PepEvolution Peptide Sources is a remote MCP server that gives an AI agent 3 tools, among them check_vendor, find_peptide_sources, list_verified_vendors. It answers at https://pepevolution.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Find where to buy peptides from vetted, COA-tested vendors and check if a peptide vendor is legit.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_vendor | Check if a research-peptide vendor is legit, a scam, or safe to buy from. Given a vendor name or slug (fuzzy, case-insensitive), returns PepEvolution's independent audit: PepScore grade + band, lab-verified COA status, a short audit summary Inputs: name |
find_peptide_sources | Find where to buy a peptide online from vetted, third-party-tested vendors. Given a peptide or compound name (e.g. BPC-157, tirzepatide, semaglutide, retatrutide, TB-500), returns independently graded vendors ranked by lab-verified Certific Inputs: compound |
list_verified_vendors | List every PepEvolution-graded research-peptide vendor, sorted by PepScore (desc). Each entry carries grade + band, lab-verified COA status, a disclosed buy link (tracked when affiliate), any coupon, and the affiliate disclosure. Use to com |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://pepevolution.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
