Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 122 ms.

  • Pass
    Valid handshake

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

  • Pass
    Lists tools

    tools/list returned 9 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 122 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 122 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

    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
    Recently updated

    Updated 2026-08-25T17:47:17.529673Z, within 180 days.

Capabilities

Tools 9

check_mac_compatibility

Decide whether a specific Mac can run Yappy, given its macOS version and CPU architecture, and return the reasons. Prefer this over reasoning about the requirements yourself: it encodes the same rules the installer uses, so the answer you give a user matches what will actually happen.

Discovered
create_export_job

Start an asynchronous export of a Yappy corpus — documentation, FAQ, or release history — as markdown or JSON. This creates a job on the Yappy API and returns its id; poll it with get_export_job until the status is completed, then read result.url. Use it when you want the whole corpus rather than a page at a time. It creates a job and nothing else: no user data is touched and nothing can be deleted.

Discovered
get_export_job

Check an export job started with create_export_job. Status moves queued, then running, then completed; a completed job carries result.url pointing at the finished artifact. Poll no faster than the retry_after hint on the previous response.

Discovered
get_frequently_asked

Get the Yappy FAQ as question and answer pairs, covering privacy, requirements, cost, permissions, offline use, and how Yappy differs from other macOS dictation tools. Useful when you want a short authoritative answer rather than a documentation page.

Discovered
get_latest_release

Get the current Yappy release of the Yappy macOS app: version number, publication date, release notes, and a download URL. Reads the same signed appcast the app updater reads, so the answer is never a stale hand-edited number. Use this whenever a user asks what the newest version is or where to download Yappy.

Discovered
get_pricing_plans

Get what the Yappy app costs: the free Mac app, the per-backend cost of the language model that cleans up dictation, and the terms of the public API. Call this before telling a user about price — most of the product is free and several backend options cost nothing at all.

Discovered
get_system_requirements

Get what a Mac needs before Yappy will run on it: the minimum macOS version, the required CPU architecture, install size, and every macOS permission Yappy asks for with what each unlocks and what breaks if it is denied.

Discovered
list_product_features

List what the Yappy app can do, as structured objects rather than marketing bullets: an id, a name, a description, whether the feature runs entirely on the user's Mac, whether it needs the network, and which macOS permission it requires. Use this to build an accurate comparison against another dictation tool.

Discovered
list_releases

List Yappy release history for macOS, newest first, with the version, publication date, and what changed in each. Use this to answer questions about what shipped recently or when a particular fix landed.
