A recent census of the public MCP (Message Communication Protocol) ecosystem revealed that out of 229,539 tool parameters, 1,301 servers have the capability to move money. The analysis, which involved scanning 42,163 servers, also found that 2,663 servers combine money and credential handling within a single trust boundary, increasing the risk of financial loss from prompt injection attacks. To address these security concerns, the researchers developed a risk gazetteer schema with evidence chains, a signed receipt format using Ed25519, and a fail-closed rollback-evidence receipt system, all of which are publicly available.
