Radio-isotope production, activity and dose for charged-particle beams on stacked targets

MCP Server: io.github.exoma-ch/hyrr

The io.github.exoma-ch/hyrr MCP server describes radio-isotope production details, including activity and dose for charged-particle beams applied to stacked targets. It is focused on representing domain-specific outputs relevant to beam irradiation scenarios and how produced isotopes relate to resulting dose.

🛠️ Key Features

Provides information related to radio-isotope production
Includes activity and dose for charged-particle beams
Targets calculations or reporting for stacked targets

🚀 Use Cases

Production planning or documentation for radio-isotopes
Estimating activity and dose under charged-particle irradiation
Modeling results for stacked target setups

⚡ Developer Benefits

Structured access to beam-target activity and dose context
Clear domain scope tied to charged-particle beams and stacked targets

⚠️ Limitations

Only the server’s description is available; no additional tool capabilities, endpoints, or usage details are provided here.

hyrr-mcp

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

Listed in the official MCP Registry as io.github.exoma-ch/hyrr.

Install and register with Claude Code:

bash

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.

Install

Configuration

Environment variables

HYRR_DATA

nucl-parquet data directory. Unset: the matching data release is fetched once into ~/.hyrr/nucl-parquet

HYRR_LIBRARY

Nuclear data library id, e.g. tendl-2023-iso (default) or endfb-8.1
