## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-fcc).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 3 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 75/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 455 tokens (~151/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 84, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (3)

### `census_block` (~157 tokens)

Resolve a US latitude/longitude (decimal degrees) to its Census block, county, and state FIPS codes and names. Returns the 15-digit block FIPS, 5-digit county FIPS, 2-digit state FIPS, state code/name, and a bounding box. Pairs with the US Census API (FIPS codes are its join keys). Coordinates outside the US yield null FIPS values.

Input parameters:

- `censusYear` (string): Census vintage for the block geography: "2020" (default) or "2010".
- `lat` (number, required): Latitude in decimal degrees (e.g. 38.8976).
- `lon` (number, required): Longitude in decimal degrees (e.g. -77.0365).

### `census_area` (~155 tokens)

Resolve a US latitude/longitude (decimal degrees) to its full Census area record: block/county/state FIPS + names plus 2020 block population and FCC market-area codes (BEA, BTA, CMA, EAG, MEA, MTA, PEA, REA, RPC, VPC). Richer than census_block; use when you need population or FCC licensing market codes for a point.

Input parameters:

- `censusYear` (string): Census vintage: "2020" (default) or "2010".
- `lat` (number, required): Latitude in decimal degrees (e.g. 38.8976).
- `lon` (number, required): Longitude in decimal degrees (e.g. -77.0365).

### `county_for_point` (~91 tokens)

Lightweight reverse geocode: return just the county and state for a US latitude/longitude (decimal degrees) — county FIPS + name, state FIPS + code + name. Convenience wrapper over the FCC block-find service for when you only need the containing county/state, not the full block record.

Input parameters:

- `lat` (number, required): Latitude in decimal degrees.
- `lon` (number, required): Longitude in decimal degrees.

## Common questions

### What is the Fcc MCP server?

Fcc is an MCP server listed in the public MCP registry as io.github.pipeworx-io/fcc. FCC public geo/census APIs (geo.fcc.gov) MCP. This page covers its npm package (@pipeworx/mcp-fcc).

### Is the Fcc MCP server safe to use?

Fcc scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Fcc MCP server expose?

Fcc exposes 3 tools: census_block, census_area, county_for_point. Their descriptions and schemas cost roughly 403 tokens of context every time the server is loaded.

### Is the Fcc MCP server still maintained?

Fcc is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Fcc MCP server under?

Fcc declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Fcc MCP server?

VerifyMCP ran 16 checks on Fcc, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
