Performance

  • Not measured
    Fast (p50)

    Median latency 538 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 538 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 described

    Every tool description is at least 20 characters.

  • Pass

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    12 of 12 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

Capabilities

Tools 3

ask_sync_advisor

Consult CHNLSYNC's advisor about the user's IT environment. First call: omit session_id/session_token and provide company_name plus pain (a plain-language description of what is not working) — a private advisor workspace is created and its credentials are returned. Later calls: pass session_id, session_token AND conversation_id back to continue the same conversation. Persist all three privately across turns. Incomplete continuation handles are rejected before any write; recover the previous tool result instead of creating another workspace. Never automatically retry a failed write: it may already have been recorded. Replies never contain supplier names or pricing — those come only after a human broker review, via the claim_url or a requested callback.

Discovered
check_copper_retirement

Look up US copper/POTS retirement program status by carrier and state. Deterministic read of CHNLSYNC's FCC-sourced dataset (CC BY 4.0 — cite the returned source_url). ``carrier`` accepts display names like "AT&T", "Lumen", "Frontier"; ``state`` is a two-letter abbreviation. Omit both for the full dataset.

Discovered
request_broker_callback

Ask a CHNLSYNC human broker to contact the user about their case. Only call this with the user's explicit consent to share their name and email with CHNLSYNC. Requires the session credentials returned by ask_sync_advisor. The result's ``book_url`` is an optional scheduling link you may offer the user as a next step ("pick a time now"); the callback is already queued and a broker will reach out either way, so never present booking as required or as a confirmed appointment. Do not automatically retry after a timeout: the request may already be recorded.
