Measured tools (10)

• search_mcp_registry

  Search the continuously-maintained MCP server registry (deduped, quality-scored, refreshed every 30 min) by name/title/description. Free; returns up to 25 matching servers with score, status, remotes and packages. For the FULL corpus (~1500 servers) use get_mcp_registry_snapshot (paid, x402).

  Parameters:

  • limit — integer — max results 1-25 (default 10)
  • query — string — case-insensitive substring matched against server name/title/description; omit for the top servers by quality score

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_registry_highlights

  Top 10 MCP servers by quality score + trending (new arrivals / score risers) + snapshot freshness. Free.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• verify_mcp_server

  Free preview-grade trust report for one registry MCP server: a transparent 0-100 grade from cached signals (registry status, endpoint presence, freshness). The full report with a LIVE endpoint reachability probe + component breakdown is paid (verify_mcp_server_report, x402).

  Parameters:

  • server (required) — string — MCP registry server name (use search_mcp_registry to find one)

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_x402_services

  List the x402 services discovery catalog's active edge, liveness-probed: know a service is up and correctly demanding payment before you pay it. Free; up to 25. For the full liveness-probed feed use get_x402_services_snapshot (paid, x402).

  Parameters:

  • limit — integer — max results 1-25 (default 10)
  • payable_only — boolean — only services currently returning 402 (payable right now)

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• feeds_status

  Freshness/health of both feeds (snapshot ages, counts, available change-baseline dates). Free.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• assess_agent_risk

  Verify-before-you-pay: a read-only fraud/impersonation RISK assessment (0-100, higher = riskier) for an ERC-8004 agent on Base, cross-referencing its DECLARED identity (agent-card) against on-chain control (ownerOf). Flags owner-mismatch, registration-inconsistency, off-chain/unproven cards, dead endpoints, and orphaned identities. Free; from a maintained sample of the first agentIds. Look up by tokenId (agentId) OR by the counterparty wallet/payTo you're about to pay (address — 0x… or eip155:8453:0x…). Omit both to list the sample (riskiest first).

  Parameters:

  • address — string — the wallet/payTo you're about to transact with (0x… or CAIP-10 eip155:8453:0x…); resolves to the matching agent(s)' risk in the sample
  • agentId — integer — ERC-8004 Identity tokenId on Base; omit to list the maintained sample

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_mcp_registry_snapshot

  PAID (x402): returns x402 payment instructions for the FULL deduped, quality-scored MCP registry snapshot. Use search_mcp_registry (free) for targeted lookups.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_registry_changes

  PAID (x402): returns x402 payment instructions for the registry delta (added/removed/changed servers) since a daily baseline — the cheap habit endpoint for repeat callers.

  Parameters:

  • since — string — baseline date YYYY-MM-DD (see feeds_status for available dates)

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_x402_services_snapshot

  PAID (x402): returns x402 payment instructions for the FULL liveness-probed x402 services feed.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• verify_mcp_server_report

  PAID (x402): returns x402 payment instructions for the FULL verification report (LIVE endpoint probe + component breakdown) for one registry MCP server.

  Parameters:

  • server (required) — string — MCP registry server name

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
