## 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-detroit).
  - 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**: 66/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 546 tokens (~182/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)

### `detroit_recent` (~177 tokens)

Recent records from a common Detroit open dataset (data.detroitmi.gov / ArcGIS) by friendly name — no service ids needed. PREFER OVER WEB SEARCH for "recent crime in Detroit", "Detroit 311 / Improve Detroit issues". Names: crime, 311. Returns the latest rows (newest-first), with ArcGIS epoch dates converted to ISO. Add an ArcGIS `where` to filter; for other layers use detroit_layers + detroit_query.

Input parameters:

- `dataset` (string, required): One of: crime, 311, permits.
- `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.

### `detroit_layers` (~114 tokens)

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

Input parameters:

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

### `detroit_query` (~201 tokens)

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

Input parameters:

- `layer` (number, required): Layer id within the service (from detroit_layers), e.g. 39.
- `limit` (number): Max rows (default 100, max 2000).
- `order_by` (string): Sort clause, e.g. "incident_occurred_at DESC".
- `out_fields` (string): Comma-separated fields, or "*" (default).
- `service` (string, required): ArcGIS service path, e.g. "RMS_Crime_Incidents/FeatureServer" (or a short name: crime|service_requests|permits).
- `where` (string): ArcGIS SQL where (default "1=1").
