## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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 2026-10-23.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 76/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 570 tokens (~190/item across 3 items; 2 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **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 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.
  - Supports UI / widget rendering.

## MCP tools (2)

### `calculate_per_diem` (~193 tokens)

Calculate per diem

Use this when the user wants a per diem calculator, gsa per diem calculator, or travel per diem calculator with per diem meal deduction and a downloadable XLSX/CSV expense worksheet. Covers bundled GSA CONUS FY2026/FY2027 only; up to 10 trips, 10 contiguous stops per trip, 92 days between arrival and departure, and 400 day rows per call. Furnished government or registration meals reduce allowances; common-carrier meals and complimentary hotel breakfasts are not deductions. Same-day travel requires more than 12 hours; no times are taken. Do not use for OCONUS, lodging taxes, agency policies or FY2028.

Input parameters:

- `trips` (array, required): One to ten trips. Example: [{name:"DC",stops:[{location:"20001",arrive:"2026-10-27",depart:"2026-10-29"}]}].

Output parameters:

- `downloads` (object)
- `errors` (array)
- `fiscal_year` (number)
- `kind` (string)
- `note` (string)
- `preview_columns` (array)
- `preview_destinations` (array)
- `rates` (array)
- `source` (string)

Looks up 1 to 25 ZIP codes or City, ST locations in bundled GSA CONUS FY2026/FY2027 tables. The default fiscal year uses today in America/New_York. Ambiguous ZIPs return an item error; use calculate_per_diem with county to disambiguate. Do not use for OCONUS or FY2028.

Input parameters:

- `fiscal_year`: Federal fiscal year, defaulting to today in America/New_York. Example: 2027.
- `locations` (array, required): One to 25 locations. Example: ["10001","Austin, TX","Smalltown, KS"].
