Cobalt Capture is a remote MCP server that gives an AI agent 9 tools, among them add_note, add_screenshot, check_inbox. It answers at https://cobaltcapture.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 19 October 2026, succeeded.
Read or write a Cobalt Capture visual product review — notes plus annotated screenshots — over MCP.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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. Inputs: claim_token, review, text |
add_screenshot | Append a screenshot (with an optional note) to a review created by create_review. The image is stored durably in Cobalt — this is the way to persist screenshots that would otherwise be lost when they only pass through a browser tool. Call o Inputs: claim_token, comment, image, image_url, review, source_url |
check_inbox | Read mail delivered to an inbox from create_inbox — e.g. to pull a verification code or confirmation link out of a signup email. Returns newest-first. Mail usually lands within seconds; if the response is empty, wait a few seconds and call Inputs: address, format, inbox_token |
create_inbox | Create a disposable email inbox you can monitor, for signing up to the product you're testing. Returns an `address` to type into the signup form and an `inbox_token` to read it with. Use this instead of asking the human for an email account Inputs: review |
create_review | Start a new Cobalt Capture review and get a handle for filling it in. Use this to compile findings from a browser-testing or QA run into one shareable, durable report. Returns a `review` slug and a `claim_token` — pass BOTH back to add_scre Inputs: product_url, summary, title |
email_review | Email a link to a finished review to the human who started the run, so they don't have to remember to come back for it — useful at the end of a long unattended study. Pass the review, its claim_token, and the human's email. IMPORTANT: we on Inputs: claim_token, email, review |
get_playbook | Fetch a Cobalt test playbook by name and follow it exactly. Use this when the user asks for a usability pass, QA run, first-time-user review, or a positioning/messaging audit and you don't already have the playbook text. Available: 'usabili Inputs: name, url |
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. Inputs: review |
update_review | Update a review's summary and/or title after the fact. Use this at the END of a run to land the verdict at the TOP of the review: the headline findings don't exist until the work is done, but readers (and agents ingesting the review) want t Inputs: claim_token, review, summary, title |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://cobaltcapture.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 1 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
