Overview

AI-generated overview

Relin is a remote MCP server for webhook operations: receiving vendor events, delivering outbound webhooks to customer endpoints, and inspecting or replaying.

What you can do
Explain Relin's webhook intake, delivery, replay and anomaly review, and list supported vendor webhook shapes with setup guidance and API key management (list, create, revoke). Manage incoming sources: create, rotate ingest tokens, archive, and check setup status with provider authorization links. Manage outbound apps, recipients, endpoints, event types and portal settings and hosts. Send outbound webhook messages, read message history and delivery attempts, and replay messages. Inspect recent received events, duplicates and signature status.
When to use it
Use it when an assistant should operate a Relin workspace: wiring up incoming vendor webhooks, configuring customer-facing outbound endpoints, or diagnosing and retrying failed deliveries.
Requirements
A remote streamable HTTP endpoint at relin.app; no local runtime, packages, environment variables or headers are declared. Most tools are marked authenticated, so a Relin account and workspace access are needed.
Before you install
Many tools write, change or delete data: archiving a source deletes its stored records and cancels queued retries; deleting an endpoint disables deliveries; rotating tokens and secrets returns replacements once. Sending or replaying messages can trigger actions at customer endpoints, and an accepted message is not proof of delivery. Portal session links grant access to a customer's webhook controls. Stripe setup returns an account authorization link.

Installation

In SourceWeft

  1. Open Relin in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.earonesty%2Frelin/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
