Project description

hyrr-mcp

HYRR MCP server — stdio JSON-RPC for radio-isotope production queries.

Install and register with Claude Code:

claude mcp add hyrr -- uvx hyrr-mcp

The first invocation downloads the wheel (or builds from source if no wheel exists for your platform); subsequent runs are instant.

Data resolution priority: --data-dir arg → HYRR_DATA env → sibling nucl-parquet/ → ~/.hyrr/nucl-parquet.

The tools surface (simulate, list_materials, list_reaction_channels, get_decay_data, compare_simulations, get_stack_energy_budget, get_stopping_power, get_isotope_production_curve) is implemented in Rust in hyrr-core::mcp; this package is a thin PyO3 wrapper used purely for distribution.
