api record

Pay-per-call MCP for EVM MEV history — sandwich detection + per-wallet exposure + per-pool density. Tools require x402 USDC payment on Base. tools/call returns a 402 envelope; settle X-PAYMENT and retry against the REST endpoint.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

3 never probed 0 of 3 classified

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.

  • mev_exposure unknown never probed

    Per-wallet MEV exposure score for an EVM address — samples recent blocks, identifies the wallet's swap-related tx via known DEX router targets, and applies a block-position sandwich heuristic to each. Returns 0–100 exposure score, sandwich count, swap count, and per-sandwich attacker/frontrun/backrun details. Multichain (ethereum/base/arbitrum/optimism/polygon). Costs $0.30 USDC on Base via x402.

  • sandwich_check unknown never probed

    Single-tx sandwich classifier. Takes a tx_hash + chain, fetches the tx + its block, applies the block-position heuristic against the immediately-preceding and immediately-following txs. Returns is_sandwiched + confidence (none/weak/medium/strong/confirmed) + attacker_addr + frontrun/backrun details. Costs $0.05 USDC on Base via x402.

  • recent_mev_density unknown never probed

    Pool-level recent MEV density. Takes a pool address + chain, fetches every log emitted by the pool in the lookback window, dedupes by tx_hash, then runs the sandwich heuristic per tx. Returns sandwich_density (0.0–1.0), density_band (none/low/medium/high), and up-to-5 sample sandwiches. Costs $0.10 USDC on Base via x402.

_ try it over mcp through the hub, ceiling 0

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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door
card completeness
70%

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.

spec deviations
0

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.
