AudioPen

The AudioPen MCP server

AudioPen runs a Model Context Protocol server. Point an MCP client at it and your assistant can search and read your voice notes while you work. Ask what you said about a project last week, turn a rambling note into an email, or pull up the transcript behind a note you cleaned up.

The connection is read-only. Your assistant can look things up. It can never change or delete a note. Using it is part of AudioPen Prime.

If you use ChatGPT or Claude, the setup guide walks you through those two step by step. This page describes the server itself, for every other client.

Add it to a client

Open the place your client adds a remote MCP server. Different apps call it connectors, apps, integrations, or tools.
Enter https://mcp.audiopen.ai/mcp and pick OAuth if the client asks how to authenticate.
Enter the email address on your AudioPen account, then the one-time code we email you.
Ask your assistant something about your notes.

The three tools

search_notes
Searches your notes by keyword. One search matches note text, titles, original voice transcripts, tag names, and folder names. Results come back newest first, up to 50 per page, each with its tags and folder.
library_overview
Lists every tag and folder in your library, with a total note count. This is what an assistant reaches for when a request is vague and it needs to see what you actually write about.
get_note
Returns one note in full, including the original voice transcript from before AudioPen rewrote it. Useful for comparing what you said with what you kept.

What it cannot do

Create, edit, delete, move, or tag a note. The server has no way to write to your library.
Reach any account other than the one you signed in with.
See your AudioPen login. Your client holds a token issued by this server and nothing else.

Signing in

Adding the server opens an AudioPen sign-in page. Enter the email address on your account, then the one-time code we email you. It is the same login you use in the AudioPen apps. There is no API key to copy and no password to paste, and your client never sees your AudioPen credentials.

An account without Prime can reach the sign-in page, but stops there with a note about upgrading. If a connection expires, remove AudioPen in your client’s settings and add it again.

For implementers

Dynamic client registration at /register, plus client ID metadata documents. There is nothing to request from us before you connect.
Grant types authorization_code and refresh_token. Code challenge method S256.
An unauthenticated call to /mcp returns a 401 with a WWW-Authenticate header pointing at the resource metadata.
