Carta Cap Table
Answering a cap table question normally means clicking through Carta's web reports one screen at a time and re-assembling the numbers by hand. This plugin puts sixteen skills behind the Carta MCP server so you can ask for grants, stakeholders, SAFEs, 409A expiry, round history, or a waterfall scenario in one sentence and get the assembled answer back.

Install the plugin
Plugins install through Claude Code’s plugin marketplace. Two commands, no files to place by hand.
Install the carta-cap-table plugin. It installs through Claude Code only. If you're not Claude Code, stop and tell me.
/plugin marketplace add anthropics/knowledge-work-plugins
/plugin install carta-cap-table@knowledge-work-plugins
If you can't run slash lines, run these two lines in a shell instead:
claude plugin marketplace add anthropics/knowledge-work-plugins
claude plugin install carta-cap-table@knowledge-work-plugins
When both commands finish, confirm the carta-cap-table plugin is installed. Use /plugin, or run claude plugin list in a shell.
Then tell me to restart Claude Code so it picks up the new skills.- 1
Add the marketplace
Run this once in Claude Code. It registers the marketplace this plugin installs from (knowledge-work-plugins), so every plugin in it becomes installable.
/plugin marketplace add anthropics/knowledge-work-plugins - 2
Install the plugin
Installs this plugin and everything it bundles. Restart Claude Code afterwards so it picks the new skills up.
/plugin install carta-cap-table@knowledge-work-plugins
Carta publishes this plugin, and Anthropic distributes it in the
knowledge-work-plugins marketplace. We list it here because cap table work is
one of the jobs people come to this catalog looking for — we did not write it
and have not reviewed it.
The problem it goes after, in Carta’s own framing: answering cap table questions — grants, stakeholders, SAFEs, 409A expiry, waterfall scenarios — means clicking through Carta’s web reports one screen at a time and re-assembling the data by hand.
Every skill in it talks to Carta’s hosted MCP server, so the plugin is only useful once that connector is authorized against your Carta account. Beyond the straight lookups, the set covers compensation benchmarking and role matching, conversion math, round and valuation history, and report generation into Markdown or Excel.

MCP connectors it declares
Carta's hosted MCP server. The plugin's skills read cap table, grant, valuation and compensation data through it, so the plugin does nothing until it is connected and authorized against your Carta account.
