01 · Install Particles

before you install - you'll need

Set ANTHROPIC_API_KEY before connecting.

Claude Code

claude mcp add linkedparticles-particles-engine-py -- uvx linkedparticles

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "linkedparticles-particles-engine-py": {
      "command": "uvx",
      "args": [
        "linkedparticles"
      ]
    }
  }
}

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

repo age created 2026-08-09 - young repo, little track record yet

license Apache-2.0 - declared in the repository

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

registry vendor namespace org.linkedparticles - domain-verified with the official MCP registry
