## 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-tn-dmv).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 7 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 55/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 831 tokens (~415/item across 2 items; 2 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 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.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (2)

### `tn_dmv_driver_service_centers` (~376 tokens)

Find Tennessee driver service centers (Department of Safety and Homeland Security) with street address, county, hours, phone, coordinates, and exactly which services each of the 186 locations performs. Tennessee publishes a per-location capability matrix, so this answers questions a plain address list cannot: "which Tennessee driver service center issues a REAL ID", "where can I take the CDL skills test in Tennessee", "which Tennessee location does handgun permits", "where do I get a vision test near Knoxville", or "is there a driver services kiosk in Memphis". Locations split into full service centers, self-service kiosks, county clerk partners and express counters. Filter by city, county, ZIP, name or required service; call with no arguments for all 186.

Input parameters:

- `city` (string): City name, e.g. "Nashville", "Oak Ridge". Matched loosely, so spacing does not matter.
- `county` (string): Tennessee county name, matched as a substring, e.g. "Davidson", "Shelby".
- `limit` (number|string): Max locations to return (default 50, max 200).
- `name` (string): Location-name substring, e.g. "Oak Ridge", "Express".
- `service` (string): Require a service, matched as a substring. Published services: REAL ID, new application, photo ID, handgun permit, vision test, road or motorcycle test, knowledge test, CDL skills test, renewal, name…
- `zip` (string): Five-digit Tennessee ZIP code, or a prefix, e.g. "37830".

### `tn_dmv_impaired_driving_crashes` (~400 tokens)

Count Tennessee injury and fatal traffic crashes involving alcohol or drugs, from the Department of Safety and Homeland Security crash file for calendar year 2022. Each record is one person involved in an impaired-driving crash, carrying crash severity (fatal, suspected serious injury, suspected minor injury), the driver age group and gender, the investigating law-enforcement agency, date, time and coordinates. Answers "how many fatal DUI crashes in Tennessee", "which age group is involved in the most alcohol-related crashes in Tennessee", "drug-involved crashes by police agency", or "impaired driving crashes by month". Group results by age_group, gender, severity, agency, substance or month, and get a sample of the underlying records with latitude and longitude for mapping.

Input parameters:

- `age_group` (string): Age band substring as published, e.g. "21 to 24", "80 & Up", "16 to 17".
- `agency` (string): Investigating agency substring. State troopers are published as "THP District 3 - Nashville" and similar, so "THP" selects all of them; city forces read "METROPOLITAN NASHVILLE POLICE DEPT", "MEMPHIS…
- `gender` (string): Published as "M" or "F"; "male"/"female" are accepted.
- `group_by` (string): Breakdown dimension: age_group, gender, severity, agency, substance, month. Defaults to age_group.
- `limit` (number|string): Max sample records returned alongside the counts (default 10, max 200).
- `severity` (string): Crash severity substring: "fatal", "serious injury", "minor injury".
- `substance` (string): "alcohol", "drugs", "both" (alcohol and drugs together), or "either" (default — any impairment).

## Common questions

### What is the Tn Dmv MCP server?

Tn Dmv is an MCP server listed in the public MCP registry as io.github.pipeworx-io/tn-dmv. Tennessee DMV MCP, Department of Safety and Homeland Security: the 186 driver service centers… This page covers its npm package (@pipeworx/mcp-tn-dmv).

### Is the Tn Dmv MCP server safe to use?

Tn Dmv scores 77 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 Tn Dmv MCP server expose?

Tn Dmv exposes 2 tools: tn_dmv_driver_service_centers, tn_dmv_impaired_driving_crashes. Their descriptions and schemas cost roughly 776 tokens of context every time the server is loaded.

### Is the Tn Dmv MCP server still maintained?

Tn Dmv 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 Tn Dmv MCP server under?

Tn Dmv 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 Tn Dmv MCP server?

VerifyMCP ran 14 checks on Tn Dmv, covering Malware scan, Known CVEs, Install scripts, Dependency health and 10 more. 2 items could not be completed, a gap on our side rather than a finding about Tn Dmv: Security disclosure and Stability. One category scores 0 for that reason, because we only credit what we can confirm. 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.
