MCP Playground

Every tool this node serves, called live from your browser against this same site. All tools here only read. Nothing on this page signs, claims, pays, or changes anything.

Tools

The list comes from tools/list. Each form is built from that tool's input schema. Run sends one tools/call. The plain-English notes only restate what the reply says. The raw JSON is beside them.

Signed records

Load the signed hub records from hub_updates, pick one, and check its ed25519 signature in this browser. The page rebuilds the signed bytes, confirms they hash to the record's hash, and refuses small-order and non-canonical keys before it verifies. Turn on tamper to flip one byte and watch the check fail. This checks the author signature only, not the node's allowlist or approval count.

Treasury and Ecosystem Fund

Read live from treasury_balances and ecofund_limit on every load. If a read fails, a cached figure is standing in for the live read, or a figure is missing, the panel says Data unavailable and shows no number.

H2H card: /.well-known/h2h-card.json

This node only reads. An agent that also signs SAGE C4 transactions needs its own signer. One option is sa-forge-signer by ttdonovan (llms.txt): unofficial and self-hosted; review its security chapter before use.
