How do I install Particles?

Pick a client above and copy the generated config. Cursor and VS Code also have a deep link when the server can run locally or remotely.

Is Particles official?

No. Registry-listed is not the same as vendor-official. Read the methodology for the difference.

How is the trust score calculated?

Particles MCP Server — Install for Claude, Cursor & VS Code | MCPpedia

Environment

Name	Required	Notes
ANTHROPIC_API_KEY	Yes	Anthropic API key. Required for the tools that call a model — `query` composes a cited natural-language answer, and the semantic half of `lint` reasons over claim pairs. The accessors that only read the store (`particle_show`, `particles_list`, `subjects_`, `events_`, `graph_view`, `quality_report`) work without it. Secret.
DATABASE_URL	No	SQLAlchemy URL of the belief store to serve. Defaults to `sqlite+aiosqlite:///./particles.db` in the working directory.
PARTICLES_CONFIG	No	Path to a `config.yaml` holding the rest of the engine's settings — additional stores, model selection per purpose, and the `mcp.write.enabled_stores` allowlist that turns the write tools on.
