How to connect Tax Calc
Tax Calc runs locally from an MCP Bundle: a single downloadable archive holding a local server and a manifest that describes it: https://github.com/theluckystrike/mcp-servers/releases/download/v0.22.0/tax-calc.mcpb version 0.22.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs a client that installs MCP Bundles; the file is opened in, or added to, that client.
