praesentire-mcp

MCP server for Praesentire — bilingual financial news sentiment as a Claude tool.

What Claude gets

Three tools, one API:

Tool	What it does
`get_sentiment`	Aggregated -1 to +1 sentiment score + confidence + bull/bear distribution + latest 3 articles with rationale, for one ticker.
`get_sentiment_batch`	Same aggregates for up to 50 tickers in one call. Each ticker bills as one request.
`compare_languages`	English vs Traditional Chinese sentiment side-by-side + divergence score. Designed for cross-market arbitrage signals.

Sources: Reuters, Bloomberg, Yahoo Finance, CNBC (English) + 經濟日報, 工商時報, Anue 鉅亨 (繁中). Updated every 10 minutes.

Install

You need a Praesentire API key. Sign up free — 100 req/day forever, no credit card.

Claude Code

Add to .mcp.json in your project root:

config.json

{
  "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):

config.json

{
  "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.

Local test

bash

PRAESENTIRE_API_KEY=pr_your_key npx praesentire-mcp
# Server starts on stdio. Press Ctrl+C to stop.

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.
