## Tools (as reported by the server, not verified)

- `describe\_relin`: Explain what Relin does and how agents should use it for webhook intake, delivery, replay, and anomaly review.
- `list\_supported\_webhook\_shapes`: List the vendor webhook shapes Relin understands for event identity, ordering, and gap checks.
- `get\_setup\_guide`: Return concise setup guidance for connecting a webhook source and destination.
- `list\_api\_keys`: Authenticated tool to list API keys.
- `create\_api\_key`: Authenticated tool to create API key.
- `revoke\_api\_key`: Authenticated tool to revoke API key.
- `list\_sources`: Authenticated tool to list sources.
- `create\_source`: Authenticated tool to create source.
- `rotate\_source\_token`: Authenticated tool for rotating an ingest token and returning the replacement URL once.
- `archive\_source`: Delete an incoming webhook source and its stored records, stop intake and delivery, and cancel its queued retries. Use only when the user intends to remove that source.
- `list\_destinations`: Authenticated tool for listing outbound destinations and retry policy.
- `create\_destination`: Authenticated tool for creating an outbound destination and connection with retry policy and optional filters.
- `list\_apps`: List outbound webhook applications in the connected Relin workspace. Use this to find the app ID before managing customer endpoints or sending events.
- `create\_app`: Create an outbound webhook application for a product or environment. Use when the user needs a new set of customer webhook endpoints.
- `get\_app`: Read an outbound webhook application by its app ID to inspect its configuration.
- `list\_recipients`: List customers configured to receive outbound webhooks for an app. Use returned customer identifiers for endpoint and message operations.
- `upsert\_recipient`: Authenticated tool for creating or updating a recipient.
- `list\_endpoints`: List customer webhook endpoints and delivery settings for an outbound app.
- `create\_endpoint`: Add an HTTPS webhook endpoint for a customer of an outbound app. Configure event subscriptions and retry settings using the requested customer and URL.
- `get\_endpoint`: Read a customer webhook endpoint, its event subscriptions, and delivery settings.
- `update\_endpoint`: Change a customer webhook endpoint URL, event subscriptions, signing settings, retry policy, or enabled state. Changes can interrupt or redirect future deliveries.
- `delete\_endpoint`: Disable a customer webhook endpoint so it no longer receives events.
- `rotate\_endpoint\_secret`: Authenticated tool for rotating the signing secret for one endpoint.
- `list\_messages`: List outbound webhook messages for an app, optionally filtered by customer or event type. Use this for send history rather than incoming vendor events.
- `send\_message`: Send a webhook event from an outbound app to the specified customer. Requires the intended app, recipient, event type, and payload. Delivery can trigger actions at customer endpoints; an accepted message is not proof of delivery.
- `get\_message`: Read one outbound webhook message and its delivery state using the app and message IDs.
- `list\_message\_attempts`: Inspect delivery attempts for an outbound webhook message, including returned status and errors. Use this to verify delivery or diagnose failures.
- `replay\_message`: Send an existing outbound webhook message again. May repeat actions at customer endpoints; use only for the message the user wants replayed.
- `list\_event\_types`: List the event types customers can subscribe to for an outbound app.
- `upsert\_event\_type`: Create or update an outbound event type and its description for customer webhook subscriptions.
- `delete\_event\_type`: Archive an outbound event type so customers can no longer select it for new subscriptions.
- `create\_portal\_session`: Create a temporary customer webhook portal link for the specified app and recipient. The link grants access to that customer’s webhook controls; share only with the intended user.
- `get\_portal\_settings`: Authenticated tool for reading portal branding defaults and host setup for an app.
- `save\_portal\_settings`: Authenticated tool for saving portal branding defaults for an app.
- `list\_portal\_hosts`: Authenticated tool for listing stable portal hosts for an app.
- `create\_portal\_host`: Configure a customer webhook portal on a domain the user controls, with their existing OpenID Connect identity provider. Use only when the user asks to set up a portal domain and supplies the application and identity-provider configuration. This creates portal access configuration and may provision
- `check\_portal\_host`: Authenticated tool for refreshing hostname, certificate, and OIDC readiness for a stable portal host.
- `get\_webhook\_setup\_status`: Check a source's provider connection, enabled destinations, recent signature-verified events, and delivery attempts. For Stripe, returns a secure authorization link when needed. Call again after the user connects, without recreating or rotating anything.
- `ensure\_webhook\_setup`: Set up incoming webhooks and delivery rules. For Stripe, returns the account authorization link and connection status; after authorization, use get\_webhook\_setup\_status to verify receipt and delivery. Other providers receive an ingest URL for new sources.
- `list\_recent\_events`: Authenticated tool for inspecting recent received events, duplicates, and signature status.
- `get\_event\_detail`: Authenticated tool for reading one event with attempts, deliveries, and optional raw payload.
- `list\_open\_issues`: Authenticated tool for listing open anomaly and delivery issues. Use q for smart lookup by anom\_, dst\_, evt\_, or src\_ IDs, or plain text like a status code or error message.
- `list\_delivery\_attempts`: Authenticated tool for listing fanout delivery attempts with filters.
- `list\_retry\_jobs`: Authenticated tool to list retry jobs.
- `get\_metrics\_summary`: Authenticated tool for delivery, failure, duplicate, and open-issue rollups.
