Nothing serious here today
Today is the operative word: we check Verbex Lab Tools every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
eln
eln_template
Build an electronic lab notebook (ELN) entry template for an experiment: objective, materials, procedure, observations and conclusion sections from a preset or custom list, optionally with timestamp fields and voice-capture prompts. Returns Markdown and HTML.
fetch
fetch
Get the full text of a search result by id, as Markdown. Guides come with a short summary; templates include the blank template, a worked example where there is one, and a link to the editable Word or Excel file. Calculators return the method, the input fields and a worked example computed by the calculator.
lnp
lnp_formulation
Plan a lipid nanoparticle (LNP) formulation for RNA: from RNA mass, N/P ratio and lipid mol% (e.g. ionizable lipid/DSPC/cholesterol/PEG-lipid 50/10/38.5/1.5), calculate moles, mass and stock volume of every lipid, the ethanol and aqueous phase volumes at the chosen mixing ratio (default 3:1), and final RNA concentration, ethanol fraction and lipid:RNA ratio. Molecular weights must come from the user or certificates of analysis.
parse
parse_reagent_label
Turn text read from a reagent bottle or kit label (OCR or typed) into structured fields such as product name, catalog number, lot, expiry, concentration and storage. Parses the provided text only; send the label text, not an image.
pcr
pcr_master_mix
Use when someone sets up a PCR or qPCR reaction mix for several wells. Calculates volume of each component per reaction and for the whole mix with excess, with water filling the remaining volume. Give each component a stock and final concentration (molar, ng/µL, x buffer, %), an amount per reaction (e.g. 1.25 U polymerase from 5 U/µL, 10 ng template from ng/µL), or a fixed volume. Template can be added per well separately. Do not list water; it is calculated.
plate
plate_map
Use when someone lays out a multiwell plate (ELISA, qPCR, cell or compound assays). Lays out a 6, 12, 24, 48, 96 or 384-well plate: standards, samples, controls and blanks with replicates, filled by row or column, optionally leaving edge wells empty and keeping replicate sets together. Returns a grid with a key and a well-by-well list.
protocol
protocol_template
Build a structured lab protocol (purpose, materials, procedure, critical steps, acceptance criteria and more) for a protocol title, using a preset or custom sections. Returns Markdown and HTML ready to fill in or print.
search
search
Search Verbex guides and templates: practical guides (protocols and SOPs, lab notebooks, inventory, data integrity and GLP, equipment records, bench calculations) and the 16 lab documentation templates. Returns ids to pass to fetch, with titles and urls to cite. Not for calculations: to compute a mass, volume, dilution, master mix, LNP formulation or plate map, call that calculator directly.
serial
serial_dilution
Use for any serial dilution (standard curves, titrations, dose series). Plans transfer and diluent volume per tube and the resulting concentration at each step, from a stock concentration, a constant dilution factor, the number of tubes and the final volume per tube.
solution
solution_prep
Use when someone asks how much solid to weigh for a molar solution (how many grams for X mM in Y mL, making up a buffer or salt solution), or how much stock to dilute to a target concentration (C1V1). mode "solid": mass of solid to weigh from molecular weight, target concentration and final volume. mode "stock": C1V1 = C2V2 dilution from a stock, solving for stockVolume, stockConcentration, targetConcentration or finalVolume. Returns the primary result, a step summary, warnings and safety notes.

Verbex Lab Tools — questions
Answers built from our own checks of this server.
What can Verbex Lab Tools do?
It exposes 10 tools, read directly from the server on our last check. Among them: eln_template, fetch, lnp_formulation, parse_reagent_label, pcr_master_mix, plate_map and 4 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 Verbex Lab Tools working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 13 of 13 checks got a reply (100.0%), average response time 1023 ms. The bar chart above shows every period we have measured.
How do I connect Verbex Lab Tools?
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 Verbex Lab Tools need an API key?
No. Verbex Lab Tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Verbex Lab Tools?
It answers our handshake in 1023 ms on average, which is faster than 4% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
