Persnally

An MCP server that learns from your conversations with Claude and sends you personalized digests.

Your AI already knows what you care about. Persnally gives it a way to remember.

How It Works

1. You install Persnally as an MCP server in Claude Desktop
2. As you chat, Claude calls persnally_track to note what you're interested in
3. Persnally builds a local interest graph (no raw messages stored)
4. Daily/weekly, it curates a personalized digest and emails it via Resend

Install

npm install -g persnally

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "persnally": {
      "command": "persnally",
      "args": []
    }
  }
}

Restart Claude Desktop, then tell Claude:

"Set my Persnally email to [email protected]"

That's it. Start chatting — Persnally learns automatically.

MCP Tools

| Tool | Description | |------|-------------| | persnally_track | Extracts topics, intent, and sentiment from conversations. Called automatically by Claude. | | persnally_interests | Shows your current interest profile grouped by category. | | persnally_digest | Generates and sends your personalized digest email. | | persnally_config | Set email, frequency (daily/weekly), API preferences. | | persnally_forget | Remove a topic or clear all data. Full privacy control. |

Interest Graph

Persnally doesn't just store a flat list of interests. It builds a weighted graph with:

• Exponential decay — 7-day half-life keeps the graph fresh
• Sentiment awareness — "I hate CSS" deprioritizes CSS content
• Depth scoring — A brief mention scores differently than a deep dive
• Intent tracking — Learning, building, researching, debugging shape content selection
• Topic normalization — "React.js", "React JS", "ReactJS" all merge to one node
• Balanced allocation — Digest covers multiple categories proportionally

Privacy

Only structured signals are stored:

+ Topic name (e.g., "Rust async programming")
+ Weight (0.1 to 1.0)
+ Category, intent, sentiment
+ Entity names (e.g., "tokio", "axum")

Never stored: your messages, Claude's responses, code snippets, personal information.

Your interest graph is a JSON file at ~/.persnally/interest-graph.json. Read it, edit it, or delete it anytime.
