What you get

Tax season is stressful. You're juggling W-2s, 1099s, deductions, credits, and trying to figure out if you should itemize or take the standard deduction. You Google "SALT deduction limit 2025" and get 10 conflicting articles.

Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
