ProofPrice
com.proofprice/pricepaid in the official MCP registry.
Endpoint https://proofprice.com/api/mcp. Source: github.com/Screed369/proofprice-mcp.
The registry describes it as: Prices people actually paid, from official open data: homes, rents, fuel, energy, food, medicines.
On 2026-10-27 we read its 34 tools, but part of what it advertised was cut before our rules saw it: a description or schema past the size we read, more tools than we read, or a tool list split across pages. Nothing in the part we read matched, but the rest was not checked: this is not a clean result.

[](https://lazaretto.dev/mcp-registry/com-proofprice-pricepaid)How this was checked
Lazaretto connects to the endpoint the way any MCP client does, asks the server to introduce itself and list its tools, and reads every name, description, parameter schema and server instruction for tool poisoning: hidden directive blocks, orders to read local secrets, parameters built to carry secrets or the conversation out, orders that redirect another server's tools, and invisible characters. It never calls a tool. What we found across the registry.
