Pith speaks MCP, the standard AI assistants use to reach real apps. Connect it once and your morning turns into a sentence: what's waiting for approval? Most of what you do in the Inbox, you can do in a chat instead.
It's included on every plan, Free included, and it doesn't change your monthly limits.
What owners use it for
The short version: Claude reads your files and knows what day it is. Pith gives it hands on your Instagram. These are the moments it earns its place.
- 7:05, hands in the dough. "What's waiting? Approve it." Today's story goes to your Instagram. You never opened an app.
- A photo you took a minute ago. Give it to your assistant: "Post this to my feed: pistachio babka, out of the oven." It publishes now. On Free it counts toward your monthly stories like any other post; on Pro it doesn't count. Free allows two of these a day and adds a short "Posted with pith.day" line to feed captions; Pro allows ten and adds nothing.
- Your menu is a PDF. "Here's my menu. Add every item as a product, with prices." Claude reads the file, Pith gets twenty products, one message.
- A new item this week. "Add the pistachio babka at 32 shekels." It joins the products your daily posts rotate through.
- It sounds too formal. "Make Pith warmer. No exclamation marks." Your voice profile changes and tomorrow's draft is written from it.
- Sunday night, planning. "Fill next week with posts." A post lands on every empty day, around your usual posting time. Asking for it is your go-ahead: each one goes out on its day unless you change or remove it first, and each one counts toward your monthly stories. If your monthly stories run out, a post past the limit doesn't go out on its day, and Pith won't post it on a later day by itself either: it waits for you to post it or give it a new date.
- A holiday is coming. "Change today's story to say we're closed Thursday and Friday, back Sunday."
- Your grid changed. "Pull my new photos and drop the ones with the old logo."
- Did it work? "Did yesterday's story go out? Why not?" It reads the log and answers in plain words.
- How much is left. "How many stories do I have left this month?"
- You'd rather not think about it at all. "Every morning, read my Pith drafts. Approve one that names a product and publish it. Tell me what went out." Save that as a scheduled task in Claude. Your rules, your agent, your Instagram. Pith never posts a draft nobody approved; your assistant does what you told it, and every publish is one it made under your grant.
Connect it
You'll need the server address:
https://pith.day/api/mcp
In Claude: Customize → Connectors → + → Add custom connector, paste the address, and approve the connection when Claude sends you to Pith.
In Claude Code: run claude mcp add --transport http pith https://pith.day/api/mcp, then /mcp to sign in.
Anywhere else — Cursor, ChatGPT, an agent you built yourself: paste the address wherever the app asks for a remote MCP server. If it asks which transport, it's streamable HTTP. If it asks for an API key, it doesn't need one — you sign in with the same email or Google account you already use for Pith.
Before anything connects, you'll see an approval screen listing exactly what the assistant is asking for. Nothing happens until you approve it.
Your morning, by chat
The loop is the same one the Inbox runs:
- "What's waiting for approval this morning?" — your assistant lists today's pending drafts.
- "Show me the second one." — it reads the caption and can render the story image. A cold render calls the image model, so give it up to 90 seconds.
- "Approve it and post it." — approved and on your Instagram. Or approve it and post from the app later, or approve it with a time and it goes out then. Your call.
- "Make it warmer and drop the emoji." — your assistant rewrites the words on the story. An edit you asked for counts as approving it, the same as editing in the Inbox, so check the new version before you say post.
Other things worth asking for:
- "Fill next week with posts."
- "Add a Friday specials beat to my brand voice."
- "How many stories do I have left this month?"
- "My Instagram grid changed — pull the new photos."
- "Did yesterday's story actually go out?"
What it can and can't do
Your assistant can read and edit drafts, manage your schedule, photos and products, tune your brand voice, switch your daily flow, publish approved posts, and check your plan usage. The full list is on the AI assistants page.
It cannot:
- Post one of your daily drafts before it's approved. Approving is a separate step it takes when you tell it to — the same rule the app follows
- Switch on a standing auto-post. A post goes out on its own only when you gave that post a date or a time; nothing posts AI drafts nobody looked at
- Read your Instagram DMs, your comments, or your followers' details
- Charge you. It can hand you a checkout link to open yourself; paying still happens on the checkout page, in your browser
Permissions
There are four permissions: view, edit, publish, and checkout. An assistant that doesn't say what it needs gets the first three. Many, Claude included, ask for all four. The approval screen lists exactly what this one is asking for before you connect.
Disconnecting
Settings → Connected apps lists every assistant you've connected, what it may do, and when it last did anything. Hit Disconnect and its access stops immediately — no waiting period, and no need to change your password.
If something isn't working
The assistant says it can't find your account. Ask it to run whoami first — that's how it discovers which business it's working on. If that comes back empty, either the connection was made with a different email than your Pith account, or no Instagram account is connected yet. For the second, ask it to connect your Instagram: it gives you a one-time link to approve on Instagram.
A request times out. Generating a day of drafts or drawing a story image takes 60–90 seconds, and some assistants stop waiting after about a minute. Nothing is lost: drafts are saved as each one finishes, so ask again, or ask what's waiting, and it picks up the finished result. If what timed out was a post, ask whether it went out before asking again.
A story image download used up a slot. On every plan, asking for a story image to post yourself spends one of your monthly stories the first time you ask for that draft — exactly as it does in the app. Fetching the same draft's image again is free.
Publishing failed. That's not an assistant problem — see Pith isn't publishing to Instagram.
