pegproof
Registry code: 5877fac176057746
pegproof states what the chain shows about stock tokens on Robinhood Chain: whether an address is a token in Robinhood's list, another issuer's listed token or a known look-alike (check_address, free), the addresses behind a ticker or company name (find_token, free), and supply, issuance, incident and past-state data paid per call with x402. It reports observations, not advice.

- Is pegproof live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is pegproof free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does pegproof have?
- 6 tools: find_token, incidents, check_address, token_events, token_summary, token_snapshot.
- Is pegproof safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 4 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
incidents 0.005 USDC paid 1h ago
Monitor all of Robinhood's stock tokens in one call: integrity incidents, newest first. An incident is a token whose supply or treasury balance diverged from its full mint/burn ledger, or a ledger rebaseline, with its type, status and block window. type=integrity (default), operational (collector errors) or all. On-chain observations and reconciliation findings, not financial advice. Costs $0.005 per call, paid with x402 (USDC on Base or Arbitrum One).

Not refused when outside: above 100 is cut to 100, below 1 becomes 1, as on the HTTP routes." } }, "additionalProperties": false }arguments 22 linescheck_address auth-required never probed
Check a contract address on Robinhood Chain before buying, holding or accepting it: a token in Robinhood's list, a known look-alike, or unknown. Free. A look-alike answer names the token it imitates; another issuer's listed token is unknown with issuer_list. Same answer as GET https://pegproof.com/v1/address/{address}.

Audit when a Robinhood stock token's supply was created or destroyed: every mint, burn, issue, redeem and transfer, newest first. Pass a ticker (NVDA) or a contract address on Robinhood Chain (4663); page through with the opaque cursor (keyset on block and log index). On-chain observations reconstructed from chain event logs, not financial advice. Costs $0.005 per call, paid with x402 (USDC on Base or Arbitrum One).

Check a Robinhood stock token before an agent buys, holds or accepts it: the contract Robinhood lists, or a known look-alike? Pass a ticker (NVDA) or a contract address on Robinhood Chain (4663). For a listed token: total supply, treasury balance, multiplier, ledger coverage, open integrity flags and the look-alikes pegproof knows of. For a look-alike address: which token it imitates. On-chain observations reconstructed from chain event logs, not financial advice. Costs $0.002 per call, paid with x402 (USDC on Base or Arbitrum One).

Verify a Robinhood stock token's state at a past block: total supply, treasury balance and multiplier from the newest confirmed snapshot at or before it. Use it to check a historical position, report or trade against what was on-chain then. Pass a ticker or contract address and block=<number>. On-chain observations reconstructed from chain event logs, not financial advice. Costs $0.01 per call, paid with x402 (USDC on Base or Arbitrum One).
{ "type": "object", "required": [ "token", "block" ], "properties": { "block": { "type": "integer", "minimum": 0, "description": "A Robinhood Chain block number; the newest snapshot at or before it is returned." }, "token": { "type": "string", "description": "A ticker (NVDA) or a contract address (0x followed by 40 hex digits)." } }, "additionalProperties": false }arguments 19 linesfind_token unknown 1h ago
Find the contract address of a stock token on Robinhood Chain by ticker or company name, before an agent buys it. Free. Returns Robinhood's tokens with the look-alikes pegproof knows of, then other issuers' listed tokens (pegproof does not check their supply). At most 10 matches: total counts them all and truncated says when the list was cut.
{ "type": "object", "required": [ "query" ], "properties": { "query": { "type": "string", "maxLength": 64, "minLength": 1, "description": "A ticker (NVDA) or a company name (Nvidia)." } }, "additionalProperties": false }arguments 15 lines
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id5877fac176057746.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/5877fac176057746/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
