See what an agent can do with Carta before you ever sign up. Pick a story: recorded sessions replay real probe-harness transcripts; commands tagged live-capable can re-run against the real endpoint from our edge, right now (▶ run live — the exact same request, live and recorded lines always labeled); the live MCP handshake runs real requests from our edge, right now — including, where the server allows it, one real read-only tool call (bring your own key for auth-gated servers); sandboxed self-drive sessions are designed and gated (docs/TRY-IT.md).

Fundraising modeling — stories about fundraising modeling in this arenaModel a priced round — dilution, option pool top-up, SAFE conversion, pro-forma ownership — and share the scenario with counsel and investors
nonemoves PA Scoreimpact 30
The evidence pack covers Carta's developer/API platform (cap table data retrieval, OAuth, MCP plugins, data warehouse) but contains no documentation of a scenario-modeling tool for priced rounds, dilution, option pool top-ups, SAFE conversion modeling, or pro-forma ownership sharing with counsel/investors.
Agenticness — how well agents can access and operate the productPoint an agent at llms.txt or agent-oriented docs
nonemoves agent-readyimpact 30
Direct probes show no llms.txt file (404) and no machine-readable docs or OpenAPI spec discoverable at expected paths, meaning there's no agent-oriented docs entrypoint for an AI agent to point at; the MCP setup guide is a separate integration path, not an llms.txt/agent-docs format.
Agenticness — how well agents can access and operate the productSet up automations that run autonomously in the background
nonemoves Built-in AIimpact 30
Carta's docs describe API/OAuth access and an MCP integration for querying cap table and fund data via natural language (carta-docs-9, carta-docs-30, carta-docs-31), but there is no evidence of scheduling, triggers, webhooks, or any mechanism for autonomous background-running automations built on the platform.

Missing: any mention of a CLI, command-line tool, or terminal-based interface.

nonemoves agent-readyimpact 30
No evidence in the pack mentions webhooks, event subscriptions, or push notifications anywhere in Carta's API platform docs; the documented capabilities are REST endpoints, OAuth flows, MCP/Claude plugins, and a data warehouse, none of which describe webhook subscription support.
