agenttax-mcp
MCP server that tracks US sales-tax obligations for paid MCP tools and AI agents.
What it does
MCP server whose track_payment tool takes an amount and the buyer's US state and ZIP code and returns the sales tax owed, the rate and a compliance note, logged to an AgentTax account; other tools fetch state rates and set economic nexus. It runs with npx and needs an API key from the hosted AgentTax service (free tier, then paid plans). For developers who charge for MCP tools; US only.
Where it fits on the map
Not on the map: needs a paid service.
The map places maintained projects for a company tax department or a tax authority, without a demo or paid-service flag. Everything else stays on the list with its label.
