[![PreReason/mcp MCP server](https://glama.ai/mcp/servers/PreReason/mcp/badges/score.svg)](https://glama.ai/mcp/servers/PreReason/mcp)

MCP server for [PreReason](https://www.prereason.com) — the Context API for financial agents.

PreReason returns pre-reasoned market briefings: trend signals, regime classification, confidence scores, cross-asset correlations, and causal narratives. Use it when your agent needs to reason about market conditions, not parse raw price feeds.

## Quick Start

### Option 1: Direct HTTP (Claude Code, Cursor, Windsurf, etc.)

Clients that support remote MCP servers can connect directly with no bridge package needed.

```bash
# Claude Code (CLI one-liner)
claude mcp add prereason --transport http https://api.prereason.com/api/mcp
```

Or add to `.mcp.json` / your client's MCP config:

```json
{
  "mcpServers": {
    "prereason": {
      "type": "http",
      "url": "https://api.prereason.com/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}
```

### Option 2: stdio bridge (Claude Desktop and other stdio-only clients)

**Requires [Node.js 18+](https://nodejs.org)**

Add to your MCP client config (e.g. `claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "prereason": {
      "command": "npx",
      "args": ["-y", "@prereason/mcp"],
      "env": {
        "PREREASON_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}
```

Claude Desktop config file location:
- **macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows:** `%APPDATA%\Claude\claude_desktop_config.json`

Restart your MCP client after editing the config. PreReason should appear with 5 tools.
