What Can You Connect to Claude?
Claude's custom connectors let you plug in your own data sources. Here is what is worth connecting - and how each one changes what Claude can do for you.
How it works
Install the extension
Add Readdit Later to Chrome, Brave, Edge, or Arc from the Chrome Web Store. Takes under a minute.
Your saves sync automatically
Every post and comment you have saved on Reddit is imported and kept in sync - no manual work.
Organize, search, and export
Label, filter, search with AI, export to Notion, and let the agent surface what matters.
Claude supports MCP connectors in two forms: remote connectors you add in Claude Settings → Connectors (work on web, desktop, and mobile) and local MCP servers you run alongside Claude Desktop. Both use the Model Context Protocol to give Claude access to data and tools it cannot reach on its own. The question is not whether to connect something - it is which connections actually change your workflow.
A connector is worth the setup when it replaces a recurring copy-paste routine. If you regularly paste Reddit threads into Claude for analysis, a Reddit connector eliminates that step permanently. If you paste database query results, a database connector does the same. The best connectors turn Claude from a general assistant into a specialist that already knows your data.
What you get
Reddit saves (Readdit Later)
Add your personal Readdit Later connector in Claude Settings → Connectors. Claude searches your saved Reddit posts by meaning, shows your notes, finds unread saves, and surfaces patterns across your library - on web, desktop, and mobile.
Files and code (filesystem)
A local filesystem MCP server lets Claude read and write project files. Useful for code review, documentation, and file-based workflows in Claude Desktop.
Databases (Postgres, SQLite)
Database connectors let Claude query your data directly. Ask questions about your data in English instead of writing SQL.
Notes and knowledge (Notion, Obsidian)
Connect your knowledge base so Claude can reference your notes, research, and documentation while working on tasks.
The problem. The fix.
You paste the same Reddit threads into Claude every time you need analysis - the copy-paste loop never ends.
A Reddit connector gives Claude permanent access to your saved research - no more pasting threads.
Claude gives generic advice because it cannot see the real research you have already collected.
Claude answers from your curated library instead of the open internet. Answers are grounded in sources you already vetted.
You pay for Claude Pro but only use it as a chat window - not as a tool connected to your actual data.
One connector setup turns Claude from a generic chatbot into a personalized research assistant.
Setting up connectors feels confusing - you do not know which ones are worth the effort.
The remote connector setup takes under 2 minutes - add a URL in Claude Settings and your saves are available immediately.
