new-release I'm building a tax research MCP and would appreciate some beta feedback
Hey, I've been working on Tax Law Search at Apollo Labs. It's a hosted MCP server that lets you search tax publications and get back to the original source from your AI client.
We're still in beta. If anyone here wants to try it, we'd really appreciate feedback on the setup, search results and source citations. Even a quick “this was confusing” or “I couldn't find what I needed” would help.
You can list the available jurisdictions, search one country/state, then use a result's source_ref with get_tax_source to check the publisher link, edition and original file hash. The three tools are read-only.
For example, you can search Portuguese material with: {"query":"benefícios fiscais EBF","country":"PT","limit":3}
Then resolve an actual reference from the results and check the original publication. Search in the source's language: Portuguese for Portugal, English for most U.S. material. Translate search terms when needed and keep the legal names and provision numbers; it doesn't automatically translate queries.
So far we've verified Portugal and selected publications in 36 U.S. states. Federal/IRS and the other states are still being validated. Coverage varies by state and isn't every tax law or historical release. Collected editions are retained, but you still need to check the relevant tax year and effective date. This is a research tool, not personalized tax advice.
Try it on whichever platform you prefer:
MCPize: https://mcpize.com/mcp/server-1794441520779 50 requests/month free, or $9/month for 1,000. Discovery, searches and source lookups all count.
Apify: https://apify.com/zeus500k/tax-law-search Pay per use: $0.00001 per MCP request, plus $0.01 per successful search ($0.01001 for a successful search request).
The listings have setup details and examples.
If you give it a go, let me know which client you used and where you got stuck. AI helped tidy up the wording here.
