Install & config
Client config (built from the install command this repo gives)
{
"mcpServers": {
"affaan-m-ecc": {
"command": "npx",
"args": ["ecc-universal@2.2.3"]
}
}
}Parsed from the README we fetched on 2026-10-26; we have not executed it.
command/args come from the install command the repository states. When it is ambiguous, the project README wins.
VS Code (.vscode/mcp.json - the key is servers)
{
"servers": {
"affaan-m-ecc": {
"command": "npx",
"args": ["ecc-universal@2.2.3"]
}
}
}Same server, but VS Code keeps it under <code>servers</code>.
Claude Code (command line)
claude mcp add --transport stdio affaan-m-ecc -- npx ecc-universal@2.2.3
Claude Code does not read a config file; add the server with this command.

# ECC
Your agent can write code, but ECC gives it a coordinated engineering system and toolbox: it plans before it builds, verifies changes with tests, reviews its own work from a fresh context, remembers what matters, and turns repeated wins into reusable skills and workflows.
text
plan -> test -> implement -> review -> verify -> remember -> improve
Instead of rebuilding that process in every prompt, you install it once and make it part of how your agent works.
> Optimize the context window. Persist everything else.
ECC is MIT-licensed open source. It works best with Claude Code today, has native Codex and Qoder plugin paths, and provides capability-limited adapters for Cursor, OpenCode, Gemini, Zed, GitHub Copilot, Antigravity, Qwen, and other harnesses. See the support status matrix before assuming feature parity.
Access to 71 agents, 311 skills, and 97 legacy command shims, plus hooks, rules, memory, continuous learning, and AgentShield security scanning. The agents are specialized for planning, review, build repair, security, architecture, and domain work.

| Agents | 71 agents | Planning, review, build repair, security, architecture, and domain work |
| Skills | 311 skills | TDD, research, security, docs, frontend, data, ML, operations, and more |
