tokensave_doc
Companion Markdown documentation for a source file -- doc content, the files it covers, and a staleness signal
How to use it
Project documentation lists tokensave_doc for the Tokensave MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
