MCP servers

Extend Nebula with tools from Model Context Protocol servers that you connect, in the console for your workspace or in the CLI for your machine.

On this page

Model Context Protocol servers expose tools Nebula can call, such as your scanners, ticket systems or internal lookups.

In the console

Add MCP servers under Settings, Integrations, in the MCP servers section: connect a remote server, or run a local server in your workspace sandbox. Adding or changing servers needs the mcp:manage member scope.

In the CLI

Add servers for your own machine and projects with breachline mcp add. Project servers shared in a repository’s .mcp.json stay pending until you approve them. See MCP servers in the CLI.

Choosing servers safely

Prefer servers you build or audit. An MCP server runs with whatever access you give it.
Pass credentials as headers or environment variables, never inside prompts.
Review a server’s tools before enabling it for a team.
