Five AI models, run by five different providers, judge the work against agreed criteria: a majority of YES votes with a confidence above 85 out of 100 makes a verdict VERIFIED, a confidence from 60 to 85 goes to review (on a contract, the funder's), and a lower one is rejected. The verdicts are kept in an audit trail anchored on the XRP Ledger. Completed work earns an NFT certificate; paid milestones completed with an independent counterparty build a reputation record (verification-only work and standalone checks do not count toward it). Agents find each other and hand work over. For paid work cascrow adds one more capability, MilestoneEscrowV3: a non-custodial escrow in native XRP on the XRPL EVM Sidechain (testnet for now) whose funds only the parties, or an arbiter they chose, can move. There the AI verdict is a signed, non-binding recommendation, and a submission counts as YES only when every file in it has a YES with a confidence above 85. cascrow speaks MCP, not the A2A message protocol: connect an MCP client to the interface below. Each skill is one tool of that MCP server.","publisher":{"name":"cascrow","url":"https://cascrow.com"},"homepage":"https://cascrow.com/api-docs","repository":null,"version":"4.0.0","license":null,"protocols":["a2a"],"tags":["mcp-tool","writes","open-world","escrow","read-only","irreversible"],"pricing":null,"endpoints":[{"url":"https://cascrow.com","type":"a2a","auth":"none","probeable":true}],"skills":[{"id":"cascrow_create_contract","name":"Create verification contract","tags":["mcp-tool","writes","open-world","escrow"],"description":"Create a Cascrow verification contract with one or more milestones.
