Parsly’s Chrome extension collects what you can see on a page: a creator’s posts with their numbers, or a brand’s ads. Parsly in Claude does the same research by asking. You name an account and a question in your own words, Parsly fetches the posts, transcripts and comments, and Claude reads them and answers. It’s for anyone who’d rather ask “why did her last ten videos take off?” than sort a spreadsheet.
What does connecting Parsly to Claude do?
It gives Claude tools to fetch public data about any account, so it can answer questions it otherwise couldn’t. Claude on its own can’t see a creator’s latest posts or their numbers; with Parsly connected it can.
What Parsly fetches for Claude:
- A creator’s posts on LinkedIn, Instagram, X and Facebook through data providers, and a YouTube channel’s videos through Parsly in your own Chrome, with their views, likes, comments and dates, and how far each beat that creator’s usual numbers.
- Transcripts of videos, to see how the best ones open and are built.
- Comments, to see what people reacted to and asked.
- A brand’s ads from the Meta Ad Library, with how long each has run.
Parsly does the fetching and the sums (which posts are breakouts, how much each beat the usual). Claude does the reading: what the breakouts share, why they worked, and what you could post next in your own style.
How do I connect Parsly to Claude?
Add Parsly as a custom connector in Claude, then sign in to your Parsly account. It takes a couple of minutes.
- Copy Parsly’s connector address:
https://api.parsly.to/mcp - In Claude (claude.ai or the desktop app), open Customize, then Connectors.
- Click + Add, then Add custom connector. Name it Parsly, paste the address, and click Continue, then Add.
- Claude opens a page to sign in to Parsly. Sign in, or create your account, and click Allow.
- In a new chat, click + at the bottom left, open Connectors, and check Parsly is switched on.
Claude’s own help page: Getting started with custom connectors using remote MCP. Menu names checked October 2026; Claude changes them from time to time.
On a Team or Enterprise plan, an owner adds the connector once under Organization settings, then Connectors. Each person then finds it in Customize, then Connectors, and clicks Connect to sign in.
In Claude Code (the terminal, or the Code tab in the Claude app), paste this and Claude Code adds the connector and walks you through signing in:
Set up Parsly for me by following https://parsly.to/setup.mdOr add it yourself with claude mcp add --transport http --scope user parsly https://api.parsly.to/mcp, then type /mcp, choose parsly and sign in.
To disconnect, remove Parsly from Claude’s connectors. Connecting Parsly gives Claude Parsly’s tools only, never your other accounts.
What can I ask?
Ask the way you’d ask a colleague who’d done the research. Name the account by handle or link. Some to start with:
- “Why did @creator’s biggest posts this year break out? What do they have in common?”
- “Read the transcripts of this channel’s five best videos. How does each one open in the first ten seconds?”
- “What are people asking in the comments on her last ten posts?”
- “Compare these three LinkedIn creators. Which formats work best for each?”
- “Which of this brand’s Facebook ads have run longest, and what do they say?”
- “From what worked for these creators, plan my next four posts, in my own voice.”
Claude may ask Parsly for more as it goes, such as older posts or another platform. Each request shows in the chat, so you can see what was fetched.
What does it cost?
Parsly in Claude needs a paid Parsly plan, which comes with credits every month. Fetching from a data provider costs credits, a page of posts at a time; asking again for something Parsly fetched in the last day is free. Requests Parsly fetches in your own Chrome, such as a YouTube channel’s transcripts, cost no credits. Unused credits don’t roll over to the next month. Ask Claude “how many Parsly credits do I have?” at any time.
You also need Claude itself. The thinking happens on your own Claude plan; Parsly’s cost is fetching the data. The extension stays free.
How is it different from the Parsly extension?
| Parsly extension | Parsly in Claude | |
|---|---|---|
| Price | Free | Paid plan with monthly credits |
| How you use it | Open a page, click Collect | Ask in your own words |
| Where data comes from | The page you’re on, in your browser | Data providers, and your Chrome for some requests |
| What you get | A list with breakouts marked, CSV or text | Answers, comparisons and plans, written by Claude |
| Your own social accounts | Used, since it reads what you see | Not used for provider fetches |
Many people use both: the extension to look around for free, Claude for the questions that need many accounts or a plan.
What can’t it do?
- See anything private. Only public posts, comments and transcripts. No private accounts, no follower lists, and no impressions or reach for posts that aren’t yours.
- Show ad spend or targeting. The Meta Ad Library doesn’t publish them for most ads, so Parsly doesn’t have them.
- Fetch everything ever posted. Each request fetches a set number of pages; Claude asks for more when it needs them, and each page costs credits. Some platforms give only so much history.
- Guarantee Claude’s reading. The numbers are Parsly’s; the “why” is Claude’s judgement from them. Check the posts it points to before you copy an approach.
- Post for you. Parsly only reads. It never posts, likes or comments on anything.
Questions people ask
Is there a Claude Chrome extension?
Yes. Anthropic makes Claude in Chrome, an extension that lets Claude read, click and navigate websites with you, on Claude's paid plans. Parsly is a different thing: its own free Chrome extension for collecting posts and ads, plus a connector that works with Claude. You can use both.
What is a Claude MCP?
MCP, the Model Context Protocol, is the open standard Claude uses to connect to outside tools. Claude calls these custom connectors. Parsly is one: an MCP server Claude reaches over the internet, which gives it tools for fetching an account's posts, transcripts and comments.
Do I need the Parsly Chrome extension to use Parsly in Claude?
Not for posts and comments, which Parsly fetches through data providers. Some requests, such as a YouTube channel's transcripts, are fetched by Parsly in your own Chrome, so for those the extension needs to be installed and signed in.
Does it work on Claude's free plan?
Claude's free plan allows one custom connector, so it can be Parsly. Parsly's side needs a paid Parsly plan, since fetching data from providers costs money.
Does Parsly read my Claude chats?
No. Claude sends Parsly only the requests it makes to Parsly's tools, such as which account to fetch. Parsly answers with the data, and Claude does the reading and writing.
Can it see private accounts or ad spend?
No. Parsly fetches only what's public: posts and their numbers, transcripts and comments. It never has private accounts, other people's impressions, ad spend or targeting.
