Audit MCP server

mcp-audit-server

Thin MCP server and CLI proxy for AI agent and MCP security auditing. It connects to a private audit API to analyze MCP configurations, test prompt injection resistance, trace data flows, scan packages, and generate security policies.

This package is a thin proxy. All scan logic lives in a private backend operated by you or your provider.

Managed hosted flow:

• set AGENTSECURITYAPI_KEY
• the package will automatically target https://audit.leddconsulting.com

Self-hosted or private-network flow:

• set AGENTSECURITYBASE_URL to your HTTPS API origin
• or set AGENTSECURITYHOST and AGENTSECURITYPORT for a loopback/private deployment

Hosted backend access is not bundled with this package. If you want managed access or a licensed private deployment, contact Ledd Consulting.

Registry and Directories

• npm package: ledd-mcp-audit-server
• Official MCP Registry name: io.github.joepangallo/mcp-audit-server
• Downstream directories such as Glama and PulseMCP should ingest from the official MCP Registry, so you usually do not need separate manual submissions for each site.
• Glama authorship claim is optional. It only gives you ownership of the Glama page and access to manual sync and re-scan controls.

Install

npm install ledd-mcp-audit-server

Install package: ledd-mcp-audit-server CLI command after install: mcp-audit-server

This is the public package that should be published to npm and listed in public MCP directories. The audit engine itself stays private.

The old package name mcp-server-agent-security is retired. See MIGRATION.md for upgrade steps and the deprecation plan.

Usage as MCP Server

Add to your MCP client configuration (Claude Desktop, Cursor, etc.):

{
  "mcpServers": {
    "mcp-audit-server": {
      "command": "npx",
      "args": ["-y", "ledd-mcp-audit-server", "--mcp"],
      "env": {
        "AGENT_SECURITY_API_KEY": "your-issued-api-key"
      }
    }
  }
}

For a self-hosted backend, add AGENTSECURITYBASE_URL to that same env block.

The server exposes 10 tools over stdio:

Usage as CLI

The CLI forwards commands to the private audit API.

# Hosted quick start
export AGENT_SECURITY_API_KEY=your-issued-api-key

# Audit an MCP configuration file
mcp-audit-server scan-config ./claude_desktop_config.json

# Probe a live MCP server (requires AGENT_SECURITY_ADMIN_MODE=1)
mcp-audit-server scan-server npx -y @modelcontextprotocol/server-filesystem /tmp

# Audit trust posture and policy drift for an agent/MCP deployment
mcp-audit-server scan-trust ./claude_desktop_config.json ./claimed-policy.json

# Scan an npm package for vulnerabilities
mcp-audit-server scan-package @modelcontextprotocol/server-shell
