AI-generated overview

Read-only lookup of witness and spousal-consent signature request status on equity awards via Carta.

What it does
Queries Carta cap-table data through MCP tools to report the status of witness and spousal-consent signature requests tied to option grants, RSAs, and PIUs. It covers a single award, one company, or a whole portfolio, and returns each request's type, status, deadline, award reference, and the person who needs to sign. Results are presented as a table led by counts of awaiting-signature, signed, and expired requests, with a suggested next step. The skill is read-only and cannot add details, send reminders, or extend deadlines.
When to use it
Use it when asked whether a witness or spouse has signed an award, who still needs to sign, which signature requests are awaiting signature or expired, or when a signing link expires. It suits questions about a single award, a company, or a portfolio of companies.
Requirements
Requires the Carta MCP tools (call_tool, list_contexts, set_context, list_accounts) and an AskUserQuestion tool for missing inputs. Needs a corporation_id or portfolio_id, and for a single award a security_type and security_id. No scripts are shipped; instructions only.

Witness & Spousal-Consent Signatures

Show the status of the extra signatures some equity awards need before they're fully in place.

Background

When someone is granted equity, the award sometimes needs a signature from a person other than the recipient before it's complete:

  • Witness — an independent person who confirms they watched the recipient sign. This is a legal requirement in some markets.
  • Spousal consent — the recipient's spouse signs to acknowledge the award. This applies where local marital-property rules give a spouse an interest in equity earned during the marriage.

Each one is tracked as a signature request tied to a single award. A request moves through these stages:

StageWhat it means
Awaiting detailsThe request exists, but the witness or spouse's name and email haven't been added yet.
Awaiting signatureDetails are in and the signing link has been sent. Waiting on the witness or spouse to sign.
SignedDone — the witness or spouse has signed.
ExpiredThe signing link's deadline passed before it was signed. Signing links expire about 30 days after they're sent.

These three awards can carry signature requests: option grants, RSAS (restricted stock awards), and PIUs (profits interest units).

When to Use

  • "Did the witness sign Jordan's option grant?"
  • "Which grants are still waiting on a signature?"
  • "Is the spousal consent done for this award?"
  • "Show me any expired signing links for this company."
  • "List the outstanding witness signatures across my portfolio."

Prerequisites

  • One company or one award → you need the company. Get it from list_accounts (companies appear as corporation_pk: entries).
  • A single award → you also need its type (OPTION_GRANT, RSA, or PIU) and the award itself. The company-wide list (below) returns these, so start there if you don't already know which award you mean.
  • A portfolio → you need the portfolio. Get it from list_accounts (portfolios appear as organization_pk: entries) — this is the investor or firm view across the companies they hold or manage.

If a required input is missing, ask for it with AskUserQuestion before fetching (see carta-interaction-reference §4.1).

Data Retrieval

Pick the command that matches the scope of the question.

One company — every request for a single company:

call_tool({"name": "cap_table__list__witness_signatures_for_corporation", "arguments": {"corporation_id": corporation_id}})

Optional filters: request_type (WITNESS or SPOUSAL_CONSENT), status (a list of PENDING, FILLED, SIGNED, EXPIRED), page, page_size.

One award — every request on a single award you've already identified:

call_tool({"name": "cap_table__get__witness_signatures_for_security", "arguments": {"corporation_id": corporation_id, "security_type": "OPTION_GRANT", "security_id": security_id}})

security_type is one of OPTION_GRANT, RSA, PIU.

A portfolio — requests across every company in a portfolio:

call_tool({"name": "cap_table__list__witness_signatures_for_portfolio", "arguments": {"portfolio_id": portfolio_id}})

Optional filters: request_type, status, issuer_id (narrow to one company), page, page_size.

Spousal consent in portfolio view: the portfolio list returns witness requests only, unless you narrow it to a single company with issuer_id. Spousal-consent requests appear only for a single company that has the feature turned on. If a user asks about spousal consent across a whole portfolio, narrow to one company at a time.

Default status filter: when you don't pass status, the results show the requests that usually need attention — those awaiting signature and those that have expired. To see requests still awaiting details or already signed, pass status explicitly (e.g. "status": ["SIGNED"]).

Key Fields

Each request carries:

  • status: PENDING, FILLED, SIGNED, or EXPIRED — map to the friendly labels in the Background table.
  • request_type: WITNESS or SPOUSAL_CONSENT.
  • expires_at: the signing deadline.
  • issuer_name: the company that granted the award.
  • security_label: the award's reference (for example, "ES-1007").
  • security_type: OPTION_GRANT, RSA, or PIU.
  • witness_name, witness_email: the witness or spouse who needs to sign (blank until details are added).
  • acceptance_date: when the recipient accepted the award.

Gates

Required inputs: a company (corporation_id) for the company and award commands; a portfolio (portfolio_id) for the portfolio command; plus security_type and the award for the single-award command. If missing, call AskUserQuestion before proceeding.

Presentation

Format: Table.

BLUF lead: Lead with the counts — how many are awaiting signature, signed, and expired — then the table.

4 signature requests: 2 awaiting signature, 1 signed, 1 expired.

Translate codes to plain language. Never show the raw status, type, or any internal reference. Use "Awaiting signature", "Witness" / "Spousal consent", and "Option grant" / "RSA" / "PIU". Identify each request by company, award reference, and the person's name — not by any internal number.

Sort order: Awaiting signature first, then by soonest deadline; expired next; signed last.

Date format: MMM d, yyyy (e.g. "Jan 15, 2026").

CompanyAwardTypeNeeds to signStatusDeadline

For a single award, lead with the award and the count, then list its requests.

End with a next step — for example, point out which requests are closest to expiring, or note that reminders and deadline extensions are handled in Carta.

Caveats

  • Read-only: this skill can't add details, send reminders, or extend deadlines — those are done in Carta.

Carta Fund Admin Requests

carta

Send work to your Carta Fund Admin team and track it. Opens a request the team reads, acts on, and replies to — the off-ramp for anything no other Carta skill or command can do. TRIGGER: "ask Carta to", "have Carta do", "send this to my fund admin", "ask my fund admin team", "can Carta do this for me", "check on my request", "did Carta reply", "what requests do I have open", "reply to Carta", "follow up on my request", plus ANY action request (create/change/send/restate/reconcile/split/fix) that no other skill or Carta command covers. NOT FOR: reporting a bug or feature request about this plugin (call fa:create:feedback directly); questions answerable from Carta data (use carta-explore-data); capital call reminders to LPs (that is a Carta command, not a Fund Admin request).
