Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 2814 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name viasocket-mcp.

  • Pass
    Lists tools

    tools/list returned 5 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 2814 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 2814 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

    11 of 11 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.

  • 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

    Updated 2026-10-30T11:21:20.787911Z, within 180 days.

Capabilities

Tools 5

call_any_api_of_msg91

Send a POST, PUT, PATCH or DELETE request to any MSG91 API endpoint for the user and return its response. Use it once you know the exact endpoint: look it up with get_msg91_api_docs first to get its URL, headers, query params and body, unless the skill or a dedicated tool on this server already gives them exactly. Load the quickstart-msg91 skill first: it explains which tool to use when. For GET requests use call_any_read_api_of_msg91. Pass the full url with path variables filled in, the headers the docs list, query params in `query` (not in the url) and the JSON body in `body`. For the auth header the docs name (Authorization, proxy_auth_token, x-api-key, ...), pass it with an empty value "": the signed-in user's token is filled in automatically. Never put a real or made-up token there; if the docs name no auth header, leave it out and the token is sent as Authorization. If the API needs the user to sign in, they're asked the first time. Returns { status, ok, headers, data }: the HTTP status and the response body, including error details on failure.

get_msg91_api_docs

Browse the MSG91 API docs, one level at a time. Call it without arguments to get the top level: the modules and pages with a short description and the endpoints they hold. Call it with `path` set to a module's or page's link (or path) to get what is inside it; each listing links the next level. Call it with `path` set to an endpoint's link ending in ".openapi.yml" to get that endpoint as an OpenAPI file: method, url, headers, query params, path variables, a request body example and sample responses. Fetch only the level you need.
