README

Hunch MCP

Hunch gives your AI assistant calibrated judgments about text. For each text you send, it returns the probability that the answer to a yes/no question is yes, one option from your own list, a score on your own scale, or several yes/no answers at once. The answers come from Jev, TypeSafe's System One model, which returns numbers instead of generated text, so your assistant can sort, filter and count them.

The server is hosted at https://hunchsheet.app/mcp (Streamable HTTP). This repo holds the install files for Claude Code and Gemini CLI. Setup for Claude, ChatGPT, Cursor and VS Code is at hunchsheet.app/connectors.

Tools

ToolReturns
hunch_askThe probability of yes, 0 to 1, for each text
hunch_pickOne option from your list for each text, with its confidence
hunch_scoreA position on your levels (0 to n-1), the most likely level, and its confidence
hunch_multiOne probability per question for each text, up to 10 questions
hunch_balanceCredits left on your key

Good for leads, support tickets, reviews, survey answers, emails and any list of short texts you want judged the same way. It judges text only: no arithmetic, counting or dates. English works best. Put the definition inside the question, for example "Can this person approve a software purchase without asking someone else?" instead of "Is this a decision maker?".

Get a key

The form at hunchsheet.app emails a key with 100 free rows. After that, 5,000 rows cost $29 and credits never expire. One credit per answered text per question. Blank texts and repeats in the same call are free.

Claude Code

/plugin marketplace add Eddy1919/hunch-mcp/plugin install hunch@hunch-mcp

Set your key before starting Claude Code:

bash
export HUNCH_API_KEY=hunch_your_key_here

The plugin adds the server and a skill that tells Claude when to use each tool. Without the plugin:

bash
claude mcp add --transport http hunch https://hunchsheet.app/mcp --header "Authorization: Bearer hunch_your_key_here"

Gemini CLI

bash
gemini extensions install https://github.com/Eddy1919/hunch-mcp

Gemini CLI asks for your key during install and stores it as a sensitive setting.

Claude, ChatGPT, Cursor and VS Code

  • Claude (claude.ai and Claude Desktop): add a custom connector with the URL https://hunchsheet.app/mcp, then sign in with your key when Claude opens Hunch's page.
  • ChatGPT: in developer mode, create a connector with the same URL and sign in the same way.
  • Cursor and VS Code: one-click install buttons on hunchsheet.app/connectors.

Data

The texts and question in a tool call go to the Hunch server and to TypeSafe to compute the answer, and are not stored. Details at hunchsheet.app/privacy.
