---

Wind MCP bridges the Wind Financial Terminal (万得) with AI assistants via the [Model Context Protocol](https://modelcontextprotocol.io). It exposes **23 tools + 1 resource** covering market data, fundamentals, macro economics, screening, estimates, portfolio management, and date utilities — all accessible through natural language.

> **Platform:** Windows only (WindPy is a Windows COM-based library).

> Companion project to [Bloomberg-MCP](https://github.com/QmQsun/Bloomberg-MCP). Same architecture, same philosophy — but for Wind (万得).

## Key Features

- **Bloomberg → Wind Ticker Converter** — Accepts Bloomberg-style identifiers (`AAPL US Equity`, `700 HK Equity`, `601012 CH Equity`) and auto-converts to Wind codes (`AAPL.O`, `00700.HK`, `601012.SH`). Covers US, HK, JP, LN, CH equities, indices, commodities, and currencies.
- **Modular architecture** — server.py is a thin entry point. Handlers, models, formatters, parsers, and converters cleanly separated.
- **16 FieldSet shortcuts** — Pre-defined field collections (PRICE, VALUATION, PROFITABILITY, etc.) that expand to Wind field mnemonics.
- **Cache layer** — TTL-based in-memory cache with data-type-aware expiration (30s for realtime, 24h for static).
- **12 WindPy parsers** — Handle WSS, WSD, WSI, WST, WSQ, WSET, EDB, WSES, WSEE, TDAYS, TDAYSOFFSET, TDAYSCOUNT with NaN→None cleanup and column-to-row transposition.
- **Dynamic Screening** — Custom filtering with operators (gt, lt, between, in, eq) + ranking + slicing, without knowing Wind mnemonics.

## Dynamic Screening

Build custom screens with pre-validated field sets, filters, and ranking — no need to know Wind field mnemonics.

### Filter Operators

| Operator | Description | Example |
|----------|-------------|---------|
| `gt` / `gte` | Greater than (or equal) | `{"field": "roe_ttm", "op": "gt", "value": 20}` |
| `lt` / `lte` | Less than (or equal) | `{"field": "pe_ttm", "op": "lt", "value": 15}` |
| `eq` / `neq` | Equals / not equals | `{"field": "industry_sw", "op": "eq", "value": "电子"}` |
| `between` | Range (inclusive) | `{"field": "pe_ttm", "op": "between", "value": [10, 25]}` |
| `in` | Value in list | `{"field": "industry_sw", "op": "in", "value": ["电子", "计算机"]}` |

### Example: Find Undervalued High-ROE A-shares

```json
{
  "universe": "sector:全部A股",
  "fields": ["PRICE", "VALUATION", "PROFITABILITY"],
  "filters": [
    {"field": "pe_ttm", "op": "lt", "value": 15},
    {"field": "roe_ttm", "op": "gt", "value": 20}
  ],
  "rank_by": "roe_ttm",
  "rank_descending": true,
  "top_n": 20
}
```

## Cache Layer

Built-in cache reduces Wind API load with data-type-aware TTLs:

| Data Type | Default TTL | Rationale |
|-----------|-------------|-----------|
| Realtime quotes (WSQ) | 30 seconds | Near real-time |
| Snapshot (WSS) | 5 minutes | Moderate refresh |
| Minute bars (WSI) | 5 minutes | Intraday refresh |
| Ticks (WST) | 1 minute | High-frequency |
| Portfolio (WPF/WPS/WPD) | 5 minutes | Moderate refresh |
| Screening (WEQS) | 10 minutes | Moderate refresh |
| Estimates | 4 hours | Consensus updates infrequently |
| Historical (WSD) | 12 hours | End-of-day data stable |
| Macro data (EDB) | 24 hours | Periodic updates |
| Dataset (WSET) | 24 hours | Reference data |
| Sector (WSES/WSEE) | 24 hours | Rarely changes |
| Holders / Dates | 24 hours | Rarely changes |

All TTLs are configurable via `wind_mcp.toml` or environment variables. See [Configuration](#configuration).

## Configuration

Server behavior can be customized via `wind_mcp.toml` in the project root. All values can also be overridden via environment variables with the prefix `WIND_MCP_` (e.g., `WIND_MCP_CACHE_MAXSIZE=5000`).

```toml
[session]
connect_timeout = 30        # Seconds to wait for Wind connection
reconnect_retries = 3       # Auto-reconnect attempts
reconnect_backoff = 1.0     # Backoff multiplier between retries

[cache]
maxsize = 2000              # Max cached entries (LRU eviction)
ttl_realtime = 30           # WSQ — near real-time
ttl_snapshot = 300          # WSS — 5 min
ttl_historical = 43200     # WSD — 12 hours
ttl_dataset = 86400        # WSET — 24 hours
ttl_macro = 86400          # EDB — 24 hours
ttl_portfolio = 300        # WPF/WPS/WPD — 5 min

[api]
timeout = 30.0              # Per-call timeout (seconds)
retries = 2                 # Retry count on transient errors
backoff = 1.0               # Backoff multiplier

[log]
format = "text"             # "json" or "text"
level = "INFO"
```

## Installation

### Prerequisites

- **Windows** (WindPy is a Windows COM-based library)
- Python 3.10+ (must match Wind Terminal bitness — typically 64-bit)
- **Wind Financial Terminal (万得) running and logged in** (iWind or WFT)
- **WindPy** — installed via Wind Terminal, NOT via pip. Open Wind Terminal → click "Repair" or install the WindPy plugin from the Tools menu.

### Verify WindPy

Before installing Wind MCP, verify that WindPy works in your Python environment:

```python
python -c "from WindPy import w; w.start(); print(w.isconnected())"
# Should print: True
```

If this returns `False` or errors, fix your WindPy installation first. Common issues:
- Wind Terminal not running / not logged in
- Python bitness mismatch (e.g., 32-bit Python with 64-bit Wind)
- WindPy not installed (repair via Wind Terminal)

### Install

```bash
# From source
git clone https://github.com/QmQsun/Wind-MCP.git
cd Wind-MCP
pip install .            # standard install
# or: pip install -e .   # editable mode (for development)

# Or from PyPI
pip install wind-mcp
```

### Configure Claude Code

Add a `.mcp.json` file to register the MCP server. Two options:

**Global** (all projects can use Wind MCP) — place at `~/.mcp.json` (i.e., `C:\Users\<you>\.mcp.json`):

```json
{
  "mcpServers": {
    "wind-mcp": {
      "command": "wind-mcp",
      "args": []
    }
  }
}
```

**Project-level** (only one project) — place `.mcp.json` in the project root directory.

> The `wind-mcp` command is the console entry point installed by pip. Alternatively, use `"command": "python", "args": ["-m", "wind_mcp.server"]`.

## Quick Start

### As an MCP Server

```bash
# stdio (default — for Claude Code)
python -m wind_mcp.server

# HTTP transport (for web clients)
python -m wind_mcp.server --http --port=8080

# SSE transport (for streaming clients)
python -m wind_mcp.server --sse --port=8080
```

### Windows

```bash
# Command Prompt
run_server.bat

# PowerShell
.\run_server.ps1
```
