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.

roundwatch

roundwatch.get_watch

Read the durable state and any verified on-chain evidence for an existing RoundWatch watch ID. Read-only and free.

roundwatch.prepare_recovery

Validate and return the exact free HTTP request used to recover an existing watch after a paid create may have succeeded but the caller lost the returned watchId. Confirmed-settlement watches remain recoverable even after terminal expiry or post-activation indeterminate completion. This tool never signs, pays, or retries the paid create.

roundwatch.prepare_watch

Validate one expected future Algorand USDC payment and return the exact RoundWatch HTTP/x402 request to create a durable watch. This tool does not settle the x402 payment and does not create the watch by itself.

roundwatch.service_info

Return the live RoundWatch network, x402 service contract, USDC asset, price, limits, and documentation links. Read-only and free.

RoundWatch — questions

Answers built from our own checks of this server.

What can RoundWatch do?

It exposes 4 tools, read directly from the server on our last check. Among them: roundwatch.get_watch, roundwatch.prepare_recovery, roundwatch.prepare_watch, roundwatch.service_info. 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 RoundWatch 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 104 ms. The bar chart above shows every period we have measured.

How do I connect RoundWatch?

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 RoundWatch need an API key?

No. RoundWatch 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 RoundWatch?

It answers our handshake in 104 ms on average, which is faster than 93% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is RoundWatch open source?

The code is open source: it is published under the MIT licence, written in TypeScript and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at roundwatch-api.onrender.com, which runs on its operator's own terms.
