Web Agent Protocol
A standardized framework for recording browser user interactions via a Chrome extension and replaying them either exactly or as AI-condensed smart sequences, with the ability to convert recordings into reusable MCP servers for AI agent consumption.

⚙ Agent Friendliness
🔒 Security
Community/specialized tool. Apply standard security practices for category. Review documentation for specific security requirements.
⚡ Reliability
Best When
You have a stable, repeatable browser workflow you want to encode once and expose to AI agents as an MCP tool, especially for sites without APIs.
Avoid When
The target website changes its DOM structure frequently, or you need to handle branching logic and dynamic content — use Browser-Use or Playwright directly instead.
Use Cases
- • Recording repetitive browser workflows once and replaying them via AI agents
- • Generating MCP servers from recorded browser sessions for reuse across teams
- • Automating web tasks that require navigating sites without public APIs
- • Building RPA-style automation that AI agents can invoke through a standard protocol
Not For
- • Sites with heavy anti-bot measures or dynamic DOM structures that change between sessions
- • Users who need zero-code setup — Python 3.11 + Conda + API keys required
- • Real-time or event-driven automation (record-replay model is batch-oriented)
Interface
Authentication
Requires OpenAI API key and/or DeepSeek API key for smart replay generation. Chrome extension for recording has no auth.
Pricing
MIT licensed. LLM costs apply for smart replay; exact replay is purely local.
Agent Metadata
Known Gotchas
- ⚠ Recordings require explicit task-start and task-finish Chrome extension events to be valid
- ⚠ Replay accuracy breaks when DOM structure changes between recording and playback
- ⚠ Python 3.11 + Conda environment required — no pip-only install path
- ⚠ Collection server must be running on localhost:4934 during recording sessions
