XBRL Filing Check
What it does
Check a public XBRL or ESEF filing against the taxonomy and disclosure-system rules, with exact rule-code evidence
Validate one public iXBRL/XBRL financial filing against XBRL 2.1, Inline XBRL, Dimensions, calculation and dimensional consistency, and the SEC EFM, ESMA ESEF, or HMRC filing checks with exact rule-code evidence, or compare two filings period-over-period, with a clear automated-versus-human-review boundary.

XBRL Filing Check questions
Scope and boundaries for XBRL Filing Check.
01What does XBRL Filing Check actually check?
Validate one public iXBRL/XBRL financial filing against XBRL 2.1, Inline XBRL, Dimensions, calculation and dimensional consistency, and the SEC EFM, ESMA ESEF, or HMRC filing checks with exact rule-code evidence, or compare two filings period-over-period, with a clear automated-versus-human-review boundary.
02What does it never do?
It reports what its pinned engine measured and nothing more — it does not judge quality, correctness of your underlying business decisions, or anything outside its stated scope, and it never fabricates a result.
03What does it cost?
Nothing. Every published app is free to use with fair-use rate limits.
04Can my assistant connect directly?
Yes — any MCP-compatible assistant can connect straight to the canonical endpoint: https://powmcp.com/xbrl-filing-check/mcp. Marketplace listings are conveniences over the same live engine.
