Everything Claude Code ( Everything Claude Code MCP ) provides an agent harness performance system that couples memory optimization, continuous learning, verification loops, and subagent orchestration to run AI agent harnesses across Claude Code, Codex, Cowork, and other harnesses. This MCP server uses ECC’s universal tooling to deploy and orchestrate skills, hooks, and configuration rules as a cohesive runtime. After starting the server, you can use the included ECC commands to load skills, configure memory persistence, and run harness loops that manage model routing, evaluation, and optimization throughout a session.

Prerequisites:

• Node.js and npm installed on your system
• Access to the npm registry (public or private as configured)

Installation steps:

1. Install the ECC universal package via npx (no local install needed): npm i -g npm@latest npx -y ecc-universal

2. If you prefer a local setup, install the package locally in your project: mkdir -p your-project && cd your-project npm init -y npm install ecc-universal

3. Run the MCP server using the recommended command (see mcp_config): npx -y ecc-universal

4. Verify installation: npx ecc-universal --version

Notes:

• Ensure your environment has network access to fetch the ECC packages
• You may need to configure environment variables for security or storage backends as described in the documentation

Tips:

• ECC_HOOK_PROFILE and ECC_DISABLED_HOOKS can gate runtime behavior without editing hook files.
• Use the /harness-audit, /loop-start, /loop-status, /quality-gate, /model-route commands to manage harness runs.
• For cross-harness consistency, ensure memory persistence and skill hot-load features are enabled in your config.
• Check environment variables for memory persistence and evaluation strategies to fine-tune performance.

Common issues:

• Network errors when fetchingECC packages; verify npm registry access.
• Version mismatches betweenECC components; align ECC package versions across your setup.
• Permissions errors when writing session data; ensure the process user has write access to storage paths.
