### Description (declared)

# catapult-mcp

MCP server for querying heterogeneous catalysis databases. Exposes reaction data, catalysts, and conditions via the Model Context Protocol.

## Features

- **Reaction search** — query by catalyst, reactant, product, or conditions
- **SQLAlchemy backend** — SQLite (default) or PostgreSQL
- **MCP protocol** — compatible with any MCP-aware LLM client

## Installation
