Read a Substack Publication Through Your Muse

Through an AnythingMCP custom connector, your muse can read one Substack publication for you: list its latest posts, search its archive, open a post in full, read the top comments, and check its RSS feed.

What it does

Substack is a site where writers publish newsletters readers follow by email and on the web. The connector adds 7 read-only tools, with no API key and no Substack login. The muse can list recent posts newest first or by most liked, each marked as a newsletter, a podcast episode, or a thread, and as free or paid. It can search the archive for a topic, open one post by its link or number, read the top comments under a post, pull the RSS feed to see what is new, and turn a writer handle into the address of their publication. That is a calm way to catch up on a writer you follow, or find the one post you half remember, without scrolling through months of email.

How to use it

1. Start an AnythingMCP account and add the Substack connector.
2. Set the publication address the connector asks for. Use the home address only, with nothing after it.
3. In Muse, open Settings, then Connectors, and add a custom connector with the MCP server address AnythingMCP gives you. Sign in and approve.
4. Check the setup by asking for the ten latest posts, with the date and whether each one is free or paid, and compare with the publication page itself.
5. Ask in plain words, for example to find every post that talks about one topic, or to sum up the latest post in a few short points.

What you need

• A Muse account that can add custom connectors
• An AnythingMCP account with the Substack connector added
• The home address of the one publication you want to read

What to watch for

• One connector reads one publication. To read a different one, change the publication address in the connector.
• The connector does not log in, so it sees what a signed-out visitor sees. A paid post comes back as its free preview only, and paid content is not opened for you.
• It only reads. The muse cannot post, reply, or manage subscribers through it.
• Space out large archive sweeps. Heavy traffic in a short burst can be slowed down, at about one request a second.
• This is a custom connector, and Meta does not review custom connectors. You can disconnect it in Settings at any time. The muse prepares, you decide.
