Endpoint Security57
Transport & Reachability100
Schema Quality & AI Usability78
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 719 tokens (~143/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the io.github.printmoneylab/x402watch MCP server?

io.github.printmoneylab/x402watch is a hosted endpoint at https://api.x402.printmoneylab.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 5 exposed · ~719 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
x402_check_wash ~173

Get the aggregate wash-report dataset: 30-day total active buyers, real-volume %, suspected_wash and self_test counts, full 8-label distribution, 14-day wash percentage time series, and five anonymized case studies (Service A through E) with pattern signals. For per-address real-time wash analysis with full signal breakdown, use the paid POST /api/v1/wash/check HTTP endpoint ($0.05 USDC) — that endpoint speaks x402, agents pay and receive data in a single HTTP round-trip. Free tier. No payment required. Returns wash-filtered data using the same v2.0 algorithm as the paid endpoints.

NameTypeReqDescription
addressstringOptional wallet or seller address. When provided, the response includes a hint about the paid per-address endpoint.

Structured output declared, but exposes no named fields.

x402_get_categories ~88

List all 33 x402 service categories with aggregate stats: services count, 24h volume, transaction count, real-volume %, and label distribution. Use this to understand the shape of the x402 ecosystem before drilling into specific services or wallets. Free tier. No payment required. Returns wash-filtered data using the same v2.0 algorithm as the paid endpoints.

x402_get_service ~116

Get the full detail record for one x402 service: name, description, seller address, chain, price, 24h and total transaction stats, 30-day daily volume time series, buyer-label distribution, and top buyers. Use this to evaluate a single service's traffic composition. Free tier. No payment required. Returns wash-filtered data using the same v2.0 algorithm as the paid endpoints.

Refreshed every 5 min. Free tier. No payment required. Returns wash-filtered data using the same v2.0 algorithm as the paid endpoints.

Input schema present but exposes no named parameters.

Common questions

What is the io.github.printmoneylab/x402watch MCP server?

io.github.printmoneylab/x402watch is an MCP server listed in the public MCP registry as io.github.printmoneylab/x402watch. Wash-filtered intelligence for x402: categories, services, wash analysis, trends. This page covers its hosted endpoint (https://api.x402.printmoneylab.com/mcp).

Is the io.github.printmoneylab/x402watch MCP server safe to use?

io.github.printmoneylab/x402watch scores 79 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.printmoneylab/x402watch MCP server expose?

io.github.printmoneylab/x402watch exposes 5 tools: x402_get_categories, x402_get_service, x402_check_wash, x402_search_services, x402_get_trends. Their descriptions and schemas cost roughly 719 tokens of context every time the server is loaded.

Does the io.github.printmoneylab/x402watch MCP server require authentication?

No. We connected to io.github.printmoneylab/x402watch without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the io.github.printmoneylab/x402watch MCP server still maintained?

io.github.printmoneylab/x402watch is still listed as active in the MCP registry. We last reached this channel on 24 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
