We couldn’t confirm it starts correctly

The install command started, but didn't respond the way we expected when we tried to talk to it.

npx -y @4da/mcp-server

initialize succeeded but no response to tools/list.

This is an experimental automated check and can have false negatives — missing environment variables, a slow cold install, etc. It doesn’t necessarily mean something’s wrong. Last checked 2d ago.

Overview

runyourempire/4DA connects AI coding agents to dependency intelligence backed by the app's database. Its 14 tools cover live CVE scanning, dependency health checks, upgrade planning, ecosystem news, and decision memory. Install it as a zero-configuration npm MCP process, or add it as a Claude Code plugin. Reach for it when an agent needs current dependency-risk context alongside coding work.

Use cases

  • Scan project dependencies for live CVEs
  • Assess dependency health before a release
  • Plan dependency upgrades with an AI coding agent
  • Track relevant ecosystem news
  • Recall prior dependency decisions

Key features

  • Live CVE scanning
  • Dependency health analysis
  • Upgrade planning
  • Ecosystem news
  • Decision memory
  • 14 MCP tools

How 4DA works

What runyourempire/4DA MCP server does

runyourempire/4DA gives AI coding agents access to dependency intelligence through the Model Context Protocol. Its focus is software supply-chain and maintenance context: identifying current CVEs, assessing dependency health, planning upgrades, tracking ecosystem news, and retaining decisions made during dependency work.

The server is distributed as the @4da/mcp-server npm package. The source repository shown by older links is a compatibility location; ongoing issues, releases, and contributions belong to the 4DA Systems repository.

How it works

The MCP process reads the 4DA app's database and exposes 14 tools to an MCP-compatible client. The database schema used by the server is published with the application as src-tauri/contract/app-schema.sql. That schema is generated from migrations, and CI checks application schema changes against the server's queries before they are merged.

This design gives agents access to the dependency data maintained by the 4DA application rather than requiring each agent workflow to implement its own dependency intelligence layer. The server is described as privacy-first and requires no configuration for its standard installation path.

Setup and configuration

The package can be registered with Claude Code using:

Terminal
claude mcp add 4da -- npx @4da/mcp-server

It can also be installed as a Claude Code plugin:

Terminal
claude plugin marketplace add 4DA-Systems/4da-mcp-server
claude plugin install 4da@4da

The npm package name remains @4da/mcp-server, even though the server's source has moved to its own repository. No environment variables or additional configuration are required for the documented installation.

Tools and capabilities

The toolset contains 14 tools spanning:

  • Live CVE scanning for dependency-related vulnerabilities
  • Dependency health analysis
  • Upgrade planning
  • Ecosystem news relevant to dependencies
  • Decision memory for retaining dependency-related context

These capabilities suit coding agents that need to inspect dependency risk, evaluate maintenance status, determine upgrade steps, or recall earlier decisions while working on a codebase.

Limitations and notes

The server depends on the 4DA application's database and its published schema. Changes to that schema are validated against the server's queries in CI, so the app database and server are designed to evolve together.

The repository at runyourempire/4DA remains available for older links, but the active server repository is maintained under 4DA Systems. Installation continues to use the same npm package name.

Frequently Asked Questions about 4DA

runyourempire/4DA is an MCP server that connects AI coding agents to the 4DA app's dependency database. Its 14 tools provide live CVE scanning, dependency health analysis, upgrade planning, ecosystem news, and decision memory, giving agents dependency-maintenance context through a standard MCP interface.

Install it with `claude mcp add 4da -- npx @4da/mcp-server`. The package name is `@4da/mcp-server`, and the standard installation requires no additional configuration.

Install it as a Claude Code plugin with `claude plugin marketplace add 4DA-Systems/4da-mcp-server` followed by `claude plugin install 4da@4da`. The plugin is maintained from the server's current 4DA Systems repository.

It handles live CVE scanning, dependency health checks, upgrade planning, ecosystem news, and decision memory. These capabilities help coding agents investigate dependency risk and retain context about maintenance choices.
