What is the ParticlePhysics MCP Server?

A Model Context Protocol server that lets Claude Desktop, IDEs, and other MCP clients look up particle properties and decay modes.

What you get

  • search_particle — mass (MeV + GeV), charge, spin, color, parity / C / I / G,
  • list_decays — exclusive / inclusive branching fractions with the source method named
  • Natural-language input — muon plus, positive tau, pion zero, kaon minus
  • Anti-particle support — antimuon, anti up quark, ubar, u bar, u_bar, u~,
  • MC ID lookup — query directly with 11, -2212, etc
  • Self-conjugate aware — anti photon resolves to gamma, anti pi0 to pi0

search_particle1. mu Name: mu+ PDG ID: -13 PDG Review ID: S004/2025 Mass: 105.6583755 MeV (0.1056583755 GeV) Spin (J): 1/2 Charge: 1 Color: singlet Quantum numbers: J=1/2 Lifetime: 2.196981148893498e-06
list_decaysSame identifier formats as search_particle. Tries exclusive_branching_fractions → branching_fractions → inclusive_branching_fractions and reports which source it used. Returns an empty decay list with stable=true for sta
