Vulcanus MCP server

sunsatosolutions/Vulcanus

Generates a Git-versioned Markdown vault as project memory, then serves it over MCP. recall returns a project's capsule plus the read-next list and warns when the capsule is older than the decisions beneath it; search ranks by layer; writes are scoped — update_capsule replaces one named section rather than rewriting the file. A doctor tool validates that every link resolves and every project is reachable, so the memory fails loudly instead of rotting. Plain Markdown, Obsidian-compatible, no database. npx @sunsato/vulcanus
