Heu Mcp
Connects Claude to the HEU Legal e-signature API so you can manage legally binding documents across 180+ countries without leaving the conversation. You get 18 tools covering the full v1 API: create native HEU documents or upload PDFs, prompt signers, extract structured party data (names, tax IDs, SDI codes), read document text for summarization or clause analysis, and download signed PDFs to disk. The read tools let Claude analyze contract contents directly while download saves the physical file. Requires an Enterprise subscription for API access and at least one template already set up in your HEU account. All destructive operations ask for explicit confirmation before executing.
