Getting started

Quickstart

Two paths: fetch cited tax rules in 30 seconds with no auth, or give your AI agent live tax tools through the connector.

There are two ways to start, depending on what you need. Neither takes more than a few minutes.

Path A — Try a rule bundle (open for evaluation)

Every published rule for a jurisdiction is available as a single markdown document from one public endpoint — open today for evaluation and AI-agent discovery. Embedding this in a product at commercial scale is a commercial relationship (talk to us); production access is moving to a keyed REST API (see the roadmap).

curl https://www.openaccountants.com/api/bundle/malta

That returns every published Malta skill — rates, thresholds, allowances, deadlines — as plain markdown, each figure cited to its source. The {jurisdiction} segment accepts a country name (malta) or an ISO code (MT, GB, DE, US, US-CA, CA-ON). The response carries an X-Skill-Count header, and a jurisdiction with no published skills returns 404.

Want the index first? /llms.txt is a plain-text quick-reference for AI agents, and /llms-full.txt lists every published skill grouped by jurisdiction, with its quality tier and tax year.

See the full HTTP API reference for the accountant directory and response details.

Path B — Give your AI agent live tax tools (sign in)

For an interactive agent that looks rules up on demand, computes rates, and plans cross-border situations, connect the OpenAccountants MCP server:

  1. Add the connector from /connect. It works with any MCP-compatible AI agent.
  2. Sign in — the MCP server is OAuth-gated, so tool calls run as your account.
  3. Your agent can now call the tools, starting with start to scope a request, then search_skills / get_skill for the cited rules and get_rates / compare_jurisdictions / plan_cross_border for numbers.

Rate limits are 60 requests/minute per IP and 1,000 requests/day per signed-in account. The complete, always-current tool list is in the MCP tool reference.
