    Valid handshake

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

  • Pass
    Lists tools

    tools/list returned 19 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 57 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 57 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

    77 of 77 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.

  • 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 2026-11-10T23:33:36.317889Z, within 180 days.

svix_create_application

Create a new application (one tenant/customer of yours) in the Svix environment. Svix REST: POST /api/v1/app.

Fetch a single webhook endpoint, including its URL, subscribed event types and channels. Svix REST: GET /api/v1/app/{app_id}/endpoint/{endpoint_id}.

Discovered
svix_get_endpoint_stats

Read delivery statistics for one endpoint — counts of success, pending, sending and fail. The fastest way to see whether an endpoint is healthy. Svix REST: GET /api/v1/app/{app_id}/endpoint/{endpoint_id}/stats.

Discovered
svix_get_event_type

Fetch a single event type by name, including its description and JSON schema. Svix REST: GET /api/v1/event-type/{event_type_name}.

Discovered
svix_get_message

Discovered
svix_list_endpoints

List the webhook endpoints registered for one application. Svix REST: GET /api/v1/app/{app_id}/endpoint.
