Killcord

Overview

Killcord is a Model Context Protocol server that acts as a dead-man's switch for your Anthropic API spend. It automatically kills your API key the instant it crosses a spending limit you set, protecting you from runaway costs. The server exposes this functionality as tools that MCP clients can invoke on your behalf.

Killcord runs as a remote hosted service at https://www.edgethirteen.com/api/mcp/killcord with no authentication required and nothing to install locally. The latest release is v1.0.0. Simply point your MCP client to the endpoint and you're connected.

Killcord is listed in the AI & Agents category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain Killcord for edgethirteen.com, claim this listing to verify ownership and keep the information current.
