post_v1_legal_filings

CreateLegalFiling records a filing of one or more of the org's documents with a state or agency, and returns the tracking record.

It is a TRACKING record, not an autonomous filing. With no filing partner wired the honest status is "manual" and the note says so: the documents were generated for signature, and the org files them through its registered agent. Nothing here invents a filing id it does not have.

Every document id must belong to the caller's org; one that does not is a 404 naming it, so a filing can never reach across tenants.

Arguments

tools/list declares a type and a description for each field and nothing further. A — means neither the door nor that operation constrains the field.

Call it

A tools/call carries every argument in one flat object — nothing binds to a path or a query string. Nothing above is required, so every declared argument is shown rather than a guess at which matter.

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "post_v1_legal_filings",
         "arguments": {
           "documentIds": [
             "<documentIds>"
           ],
           "jurisdiction": "<jurisdiction>"
         }
       }
     }'

Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing.
