Verbex Lab Tools: deterministic wet-lab calculators and lab document templates, each checked.

Overview

AI-generated overview

Remote MCP server giving assistants deterministic wet-lab calculators and lab document templates, plus searchable Verbex guides.

What you can do
  • Compute bench calculations: solution prep, serial dilutions, PCR/qPCR master mixes, LNP formulations and multiwell plate layouts
  • Search and read Verbex guides and the 16 lab documentation templates, with citable URLs
  • Build structured lab protocols and electronic lab notebook entry templates as Markdown and HTML
  • Parse reagent bottle or kit label text into structured fields such as catalog number, lot, expiry and storage
When to use it
Useful when an assistant helps with wet-lab work and must return exact masses, volumes, concentrations or dilution series instead of estimating them, or when someone needs ready-made protocol, ELN or plate-layout documents.
Requirements
Remote streamable HTTP endpoint at the provider's site; no account, API key, environment variable or header is declared. Inputs are sent to the server for computation only.
Before you install
Results are calculation aids with a self-check, not validated or verified values; the scientist must confirm them against lab requirements. Tool warnings and safety notes should be shown to the user. Reagent label text is sent to the server, so avoid pasting unrelated confidential content.

Installation

In SourceWeft

  1. Open Verbex Lab Tools in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.verbalexperiment%2Flab-tools/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Tools

fetch

Read a Verbex guide, template or tool

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.

Parametersidrequired

solution_prep

Solution prep (molarity and C1V1)

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.

serial_dilution

Serial dilution planner

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.

pcr_master_mix

PCR / qPCR 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.

lnp_formulation

LNP formulation (lipid nanoparticles)

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.

plate_map

Plate map (6- to 384-well)

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_template

Lab 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.

eln_template

Electronic lab notebook entry 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.

parse_reagent_label

Reagent label parser

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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
