What Peek does

According to its repository: “Record your authenticated browser session (rrweb DOM, console, network) to local SQLite with PII masking, so coding agents can query it or drive the browser.”

The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Peek is listed under Browser automation, a category of 109 servers in the directory, where it ranks #95 by stars.

Topics declared by the repository: ai-coding-agent, apache-2, chrome-extension, claude-code, cursor, cypress.

Installing and connecting Peek

Distribution modes declared in the official MCP registry:

  • npm package (Node.js, usually started with npx)

It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: TypeScript.

Security: what to check

Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.

Points found for Peek:

  • System access: the Browser automation category gives the agent control over files, a terminal, code or a browser. A booby-trapped instruction in content the agent reads (prompt injection) can then turn into an action.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on May 26, 2026, the Cubenest/rrweb-stack repository has 8 stars and 0 forks, with 1 open issues. It has more stars than 22% of the servers in the directory. Last change 4 months ago. Version published in the registry: 0.1.0-alpha.24 (July 9, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
