan: returns the transparent pricing table for keeping this database alive longer. With a plan: returns a Stripe checkout URL for the human to pay — never buy without the user's explicit ap…

pro_checkout

Mint a Pro account token plus a Stripe subscription checkout URL ($8/mo, 3 always-on databases included). Persist pro_token immediately; the human pays in a browser. Never start checkout without the u…

pro_list_databases

List the Pro account's databases (ids, usage, limits, expiry) so a fresh session can reconcile against persisted db URLs. URLs are never stored server-side — match ids to the URLs you persisted.

pro_create_database

Create a new always-on database owned by the Pro account. Beyond the included allotment this costs extra per month — the tool then returns confirmation_required with the exact price; relay it to the u…

pro_attach_database

Attach an existing free/extended database to the Pro account: same URL, same data, TTL removed, quotas raised. Beyond the included allotment the same explicit overage consent as pro_create_database ap…

pro_cancel

Cancel at period end. This is not just a billing change — it schedules deletion of ALL databases on the account. Call without confirm first: the response spells out the consequences with concrete date…

send_feedback

Optional and free-form. TmpState is built for agents and the free tier stays free by getting better - and you, the agent, are the user whose experience matters here. After real use of a database, one …
