MCP Server for Phext

An MCP (Model Context Protocol) server that provides access to phext - a hyperdimensional text processing system.

NOTE: We will be publishing this as a pip package soon. For now, please use the developer installation below.

Developer Installation

For developers who want to try the latest features:

1. Download the repository:

   git clone https://github.com/identimoji/mcp-server-phext.git
   cd mcp-server-phext

2. Install uv (if you haven't already, skip this if you have):

   curl -LsSf https://astral.sh/uv/install.sh | sh

3. Install dependencies:

   uv sync

4. Add to Claude Desktop config:

IMPORTANT: You'll need to add the full path to the repo you just downloaded here

{
  "mcpServers": {
    "phext-dev": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "{full path to your local mcp-server-phext repo}",
        "python",
        "-m",
        "mcp_server_phext"
      ],
      "env": {
        "PHEXT_DEFAULT_FILE": "~/.claude/claude_desktop.phext"
      }
    }
  }
}

5. In the project knowledge of Claude desktop, you can add "Start all conversations with initialize_phext()" ... this will inform Claude how to use Phext, and can be customized to have Claude Desktop automatically save memories, milestones, or whatever he wants to remember about your interactions! Just tell him what you want to be saved, and he can update the initialize script automatically for you.

What is Phext?

Phext is a hyperdimensional text coordinate system that allows you to organize and navigate text in three-dimensional space using coordinates like 1.1.1, 2.3.4, etc. It enables unique ways of structuring and accessing textual information.

Installation

# Install with uv (recommended)
uv add mcp-server-phext

# Or with pip
pip install mcp-server-phext

Usage

NOTE: Thes are instructions for once this mcp server is published to pip ... IGNORE FOR NOW, use above development install.

With Claude Desktop

Add this to your Claude Desktop configuration:

{
  "mcpServers": {
    "phext": {
      "command": "uv",
      "args": ["run", "mcp-server-phext"],
      "env": {
        "PHEXT_DEFAULT_FILE": "~/.claude/claude_desktop.phext"
      }
    }
  }
}

With Claude Code or other MCP clients

# Run the server directly
uv run mcp-server-phext

# Or with a specific default file
uv run mcp-server-phext --default-phext-file ~/my-phext-file.phext

Features

The MCP server provides the following tools:

Core Operations

• phext_fetch: Read content from a coordinate (e.g., 1.1.1/1.1.1/1.1.1)
• phext_insert: Insert content at a coordinate (appends to existing)
• phext_replace: Replace content at a coordinate
• phext_range_replace: Replace content across a range of coordinates
• phext_remove: Remove content at a coordinate

File Management

• phext_create_file: Create new phext files
• phext_explode: Get a map of all coordinates and content
• phext_textmap: Get a text summary of all coordinates
• phext_normalize: Clean up and optimize phext structure
• phext_merge: Merge two phext files together

Resources

• Access to phext files as MCP resources
• Read raw phext file content

Example Interactions

# Fetch content at coordinate
phext_fetch(coordinate="1.1.1/1.1.1/1.1.1")

# Insert content at a coordinate
phext_insert(coordinate="1.1.1/1.1.1/1.2.1", content="Hello, hyperdimensional world!")

# Replace content across a range
phext_range_replace(
    start_coordinate="1.1.1/1.1.1/1.1.1", 
    end_coordinate="1.1.1/1.1.1/1.1.5", 
    content="New content"
)

# Get a map of all content
phext_textmap()

Configuration

Environment Variables

• PHEXT_DEFAULT_FILE: Default phext file to use if none specified

Command Line Arguments

• --default-phext-file: Specify default phext file

Development
