What is the P3x MCP server?

Most developer tooling work still happens through a UI a human drives. P3x MCP server moves it into the conversation instead. πŸ“š P3X OneNote MCP β€” Model Context Protocol server for Microsoft OneNote with read/write, table patching, strikethrough and cost calculation tools.

The short version

🌌 Bugs are evidentβ„’ - MATRIX️ 🚧 This project is under active development! πŸ“’ We welcome your feedback and contributions.

The tools it exposes

The server publishes 14 tools. What each one is for:

  • authenticate β€” Start device code flow
  • auth_status β€” Check whether tokens are cached
  • list_notebooks β€” Enumerate notebooks
  • list_sections β€” Enumerate sections in a notebook
  • list_pages β€” Enumerate pages in a section
  • get_page β€” Fetch page HTML (with data-ids for patching)
  • search_pages β€” Title substring search
  • create_page β€” Create a new page (raw HTML)
  • update_page β€” PATCH commands β€” replace/append/insert/prepend by data-id
  • delete_page β€” Delete page
  • read_table β€” Return page tables as structured JSON (rows β†’ cells with ids)
  • patch_cell β€” Replace a single table cell by cell data-id

Getting it running

Because this one is hosted, setup is mostly authentication β€” you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

What it needs from you

Configuration is passed through the environment: P3X_ONENOTE_CLIENT_ID. Treat anything key-shaped as a real credential β€” scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

How it compares

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. P3x's toolset β€” authenticate, auth_status, list_notebooks and 11 more β€” is a fair guide to whether it matches your workflow. It is maintained by patrikx3; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live β€” if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch P3x.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects P3x to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (authenticate, auth_status, list_notebooks, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with P3x directly.
