Browserbase MCP Server
Vendor-built Browserbase MCP server combining cloud browser automation (Browserbase) with natural-language-to-action mapping (Stagehand). 6 tools: start, end, navigate, act, observe, extract. Available as a hosted endpoint at https://mcp.browserbase.com/mcp (LLM costs covered for Gemini) or self-hostable via @browserbasehq/mcp.
“Browserbase ships its MCP server as both a hosted service (`mcp.browserbase.com/mcp`) and a self-hosted npm package (`@browserbasehq/mcp`). The hosted version is the recommended path because Browserbase covers the LLM costs for Gemini, the best-performing model in Stagehand evals. The architectural decision: Browserbase runs headless Chrome in their cloud, and Stagehand provides the natural-language-to-browser-action layer (`act`, `observe`, `extract`). The result is an MCP that the agent uses with simple verbs while Browserbase handles the operational complexity of fleet-managed browsers, anti-bot measures, and session state. The trade-off is dependency: every action runs through Browserbase's infrastructure, with the cost and reliability characteristics that come with that. For teams already using Browserbase or Stagehand, the MCP integration is a thin layer over an existing investment. For teams starting fresh, it's worth weighing against running Puppeteer or Playwright locally.”

6 TOOLS AVAILABLE
OUR ASSESSMENT
- Hosted endpoint at https://mcp.browserbase.com/mcp eliminates local browser management; Browserbase covers the Gemini LLM costs for the natural-language layer.
- Stagehand integration provides high-level verbs (`act`, `observe`, `extract`) so the agent works at the intent layer above raw clicks and selectors.
- Vendor-built; the same team that operates the Browserbase fleet maintains the server.
- Self-hosted path available via npm or Docker for teams that need on-prem control.
- Hosted endpoint introduces a dependency on Browserbase's infrastructure; outages there affect every team using the recommended path.
- Self-hosted path requires Browserbase API key, project ID, and a model API key (Gemini, Claude, or other supported LLMs).
- Stagehand's natural-language layer is opinionated; teams used to selector-based automation may find the verb-level abstraction surprising in edge cases.
The hosted endpoint runs browser sessions inside Browserbase's cloud; data flows through Browserbase's infrastructure with their standard data-handling posture documented in Browserbase's policies. For self-hosted deployments, environment variables hold the Browserbase API key, project ID, and the LLM API key (Gemini by default). Stagehand sends page content to the configured LLM for natural-language reasoning; teams handling sensitive page data should evaluate which LLM endpoint receives that content. The MCP server itself runs in the operator's environment and uses standard MCP transport (SHTTP recommended).
Teams already running Browserbase or Stagehand, or teams who want fleet-managed cloud browser automation with Browserbase handling the headless Chrome operations.

SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 5 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 5 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
