## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-12.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

**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.

## 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.
