Claude Code

Add to .mcp.json in your project root:

{
  "mcpServers": {
    "praesentire": {
      "command": "npx",
      "args": ["-y", "praesentire-mcp"],
      "env": {
        "PRAESENTIRE_API_KEY": "pr_your_key_here"
      }

Then claude and ask: "What's the sentiment on NVDA?"

Claude Desktop / Cowork

Edit your Claude Desktop config (%APPDATA%\Claude\claude_desktop_config.json on Windows, ~/Library/Application Support/Claude/claude_desktop_config.json on Mac):

{
  "mcpServers": {
    "praesentire": {
      "command": "npx",
      "args": ["-y", "praesentire-mcp"],
      "env": {
        "PRAESENTIRE_API_KEY": "pr_your_key_here"
      }
    }
  }
}

Restart Claude Desktop. The three tools will appear in the connectors list.

Example prompts

Once installed, Claude can answer things like:

"What's the news sentiment on NVDA right now?" → Calls get_sentiment("NVDA"), returns aggregated score + the 3 articles driving it.

"Compare English vs Chinese sentiment on TSMC — is there divergence?" → Calls compare_languages("TSM"), returns side-by-side plus divergence score. If |divergence| > 0.3, that's a notable cross-market signal.

"Sentiment on my watchlist: NVDA, AMD, AVGO, TSM, ASML, INTC, MU." → Calls get_sentiment_batch(["NVDA","AMD",...]), returns all at once.

"Why is NVDA down today? Pull sentiment + latest articles." → Calls get_sentiment("NVDA") and Claude summarises the rationales.
