0 Trust /100

Dead

Every channel of this server has been unreachable for long enough to be marked dead. Its trust score is pinned to 0 and does not recover automatically: even once the server responds again it stays dead until it is manually reinstated.

Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability71
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 3762 tokens (~121/item across 31 items; 31 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 Management0
  • Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
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
Capabilities20
  • Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail

Unverified: 1 category

A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

Install

How do I install the MCPFax Public-Data Utility API MCP server?

MCPFax Public-Data Utility API is a hosted endpoint at https://mcpfax-utility.bowling-anthony.workers.dev/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.

Common questions

What is the MCPFax Public-Data Utility API MCP server?

MCPFax Public-Data Utility API is an MCP server listed in the public MCP registry as com.mcpscores/public-data-api. 31 tools: geocoding, weather, FX, SEC, DNS, more. Missing data named, unbilled. $0.001-$0.003/call. This page covers its hosted endpoint (https://mcpfax-utility.bowling-anthony.workers.dev/mcp).

Is the MCPFax Public-Data Utility API MCP server safe to use?

MCPFax Public-Data Utility API scores 0 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 MCPFax Public-Data Utility API MCP server expose?

MCPFax Public-Data Utility API exposes 31 tools: v1_geocode, v1_reverse_geocode, v1_timezone, v1_zip, v1_airports_nearest, and 26 more. Their descriptions and schemas cost roughly 3,717 tokens of context every time the server is loaded.

Does the MCPFax Public-Data Utility API MCP server require authentication?

No. We connected to MCPFax Public-Data Utility API without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the MCPFax Public-Data Utility API MCP server still maintained?

MCPFax Public-Data Utility API has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
