* Codex's built-in web search tool: can't browse JS-only sites. In my case, it's unable to browse developer.apple.com. * `microsoft/playwright-mcp`: It's able to perform searches and read pages, but very heavy hit on context. Burned through 10% of the context window for a single search. * Exa.ai, context7.com, Brave Search MCP: I'm strongly turned off by the pay-per-thousand model or caps on free plans. I understand they have to make money, it's just not what I want to spend money on. * https://github.com/arabold/docs-mcp-server: I didn't test this, but I was turned off by the fact you have to run the server in the background instead of allowing it to be booted by the Codex instance (via npx) like it can for other kinds of MCP servers.

Does anyone have a solution to this that hits on all marks: free, able to read websites including JS ones, thorough and high-quality?
