A small connection. More possibility.

Your AI gets a better set of tools.

The Model Context Protocol (MCP) lets an AI client use external tools, prompts and reference material.

Diffyn runs locally, giving compatible clients ways to adapt communication to your stated preferences.

Your connection notebook

Make a little space.

Rust 1.99+ and a client that supports local stdio MCP.

A fresh start

Three small steps.

  1. Install Diffyn.

    Run the installation command to build the tagged release with Cargo.

    Install Rust first if you need it ↗
  2. Set the executable path.

    Replace the example command with your executable's absolute path.

    Cargo usually installs to ~/.cargo/bin/diffyn; Windows uses diffyn.exe.

  3. Connect your client.

    Reload its MCP configuration, then discover the tools, prompts and guides.

Read the connection guide ↗

1. Install

cargo install --git https://github.com/nathcymru/Diffyn --tag v2.0.3 --locked diffyn

Requires the published v2.0.3 tag. Downloads dependencies during installation.

2. Connect

{
  "mcpServers": {
    "diffyn": {
      "command": "/absolute/path/to/diffyn",
      "args": []
    }
  }
}

Replace the path. Syntax varies by client.

Local stdio only. Hosted HTTP clients need a different transport.

You can select and copy the commands directly.

Different + Diffinio

Your mind. Your meaning.
Your way.

No diagnosis needed. Your expressed preferences come first.

Diffyn’s local tools preserve source information and make changes visible for review.

Why sunflowers?

Sunflowers remind us that not every disability is visible. There is space here for needs that others may not see.

Diffyn is an engineering project, not a diagnostic or clinically validated intervention. Your AI client's data policies still apply. Research and limits.
