## [Runs, email checks and a Reports dashboard](https://proxymail.qa/changelog#2026-10-17)

  - NewAgents can check emails (`check_email`), count them (`count_emails`) and check that none arrive (`expect_no_email`): verdicts, never the email.
  - NewAgents can record a session as a run (`start_run`, `finish_run`) and get its report in Markdown, and borrow a test account in a known state from the pool (`check_out_account`, `return_account`).
  - NewPrompts for testing sign-up, password reset and code sign-in, and for auditing an app's account emails, each ending in a report.
  - New`form_values` gives an agent the value for each field of a sign-up form, and the `prepare_account` prompt gets a test account ready: it confirms the account's state in the app, makes one when none is free, and puts it back afterwards.
  - NewThe `auth_regression_pack` prompt checks sign-up, password reset and invitations the same way every time, including reused and replaced links, and its report says what changed since the last run. It's also an agent skill.
  - Improved`check_email` takes `expect_text` and `expect_language`, and the server tells agents plainly that Proxy Mail QA supplies the inbox and sign-up details while the agent signs up in the app.

## [The Team plan, new MCP tools and the npm package](https://proxymail.qa/changelog#2026-10-15)

  - New`set_password` saves the password a test account uses after the app changed or reset it, and `update_address` changes its name and username.
  - New`check_delivery` says what reached an address and what we refused, and `get_address_variants` lists unusual versions of it. Every tool accepts a variant.
  - New`create_address` takes an age or date of birth and a country, `list_addresses` finds earlier test accounts by tag, country, age, saved password or text, and `wait_for_link` can ask for the link that opens a mobile app.

## [See why an email didn't arrive](https://proxymail.qa/changelog#2026-10-13)

  - ImprovedEvery tool says whether it only reads, changes or deletes, so clients can ask you before the ones that change things.

4. 12 October 2026  
## [A REST API and an MCP server for tests and AI agents](https://proxymail.qa/changelog#2026-10-12)

  - NewThe MCP server at `api.proxymail.qa/mcp` gives coding agents their own test inboxes. Claude, ChatGPT, Claude Code, Cursor, GitHub Copilot and other clients sign in through the browser and choose a project, so no key is needed. See [MCP server](https://proxymail.qa/docs/mcp).
  - New`get_project` tells an agent the project's mail domains and limits, and `create_address` can make a password with the address and save it.
