DrissionPage MCP Server

Professional browser automation for Codex, Claude Code, and MCP clients, powered by DrissionPage.

DrissionPage is a Python web automation library built around direct Chromium/CDP control with requests-style HTTP session support. This server exposes its browser-facing capabilities as typed, atomic MCP tools.

Open the interactive Browser Lab to replay bounded natural pointer motion, drag controls, and verify observable state.

🖱️ Atomic Browser Control with Natural Pointer Motion

DrissionPage MCP 0.8.0 exposes 69 typed browser capabilities. The MCP server provides accurate low-level observation and interaction; the client or an optional Skill composes those capabilities for a site, component library, or business workflow.

The model decides what to do; the MCP executes the requested browser operation exactly.

Core interaction guarantees

• Two bounded profiles: direct emits one exact move; natural emits a deterministic 24-step eased cubic path with reproducible 8-14ms intervals and exact final arrival.

• No hidden randomness: the same start, target, and profile produce the same path; there is no jitter, overshoot, or anti-detection logic. Pointer position is stateful, so a repeated call can begin from the previous endpoint.

• Explicit sequences: click is the selected move profile, optional caller-specified delay, press, release; drag keeps one press across the selected path and ordered waypoints.

• Failure-safe input: a pressed pointer button is released if execution fails after the press.

• Fresh browser evidence: selector geometry is resolved immediately before selector-backed drag operations.

• Typed results: outputs report the executed coordinates, button, step count, and explicit delay metadata.

Use structured DOM targets when reliable selectors exist. Use coordinates, natural motion, and explicit drag waypoints for canvas controls, editors, maps, charts, and other visual-only surfaces. Component-specific target discovery, challenge observation, multi-click sequencing, login procedures, and other business policy belong in the client or an optional Skill.

Designed for authorized browser automation, testing, accessibility workflows, and technical research. The core does not provide challenge-specific or site-specific workflows.

🚀 What is DrissionPage MCP?

DrissionPage MCP Server is a local Model Context Protocol (MCP) server that brings DrissionPage browser automation tools to Codex CLI/IDE, Claude Code, Claude Desktop, and other MCP clients.

The standalone server exposes 69 typed tools, zero MCP prompts, and one static optional-Skills catalog resource. Version 0.8.0 stabilizes that registry with opt-in Web Storage values, redacted keyboard results, selector/coordinate/keyboard download correlation, fail-closed timeout cleanup, and clearer browser-start/runtime errors. Every tool loads by default; there is no capability profile or opt-in full mode. Models compose these atomic capabilities, while reusable procedures live outside the distribution as optional Skills. Browser execution is powered by DrissionPage.

🌟 Why Choose DrissionPage MCP?

• Structured-First, Vision-Ready: Uses DOM structure when available and multimodal coordinates when visual interaction is the better tool

• Deterministic: Reliable element selection with CSS/XPath normalization for LLM-friendly selectors

• Natural Pointer Motion: Offers exact direct movement and a bounded deterministic 24-step eased trajectory from the same atomic tools

• Fast & Lightweight: Built on DrissionPage's efficient engine with minimal overhead

• Type-Safe: Full type hints and Pydantic validation for all tools

• Open-source Friendly: Includes compatibility notes, troubleshooting, and CI checks for maintainable contributions

• Easy Integration: Simple pip install + Codex TOML or MCP JSON configuration

✅ Quality and Real-World Validation

DrissionPage MCP is backed by a strict regression suite and browser-backed scenario checks:

• Strict automated tests: unit, protocol, schema snapshot, response-contract, resource, release-metadata, security-policy, browser-integration, and coverage checks run in CI.

• 95% coverage floor: CI enforces the current 95% coverage threshold and uploads coverage reports.

• Real browser verification: Chrome/Chromium-backed integration tests exercise the same MCP tools exposed to clients.

• Document-boundary verification: focused browser tests prove cross-origin OOPIF reads and DrissionPage-exposed closed Shadow DOM lookup without JavaScript piercing fallbacks.

• Scenario validation: the playground MCP Lab covers realistic forms, commerce pages, social feeds, timelines, dynamic waits, iframe cases, and recovery paths without depending on public demo websites.

⚡ First Success Path

# Install from PyPI
python -m pip install -U "drissionpage-mcp>=0.8.0"

# Verify package and environment
drissionpage-mcp --version
drissionpage-mcp doctor

Then add the Codex or MCP client configuration below and restart your client.

📦 Setup in Codex CLI/IDE (30 seconds)

Codex supports local stdio MCP servers through config.toml; the CLI and IDE extension share the same MCP configuration.

1. Edit Codex configuration:

   • User-level: ~/.codex/config.toml

   • Project-level: .codex/config.toml inside a trusted project

2. Add this configuration:

   [mcp_servers.drissionpage]
   command = "drissionpage-mcp"
   startup_timeout_sec = 20
   tool_timeout_sec = 60

3. Restart Codex. In the TUI, run /mcp; from a shell, run codex mcp list.

🐛 Troubleshooting

Tools Not Loading?

drissionpage-mcp --version

Should output the installed package version, for example drissionpage-mcp 0.8.0.

drissionpage-mcp doctor must also report both mcp_supported and mcp_server_wiring as ok; package-version output alone does not prove that an MCP client can initialize the server.

Browser Issues?

# Check browser installation
which google-chrome    # Linux
which chromium         # macOS

Codex / MCP Client Not Finding Server?

• Codex: run codex mcp list; in the TUI, run /mcp

• JSON clients: verify config file path and JSON syntax

• Restart Codex or your MCP client after changes

• Check logs: drissionpage-mcp --log-level DEBUG

See docs/troubleshooting.md for the complete troubleshooting guide.

🗺️ Roadmap

Current (v0.8.0)

• 69 atomic navigation, tab/frame/shadow, accessibility, observation, interaction, browser-environment, network, Cookie/storage, wait, and console tools, all loaded by default

• stdio MCP server integration

• Doctor diagnostics for local setup

• Stable JSON mirror, structuredContent, and typed per-tool MCP outputSchema

• Structured recovery hints in error.details.hints for common failures

• Sanitized browser failures with DIALOG_PENDING/DIALOG_NOT_FOUND recovery and strict standards-compliant JSON for non-finite JavaScript values

• Balanced page_snapshot output so link-heavy pages still expose controls and forms

• Atomic type, select, check, click, keyboard, upload, wait, and state-read tools cover native controls and framework-driven widgets without library-specific branches

• Tab management with tab_list, tab_switch, tab_close, and page_navigate(new_tab=true)

• Observable actions with page_observe, page_evaluate, wait_until, and optional observe=true changes on navigation, click, and type

• Console observability with page_console_logs, console summary in page_observe, and console change fields in observe=true

• Form, component-library, challenge, and convenience workflows remain outside the MCP core

• Optional Skills are discoverable through one static resource and excluded from wheel and sdist packages

• Capability-probed page_dialog_respond, additive double/context click behavior, and selector/coordinate/keyboard download correlation with safe ArtifactRef metadata

• Secret-bearing Web Storage values require include_values=true; keyboard and keyboard-download results expose redacted metadata only

• Per-tab download trigger locking, shared deadlines, cleanup/replay guarantees, and a 250ms fail-closed late-mission guard

• Reproducible W01-W08 public-tool benchmark with ten isolated runs per workload, machine-readable evidence, and zero duplicate side effects

• Network listener beta with network_listen_start, network_listen_wait, and network_listen_stop for HTTP/XHR/Fetch observation

• Browser-only request environment control with echoed header, user-agent, and blocked-URL writes plus cache-only clearing that preserves Cookies and Web Storage

• direct and deterministic bounded natural profiles for page_pointer_move, page_pointer_drag, and page_click_xy, with exact endpoints and failure-safe release

• Optional bounded page_pointer_drag.waypoints for one held multi-segment canvas, map, box-selection, or visual-editor gesture

• File upload, scrolling, hover, select/check, keyboard, iframe, shadow DOM, cookie, and storage tools for DrissionPage 4.x

• Pure browser Cookie set/get/delete/clear flow, including bounded batch writes whose successful results echo values for MCP callbacks

• Ten-cycle controlled and validation input replacement through native DrissionPage input on the supported browser matrix

• Cross-origin OOPIF reads through frame_* and closed Shadow DOM lookup through DrissionPage-backed shadow_*, with narrower pointer targeting documented separately

• Backward-compatible string or structured selector/accessibility targets across element reads, actions, waits, uploads, and click-download correlation, resolving ordered frames first and then ordered Shadow DOM hosts

• Bounded accessibility snapshots, non-handling native dialog observation, and live element state/geometry for autonomous locate-act-verify loops

• Browser permission observation/set/reset, managed PDF/MHTML artifacts, automatic file chooser interception, and credential-redacted HTTP auth isolated by disposable Chromium context

• Chrome sandbox remains enabled by default; DP_NO_SANDBOX=1 is reserved for restricted container/root environments

• No retained action history, generated code snippets, or absolute screenshot paths in public results

• Opt-in local safety policy for navigation and screenshot paths

• One optional-Skills catalog resource, zero prompts, plus eval, compatibility, and troubleshooting documentation

• PyPI distribution

🆕 Latest Version: v0.8.0

Released on 2026-07-31. This release stabilizes the 69-tool contract without adding public tool names or bundling Skills, component adapters, or business workflows:

• Makes localStorage/sessionStorage values opt-in through include_values=true, and returns redacted metadata from keyboard_press and keyboard-triggered downloads.

• Extends element_click_and_download with strict coordinate and keyboard triggers while preserving selector/accessibility calls, operation-key replay, and one-trigger/one-mission correlation.

• Serializes generic download triggers per tab under one shared deadline, restores prior state on all terminal paths, and cancels late missions during a 250ms fail-closed guard.

• Classifies browser-start and dialog failures before generic runtime fallback while redacting localized DrissionPage, CDP, private destination, and rejected-path details.

• Enforces Ruff and mypy in GitHub CI, then runs multi-version unit/protocol tests, browser boundaries, full browser coverage, W01-W08, clean-wheel stdio, and package privacy gates.

• Keeps advanced held-key, IME/composition, touch/pinch, and clipboard capabilities deferred until their lifetime, cleanup, policy, and browser support can be verified.
