What your AI can do with Peptul
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “get_compound_prices”: Live research peptide prices for one compound across every vendor Peptul tracks, normalised to USD per milligram and collected nightly from.”
“Use “get_vendor”: One research peptide vendor's public trust record on Peptul: Peptul Score (0-100 transparency score), third-party testing claim vs Peptul-ve.”
“Use “get_price_history”: How one research peptide's price has moved over time: the cheapest in-stock price per mg on each day, recorded nightly across every vendor P.”
“Use “calculate_reconstitution”: Work out how far to draw on an insulin syringe for a given peptide dose: takes the vial amount, the bacteriostatic water added and the dose.”
How secure is the Peptul MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Peptul holds up.
Security grade A
gate scanned 5 tools on Oct 8, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by Peptul (peptul.com) 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 Peptul adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

Who runs the Peptul MCP server?
The Peptul MCP server at a glance
https://www.peptul.com/api/mcpQuestions, answered
Is there an official Peptul MCP server?
Yes — Peptul operates its own remote MCP server at www.peptul.com. 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 Peptul to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Peptul in the directory. No account or sign-in is needed. From then on, Peptul's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Peptul runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Peptul 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 Peptul in minutes. No credit card required.
