Zikkaron · Summary

Biologically-inspired persistent memory engine for Claude Code with 26 cognitive subsystems, local SQLite storage, and advanced memory recall capabilities.

everything · Summary

Official MCP test server exercising all protocol features for client builders.

Zikkaron · Use cases

Long-term code projects where context needs to persist across sessions
Complex debugging sessions where Claude needs to remember previous approaches
Multi-session development where architectural decisions must be preserved
Teams working on shared codebases with consistent implementation patterns

everything · Use cases

Testing MCP client implementations against all protocol features
Learning MCP protocol capabilities through a reference server
Validating client compatibility with different transport methods

Zikkaron · Install

pip install zikkaron

Add to your Claude Code config:

{
  "mcpServers": {
    "zikkaron": {
      "command": "zikkaron"
    }
  }
}

Tell Claude how to use it by adding instructions to your global ~/.claude/CLAUDE.md:

## Memory
- On every new session, call `recall` with the current project name
- Before starting any task, call `get_project_context` for the current directory
- After completing significant work, call `remember` to store decisions and outcomes

NPX (recommended)

{
  "mcpServers": {
    "everything": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-everything"]
    }
  }
}

On Windows, use cmd /c:

{
  "mcpServers": {
    "everything": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "@modelcontextprotocol/server-everything"]
    }
  }
}

Docker

{
  "mcpServers": {
    "everything": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "mcp/everything"]
    }
  }
}

Global install

npm install -g @modelcontextprotocol/server-everything@latest
