### Description (declared)

# Pyke MCP Server

An MCP (Model Context Protocol) server for the [Pyke](https://pyke.sourceforge.net/) logic programming inference engine. This server enables LLMs to perform logical reasoning through knowledge bases with facts, rules, and queries.

## Features

- **Fact Management**: Add ground truth facts to the knowledge base
- **Rule Definition**: Define inference rules using forward chaining
- **Query Execution**: Check if facts can be derived from the knowledge base
- **Goal Proving**: Find all variable bindings that satisfy a goal
- **Session Management**: Support multiple independent knowledge bases
- **Logic-LLM Compatible**: Load programs in Logic-LLM format

## Installation

### Using pip

```bash
pip install git+https://github.com/evertrol/pyke3 pyke-mcp
```

### From source

```bash
git clone https://github.com/NewJerseyStyle/pyke-mcp.git
cd pyke-mcp
pip install -e .
```

### Dependencies

- Python 3.10+
- `mcp>=1.2.0`
- `pyke>=1.1.1` (Install from source by `pip install git+https://github.com/evertrol/pyke3` but the package name is `pyke` not `pyke3`)

## Quick Start

### Running the Server

```bash
# Using the installed command
pyke-mcp

# Or using Python
python -m pyke_mcp.server
```

### Configuration for Claude Desktop

Add to your `claude_desktop_config.json`:

**macOS/Linux:**
```json
{
  "mcpServers": {
    "pyke": {
      "command": "pyke-mcp"
    }
  }
}
```

**Windows:**
```json
{
  "mcpServers": {
    "pyke": {
      "command": "pyke-mcp"
    }
  }
}
```

Or with explicit Python path:

```json
{
  "mcpServers": {
    "pyke": {
      "command": "python",
      "args": ["-m", "pyke_mcp.server"]
    }
  }
}
```

## Available Tools

### `add_fact`
Add a fact to the knowledge base.

```
Predicate(arg1, arg2, ...)
```

**Examples:**
- `Human(Socrates, True)` - Socrates is human
- `Parent(John, Mary)` - John is a parent of Mary

### `add_rule`
Add an inference rule using forward chaining.
