The tax intelligence layer behind SignalsHQ,
callable as infrastructure
For firms with in-house developers who want specific capabilities inside the tools they already build. Not the full workflow. Just the layer underneath it.
INTEGRATION
Two ways in.
Early Access
MCP servers
Drop directly into Claude, GPT-based coding agents, or an internal copilot your team is already building. Most teams are calling a capability within minutes of getting access.
Coming Soon
REST API
For systems that aren’t running an MCP-compatible client yet. Same capabilities, plain HTTP.
FOUR MCP SERVERS
What you can call
Early Access
Tax Engine MCP
tax_engine.compute()
Send client return data in. Get a computed return back, with gaps and issues flagged before they become a problem in review.
Firms using the underlying engine see 70% less time spent in prep.
Early Access
Document OCR MCP
document_ocr.extract()
Feed it the documents that break most OCR: P&L statements, K-1s with K-3s and footnotes, consolidated 1099s, rental income schedules. Get structured, usable data out.
98%+ extraction accuracy on complex tax documents.
Early Access
Advisory MCP
advisory.match()
Send client data in. Get back advisory opportunities, but only from a list your firm controls and approves. Not open-ended AI advice. Nothing surfaces that your firm hasn’t already signed off on as a valid opportunity type.
Coming Soon
Intake MCP
intake.collect()
Client document and data intake as its own callable layer, the front door to everything above it.
Secure Conversations. Smarter Tax Strategies.
Built on industry-leading standards to keep your clients' data safe and your firm audit-ready.
End-to-end Encryption
Monitoring Systems
Quarterly scans & annual pen tests
