01 · Install Code Context Engine

Claude Code

claude mcp add elara-labs-code-context-engine -- uvx code-context-engine

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "elara-labs-code-context-engine": {
      "command": "uvx",
      "args": [
        "code-context-engine"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package code-context-engine - check the name against the project README before installing (PyPI has no namespace ownership)

registry registry publisher io.github.ai-elara is not the repo owner (elara-labs) - the registry entry was published by someone else
