LABSCO SUMMARY

The markdown return format is the quiet win.

Impersonation is the headline, and it is what gets you past clients that reject non-browser fingerprints. But the option that changes daily use is return_format: asking for markdown means a fetched page arrives as something a model can read, rather than several thousand tokens of tags. Pick the impersonation profile deliberately — the version list is long and specific for a reason.

What it is

A Python server around the primp HTTP client, whose distinguishing feature is browser impersonation: the request carries the TLS and header fingerprint of a specific browser version rather than a generic client. Two tools cover the ground — one for ordinary requests, one for multipart file uploads.

What you get

  • primp_request performs GET, POST, PUT, PATCH, DELETE, HEAD or OPTIONS with an impersonate profile and an impersonate_os
  • primp_upload posts files as multipart form data, taking base64 content with a filename and content type
  • return_format shapes the response as text, JSON, markdown, plain text or rich text — so a page can come back readable instead of as raw HTML
  • Impersonation profiles cover Chrome 99-131, Firefox 99-133, Safari 12-18 including iPad and iPhone, Edge 99-131 and OkHttp 3.14.9-5.0.0
  • Operating systems: Windows, macOS, Linux, Android, iOS
  • Basic auth and Bearer tokens, HTTP/HTTPS proxies, configurable timeouts, redirect handling and SSL verification

Requirements

No account and no key. Install from a checkout with pip install -e ., then set the command to primp-mcp in your client config. Project primp-mcp, version 0.1.0. It will fetch any URL you give it with your network access, so treat it the way you would treat curl on the same machine.

Setup effort

One command — primp-mcp
