Installation

In SourceWeft

  1. Open SAT Score Percentiles MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.theluckystrike%2Fsat-score-percentiles-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

sat-score-percentiles-mcp

SAT score percentiles and class of 2026 SAT averages by state for AI assistants, from College Board's percentile tables and the 2026 SAT Suite Annual Report.

This is a Model Context Protocol (MCP) server. It answers from bundled College Board data, so it needs no API key and no network calls.

Tools

ToolWhat it returns
get_sat_percentileUser group and nationally representative percentiles for any SAT total (400-1600) or section score (200-800), with the class of 2026 national mean and score band.
get_score_for_sat_percentileThe lowest total or section score that reaches a target percentile, for example the 90th.
get_sat_scores_by_stateClass of 2026 SAT results for any state, DC, Puerto Rico or the US Virgin Islands: test takers, participation rate, mean total, Reading and Writing and Math, percent meeting benchmarks, 25th/50th/75th percentile scores and rank.
rank_states_by_satStates and DC ranked by mean score, participation rate, benchmark rate or test takers, with an optional minimum participation filter.

Every result has structured JSON, a one-paragraph summary, as_of, source (the College Board page or PDF) and more (a page on examscorecalc.com).

What it knows that your model does not

  • Class of 2026 SAT results, published by College Board in fall 2026: 1,954,833 test takers nationally with a mean total of 1045 (528 Reading and Writing, 517 Math), and the same figures for every state.
  • Each state's participation rate, which explains most of the gap between state averages. States that test every 11th grader have lower means than states where only college-bound students test.
  • The 25th, 50th and 75th percentile SAT scores for each state's class of 2026.
  • The exact College Board percentile for every 10-point score, in both reference groups, instead of a rounded guess.

Cursor

Add to ~/.cursor/mcp.json:

Node 20 or newer is needed for the local stdio version.

Example prompts

  • "What percentile is a 1350 on the SAT?"
  • "What SAT Math score do I need for the 90th percentile?"
  • "What was the average SAT score in Texas for the class of 2026, and how many students took it?"
  • "Which states had the highest SAT averages in 2026 among states where at least half of students took the test?"
  • "Is a 1200 a good SAT score in Ohio?"

Data sources

Full list with fetch dates and file hashes in DATA_SOURCES.md.

Limitations

  • The percentile page does not print a year. User group percentiles cover SAT takers from the past three graduating classes, as College Board states on that page.
  • State means depend on who tests. Compare states with similar participation rates, or use min_participation_pct.
  • Puerto Rico and the US Virgin Islands reports have no participation rate, so they are not ranked.
  • The Ohio supplement was not linked from the report index on 2026-11-03; it was fetched from the same College Board path pattern and parsed like the others.
  • Data are fixed at the 2026 reports. When College Board publishes the class of 2027 report, the data file is rebuilt with scripts/build_data.py.

get_sat_percentile

Get SAT percentile

Percentile rank of a digital SAT total score (400-1600) or section score (200-800, Reading and Writing or Math), from the College Board percentile tables: the user group percentile (actual SAT takers, past three graduating classes) and the nationally representative percentile (all US 11th and 12th graders). Also compares the score with the class of 2026 national mean (1,954,833 test takers) and score band.

Parametersscorerequiredsection

get_score_for_sat_percentile

Get SAT score for a percentile

The lowest SAT total or section score whose College Board percentile is at or above a target (for example the 75th or 90th percentile), for the user group (SAT takers) or the nationally representative group.

Parametersgroupsectionpercentilerequired

get_sat_scores_by_state

Get SAT scores by state

Class of 2026 SAT results for one state, DC, Puerto Rico or the US Virgin Islands from the College Board 2026 SAT Suite Annual Report state supplement: test takers, participation rate, mean total, Reading and Writing and Math scores, percent meeting college readiness benchmarks, 25th/50th/75th percentile scores, rank by mean, and the national comparison.

Parametersstaterequired

rank_states_by_sat

Rank states by SAT

Rank the 50 states and DC by class of 2026 SAT mean total, mean Math, mean Reading and Writing, participation rate, percent meeting both benchmarks, or number of test takers. Use min_participation_pct (for example 50) to compare only states where most students take the SAT, since low-participation states have higher means.
