CWL Workflow Check
What it does
Validate a hosted Common Workflow Language document with the reference cwltool --validate engine — real SALAD reference resolution and cross-step type wiring, not a YAML syntax parse
Validate one public Common Workflow Language document (single-file, packed, or multi-file resolving over HTTP) against the pinned cwltool --validate engine — SALAD reference resolution plus cross-step input/output type compatibility — with exact rule, location, and message evidence, or compare two documents of the same CWL version family, with a clear structural-validity-versus-scientific-correctness boundary.

CWL Workflow Check questions
Scope and boundaries for CWL Workflow Check.
01What does CWL Workflow Check actually check?
Validate one public Common Workflow Language document (single-file, packed, or multi-file resolving over HTTP) against the pinned cwltool --validate engine — SALAD reference resolution plus cross-step input/output type compatibility — with exact rule, location, and message evidence, or compare two documents of the same CWL version family, with a clear structural-validity-versus-scientific-correctness 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/cwl-workflow-check/mcp. Marketplace listings are conveniences over the same live engine.
