What your AI can do with Peptide Library
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_peptides”: Search the Peptide Library research database by name, synonym or alias (fuzzy), optionally filtered by research category or research area. R.”
“Use “get_peptide_details”: Full educational research profile for one peptide: classification, mechanism and targets, research areas, evidence by tier (regulatory label.”
“Use “compare_peptides”: Side-by-side research comparison of 2-3 peptides on structured profile fields: mechanism and targets, research areas, evidence level and hum.”
“Use “search_research”: Search Peptide Library's own educational content: the site FAQ, per-peptide FAQs, published articles and free courses. Returns titles, short.”
How secure is the Peptide Library MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Peptide Library holds up.
Official endpoint
Operated by Peptide Library (peptidelibrary.app) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Peptide Library adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Peptide Library
Choose Peptide Library in the gate directory. No sign-in needed.
Use it anywhere
Peptide Library's tools are live in every AI client you've connected — with rules and logging built in.

Who runs the Peptide Library MCP server?
The Peptide Library MCP server at a glance
https://peptidelibrary.app/mcpQuestions, answered
Is there an official Peptide Library MCP server?
Yes — Peptide Library operates its own remote MCP server at peptidelibrary.app. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Peptide Library to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Peptide Library in the directory. No account or sign-in is needed. From then on, Peptide Library's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Peptide Library runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Peptide Library MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Peptide Library in minutes. No credit card required.
