Nothing serious here today

Today is the operative word: we check ChangePacket every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 3

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

buy

buy_changepacket_calls

Use only when free usage is exhausted or persistent production use is needed. Returns a Stripe checkout URL for 2,000 prepaid ChangePacket calls for $9; it does not itself charge or expose payment credentials.

mcp

check_mcp_surface_changes

Use when an agent depends on a remote public HTTPS MCP server and needs to know whether its tool catalog changed. First call stores the tools/list baseline; later calls return only added, removed, or modified tools plus compact risk hints. Avoid for private/authenticated MCP endpoints or as a substitute for a full security audit.

url

check_url_changes

Use for repeated research on one public webpage when the agent only needs what changed since its last call. First call stores a baseline; later calls return added/removed text lines. Avoid for authenticated/private pages, binary files, or one-time page reading.

ChangePacket — questions

Answers built from our own checks of this server.

What can ChangePacket do?

It exposes 3 tools, read directly from the server on our last check. Among them: buy_changepacket_calls, check_mcp_surface_changes, check_url_changes. 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 ChangePacket 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 201 ms. The bar chart above shows every period we have measured.

How do I connect ChangePacket?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does ChangePacket need an API key?

No. ChangePacket completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is ChangePacket?

It answers our handshake in 201 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
