Zero-key temporary JSON database for agents: one tool call, no signup, no OAuth, no API keys. Connect the official Tmpstate MCP server to Claude, ChatGPT, or Cursor through gate — one gateway URL, no config files, security-checked.
Free to start · No credit card · No hosting needed
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “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.”
“Use “database_status”: Usage, limits, tier and expiry for a database (GET $DB/__meta equivalent).”
“Use “list_documents”: List documents in a collection, oldest first. Response shape: {collection, items: [{id, data, created_at, updated_at}], next_cursor}. Docume.”
“Use “get_document”: Read one document by id. The stored fields are under .data.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Tmpstate holds up.
Operated by Tmpstate (tmpstate.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If Tmpstate adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose Tmpstate in the gate directory. No sign-in needed.
Tmpstate's tools are live in every AI client you've connected — with rules and logging built in.

Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
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
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}. Docume
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 t
delete_collection — Delete every document in a collection at once (useful to re-seed). Irreversible. To destroy the entire database, use delete_database instead

https://tmpstate.dev/mcpYes — Tmpstate operates its own remote MCP server at tmpstate.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
Add gate's gateway URL to your AI client once, then pick Tmpstate in the directory. No account or sign-in is needed. From then on, Tmpstate's tools are available in every client you've connected to gate.
No. Tmpstate runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Yes — you can get started with gate for free and connect Tmpstate in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
