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

build
build_cart
Make a curo.you cart link for products and quantities. Use it only when the user wants to buy. It does not place an order or take payment: the user opens cart_link, then checks out and pays on curo.you. Returns the cart lines and cart_link.
coa
get_coa
Read third-party lab reports (COAs) by lot number or product. Each report gives the lab, lot, test date, identity result, purity, potency, a report link and a link to verify it on the lab's own site. Use it for questions about testing, purity or a lot number. Use get_product for prices and stock.
peptide
peptide_research
Read the PepBank brief for one peptide: names and aliases, an evidence summary split into human, animal and lab studies, key findings with citations, regulatory status, and the PepBank credit line to show with the answer. Use it when the user names one peptide. Use search_research for a question across many studies, such as an outcome or a body system. If PepBank has no data, the result gives a PepBank link.
product
get_product
Read every dose of one Curo product, with price, stock and the lab reports (COAs) for each lot. Call search_products first and pass a slug from its results. Use get_coa when the user gives a lot number.
products
search_products
Find Curo products by peptide or product name, or list all products when query is empty. Returns name, slug, dose, price in USD, stock, a lab report link and a buy link. Use get_product for every dose of one product with its lot reports. Use peptide_research for what the studies say.
research
search_research
Search PepBank study findings across all peptides by topic, outcome or question. Each result gives the finding in plain words, the peptide, the evidence class and its source passages. The response also gives the PepBank credit line to show. Use it for questions like "which peptides were studied for tendon healing". Use peptide_research when the user names one peptide.
store
get_store_info
Read Curo's shipping, returns, contact and research-use-only policies, with a link to each policy page. Use it for questions about delivery, refunds or how to reach Curo. Product facts come from search_products and get_product.

Curo: Peptide Research AI Agent with Prices, Stock and Lab Reports (COAs) — questions

Answers built from our own checks of this server.

What can Curo: Peptide Research AI Agent with Prices, Stock and Lab Reports (COAs) do?
It exposes 7 tools, read directly from the server on our last check. Among them: build_cart, get_coa, get_product, get_store_info, peptide_research, search_products and 1 more. 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 Curo: Peptide Research AI Agent with Prices, Stock and Lab Reports (COAs) working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 109 ms. The bar chart above shows every period we have measured.
The registry lists Curo: Peptide Research AI Agent with Prices, Stock and Lab Reports (COAs) as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Curo: Peptide Research AI Agent with Prices, Stock and Lab Reports (COAs)?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Curo: Peptide Research AI Agent with Prices, Stock and Lab Reports (COAs) need an API key?
No. Curo: Peptide Research AI Agent with Prices, Stock and Lab Reports (COAs) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
