Operationput_legal_templates_by_id
AuthAuthorization: Bearer $HANZO_API_KEY

Saves the org's own version of a template — a custom NDA, a house MSA — and returns it with its new version number. It takes effect for that org only; other orgs keep the built-in.

Two boundaries cannot be crossed here. Overriding a built-in INHERITS its category and its counsel-review posture, which can be raised but never dropped; and a formation or equity template is counsel-review whatever the caller sends, so no org can generate a securities-class document without the notice.

The body is validated on save, not at generation: a template that references an UNDECLARED merge field is refused with 400 rather than stored and rendered blank into a contract months later.

Request

9 fields, body application/json (required).

MCP reaches legal through the legal tool, which names its 10 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_legal_documents"
         }
       }
     }'
