Performance

  • Not measured
    Fast (p50)

    Median latency 128 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 128 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured

Capabilities

Tools 3

calculate_class_grades

Use this when a teacher or tutor wants a weighted grade calculator for a whole class; list ID and info columns (student number, StudentID, email, SIS, section) in ignore_columns so they stay out of the grades. Examples: final grades from a gradebook, 'calculate my students' grades with Homework 20%, Quizzes 30%, Tests 50%', a gradebook template filled in, class average, or who is missing work. Takes a roster of scores (pasted table, list, or a Google Classroom / Canvas CSV or XLSX export as file) plus optional category weights, points possible, drop lowest per category, blank handling, extra credit and letter scale. Returns each student's final percent and letter (fraction math, rounded only for display), category scores, weights renormalized when a category has no graded work, class mean/median/distribution, missing-work list, and Excel + CSV downloads. Does not store data, connect to a school system, or make progress report PDFs (use generate_progress_reports).

Discovered
calculate_grade_needed

Use this when someone asks what they need on the final: 'what do I need on my final to get a B', final grade calculator, score needed on the final exam to pass, or a teacher asking what each student needs on the final for a C. Takes the current grade percent (or a list of students with current grades), how much the final is worth, and a target percent or letter (default all letters on the scale). Returns the score needed on the final for each target (and the points needed when final points are given), whether it is reachable, and what-if course grades. Assumes the final is a separate weight on top of the current grade; does not model a final inside a weighted category.

Discovered
generate_progress_reports

Use this when the user wants a progress report template filled in for students; list ID and info columns (student number, StudentID, email, SIS, section) in ignore_columns so they stay out of the grades. Examples: printable progress reports, grade reports for parents, 'make a progress report for each student'. Takes the same roster and grading settings as calculate_class_grades plus optional teacher comments per student, class name, teacher, term, report date and a subset of students. Returns one PDF with one page per student (current grade and letter, category scores, each assignment with excused/missing/dropped marks, missing work list, comment) and the Excel gradebook. Does not email or post reports, and does not store data.
