Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

check_answer Read-only

For a quiz question of a lesson: says whether the answer is right, which option is, and why. For an exercise: gives its hint and its reference answer to compare the learner’s attempt with (this server does not grade free text and never runs code); offer the hint first and the reference only after a try.

kindstring, required

A quiz question or an exercise

numberinteger, required

Its number in the lesson, from 1

patternstring, required

The pattern (its slug), as list_patterns gives it

langstring

The language of the answer: en (the default), pl; es, pt, fr and de for patterns and lessons (the course stays in English there)

answerstring

The learner’s answer: for the quiz the option’s text or its number (1 to 3); for an exercise optional

get_lesson
