Anlyon alternative

3 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.

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Math for vials holding two or more peptides (KLOW, GLOW, BPC-157 + TB-500, CJC-1295 + Ipamorelin): units to draw and how much of each peptide one draw delivers. Name a known blend or list the components, then give the dose for one component (targetPeptide) or for the whole blend (totalDose).

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Exact reconstitution math for a single-peptide vial: insulin syringe units for a dose, concentration after adding bacteriostatic water and doses per vial, or the dose held in a given number of units. Flags likely mg/mcg mix-ups against the peptide's published range. Returns a calculator link.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Plans supply and cost: how long a vial lasts, how many vials a cycle needs, and cost per dose, week and cycle when pricePerVial is given. Counts whole doses and respects how long a mixed vial keeps (from the dataset when a peptide is named).

    Why it is in this group

    • The name "peptide_compare" says "compare": a word for reading.
    Description, as the server wrote it
    Side-by-side comparison of two peptides (e.g. semaglutide vs tirzepatide, BPC-157 vs TB-500): evidence, FDA status, half-life, routes, vial sizes, storage, published dose ranges and key differences, each labelled by origin.

    Why it is in this group

    • The name "peptide_lookup" says "lookup": a word for reading.
    Description, as the server wrote it
    For questions about one peptide: published dose ranges and protocols, reconstitution, vial sizes, side effects, storage, half-life, FDA status, stacks and community reports. Each dose row carries an origin label (clinical study, guide, community-reported, regulatory), sources and page links.

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.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json

  "permissions": {
    "allow": [
      "mcp__peptides__peptide_lookup",

}

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 peptides. Review it before you use it.

Pin

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.
