What it does

Habr Career's official OAuth API is read-only, so the server writes the way a browser does: through Rails forms with a CSRF token and the user's session cookie. Its tools let you check whether the cookie is still valid, fetch the HTML or JSON of any profile page with scripts and styles stripped out, parse a form's schema with current values and options, submit only the fields you want while leaving the rest untouched, and ask the user a clarifying question via elicitation. A submit response is explicitly marked SAVED or NOT SAVED with a reason, because Rails returns validation errors with an HTTP 200 status.

Who it is for. For people who want to update their own Habr Career profile through an agent instead of filling out forms on the site by hand.

Good fit when

  • You want to quickly update salary expectations, skills or job search status in your profile
  • You need to see what fields a specific profile form has before changing it
  • You want to change one field without touching the rest of the profile

Not a fit when

  • You need access to someone else's profile: the server only works with the account owner's own session cookie
  • You want profile access without a browser cookie: the official API is read-only for that

Environment variables

HABR_COOKIE required, secret
The _career_session and remember_user_token cookies from the browser, granting access to the user's account.

Limitations

The project has a single author, no license or releases, and requires manually pulling the _career_session and remember_user_token cookies from browser DevTools. The cookie is valid for a limited time, roughly until September per the author, after which the server reports an anonymous status and the cookie must be refreshed by hand. There is deliberately no typed resume-creation tool; the page itself is used as the schema.

How to disable. Remove the habr entry from your MCP client config and, if needed, revoke the Habr Career session on the site.

FAQ

Why doesn't the server use the official Habr Career API?

The official OAuth API is read-only, and profile changes are only possible through web forms, so the server mimics browser behavior with a CSRF token.

Can changing one field accidentally wipe other profile data?

No, habr_submit only sends the fields you pass and resends the rest as they are, including Vue-driven fields like skills and languages.

README in short

The README explains why a session cookie is needed instead of the official API, gives commands for obtaining and checking the cookie and wiring the server into an MCP client. It describes four tools: session check, page read, form parsing and field submission with an explicit save status. It ends with a list of tests, some of which need a real account and change a live profile.
