Aegis MCP Server

Stop putting API keys where AI agents can read them. Aegis is a local-first credential isolation proxy for AI agents. It sits between your agent and the APIs it calls - injecting secrets at the network boundary so the agent never sees, stores, or transmits real credentials.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Aegis

before you install - you'll need

SLACK_TOKEN

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add getaegis-aegis -- npx -y @getaegis/cli

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "getaegis-aegis": {
      "command": "npx",
      "args": [
        "-y",
        "@getaegis/cli"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

What is Aegis?
