# praesentire-mcp

MCP server for [Praesentire](https://praesentire.com) — **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](https://praesentire.com/signup) — 100 req/day forever, no credit card.

### Claude Code

Add to `.mcp.json` in your project root:

```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):

```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.
