PageMap MCP Server

<!-- mcp-name: io.github.Retio-ai/pagemap -->

PageMap

PageMap converts raw HTML (100K+ tokens) into structured, AI-readable page maps (2-5K tokens) — a 97% token reduction. It works as an MCP server, Python SDK, and CLI, supporting 16 page types and 30+ e-commerce sites. Agents can read, click, type, and navigate any web page.

"Give your agent eyes and hands on the web."

Why PageMap?

Playwright MCP dumps 50-540KB accessibility snapshots per page, overflowing context windows after 2-3 navigations. Firecrawl and Jina convert HTML to markdown — read-only, no interaction.

PageMap gives your agent a compressed, actionable view of any web page:

	PageMap	Playwright MCP	Firecrawl	Jina Reader
Tokens / page	2-5K	6-50K	10-50K	10-50K
Interaction	click / type / select / hover	Raw tree parsing	Read-only	Read-only
Multi-page sessions	Unlimited	Breaks at 2-3 pages	N/A	N/A
Task success (94 tasks)	84.7%	61.5%	64.5%	57.8%
Avg tokens / task	2,710	13,737	13,888	11,424
Cost / 94 tasks	$1.06	$4.09	$3.98	$2.26

Benchmarked across 11 e-commerce sites, 94 static tasks, 7 conditions. 8,100+ tests passing.

Features

13 MCP Tools — Read + Interact

Not just reading — your agent can click buttons, fill forms, select options, manage tabs, and navigate across pages. 13 tools cover the full browsing workflow:

get_page_map · execute_action · fill_form · scroll_page · wait_for · take_screenshot · get_page_state · navigate_back · batch_get_page_map · open_tab · switch_tab · list_tabs · close_tab

16 Page Types, Auto-Detected

PageMap automatically classifies pages and applies optimized extraction for each type:

product_detail · listing · search_results · article · news · video · login · form · checkout · dashboard · help_faq · settings · error · documentation · landing · blocked

E-Commerce Deep Coverage

Built-in support for 30+ major e-commerce sites across 4 tiers:

• Global mega-platforms — Amazon, eBay, AliExpress, SHEIN, Walmart, Rakuten
• Global fashion — Zara, H&M, Nike, Uniqlo, ASOS, Zalando, SSENSE, Farfetch, COS
• Korea — Coupang, Naver Shopping, Musinsa, 29CM, W Concept, SSG, 11st
• Japan/China — ZOZO, Tmall, JD.com, Taobao

Structured extraction of prices, options (size/color), ratings, availability — with automatic cookie consent handling and login barrier detection.

Smart Recovery

PageMap detects problems and tells your agent what to do:

• Barrier detection — Login required? Bot blocked? Out of stock? Age verification? Popup overlay? PageMap adds a barrier field with the diagnosis and suggested next steps
• Cookie consent auto-dismiss — 7 CMP providers auto-detected (Cookiebot, OneTrust, TrustArc, Didomi, Quantcast, Usercentrics, generic fallback). 5-tier dismiss cascade: CMP JS API → Reject → Accept → Dismiss → Close symbol. GDPR reject-first default policy
• Popup overlay detection — AX tree role="dialog" + HTML regex 2-phase detection. Promotional popups (newsletter, exit-intent) auto-dismissed
• Bot detection awareness — Detects Cloudflare, Turnstile, reCAPTCHA, hCaptcha, and Akamai. Reports the provider and suggests wait/retry strategies
• Stale ref recovery — When DOM changes invalidate refs, PageMap returns clear guidance to re-fetch

Content Intelligence

• 8 JSON-LD schemas — Product, NewsArticle, VideoObject, FAQPage, Event, LocalBusiness, BreadcrumbList, and ItemList
• Metadata extraction — Prices, ratings, reviews, descriptions, images from structured data and DOM fallbacks
• 2-layer caching — Cache hit (~10ms), content refresh (~500ms), full rebuild (~1.5s). Diff-based updates for unchanged sections
• Delta evidence packet output - Optional to_delta_packet() serializer emits digest-bound evidence units, claim candidates, provenance, and authority flags for downstream memory/review systems without changing the default MCP output

10 Languages

Locale auto-detected from URL. Token budgets adjusted for CJK scripts.

Language	Locale	Language	Locale
English	en	Chinese	zh
Korean	ko	Spanish	es
Japanese	ja	Italian	it
French	fr	Portuguese	pt

Local (STDIO)

Default mode. Runs as a local MCP server — no server setup needed.

retio-pagemap

Docker

docker run -p 8000:8000 retio1001/pagemap --transport http

Multi-architecture images (amd64/arm64) available on Docker Hub and GitHub Container Registry.

Python API

import asyncio
from pagemap.browser_session import BrowserSession
from pagemap.delta_serializer import to_delta_packet
from pagemap.page_map_builder import build_page_map_live
from pagemap.serializer import to_agent_prompt, to_json

async def main():
    async with BrowserSession() as session:
        page_map = await build_page_map_live(session, "https://example.com/product/123")
        print(to_agent_prompt(page_map))   # Agent-optimized text format
        print(to_json(page_map))           # Structured JSON
        print(to_delta_packet(page_map))   # Digest-bound evidence packet
        print(page_map.page_type)          # "product_detail"
        print(page_map.interactables)      # [Interactable(ref=1, role="button", ...)]
        print(page_map.metadata)           # {"name": "...", "price": "..."}

asyncio.run(main())

For offline processing (no browser):

from pagemap.page_map_builder import build_page_map_offline

page_map = build_page_map_offline(open("page.html").read(), url="https://example.com/product/123")

Security

PageMap treats all web content as untrusted input:

• SSRF defense — Multi-layer protection against server-side request forgery
• Prompt injection defense — Content boundaries, role-prefix stripping, suspicious content flagging
• robots.txt compliance — RFC 9309 compliant. --ignore-robots opt-out flag
• Resource guards — DOM node limit, HTML size limit, response size limit
• Session isolation — Each session has independent cookies and storage, automatically cleaned up

Local development: Private IPs are blocked by default. Use --allow-local or PAGEMAP_ALLOW_LOCAL=1.

Disclaimer

Users are responsible for complying with the terms of service of target websites and all applicable laws when using PageMap.

---

Troubleshooting

"spawn uvx ENOENT" (Claude Desktop on macOS) — Claude Desktop does not inherit your shell PATH. Run which uvx and use the absolute path in your config.

First page takes a long time — Chromium cold start takes ~10-30s on first navigation. Subsequent pages load in 1-3 seconds.

Localhost blocked — Use --allow-local flag or set PAGEMAP_ALLOW_LOCAL=1.

Chromium not found — Run pip install retio-pagemap && playwright install chromium to install manually.

For Agents

This section is written for AI agents using PageMap as an MCP tool.

Tools

Tool	When to use
get_page_map	Start here. Navigate to a URL and get a full structured map with numbered refs.
execute_action	Click, type, select, or hover using a ref number from the last get_page_map.
fill_form	Fill multiple form fields in one call. More efficient than sequential execute_action calls.
get_page_state	Check current URL and title without a full rebuild. Use after actions that may navigate.
scroll_page	Scroll to reveal lazy-loaded content before calling get_page_map again.
wait_for	Wait for dynamic content to appear (e.g. after a search or form submit).
take_screenshot	Capture the visual state when the PageMap alone is ambiguous.
navigate_back	Go back one step in browser history.
open_tab	Open a new browser tab and navigate to a URL.
switch_tab	Switch to a different open tab by index.
list_tabs	List all open tabs with their URLs and titles.
close_tab	Close a tab by index.
batch_get_page_map	Fetch multiple URLs in parallel. Use for comparison tasks.

Output Format

URL: https://example.com/product/123
Title: Product Name
Type: product_detail          # auto-detected page type

[3] link: See all reviews (click)
...

## Info
Price: $49.99
Rating: 4.5 / 5 (128 reviews)
Description: ...

## Images
  [1] https://cdn.example.com/product.jpg

## Meta
Tokens: ~1,800 | Interactables: 24 | Generation: 380ms

• ## Actions — Every interactive element on the page with a stable ref number.
• ## Info — Key page content extracted from HTML: prices, titles, ratings, descriptions.
• ## Images — Product/content image URLs.
• ## Meta — Token count, interactable count, generation time.

Barrier Detection

When PageMap encounters a page-level obstacle, it includes a barrier field in the response:

State:
  barrier: login_required
  barrier_hint: "Login form detected with email + password fields. Use fill_form to authenticate."

Possible barriers: cookie_consent, login_required, bot_blocked, out_of_stock, empty_results, error_page, age_verification, region_restricted, popup_overlay.

When you see a barrier: follow the barrier_hint guidance. For bot_blocked, wait and retry. For login_required, use fill_form with credentials.

Ref Lifecycle

Refs are assigned by get_page_map and remain valid until the page state changes.

Refs are invalidated when:

• The page navigates to a new URL
• A DOM mutation occurs (modal opens, SPA navigation, accordion toggles)
• execute_action causes a page-level change

When you get a stale ref error: call get_page_map again to get fresh refs before retrying.

Token Budget Behavior

When a page exceeds the token budget, content is pruned in this order:

1. Navigation menus, footers, sidebars removed first
2. Secondary body content trimmed
3. ## Actions and ## Info are always preserved

If key content seems missing, try scroll_page to load lazy content, then get_page_map again.

Recommended Workflow

1. get_page_map(url)          → read Actions + Info, pick refs
2. execute_action(ref, ...)   → interact
3. get_page_state()           → confirm navigation occurred
4. get_page_map(new_url)      → get fresh refs for next step

For pages with dynamic content (search results, filters):

1. get_page_map(url)
2. execute_action(ref, "click")    → trigger search/filter
3. wait_for(text="results")        → wait for content
4. get_page_map(url)               → get updated map

Known Limitations

• Login-gated pages — PageMap does not manage sessions or cookies. Authentication must be handled externally.
• Heavy bot detection (Cloudflare, Akamai) — May block automated access. PageMap detects the provider and suggests strategies, but cannot bypass active bot mitigation.
• Private network access — Blocked by default. Requires --allow-local flag.
• iframes — Cross-origin iframes are not accessible due to browser security policies.
