Pegproof MCP

An MCP server providing independent on-chain verification of Robinhood's 203 Stock Tokens on Robinhood Chain. It offers tools to check token addresses, retrieve supply and issuance data, monitor integrity incidents, and verify historical states, with free lookups and paid detailed queries via x402.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Checks and signals

Each line is separate evidence, not a trust score.

  • Passed Endpoint answered the live check ·
  • Passed Official MCP Registry namespace is tied to pegproof.com ·
  • Passed Endpoint is on the registry namespace domain ·
  • Availability 1 of 1 checks passed in 30 days

What you can do with it

  • Check if a token address is official or a look-alike
  • Audit mint, burn, and transfer events for stock tokens
  • Monitor integrity incidents across all stock tokens
  • Verify token state at a specific historical block

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

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.

Tools

check_address — Check a stock token address
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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}.

find_token — Find a stock token by ticker or name
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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.

token_summary — Token summary
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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).

token_events — Token issuance events
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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).

incidents — Integrity incidents
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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).

token_snapshot — Token state at a past block
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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).
