What you can do with the Svix MCP server

Ask your agent in plain language. Each of these maps to a real tool on the server.

  • Use the resend message tool in Svix
  • Use the update application tool in Svix
  • Use the list attempts by message tool in Svix
  • Use the list messages tool in Svix
  • Use the get application tool in Svix
  • Use the send message tool in Svix

Supported Tools

resend_message

Resend Message

Manually resend a specific message to a specific endpoint. Use this to retry a single failed delivery without recovering all messages.

update_application

Update Application

Update an existing consumer application's name, UID, rate limit, or metadata. Provide the application ID or UID to identify which application to update.

list_attempts_by_message

List Attempts by Message

List delivery attempts for a specific message. Shows the status, response, and endpoint for each attempt. Use this to debug delivery failures or verify successful delivery.

list_messages

List Messages

List webhook messages sent to an application. Filter by event type, channel, or time range. Use this to audit message history or debug delivery issues.

get_application

Get Application

Retrieve details of a specific consumer application by ID or UID. Returns the application's name, metadata, rate limit, and timestamps.

send_message

Send Message

Send a webhook message to a specific application. The message will be dispatched to all matching endpoints of that application. Optionally auto-create the application if it doesn't exist by including application details.

delete_application

Delete Application

Permanently delete a consumer application and all its associated endpoints and messages. This action cannot be undone.

delete_event_type

Delete Event Type

Archive (soft-delete) an event type. Archived event types are hidden from consumers but can still be referenced by existing messages.

get_endpoint_stats

Get Endpoint Stats

Get delivery statistics for a specific endpoint including counts of successful, pending, failed, and sending attempts. Also retrieves the endpoint's signing secret for webhook verification.

list_event_types

List Event Types

List registered event types in your Svix environment. Event types categorize webhook messages and allow consumers to subscribe to specific events.

list_endpoints

List Endpoints

List all webhook endpoints for a specific application. Returns endpoint URLs, filtering configuration, and status.

create_application

Create Application

Create a new consumer application in Svix. Applications represent your customers and are the target for webhook messages. Assign a custom UID (e.g., your internal customer ID) to enable stateless usage without storing Svix IDs.

create_endpoint

Create Endpoint

Create a new webhook endpoint for an application. Endpoints are target URLs that receive webhook messages. Configure event type filtering, channels, and custom headers.

list_applications

List Applications

List consumer applications in your Svix environment. Applications represent your customers, each receiving their own webhook messages. Use this to browse or search for applications before managing their endpoints or messages.

update_endpoint

Update Endpoint

Update an existing webhook endpoint's URL, event type filters, channels, rate limit, or other configuration.

delete_endpoint

Delete Endpoint

Permanently delete a webhook endpoint from an application. The endpoint will no longer receive messages.

get_portal_access

Get Portal Access

Generate a short-lived App Portal URL for a specific application. The portal lets your customers manage their endpoints, debug delivery, and inspect/replay past webhooks — all without needing a Svix account.

list_attempts_by_endpoint

List Attempts by Endpoint

List delivery attempts targeting a specific endpoint across all messages. Useful for diagnosing endpoint health and delivery patterns.

recover_failed_messages

Recover Failed Messages

Bulk-recover all failed messages for an endpoint since a given date. This resends all messages that have exhausted their retry attempts. Use this after an outage or endpoint misconfiguration to replay missed webhooks.

create_event_type

Create Event Type

Register a new event type in Svix. Event types are the primary way for webhook consumers to configure which events they receive. Optionally include a JSONSchema (Draft 7) to define the expected payload shape.

get_endpoint_transformation

Get Endpoint Transformation

Retrieve the JavaScript transformation configured for an endpoint and whether it is enabled.

get_message

Get Message

Retrieve a webhook message by Svix message ID or event ID. Optionally include the payload content for debugging or audit workflows.

update_event_type

Update Event Type

Update an event type's description, schemas, archive/deprecation state, feature flags, or group name.

import_event_types_from_openapi

Import Event Types From OpenAPI

Create or update Svix event types from an OpenAPI document's webhooks section. Supports dry runs to preview changes without modifying event types.

get_endpoint_secret

Get Endpoint Secret

Retrieve an endpoint's webhook signing secret for signature verification.

precheck_message

Precheck Message

Check whether a message with the given event type and channels would be sent to any active endpoint before creating it.

get_event_type

Get Event Type

Retrieve an event type by name, including schemas, feature flags, grouping, and lifecycle state.

update_endpoint_headers

Update Endpoint Headers

Replace the custom HTTP headers sent with webhook deliveries for an endpoint.

get_endpoint_headers

Get Endpoint Headers

Retrieve the custom HTTP headers configured for a webhook endpoint, including the names of sensitive headers that Svix redacts.

update_endpoint_transformation

Update Endpoint Transformation

Set, unset, enable, or disable the JavaScript transformation associated with an endpoint.

expunge_message_content

Expunge Message Content

Delete the stored payload for a message while preserving delivery metadata. Use this for retention and privacy workflows.

get_endpoint

Get Endpoint

Retrieve a webhook endpoint's URL, filtering, throttle, status, metadata, and timestamps by ID or UID.

rotate_endpoint_secret

Rotate Endpoint Secret

Rotate an endpoint's webhook signing secret. Provide a specific secret or omit it to let Svix generate one.

Connect Svix to your AI client

Every client uses the same Magic MCP URL, and so does any other MCP client. Add it once and sign in with SSO.

  1. Enable Svix in Metorial. In your Metorial portal, enable the Svix MCP server and sign in with the account that owns the data. Access stays governed by your team policies.
  2. Add a custom connector. Open Customize, then Connectors. Select Add, then Custom, then Web.
  3. Paste your Metorial MCP URL. Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>) and continue.
  4. Sign in. Select Add and sign in to load Svix tools.

Run Svix through the Metorial gateway

One governed layer for every app your agents reach, not a separate connector per tool.

  • Give Svix and every other app to your whole team through one MCP gateway, behind your SSO.
  • Scope which teams and agents can use Svix tools with role-based access control, and trace every call.
  • Prefer to run it yourself? Metorial is open source and self-hostable.
