Statory statistics inside Claude and ChatGPT

Statory runs an MCP server. Add it once as a custom connector in Claude or ChatGPT, and when you say "run a t-test on this table" the assistant executes Statory’s own statistics engines.

What it can do

  • Call the seven core analyses (frequency, descriptives, crosstab, t-test, ANOVA, correlation, regression) directly as tools
  • Pick and run any of the 102 analyses that are open to the connector
  • Get the same tables, the same APA sentence, and the same "how many cases" contract you see on the web
  • Optionally receive chart specifications (JSON)

What it does not do

  • AI interpretation — there is no such tool here. It produces numbers and tables only.
  • File upload or CSV parsing — that lives on the web app (/intake).
  • Anonymous use — the first connection asks you to approve with a Statory account.

How to connect

Server address

https://api.statory.org/mcp

The same address goes into both clients. It is read from the server itself.

Claude

  1. Open Settings → Connectors (or Integrations).
  2. Choose "Add custom connector".
  3. Paste Statory's MCP address.
  4. Press "Connect"; a browser window opens with the Statory sign-in page.
  5. After signing in you see the approval screen. Check the client name and the return address, then press "Approve". If the return address is one we have not seen before, the screen says so.
  6. You are returned to the client and the connection is done. Declining leaves nothing behind.

ChatGPT

  1. Turn on Settings → Security and login → Developer mode.
  2. Go to Plugins → Browse plugins.
  3. Press the + next to the search box.
  4. Fill in name, URL and OAuth, then press Create.
  5. Press Connect; the Statory sign-in and approval screens appear — the same ones Claude shows.
  6. In a conversation, reach it through + → More → Statory.

The 9 tools

All nine are read-only: nothing is deleted or modified, and nothing leaves Statory.

ToolTitleWhat it does
frequencyFrequencyDistribution of categorical variables
descriptiveDescriptiveMeans and standard deviations
crosstabCrosstabRelationship between two categorical variables
independent_ttestT-testCompare means between two groups
one_way_anovaOne-way ANOVACompare means across three or more groups
pearson_correlationCorrelationAssociation between continuous variables
multiple_regressionRegressionIdentify factors that influence an outcome
list_analysesList analysesLists the statistical analyses this server can run.
run_analysisRun analysisRuns one of the listed analyses on a table.

The options field of run_analysis

options is a free-form object: each engine accepts different keys. Its shape is the same as the options of the web request (/api/v2/analyze). The list of open analyses comes back from the list_analyses tool, and on the web each analysis shows the same keys in its engine-settings panel.

When it is absent the engine default applies; nothing is silently substituted.

Where the data goes

  • The table you send goes to the engine only; it is not stored after the calculation.
  • The response never carries the raw data back — only aggregated tables and the report sentence.
  • One line is written to your analysis history (which analysis, which variables, how many cases). The data itself is not in that line.
  • You can read that history at /history; deleting your account follows the account-deletion policy.
  • No credits are charged for MCP runs.

Limits

  • A table can hold up to 1,000,000 cells (rows × columns), with at most 1,000 columns.
  • Each request body is capped at 12MB.
  • Each account can run 60 analyses per hour.
  • An analysis that runs past 120 seconds stops and says so.

Frequently asked

These entries are kept in Korean, the same text the Korean guide shows.

ChatGPT에 「커스텀 커넥터」가 안 보인다
개발자 모드가 꺼져 있습니다. 설정 → Security and login → Developer mode 를 켜 주세요.
「등록 실패」로 연결이 끝난다
인가 서버 설정이 아직 켜지지 않은 것입니다. 운영자에게 알려 주세요.
「로그인이 필요합니다」가 계속 뜬다
커넥터를 지우고 다시 붙여 보세요. 허락이 만료됐을 수 있습니다.
「열려 있지 않습니다」라고 한다
그 분석은 MCP로 열지 않은 것입니다. 웹 화면에서는 쓰실 수 있습니다.
표가 너무 크다고 한다
한 번에 보낼 수 있는 크기가 있습니다. 행을 나누거나 분석에 쓸 열만 보내 주세요. 상한은 `/guide/mcp` 에 적혀 있습니다.
「한 시간에 …번까지」라고 한다
시간당 실행 수에 한도가 있습니다. 잠시 뒤 다시 하시면 됩니다.
파일을 올리고 싶다
지금은 표(값)만 받습니다. 파일은 웹 화면(`/intake`)에서 올려 주세요.
ChatGPT 앱 목록에서 안 보인다
아직 심사 중일 수 있습니다. 그동안에는 개발자 모드에서 커스텀 커넥터로 직접 붙이시면 같은 서버를 쓰실 수 있습니다.
