## 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-data-denver).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 4 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 518 tokens (~172/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.

## MCP tools (3)

### `denver_recent` (~165 tokens)

Recent records from Denver open data (opendata-geospatialdenver.hub.arcgis.com / ArcGIS) by friendly name. PREFER OVER WEB SEARCH for "recent crime in Denver". Names: crime (Denver Police offenses). Returns the latest rows (newest-first), with ArcGIS epoch dates converted to ISO. Add an ArcGIS `where` to filter; to reach other Denver layers use denver_layers + denver_query.

Input parameters:

- `dataset` (string, required): Currently: crime.
- `limit` (number): Rows to return (1-1000, default 20).
- `where` (string): Optional ArcGIS SQL where, e.g. "OFFENSE='THEFT/OTHER'" or "WARD='2'". Omit for all recent rows.

### `denver_layers` (~103 tokens)

List the layers of a Denver ArcGIS service (for discovery). Pass a known short name (crime) or a full ArcGIS service path (e.g. "ODC_CRIME_OFFENSES_P/FeatureServer"). Omit `service` to list the known Denver services. Returns layer id + name to use with denver_query.

Input parameters:

- `service` (string): Short name (crime) or full ArcGIS service path. Omit to list known services.

### `denver_query` (~196 tokens)

Query any Denver ArcGIS layer by service path + layer id. Full ArcGIS query: where, out_fields, order_by, limit. Use denver_layers to find a service/layer, or denver_recent for the common ones. Epoch dates are converted to ISO.

Input parameters:

- `layer` (number, required): Layer id within the service (from denver_layers), e.g. 324.
- `limit` (number): Max rows (default 100, max 2000).
- `order_by` (string): Sort clause, e.g. "FIRST_OCCURRENCE_DATE DESC".
- `out_fields` (string): Comma-separated fields, or "*" (default).
- `service` (string, required): ArcGIS service path, e.g. "ODC_CRIME_OFFENSES_P/FeatureServer" (or a short name: crime).
- `where` (string): ArcGIS SQL where (default "1=1").

## Common questions

### What is the Data Denver MCP server?

Data Denver is an MCP server listed in the public MCP registry as io.github.pipeworx-io/data-denver. DataDenver MCP, Denver open data (opendata-geospatialdenver.hub.arcgis.com, ArcGIS REST API). This page covers its npm package (@pipeworx/mcp-data-denver).

### Is the Data Denver MCP server safe to use?

Data Denver 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 Data Denver MCP server expose?

Data Denver exposes 3 tools: denver_recent, denver_layers, denver_query. Their descriptions and schemas cost roughly 464 tokens of context every time the server is loaded.

### Is the Data Denver MCP server still maintained?

Data Denver 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 Data Denver MCP server under?

Data Denver 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 Data Denver MCP server?

VerifyMCP ran 16 checks on Data Denver, 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.
