Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account pith-day for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A hosted remote MCP server that lets an assistant publish photos, stories and carousels to an Instagram Business or Creator account and manage drafts, products,

What you can do: Check the connected account, profile and Instagram connection, and get a one-time link to connect Instagram for publishing.
When to use it: When you run an Instagram Business or Creator account and want to post photos, stories or carousels, approve AI-written drafts, or manage products, photos and the posting schedule from chat instead of the app.
Requirements: A remote streamable HTTP endpoint at pith.day with OAuth 2.1 sign-in through the browser; no local runtime, API key or Meta developer app. An Instagram Business or Creator account is required, and a pith.day account signed in with email or Google.

Before you install

The assistant can publish to Instagram, approve or reject drafts, edit the schedule, brand voice, products and photos, and delete uploaded photos. Free-plan feed captions get an attribution line appended, and downloading a generated story image spends one of the monthly story slots. Checkout links are handed over to open; nothing is charged by the assistant. Revoke access from the connected apps settings.

Installation

In SourceWeft

Open Pith — Instagram publishing in the dashboard and add it to a workspace.
Connect the required credentials. They are stored privately and never shown on public pages.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.pith-day%2Fpith-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Pith — the Instagram MCP server

Publish to Instagram from the chat you are already in.
A hosted remote MCP server for Instagram Business and Creator accounts. Your assistant posts your photo with your caption, on your say-so, through the official Instagram Graph API. Nothing to install, no API key to paste, no password to hand over.

[MCP] [auth] [Instagram] [hosted]

Connect Pith →

Add it

Your client will ask for a remote MCP server URL. This is it:

Streamable HTTP. Sign-in happens in your browser over OAuth 2.1 — the server issues the token, the client never sees a password of yours.

Claude (web, desktop, mobile)

Settings → Connectors → Add custom connector.
Paste the address above and connect.
Sign in with email or Google when Claude opens pith.day, and approve what it asks for.

Claude Code

Add it once, then /mcp to sign in.

Cursor, VS Code, and other config-file clients

Add the server to your MCP config:

json

{  "mcpServers": {    "pith": {      "type": "http",      "url": "https://pith.day/api/mcp"    }  }}

{  "mcpServers": {    "pith": {      "type": "http",      "url": "https://pith.day/api/mcp"    }  }}

Anything else

Wherever the app asks for a remote MCP server, paste the address.
Transport: streamable HTTP. Auth: OAuth — Dynamic Client Registration and Client ID Metadata Documents both work, so most clients need no manual setup at all.

First run

whoami — shows nothing is connected yet.
connect my instagram — the server hands back a single-use link into Instagram's official login. Approve there, and you land back on a done page.
whoami again — your account, with canPublish: true.
post this photo with this caption — it is live on Instagram. The reply tells you the exact caption that was posted and links the post.

An Instagram Business or Creator account is required — that is Meta's rule for API publishing, not ours. Switching a personal account over is free and takes a minute in the Instagram app.

What it does


Publishes your own content, free	Hand your assistant a photo and a caption and it goes up: a story, a feed post, or a 2–10 image carousel. One request, one post, immediately. Free accounts get 10 of these a day.
Runs the daily draft loop, when you want one	Pith can also write the posts: a few drafts a morning in your brand's voice, built from your own photos and products. Your assistant reads them out, you approve the good one, it goes up. Five a month on the free plan.
Keeps the boring account work in chat	Products and prices, the photo library, your brand voice, the week's plan, what is left this month. The same things the app does, without opening the app.

What you actually say

Real sentences, from the mornings this was built for.

When	What you type
A photo you took a minute ago	"Post this to my feed: fresh sourdough, 7am sharp."
Three shots from the shoot	"Make these a carousel with a short caption about the new collection."
7:05, hands full	"What's waiting for approval this morning? Approve it and post it."
Your menu is a PDF	"Here's my menu. Add every item as a product, with prices."
It sounds too formal	"Make that caption warmer and lose the emoji."
Sunday night, planning	"Fill next week with product posts."
Did it work?	"Did yesterday's story actually go out? Why not?"
How much is left	"How many stories do I have left this month?"

How this differs from the other Instagram MCP servers


It actually publishes	Through the official Instagram Graph API, with Meta's `instagram_business_content_publish` permission approved at standard access (2026-09-18). Not a scraper, not a private endpoint, not a browser it drives for you.
Nothing runs on your machine	It is a hosted remote server. No Python, no Node, no Docker, no cookie or session token to extract and keep fresh.
You never paste a credential	OAuth 2.1 with PKCE, DCR and CIMD. Instagram's own login screen grants access; Pith holds a scoped token, your client holds a revocable one, and neither ever sees your Instagram password.
Publishing is per-request, always	Every post is one explicit ask, or an approved draft you said yes to. There is no timer, no queue that fires on its own, and no way to ask it to post unattended.
It is a product, not a demo	A real SaaS with a free tier, a paid tier, a help centre and a human on [email protected]. Broken things get fixed.

`get_billing_status`	See your plan and subscription state	view
`get_checkout_url`	Get an upgrade link to open yourself. It never charges on its own	checkout

Settings

The switches you'd otherwise hunt for in the app.

View, edit and publish are granted by default; checkout only if a client asks for it. Every connection is listed in Settings → Connected apps on pith.day, and disconnecting cuts it off immediately.

Things worth knowing before you connect


Nothing is posted that you did not ask for	Either you asked for this post in this message, or you approved the draft it came from. The server has no path around that rule and no unattended mode.
Nothing goes out on a timer	Pith does not hold an approved post and release it later. If you want a post at 9:30, your own assistant's scheduled task can ask for it then — that is your action, under your grant, and you can stop it whenever you like.
Drawing a story takes a minute	When Pith makes the image rather than posting yours, an image model draws it. Sixty to ninety seconds is normal and your client will sit and wait.
Free-plan story images cost a slot	Asking to download a generated story image spends one of the five monthly stories the first time, exactly as it does in the app. Publishing your own photo never does.
Feed captions carry one attribution line on Free	Free-plan feed posts get a short `✨ pith.day/p/<handle>` line appended, and the response shows you the exact caption before you see it on Instagram. Paid plans post your caption untouched.

What it costs

The connector is included on every plan, free one included. There is no separate MCP fee and no card needed to start.

Plan	What you get
Free	10 publishes of your own content a day. 5 AI-made stories a rolling 30 days. One Instagram account.
Pro — $49/mo	Unlimited stories, unlimited publishes, reels, no attribution line.

Security and privacy

OAuth 2.1 authorization server run by pith.day: PKCE S256, Dynamic Client Registration, Client ID Metadata Documents, opaque tokens stored hashed.
Scopes are granular — view, edit, publish, checkout — and shown to you on the approval screen before anything connects.
Pith reads your Instagram profile and publishes what you ask it to publish. It does not read your DMs, your followers, or anyone else's account.
Checkout links are handed to you to open. Nothing is ever charged by an assistant.
Revoke any connection from Settings → Connected apps. It takes effect immediately.

FAQ

Is the server open source?

No — this repository is the documentation and the manifest for a hosted service. The server itself is the pith.day product. You connect to it; you do not run it.

Do I need an API key or a Meta developer app?

No. Pith's Meta app is approved at standard access, so any Instagram Business or Creator account can connect through the normal Instagram login.

Can it post to Facebook, TikTok, or LinkedIn?

Not today. Instagram stories, feed posts, carousels and reels are what it does.

Which clients work?

Anything that speaks remote MCP over streamable HTTP with OAuth: Claude and Claude Code, Cursor, VS Code, and a growing list of others.

What happens if a publish fails halfway?

The post is written down before it is sent, so a retry resumes the same post instead of creating a second one. Carousels in particular are not idempotent on Instagram's side, and this is handled.

Hebrew and RTL?

First-class. The product was built in Hebrew and English, and generated story text renders correctly in both.

Connect it

Two minutes, once. Publish your own content free, and see whether the drafts earn their place.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
