The quick answer
Open Claude → Settings → Connectors → Add custom connector, paste https://www.instaseer.com/mcp, and sign in to InstaSeer when the consent screen appears. That is the entire setup. In ChatGPT, enable Developer mode under Apps & Connectors and create a connector with the same URL and OAuth. From that moment your assistant can answer questions like "how many followers does @nike have?" or "analyze @glossier's last 100 posts" with live public data instead of guesses.
Everything the assistant fetches is the same source-backed public data the InstaSeer web app shows: visible posts, dates, captions, public engagement fields, and posting calendars. Nothing requires an Instagram login, and nothing touches private accounts.

CLI and editor clients authenticate with an API key instead. Create one on the MCP install page — it fills ready-to-paste config for each client, including a one-click Cursor install link.

instaseer_account_usagereports your plan and remaining credits, free, any time.
Prompts that work well
- "How many followers does @nike have on Instagram right now?"
- "Analyze @glossier's last 100 Instagram posts. What's their posting cadence, and which formats get the most engagement?"
- "Compare @fentybeauty, @glossier, and @rarebeauty over their recent posts and summarize what each does differently."
- "Before you run anything paid, check how many InstaSeer credits I have left."
How billing works
MCP usage draws from the same credit balance as the InstaSeer web app — one pool, whichever surface you use. A free account includes 50 credits a month, which covers one full 50-post analysis plus unlimited free lookups and previews. Paid plans add capacity: Creator (1,500 credits, $9/mo), Plus (5,000, $29/mo), and Pro (18,000, $99/mo), with one-time credit packs that never expire for overflow.
When your assistant runs out of credits mid-research it does not dead-end: the tool result explains what happened and includes a secure Stripe checkout link, so you can top up and continue in the same conversation.
What this deliberately does not do
Every tool reads what Instagram shows logged-out visitors, nothing more. Private accounts stay private. Instagram publishes no follower lists to logged-out visitors, so no InstaSeer tool can judge which followers are real, and the engagement rate comes back as a plain number rather than an audience-quality score — across brands with genuine audiences it legitimately ranges from under 0.02% to over 7%, so it only means something between close peers. If an AI answer claims otherwise, it did not get that from InstaSeer.
FAQ
Is this an official Instagram integration?
No. InstaSeer is independent software that reads public profile data — the same fields Instagram displays to any logged-out visitor. No Instagram login or API token is involved.
Which MCP transport does the server use?
Streamable HTTP in stateless mode at https://www.instaseer.com/mcp, with OAuth 2.1 or bearer API keys. There is no SSE stream and no session handshake, which keeps it compatible with current MCP client implementations.
Can my whole team use one connection?
Each person connects with their own InstaSeer account, so credits and rate limits stay per-account. CLI keys can be created and revoked individually on the install page.
