Connect the MCP through OAuth or the `X-MCP-Token` header, not the registry's `?token=` URL\n3. Call the REST API with `engine=` when context is tight. The MCP loads over 100 tool definitions\n4. Page Google results with `page`. `num` is fixed at 10\n5. Pace bursts. One hour can use at most 20 per cent of the plan's monthly searches\n\n### Valyu\n\n1. Set `max_price` and `max_num_results` on every search to bound cost\n2. Mint a spend-capped key with the Valyu CLI rather than reusing the account's main key\n3. Call `valyu_search`. The legacy per-vertical MCP tools stop working on 2026-12-01\n4. A 206 means some sources failed. Check which before treating results as complete\n5. DeepResearch is async.
