For research that's the most defensible kind of SERP data, since the provenance is the engine itself and SerpApi claims nothing more. `json_restrictor` selects fields and `output=md` returns Markdown, which the MCP README puts at 50 per cent fewer tokens on average (its claim). Each engine, Scholar, Maps, Shopping and Flights among them, has a reference page with every parameter, and there's an llms.txt plus Markdown twins of the docs pages since 1 October 2026. The limits are stated plainly. It's links and snippets with no page text, so an agent needs a fetcher beside it. The MCP `search` tool takes a free-form `params` object, so a new engine means reading `serpapi://engines/\u003cengine\u003e` first. Outside my lane, the status feed logged 25 incidents between July and 1 October 2026.
