Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

cancellation
cancellation_penalty
Check US subscription cancellation terms without executing cancellation. Known vendors include review-only and retired scopes: their presence is not automation support. Adobe requires manual contract review. Typeform requires Basic, direct/self-serve platform scope and returns CANCEL_AT_PERIOD_END, not an immediate cancellation or refund. Missing scope, retired sources or unavailable current evidence return UNKNOWN.
refund
refund_eligibility
Evaluate a US consumer subscription refund against versioned source-backed rules. Returns UNKNOWN when required conditions are absent or the vendor requires approval or manual policy review.
return
return_eligibility
Evaluate whether a US consumer subscription purchase can be reversed under versioned source-backed rules. Returns UNKNOWN when required conditions are absent or manual review is required.
trial
trial_terms
Evaluate a live US consumer subscription trial offer. Supply observed availability, duration, card, and auto-conversion facts; the tool returns UNKNOWN instead of inferring current offers from static data.

Decide Policy Notaries — questions

Answers built from our own checks of this server.

What can Decide Policy Notaries do?
It exposes 4 tools, read directly from the server on our last check. Among them: cancellation_penalty, refund_eligibility, return_eligibility, trial_terms. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Decide Policy Notaries working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 693 ms. The bar chart above shows every period we have measured.
How do I connect Decide Policy Notaries?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Decide Policy Notaries need an API key?
No. Decide Policy Notaries completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Decide Policy Notaries?
It answers our handshake in 693 ms on average, which is faster than 14% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Decide Policy Notaries open source?
We cannot say either way: written in JavaScript, 1 stars on GitHub and 44 open issues, but we could not determine the licence, and without one the code is not open source by default.
