Blackwall

Overview

Blackwall is a Model Context Protocol (MCP) server: API-key pre-action risk gate: any irreversible agent action (money, SQL, delete, email). Because it speaks the Model Context Protocol, AI assistants can use Blackwall as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package blackwall-mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need BLACKWALL_API_KEY. The current release is v1.4.2, with source at bluetieroperations-create/blackwall-mcp on GitHub.

On mcp.site, Blackwall sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
