MCP server

2026-08-17: Just released. Very 'beta version'. Use with caution. LLMs make things up, and I need to run through some training cycles with it.

The site has an MCP server. This allows you to connect your agent – Claude, Chatty-G, whatever – to it, and ask it questions.

To figure out how to do that, ask your LLM. The thing you need is the MCP server URL: https://johnnydecimal.com/mcp. You need an account to authenticate – get one free on the homepage.

What's on it

Free

  • The site documentation.
  • The Workbook: ask your agent to guide you through building a new system.
  • Course transcripts: ask a question about any of the courses, get a summary of what I said and a link to the episode.
  • Your Life Admin and Small Business systems (if you own them).
  • My views summarised from 5+ years of the blog and my own forum posts.

Coming soon

  • Johnny.Decimal User Guides: step-by-step guides using our 2 pre-built systems.
    • 'Help me plan my next holiday' will step you through it, with links to IDs, advice on organising your tasks, tips on accessing your data while you're away.
    • 'Help me organise a conference' if you're at work.
  • Knowledge of everything on YouTube: ask a question, get a link to a video.
  • If your agent supports it, read/write from your local JDex.
  • Explainer videos.

The MCP server works best if you also have the Johnny.Decimal skills installed. Configuring your systems will also help.

Privacy

When you connect to an MCP server – any MCP server – your agent necessarily has to send that server some of your data so that the server knows what to send back. And of course the server knows who you are, because you're authenticated to it.

I do not and will never log any of this data. It hits my server, a function responds, and nothing personal is ever saved, logged, or viewed by me. Not your user ID, name, email, IP address, or any of the text that your agent sent.

I log exactly two things: the name of the agent (e.g. claude-code/2.1.240) and the name of my tool that was called (e.g. list_documentation). This helps me troubleshoot connectivity issues.
