PeptideLab Calculator does not always answer

Over the last week it answered 0.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 6

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

plan

plan_schedule

Generate a week-by-week research schedule: frequency presets (daily / 1-3x weekly), GLP-1 style titration ladders and optional syringe-unit readouts per event. On-demand compounds return an advisory instead of a calendar. Research use only.

plan_stack

Plan a multi-compound stack: per-compound draw volumes and units, combined draw volume with split-injection advisories, and frequency-conflict detection. Research use only.

calc

calc_reconstitution

Calculate peptide reconstitution: concentration, draw volume, syringe units and doses per vial. Forward mode: dose_mcg. Reverse mode: pass dose_units to back-solve the dose. Returns precision (parallax) warnings, syringe overflow checks and concentration advisories. Research use only.

compare

compare_syringes

Compare U-100 and U-40 syringes for one target dose: units required, fit and relative reading error (parallax risk). Sorted best-first. Research use only.

peptides

list_peptides

List or search the curated research peptide dataset (ids, names, aliases, categories, confidence grades, common dosing windows). Research use only.

protocol

get_protocol

Get the full research protocol record for one peptide: dosing window, frequency, cycle, titration ladder (GLP-1 class), special notes and confidence grade. Research use only.

PeptideLab Calculator — questions

Answers built from our own checks of this server.

What can PeptideLab Calculator do?

It exposes 6 tools, read directly from the server on our last check. Among them: calc_reconstitution, compare_syringes, get_protocol, list_peptides, plan_schedule, plan_stack. 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 PeptideLab Calculator working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 460 checks got a reply (0.0%), average response time 804 ms. The bar chart above shows every period we have measured.

The registry lists PeptideLab Calculator 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 PeptideLab Calculator?

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 PeptideLab Calculator need an API key?

No. PeptideLab Calculator completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
