Upstash Context7 2.3.0 adds authentication prompts for anonymous users who exceed per-IP search thresholds. This feature applies to MCP server and CLI interactions.

Why it matters: Anonymous users exceeding per-IP search thresholds now encounter sign-in prompts. Review rate-limit configuration to align behavior with your API design goals.

Full changelog

Minor Changes

  • 34fda7d: Prompt anonymous users to sign in. After the backend signals (via the X-Context7-Auth-Prompt: 1 response header on /v2/libs/search or /v2/context) that an anonymous client has crossed the per-IP threshold, the MCP server appends a one-time sign-in invitation to the tool result.
    • Both stdio and HTTP transports surface the same nudge: a tool-result notice asking the assistant to run npx ctx7 setup --<client> --mcp -y (with --stdio appended when the MCP server is running on stdio) after explicit user confirmation. The CLI handles OAuth and writes credentials into the MCP client's config; the user restarts their MCP server / editor to pick up the new credentials.
    • Detects the calling client from X-Context7-Client-IDE / User-Agent and selects the matching CLI flag (--cursor, --claude, --codex, --opencode, --gemini); falls back to interactive setup when unknown.
    • HTTP transport remains stateless — the threshold is tracked by the backend (per-IP, 24h TTL), the MCP server only reacts to the signal.
