OfficialServer Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| HICAR_REPO | No | Absolute path to a HICAR checkout for source-aware tools and fresh metadata. | |
| HICAR_BINARY | No | Path to a compiled HICAR binary for binary-based validation. | |
| OPENAI_API_KEY | No | API key for OpenAI to enable higher-quality semantic search. | |
| VOYAGE_API_KEY | No | API key for VoyageAI to enable higher-quality semantic search. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_namelist_groupsA | List HICAR namelist groups (&blocks) with option counts. |
| list_namelist_optionsC | List namelist options, optionally filtered to one group. |
| get_namelist_optionB | Full metadata for one namelist option: group, &block, type, default, allowed values, range, units and description. |
| search_namelist_optionsB | Search namelist options by name/description (substring). |
| validate_namelistA | Validate a namelist string. Static checks always run (unknown groups/options, bad enum values, out-of-range, type/per-nest issues). If use_binary and a compiled HICAR is available, also run --check-nml. |
| generate_namelist_toolB | Generate a namelist ('full' or 'minimal') with optional physics scheme selections. With use_binary, delegate to HICAR --gen-nml instead. |
| explain_namelistA | Parse a namelist and annotate every option with its description, type, default and allowed values; flag any validation issues. |
| list_physics_categoriesA | List physics-scheme categories (microphysics, pbl, radiation, ...). |
| get_physics_schemesA | List selectable schemes for a category (or selector like 'mp'), with codes, originating constants, and supported status. |
| resolve_physics_schemeC | Resolve a scheme name or integer code within a category. |
| list_model_variablesB | List kVARS model/output variables (optionally substring-filtered). |
| get_model_variableA | Full metadata for a model variable (by netCDF name or kVARS member). |
| search_model_variablesA | Search model variables by name/standard_name/description. |
| list_example_namelistsB | List bundled example namelists. |
| get_example_namelistC | Return the contents of an example namelist. |
| search_example_namelistsC | Search example namelists for a substring. |
| list_docsA | List HICAR documentation pages. |
| get_docC | Return a documentation page by file name or title. |
| search_docsC | Search the documentation (substring, with doc + line refs). |
| code_searchA | Lexical search over HICAR source (.F90) and docs. Requires HICAR_REPO (live mode) for source; bundled mode searches docs only. |
| find_symbolB | Find Fortran symbols (module/subroutine/function/type) by name. Requires HICAR_REPO (live mode). |
| read_sourceA | Read HICAR source by file path (repo-rooted, line range) or by symbol name. Requires HICAR_REPO (live mode). |
| semantic_searchC | Natural-language semantic search over HICAR code + docs. Falls back to lexical search if the embedding model isn't available. |
| server_statusA | Report server mode, discovered paths, artifact/HICAR version, and which optional features (binary, ripgrep, semantic) are active. |
Prompts
Interactive templates invoked by user choice
| Name | Description |
|---|---|
| configure_hicar_run | Guided prompt to build a HICAR namelist for a described use case. |
| debug_namelist_error | Guided prompt to diagnose a HICAR namelist/runtime error. |
| explain_physics_choice | Compare the available schemes in a physics category. |
