Anlyon alternative

8 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Description, as the server wrote it
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.

Why it is in this group

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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.

Description, as the server wrote it
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.

Description, as the server wrote it
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.

Description, as the server wrote it
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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as lab-tools. Review it before you use it.

Keep the decision: fail CI when the tools change, follow every change, or show a badge.

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
