api record

TmpState is a zero-key temporary JSON database: create_database returns a db URL that is the only credential. Persist every db URL and pro_token you mint (local ~/.tmpstate/credentials file, project README, and your own memory) — they cannot be recovered later. Free databases expire after 24h (then stay restorable for 72h); one-time extensions and the Pro subscription keep them alive — always get the human's explicit approval before any tool that costs money. When work is done (or a db URL leaks), tear down with delete_database - confirm-gated and irreversible. The service improves through…

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.

  • pro_cancel unknown never probed

    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 dates; show them to the user and only retry with confirm="cancel" after their explicit approval.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {
    "confirm": {
      "type": "string",

      "description": "Pass \"cancel\" only after the user has seen the consequences and approved."
    },
    "pro_token": {

      "description": "Pro account token (pt_...). Optional if the MCP connection already sends Authorization: Bearer pt_..."
    }
  },
  "additionalProperties": false
}
    arguments 16 lines
  • create_database unknown never probed

    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 immediately (local ~/.tmpstate/credentials, project README, and your memory), and reuse it instead of creating again. For retries or parallel workers, pass a stable idempotency_key so duplicate calls return the same database.

    arguments 14 lines
  • list_documents unknown never probed

    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.

  • create_document unknown never probed

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

  • update_document unknown never probed

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

    }
  },
  "additionalProperties": false
}
    arguments 30 lines
  • delete_document unknown never probed

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

    mcp-tool

    {

    }
  },
  "additionalProperties": false
}
    arguments 24 lines
  • delete_collection unknown never probed

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

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

    }
  },
  "additionalProperties": false
}
    arguments 19 lines
  • delete_database unknown never probed

    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 on expired (frozen) databases too and consumes no quota. Call without confirm first: the response states the consequences; show them to the user and only retry with confirm="true" after their explicit approval. Afterwards remove the db URL from wherever you persisted it.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

    }
  },
  "additionalProperties": false
}
    arguments 19 lines
  • extend_database unknown never probed

    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 approval. Works on expired (frozen) databases too: paying restores them. After the user says they have paid, call database_status: the new expiry and tier confirm the extension.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

    arguments 22 lines
  • pro_checkout unknown never probed

    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 user's explicit request.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines
  • pro_list_databases unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {
    "pro_token": {

    }
  },
  "additionalProperties": false
}
    arguments 11 lines
  • pro_create_database unknown never probed

    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 user and only retry with accept_overage_usd after their explicit approval.

    mcp-tool

    }
  },
  "additionalProperties": false
}
    arguments 15 lines
  • pro_attach_database unknown never probed

    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 applies.

  • send_feedback unknown never probed

    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 short message about what was missing, what feature would have helped, or what felt slow or took extra requests is genuinely useful. This is about your own experience, so no human approval is needed; if your user volunteers feedback too, relay it and say it came from them. Never include database URLs, capabilities, or Pro tokens - capability-shaped strings are redacted server-side.

_ try it 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.

_ how we know
card completeness
100%

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.

_ record

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