rta — zero-knowledge proof of a threshold
Prove a hidden value reached a threshold without revealing the value.
What it does
rta — zero-knowledge proof of a threshold is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

list_predicates· List the thresholds ṚTA can prove: for each predicate, the name, the threshold value, the circuit size and a plain-language label. Use before generating a proof, so the agent knows which statement it can prove without revealing the underlyiverify_proof· Verify a Groth16 zero-knowledge proof that a hidden value reached a threshold — for example 'the account balance is at least 1000'. The verifier learns that the threshold is met and never learns the value: the public signals are empty by co
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
