MCP server for validating and generating SOUL.md agent identity files from Claude Desktop.
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.
Installation
In SourceWeft
- Open Soul Mcp Server in the dashboard and add it to a workspace.
- 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.

Score
50% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
- Reached in the last 30 days25 pts
Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
- Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
- Tools listed15 pts
Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
