As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

histor_checkServer history (HISTOR)read-only
Look up an MCP server in HISTOR, a public append-only log of MCP tool sets: when its tool set was first pinned, how often it changed, and what the pattern scan found. HISTOR answers from its own observations and never contacts the server.
tool_list_costTool list token costread-only
How many tokens an MCP server's tool list adds to every model request, what that costs per 1,000 requests, the heaviest tools, and where it sits among 18,204 packages and 16,170 remote servers. Send a tools/list or name a server HISTOR observes.
warden_scanScan tool definitions (WARDEN)read-only
Scan an MCP server's tools/list with WARDEN, the open-source MCP firewall: static rules and a threat list over every name, description, schema and annotation. Returns allow or block and each finding with its rule and severity. Quoted fragments of the scanned text are left out of the answer.
x402_checkx402 payment checkread-only
Check a signed x402 USDC payment before submitting it: recovers the EIP-712 signer, runs USDC's own checks and the seller's terms, and when the signature fails names the domain it was really made for (e.g. Base Sepolia's 'USDC' used on Base, where USDC is 'USD Coin').
