After approving with Google, the redirect to `https://app.tavily.com/api/mcp_account_creation?session_token=...&state=...` is blocked by CloudFront/WAF with a generic 403 \"Request blocked\" page before it reaches the app.\n\nRoot cause: the `session_token` JWT embeds the user's Google `picture` claim.

"Title": "Server is missing an `instructions` field, leaving agents with no guidance on which tool to use or how they combine",
"Excerpt": "`tavily-mcp` advertises five overlapping tools (`tavily_search`, `tavily_research`, `tavily_extract`, `tavily_crawl`, `tavily_map`) but provides **no server-level `instructions`** and **no resources/prompts**. The only guidance available is five isolated per-tool descriptions. As a result, agents frequently pick the wrong tool or misuse tools (especially `tavily_extract` and `tavily_research`), because nothing tells them *which* tool to start with or *how the tools combine*.\n\n### Tested version\n",
