get_review
Fetch a Cobalt Capture review by its share link or slug. Returns the reviewer's notes as text AND each annotated screenshot as an image, so you can see exactly what was marked and what to change.
create_review
Start a new Cobalt Capture review and get a handle for filling it in. Use this to compile the findings of any site study — a usability pass, a pricing teardown, a positioning audit, a QA run — into one shareable, durable report with real…
add_screenshot

replace_screenshot
Overwrite one existing screenshot in a review with a new capture, in the same position. Destructive: the old image and any pins or annotations on it are removed and cannot be recovered; the title and comment change only if new ones are…
add_note
Append a free-standing text note (not tied to a screenshot) to a review created by create_review. Use for context, steps taken, or a summary of findings between screenshots.
update_review
Set or replace a review's summary and/or title. The summary is shown at the top of the review, above every screenshot and note. Replaces any existing summary or title.

Create a temporary email inbox for testing the signup or email flow of a product the user owns or is authorised to test, within that product's terms. Returns an `address` to enter in the product's form and an `inbox_token` for reading it…
check_inbox
Read mail delivered to an inbox from create_inbox, newest first, for example a verification code or confirmation link from the signup email of the product being tested. Requires the inbox_token, so only whoever created the inbox can read…
email_review
Email a link to a review to the person who ran the study. Sends only to an address that belongs to a verified Cobalt account (other addresses are refused, which keeps the tool from being used to send unsolicited mail). The email contains…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "cobalt": {
      "type": "http",
      "url": "https://cobaltcapture.com/mcp"
    }
  }
}

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
