tax MCP servers: questions people ask
What's the most popular MCP server for tax?
On GitHub stars, Korea Tax Calculator (★ 85), Australian Tax MCP (★ 14) and Korea Tax Law (★ 5) lead the 121 we list. Korea Tax Calculator is named for tax and passed every check we run.
Are tax MCP servers safe to install?
117 of the 121 passed every registry check. Reading the package code or tool descriptions of 99 of them turned up 3 with something to look at, from install scripts to obfuscated code. A clean result means none of our patterns matched, not that a server is safe.
Hosted or local: how do tax MCP servers run?
79 can run hosted, so you only paste a URL into Claude, Cursor or VS Code. The 48 that run locally ship as 27 npm, 20 PyPI and 1 MCPB bundle packages.
How do I install Korea Tax Calculator in Claude Code?

}
}. Its page has the config for other clients too.
