update-investor

Overview

Partially update an existing investor. Only fields provided are modified — this is a partial update, not a replacement. First resolve the investor ID, collect what to change, then call the update tool.

Step 1 — Resolve the investor ID

If the user provided an investor ID directly, use it and skip to Step 3.

If only a name or description was given, search first:

mcp__carta_crm__search_investors({ query: "<name>", limit: 10 })

If multiple investors match, present the list and ask the user to confirm which one to update (show name and ID for each).

Step 2 — Collect what to update

Ask the user what they want to change:

• name — investor firm name
• fields — custom field values keyed by field ID (e.g. website, location, industry, about, tags)

If the user wants to update custom fields but isn't sure of field IDs, fetch the schema first:

mcp__carta_crm__get_investor_custom_fields()

If the user has already specified what to change in their message, extract it directly without re-asking.

Important: Only include fields that are explicitly being changed. Omit everything else.

Step 3 — Update the investor

Call:

mcp__carta_crm__update_investor({
  id: "<investor id>",
  name: "<updated name>",
  fields: {
    "<field_id>": "<value>"
  }
})

Omit name if it is not being changed. Omit fields if no custom fields are changing. Only include the specific keys within fields that are being updated.

Step 4 — Report result

On success, respond with a summary of what changed:

"Investor {name} updated (ID: {id}). Changed: [list of changed fields]"

On error, show the error message and suggest:

• Verify the investor ID is correct — run /search-investors to find it
• Check that custom field IDs are valid

Updating multiple investors

If the user wants to apply the same change to multiple investors, repeat Steps 1 and 3–4 for each. Summarize at the end:

"Updated N investors: [list of names]"
