Webhook Signature Fixture Lab

Overview

Webhook Signature Fixture Lab is an MCP server that generates deterministic webhook HMAC-SHA256 fixtures and optionally verifies a supplied signature. It works as a tool within your AI assistant, letting the model handle fixture creation and signature validation tasks without manual intervention.

The server runs as a remote endpoint at https://mcp-factory.bowling-anthony.workers.dev/webhook-signature-fixture-lab/mcp with no local installation needed. It requires no authentication to connect. The current release is v0.1.0, available from the vendor website at https://mcp-factory.bowling-anthony.workers.dev/webhook-signature-fixture-lab.

Webhook Signature Fixture Lab is listed in the Development category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing here to verify ownership and keep information up to date.
