Trust breakdown (7 categories)

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. How we score → Why this is hard to score →

Endpoint Security69
Transport & Reachability100
Schema Quality & AI Usability80
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 635 tokens (~127/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management3
  • Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the DatoQA — Official Public Holidays MCP server?

DatoQA — Official Public Holidays is a hosted endpoint at https://datoqa.bhazarstudio.workers.dev/mcp/holidays, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
catalog ~79

Get the scope, allowed tool names, source IDs, endpoint and access policy for this thematic MCP. Call with no arguments when setting up this connection; skip it when the desired data tool and inputs are known. Use the listed domain directories only to resolve missing identifiers or coverage. This static catalog does not guarantee current availability; inspect the data response status and freshness.

Input schema present but exposes no named parameters.

get_public_holidays ~240

Get published public-holiday entries for one calendar and year or exact inclusive local date. Use a known region id directly (fr-metropole, gb-england-and-wales, hk-general, oh-de); consult list_holiday_regions only if scope is unknown. OpenHolidays entries retain multilingual names, subdivisions and half-day scope; set nationwide_only=true to exclude regional entries. Government feeds and third-party curated calendars are explicitly distinguished. Empty results do not establish working days; future dates can change, and aggregator dates are not individually government-confirmed.

NameTypeReqDescription
datestring–Exact local calendar date YYYY-MM-DD, for example 2026-12-28; cannot be combined with year.
