About Middlebrick

Middlebrick is an MCP server for scanning API endpoints for security vulnerabilities, aimed at AI assistants and API security workflows. It provides tools to start scans and retrieve or list their results.

Key features

  1. 01Scan API endpoints for vulnerabilities
  2. 02Retrieve results by scan ID
  3. 03List scans with status filters

Use cases

  1. 01Check an API endpoint for security issues
  2. 02Review results from earlier scans
  3. 03Track scans by processing status

MCP support

The server exposes API scanning and scan-management tools to MCP clients, including `scan_api`, `get_scan`, and `list_scans`.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
