Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 613 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name verbex-lab-tools.

  • Pass
    Lists tools

    tools/list returned 10 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 613 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 613 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    58 of 74 parameters have a description (78%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-11-07T18:04:44.103987Z, within 180 days.

  • Not measured
    Open-source licence

    No GitHub repository to ask about a licence.

Capabilities

Tools 10

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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.
