Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 136 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-06-18, serverInfo.name pepevolution.

  • Pass
    Lists tools

    tools/list returned 7 tools.

  • Pass
    Current protocol

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

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 136 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 136 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.

  • Pass
    Parameters documented

    9 of 9 parameters have a description (100%). 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 2026-08-15T23:36:21.725291Z, within 180 days.

Capabilities

Tools 7

calculate_reconstitution

Reconstitution arithmetic: given vial size (mg), bacteriostatic water added (mL), and a dose, returns concentration, dose volume in mL, units on a U-100 insulin syringe, and doses per vial. Pure math; it does not judge whether a dose is appropriate.

Discovered
check_vendor

PepEvolution's independent audit of a research-peptide vendor: PepScore grade + band, COA status, audit summary, and buy link for graded vendors; the COA-audit record (status, risk flags) for vendors audited but not graded; or a clear "not evaluated". Strict matching: generic words like "peptides" or "labs" never match, and ambiguous names return candidates instead of a guess.

Discovered
find_peptide_sources

Vendors that carry a peptide, tiered by PepEvolution COA audit status. `vendors` lists only vendors whose COAs are verified real, batch-matched, and from a named independent lab, ranked by Source Match (vendor grade × batch-COA freshness; ties resolve to the non-affiliate). `unaudited_vendors` publish COAs PepEvolution has not authenticated. Vendors with shared/recycled, fabricated, or no COAs are excluded and only counted. Strict name matching (e.g. BPC-157, TB-500, tirzepatide).

Discovered
get_compound_grade

A peptide's PepScore grade: score, band, category, one-liner, last_graded, and cite_url.

Discovered
get_dosing_guide

Doses used in published research for a peptide, each row with route, caveats, and citations, plus regulatory status, evidence summary, pharmacology, safety notes, and a worked reconstitution example. Educational research context, NOT a dosing recommendation or medical advice. Covers compounds with a /dosing page; others return matched compound with has_dosing_guide:false.

Discovered
get_peptide_price

Research-vendor pricing from the PepEvolution price index: median/p25/p75 $/mg, vendor_count, last_scraped, and cite_url.

Discovered
list_verified_vendors

Every PepEvolution-graded research-peptide vendor, sorted by PepScore desc. On a score tie the non-affiliate ranks first. Each entry carries grade + band, COA status, buy link, coupon, and is_affiliate.
