Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

peptide

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 Certificate of Analysis (COA) quality, with PepScore purity grades, coupon codes, and disclosed referral purchase links. Use for "where can I buy X", "best source for X", "which peptide vendor is trusted for X". Fuzzy, case-insensitive matching.

vendor

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 of red/green flags, a disclosed buy link (tracked when affiliate) and any coupon, or a clear "not evaluated" result. Use for "is [vendor] legit", "[vendor] review", "[vendor] scam".

verified

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 compare trusted peptide vendors at a glance.

PepEvolution Peptide Sources — questions

Answers built from our own checks of this server.

What can PepEvolution Peptide Sources do?

It exposes 3 tools, read directly from the server on our last check. Among them: check_vendor, find_peptide_sources, list_verified_vendors. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is PepEvolution Peptide Sources working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 141 ms. The bar chart above shows every period we have measured.

How do I connect PepEvolution Peptide Sources?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does PepEvolution Peptide Sources need an API key?

No. PepEvolution Peptide Sources completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is PepEvolution Peptide Sources?

It answers our handshake in 141 ms on average, which is faster than 79% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
