get_v1_captable_summary

GetSummary computes the caller org's cap table. It answers who owns what on a fully-diluted basis: outstanding shares, granted options, per-stakeholder ownership percentages, each share class's authorized versus issued position, and the capital sitting on SAFEs and convertible notes that have not yet converted. Only non-terminal option grants dilute — EXERCISED, EXPIRED and CANCELLED grants are excluded, so equity issued through an exercised option is never counted twice.

Call it

A tools/call carries its arguments in one flat object. This tool declares none, so the object is empty.

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. How to get a key →
