Overview

AI-generated overview

Local MCP server for validating, generating and scoring SOUL.md agent identity files, usable from Claude Desktop.

What you can do
Validate a .soul.md file at a given path against the SOUL.md schema, returning pass status, name, version and errors. Generate a starter soul template from an agent name and optional keywords. Score a soul file from 0 to 100 by filled optional fields, listing filled and missing ones.
When to use it
Use it while writing or maintaining SOUL.md agent identity files and wanting to check their format, draft a starter file, or gauge completeness from Claude Desktop or another MCP client.
Requirements
Runs locally via npx from the npm package soul-mcp-server and must be registered in the MCP client configuration; desktop only. The validate and score tools need a local path to a soul file.
Before you install
The validate and score tools read local files at the path you give, so point them only at content you are comfortable reading. The README mentions deploying a soul file as a live agent, but that deployment is not one of the server's tools.

Installation

In SourceWeft

  1. Open Soul Mcp Server in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
