    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 426 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 426 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.

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    43 of 44 parameters have a description (98%). The bar is 80%.

  • Pass
    Safety hints

    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass

Capabilities

Tools 8

admissions_game

Run the student's application past prefrosh.ai's simulated admissions committee for one college and round: five fictional readers (first, second, essay and faculty readers, and a dean who chairs) read it, argue, vote (accept / waitlist or defer / deny), and give the top 3 fixes. It is a simulation, not a prediction. Takes about a minute; the room plays out in the view. Pass the student's own application text exactly as they gave it (essays, activities, grades, scores) in "application"; never write, invent or improve content for them. If they have not shared their application, ask them to paste it first.

Discovered
compare

Compare 2 to 4 colleges side by side: admit rates by round, SAT/ACT ranges, testing policy, sticker cost, average net price, graduation rate, size and setting. If GPA or scores are given, adds the student's estimated odds (same model as prefrosh.ai/chance).

Discovered
game_debrief

App-only stage of admissions_game, called by the in-chat view after the vote. The committee chair writes the debrief: the three changes that would most help this application, each pointing to the student's own words. Simulation only; it never writes or rewrites essays.

Discovered
game_done

App-only. Called by the in-chat view when an admissions_game run ends, to record that it finished (school, AI token use and duration only; no application text). Returns nothing the user sees.

Discovered
game_read

App-only stage of admissions_game, called by the in-chat view, not by the model. One fictional admissions reader (the kind given) reads the student's application for this school and round and returns short notes: what works, what gave them pause, one fix, and the lines they marked. Simulation only; it never writes or rewrites essays.

Discovered
game_vote

App-only stage of admissions_game, called by the in-chat view after every reader has finished. The fictional committee discusses the readers' notes and votes Accept, Waitlist or Deny under the school's round, and returns the conversation and the vote. Simulation only.

Discovered
my_odds

Estimate a student's admission odds at one or more colleges, by round, with a likely range, from GPA and test scores (plus optional class rank, home state, legacy, first-generation, aid). Same model as prefrosh.ai/chance. Always tell the user this is an estimate from grades and scores only; essays, activities and recommendations can move it a lot. Needs at least a GPA or a test score; ask for them if missing rather than guessing.

Discovered
school_card

Show one college as a card: photo or campus map, overall admit rate and admit rate by round (Early Decision, Early Action, Regular Decision) with deadlines, SAT/ACT middle 50%, testing policy, sticker cost, average net price, graduation rate, biggest majors, and a link to its prefrosh.ai page. Use for "tell me about X", "how hard is it to get into X", "what are X's deadlines". Data is from the school's Common Data Set and federal data; cite the prefrosh.ai URL in the result.
