Overview

AI-generated overview

A free personality-test server that lets an assistant administer a 62-statement Big Five/HEXACO test, score it into one of 64 types, and explain type profiles.

What you can do
  • Fetch the 62 public-domain IPIP statements and the 1-5 answer scale, then ask the user each one
  • Score the user's answers into a 64 Types code with trait percentiles, borderline letters, a summary and a shareable link
  • Look up research-backed profiles for a 4-letter base type, its variants, or a full 64 Types code
  • List the 16 base types and 4 variants with names, taglines and links
  • Show what is free versus optional paid reports, and get a checkout link for a paid product
When to use it
Useful when a user wants to take a personality test inside a chat, get their type scored, or read up on a specific type's traits, strengths, career and relationship notes. Also handy for comparing types or pointing someone to optional paid reports.
Requirements
Remote endpoint at 64types.app over streamable HTTP; no packages, environment variables, headers or authentication are declared. Only network access is needed.
Before you install
The assistant is expected to ask the user every statement rather than answering for them. Paid reports are optional and payment happens on Lemon Squeezy through a checkout link; the server itself does not take payment. Results are for self-understanding, not clinical diagnosis or hiring decisions.

Installation

In SourceWeft

  1. Open 64 Types: personality test 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.zachhhhh%2F64types/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

Add this to your client's mcpServers config.
