Keenable: independent web-search API for agents, 100K free requests
Its own crawler and 100B-doc index give agents Google-free search via one MCP URL — as Codex extensions gain result rewriting and Okta gives agents identities.

Search without a Google key
Keenable exposes search_web_pages and fetch_page_content over an MCP server at api.keenable.ai/mcp, backed by its own 100B+ document index at under 250ms p95 (US East). New accounts get 100,000 free requests, then $4 per 1K pay-as-you-go or $1 per 1K at 100+ RPS — a Google/Bing-free search backend you can wire into an agent today.
Time Machine: search the web's past
An early-access Time Machine endpoint runs point-in-time searches over historical web snapshots, so a research or monitoring agent can ask what a page said last quarter, not just what it says now. Same index, a new axis — handy for diffing sources or tracking changes over time.
Codex extensions can rewrite MCP results
Codex v0.151.0 (Aug 29) lets extensions inspect or replace MCP tool results before they reach the model, and adds a configurable grace period for discovering tools from optional MCP servers. If you build on Codex, you can now filter, redact, or reshape what a tool returns mid-loop.
Elsewhere: Okta makes agents real identities
Okta's Agent SSO went generally available (Aug 24), treating AI agents as first-class identities in its Universal Directory with short-lived tokens and Cross App Access instead of hardcoded API keys. Deploy agents into an Okta shop and their credentials become governable and revocable.
