A hosted headless-browser service (sessions, proxies, stealth, session recording) with Stagehand, its natural-language browser automation layer, so agents can navigate, act on and extract from web pages that plain HTTP fetching cannot reach.

## Research notes
Verified 2026-09-07: POST of an MCP initialize to https://mcp.browserbase.com/mcp with no key returned HTTP 200 with a JSON-RPC result, serverInfo name "stagehand-api" (protocolVersion 2025-03-26); the control POST to /zzz-not-a-route returned 404. Initialize succeeds keyless and, per the docs, the key is enforced at tool-call time. The candidate row's proposed alternative category was mcp-infrastructure; it lands here because its GTM use is data collection, the same reasoning as Bright Data. One browser hour a month on Free is a demo allowance, not a working allowance. 2026-09-07: https://mcp.browserbase.com/mcp returned 200 with a JSON-RPC initialize result to an MCP initialize POST (https://mcp.browserbase.com/mcp). 2026-09-09 (P6-04 repo sweep): first-party server source recorded at https://github.com/browserbase/mcp-server-browserbase, 3,404 stars. GitHub reports the repository ARCHIVED with its last push on 2026-07-20, so the source is readable but frozen; the hosted endpoint in mcp_url is the live surface. Evidence that it is Browserbase's own: the official MCP registry entry io.github.browserbase/mcp-server-browserbase carries that repository URL, npm @browserbasehq/mcp declares the same repository, and the org browserbase lists browserbase.com as its site.
