## 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 2026-11-06.

- **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-denue).

### `denue_search_nearby` (~119 tokens)

Find businesses near a coordinate. Returns establishments matching the keyword within the given radius (max 5000m).

- `lat` (number, required): Latitude (decimal degrees)
- `lng` (number, required): Longitude (decimal degrees)
- `radius_m` (number): Search radius in meters (1-5000, default 500)

### `denue_search_by_name` (~129 tokens)

### `denue_search_in_state` (~150 tokens)

Search businesses in a single Mexican state by keyword — matches against name, activity, or address. Use this for state-scoped queries that need more than just business name (e.g., "panaderia", "ferreteria"). Returns paginated results.

Input parameters:

- `page_start` (number): First record (1-based, default 1)

### `denue_establishment` (~52 tokens)

Get full details for a single establishment by DENUE ID (the "Id" field from search results).

Input parameters:

- `id` (string, required): Establishment Id (numeric string, e.g., "9988845")

### `denue_count` (~228 tokens)

Count establishments by economic activity + geography + size stratum. Returns totals — no detail records. Use for market-sizing questions like "how many pharmacies are in Jalisco".

Input parameters:

- `activity_code` (string, required): SCIAN economic activity code(s), comma-separated. 2-6 digits (sector → branch → class). Use "0" for any activity. Examples: "46" (retail), "722" (food services), "464111" (pharmacies).
- `area_code` (string, required): Geography code(s), comma-separated. "00" = all Mexico; 2 digits = state; 5 digits = municipality (state+mun). Examples: "09" (CDMX), "14039" (Guadalajara).
- `stratum` (string): Employee-size stratum: 0=any, 1=0-5, 2=6-10, 3=11-30, 4=31-50, 5=51-100, 6=101-250, 7=251+. Default "0".

## Common questions

### What is the Denue MCP server?

Denue is an MCP server listed in the public MCP registry as io.github.pipeworx-io/denue. INEGI DENUE MCP, Mexico's directory of economic units (~6M businesses). This page covers its npm package (@pipeworx/mcp-denue).

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

Denue scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 6 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 Denue MCP server expose?

Denue exposes 5 tools: denue_search_nearby, denue_search_by_name, denue_search_in_state, denue_establishment, denue_count. Their descriptions and schemas cost roughly 678 tokens of context every time the server is loaded.

### Is the Denue MCP server still maintained?

Denue is still listed as active in the MCP registry. We last reached this channel on 6 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 Denue MCP server under?

Denue 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 Denue MCP server?

VerifyMCP ran 16 checks on Denue, 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.
