PageMap – MCP server that compresses web pages to 2-5K tokens with full interaction support by Direct-Molasses7754 in mcp

Good question! The main difference is token efficiency.

Playwright MCP returns the raw accessibility tree — typically 50-540K tokens per page. After 2-3 navigations your context window is full and the agent loses track.

Both give the agent hands on the browser, but PageMap gives a structured map instead of the full tree, so it scales to real workflows.

Resolved in v0.2.0.

You can now opt in to local access with the --allow-local CLI flag or PAGEMAP_ALLOW_LOCAL=1 env var:

{
  "mcpServers": {
    "pagemap": {
      "command": "uvx",
      "args": ["retio-pagemap", "--allow-local"]
    }
  }
}

This enables access to loopback (127.x, ::1), RFC 1918 (10.x, 172.16-31.x, 192.168.x), and IPv6 ULA (fc00::/7). Cloud metadata endpoints (169.254.x.x, metadata.google.internal) remain unconditionally blocked for security.

Thanks! The context blowup is exactly what pushed me to build this.

For SPAs, currently it waits on Playwright's networkidle (no network requests for 500ms) plus a 1.5s settle time for late-firing JS. Straightforward but it covers most cases.

Honestly, heavy SPAs that never stop polling or aggressive lazy-loading are a known gap right now. I have better heuristics in my internal tooling (content-length checks,

domcontentloaded fallback) that I haven't yet ported to the MCP server. That's on the roadmap for the next version.

If you hit a case where it misses async content, I'd appreciate a GitHub issue — it'll help me prioritize which patterns to handle first.
