Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 521 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name graviti.

  • Pass
    Lists tools

    tools/list returned 7 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 521 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 521 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 11 parameters have a description (82%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Pass
    Source repo linked

    A 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

category_landscape

Comparison-table view of every brand in a category across disclosed attributes, with verification status marked per entry. Entries with captured ingredient/spec data also carry info_quality (0–100 disclosure completeness — transparency, never a rank factor; absent means not yet assessed, not zero). Every row carries evidence_state (audited / sourced / catalog_only); catalog_only rows are landscape presence only — never ranked or recommended. Rows include site_url and attributed_url (utm_source=graviti + signed gvt token — surface-level referral attribution, no user data); prefer attributed_url when linking. Rows with a published, receipt-backed discount code carry an offers array — disclosure only, never a ranking input.

Discovered
get_accountability_log

Public, machine-readable log of every seal lifecycle change: flags, degradations, revocations, and restorations, with dates and reasons — plus confirmation-loop events (event: confirmation_request / confirmation_resolved), where the audit asked a brand to confirm a claim it couldn't re-verify: a visible ask, never a penalty. Also logged: claim_removed (a claim struck from a record, reason public), gap_report_delivered (a paid-tier report delivered to a brand, payment status disclosed — findings and rank never affected), and roster events (brand_added with lane/source, brand_removed, brand_declined, brand_skipped — every future change to who is in the index lands here per brand, reason public). The seal can be lost — a pulled seal is the loudest proof it means something. Payment can fast-track a re-evaluation; it can never change what it finds.

Discovered
get_gap_report

What stands between a brand and top-of-category: attribute gaps vs the category leader, open flags, cohort blind spots per buyer-intent voice, and the ingredient/spec disclosure dimension — the brand's info_quality score with the exact publishable fixes that would raise it (publishing more truth, not paying Graviti). Demo of the paid brand-intelligence product — computed deterministically from the index; in production also draws on consented, compensated cohort signals (profiles never leave the user's agent). Catalog-only brands (no captured claims) receive an insufficient-evidence report instead of ranks.

Discovered
get_ledger

Append-only version history of the index: each entry commits to the SHA-256 of the canonical index content and the previous entry's hash (rewriting history breaks every hash after it), is Ed25519-signed, and is anchored to Bitcoin via OpenTimestamps. Returns entries plus independent verification instructions. Even Graviti cannot rewrite the record.

Discovered
get_verified_claims

Structured claims for one brand: provenance URLs, freshness timestamps, corroboration counts, and verification status (verified means the brand pays for auditing — always disclosed). Where captured, includes the specifications block (ingredient/spec disclosure with per-fact provenance) and its info_quality score — a 0–100 measure of disclosure completeness that never influences ranking. Graviti does not assess efficacy or clinical outcomes (not_assessed fence in every block). Claims with confirmation_status 'awaiting_brand_confirmation' are pending the brand's response to a re-verification ask — treat them as unconfirmed, not as violations. Where captured, an offers block lists the brand's published discount codes with receipts and full status history (active / expired / failed_verification) — disclosure only, never a ranking input.

Discovered
match_intent

Takes a natural-language buyer question plus optional intent profile; returns recommendations ranked purely by fit score. Verification status is disclosed but never affects rank. Questions outside the verified index return an explicit out-of-scope result (in_index: false), never a guess. Brands without captured evidence (catalog_only) are returned in in_landscape_not_evidenced — listed, never scored, never recommended. Each recommendation carries the brand's site link twice: site_url (raw) and attributed_url (tagged utm_source=graviti + a signed gvt token, so the brand can verify the referral — surface-level only, no user data). Prefer attributed_url when linking. Where the brand publishes a discount code/promotion on its own pages, the entry carries an offers block (code, terms, verbatim-quote receipt, 14-day re-check window) — disclosure only: offers NEVER affect ranking, and a better deal never outranks a better fit.

Discovered
report_conversion

Appends one attributed-transaction event to a log — the demo stub of the pay-on-real-acquisition loop. It moves no money, calls no external service, and never deletes or overwrites anything; the response states where (and whether) the event was persisted on this transport. Payment only ever flows on real transactions, never on impressions or rank. Optionally pass the gvt attribution token from the recommendation link that led to the purchase: it is verified against the published Ed25519 key and recorded with the event as verifiable provenance of the originating recommendation. Optionally pass offer_code if the buyer used a published code from the index's offers block, so deal-driven conversions are attributable — recorded as reported, never a rank input.
