cdpilot
cdpilot is a CLI for local browser automation using Chrome DevTools Protocol (CDP), offering many browser-control commands (navigation, clicking, typing, screenshots/PDF, console/network/diagnostics, network throttling/proxy, request interception, device emulation, geolocation, cookies/storage, tabs, etc.). It also advertises an MCP server/tool mode so AI agents can invoke the CLI. It launches an isolated browser profile/session locally and communicates with the browser over local CDP endpoints (127.0.0.1 by default).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Strengths (from README): isolated browser profile (~/.cdpilot/profile), CDP listens on 127.0.0.1 by default (no remote connections by default), warnings about safer selector handling (JSON-escaped selectors), claims of path traversal protection for screenshot filenames, and local-only execution/privacy-first. Gaps/unknowns: no explicit secrets management guidance beyond local profile; no authentication/authorization model because it’s local CLI; dependency list is empty in the provided manifest but the underlying implementation details/dependency scan are not verifiable from the provided data; TLS is relevant only if any local HTTP/WebSocket is exposed, which is not clearly documented—score reflects that remote exposure is discouraged but not fully specified.
⚡ Reliability
Best When
You want a lightweight, local, CLI-first CDP automation tool (optionally callable as an MCP tool) for agent-driven browsing, screenshots/PDFs, and debugging with minimal dependencies.
Avoid When
You need a formally specified HTTP/SDK API with strong error codes, explicit rate-limit policies, and documented retry/idempotency semantics; or you require enterprise authentication/authorization controls beyond local execution.
Use Cases
- • AI agent/browser tool-use for web navigation and interaction
- • Automated QA/testing of web flows via CDP without heavy browser automation frameworks
- • Debugging and diagnostics (console/network/perf/screenshots) for web pages
- • Web scraping workflows that require deterministic DOM interactions (non-credentialed/local use)
- • Generating artifacts (screenshots, PDFs) and capturing page content/HTML/text
- • Network simulation (throttle/offline/proxy) and request interception for testing
- • Accessibility tree inspection and element discovery by ARIA role
Not For
- • Running remote/hosted untrusted browser automation where localhost CDP exposure cannot be controlled
- • High-complexity, multi-browser test runners requiring first-class SDKs/framework integrations
- • Use cases requiring strong enterprise-grade governance (auditing, RBAC, managed browser infrastructure) before the promised cloud/team features exist
- • Use cases requiring fine-grained, standardized web automation APIs with robust programmatic idempotency and retries documented at the protocol level
Interface
Authentication
No API authentication/authorization mechanism is documented because cdpilot is a local CLI that controls a locally launched browser via CDP (127.0.0.1). Any MCP integration appears to be invoked by the agent via a local command (npx) rather than via a secured remote service.
Pricing
Monetization is described as future/coming soon for cloud/team/priority support, but no pricing or limits are provided for the local CLI.
Agent Metadata
Known Gotchas
- ⚠ Browser/UI automation can be timing-sensitive; README roadmap mentions “Auto-wait” as not yet implemented, which may increase flakiness for agents that click/type immediately after navigation.
- ⚠ Commands are CLI/subprocess-oriented; when used from agents, output parsing and state management (active tab/session/port/profile) may require careful handling by the agent.
- ⚠ Some advanced DOM contexts are not indicated as supported (e.g., roadmap lists iframe & Shadow DOM support as not yet done).
