Peptlas MCP server

Ask Claude, ChatGPT, Cursor or any MCP client whether a peptide is legal, and it answers from Peptlas: the status in the U.S., Australia, the UK, the EU, Canada, Brazil and sport, with the primary source and the date. Free, read-only, no account.

The address

https://peptlas.com/mcp
  • Claude (claude.ai and the desktop app): Settings, then Connectors, then Add custom connector. Name it Peptlas and paste the address above. No sign-in is needed.
  • ChatGPT: Add a custom connector in developer mode with the address above and no authentication.
  • Any other MCP client: Point it at the address above. It speaks Streamable HTTP, needs no key and keeps no session.
  • Claude Code:
    claude mcp add --transport http peptlas https://peptlas.com/mcp
  • Cursor (.cursor/mcp.json):
    {
  "mcpServers": {
    "peptlas": {
      "url": "https://peptlas.com/mcp"
    }
  }
}
  • VS Code (.vscode/mcp.json):
    {

    "peptlas": {

Then ask

  • Is BPC-157 legal in Australia?
  • Can a U.S. pharmacy still compound semaglutide?
  • Which peptides does WADA ban?
  • What changed with retatrutide this month?
  • Is TB-500 legal in the UK?

Where the answers come from

The same data as every page on this site, rebuilt with each update. The watchers check the official sources every six hours, and no status changes until a person has checked the primary source (how we track). Every answer names its page, its sources and the date it was last verified.

The data is CC BY 4.0: quote it freely and credit Peptlas. It describes the law, not safety, efficacy or dosing, and it is not legal or medical advice (disclaimer). Peptlas recommends no products or sellers. No account and no cookies: your questions are neither stored nor logged by Peptlas. The full dataset behind the tools is one file,atlas.json.
