Troubleshooting MCP

Fixes for the problems people hit when connecting: blocked sign-in, 401 errors, quota messages and missing tools.

Updated 1 October 2026Open in DocStoX
The sign-in window does not open

Your browser blocked the pop-up. Allow pop-ups for chatgpt.com or claude.ai and click Connect again. Sign-in always happens on a docstox.com page; if you see anything else, stop.

"This connection was revoked" or a 401 error

The app or key was revoked at /mcp/keys. For a connected app, disconnect DocStoX in the client and connect again (in Claude Code: /mcp, Clear authentication, then Authenticate). For an API key, create a new one at /mcp/keys and replace it in your config. A 401 also appears if the header is missing its Bearer prefix, or the key does not start with dox-.

"DocStoX MCP quota exceeded"

You reached your daily or 30-day allowance. The daily count resets at 00:00 UTC (05:30 IST). See exactly what was used at /mcp/keys, or raise the limit with Pro. Full detail: Usage and limits.

A tool answers with a Pro explanation instead of data

That tool is part of DocStoX Pro. The call is not counted against your allowance. The pricing page lists what Pro includes.

The tools do not show up

Check the URL is exactly https://mcp.docstox.com/mcp (with /mcp at the end), then restart or reload the client. Most clients have an /mcp command or an MCP settings list that shows whether DocStoX connected:

  • Claude Code, Codex, Gemini CLI: type /mcp in the terminal.
  • Claude (web/desktop): Customize → Connectors, or the + menu → Connectors in a chat.
  • ChatGPT: the + menu → Developer mode in a chat.
  • Cursor, Windsurf, VS Code: the client's own MCP servers list, where DocStoX shows its tool count when connected.
"This DocStoX account is disabled"

Your account was disabled. Contact [email protected] (opens in a new tab) if you think this is a mistake.

Your Google account's email address is not verified

DocStoX only signs in a Google account whose email Google has verified. Verify the email address with Google, then reconnect DocStoX.

Still stuck

The general Troubleshooting page covers account and billing issues outside MCP. For anything else, write to [email protected] (opens in a new tab) and say which client you are using and what you saw.
