Goal

Provide a unified interface for retrieving Metal-Organic Framework (MOF) crystal structures from multiple curated databases. Currently supported:

Database	Alias	Size	Access	Structures
Quantum MOF (QMOF)	`qmof`	~20,000 DFT-relaxed	MPContribs API	DFT-optimized CIFs + bandgaps
ARC-MOF DB7 (Majumdar et al.)	`arcmof-majumdar`	12,316 hypothetical	Zenodo stream	CIFs with REPEAT partial charges

Prerequisites

Environment: base-agent
Packages: mpcontribs-client, requests, pandas, pymatgen
Credentials: MP_API_KEY environment variable (required for qmof only)

Instructions

Step 1: Choose a database and set filters

Decide which database to query and which element/identifier filters to apply.

For QMOF — best for DFT-validated, experimentally-derived MOFs:

Use --formula for element filtering (e.g., Zn or Cu,N,O)
Use --identifier for a specific CSD refcode (e.g., KAXQIL)

For ARC-MOF DB7 (Majumdar et al.) — best for diverse hypothetical MOFs with underrepresented inorganic SBUs:

Use --elements for element filtering (e.g., Zn,O,C)
Use --identifier for a specific structure ID (e.g., DB7_00042)
First run: downloads geometric_properties.csv (~110 MB) to ~/.cache/arcmof/ — one-time only; subsequent runs are fast

Step 2: Run the query

# Env: base-agent
# QMOF — 10 Zn-containing MOFs
MP_API_KEY=<your_key> python .agents/skills/chem-db-mof/scripts/query_mof_db.py \
    --database qmof \
    --formula Zn \
    --max-results 10 \
    --output-dir ./research/<date>_<task>/structures/qmof

# Env: base-agent
# ARC-MOF DB7 (Majumdar) — 20 Zn,O,C hypothetical MOFs
python .agents/skills/chem-db-mof/scripts/query_mof_db.py \
    --database arcmof-majumdar \
    --elements Zn,O,C \
    --max-results 20 \
    --output-dir ./research/<date>_<task>/structures/arcmof_db7

# Env: base-agent
# ARC-MOF DB7 — retrieve a specific structure by identifier
python .agents/skills/chem-db-mof/scripts/query_mof_db.py \
    --database arcmof-majumdar \
    --identifier DB7_00042 \
    --output-dir ./research/<date>_<task>/structures/arcmof_db7

Available Arguments

Argument	Applies to	Description
`--database`	both	`qmof` or `arcmof-majumdar`
`--formula`	qmof	Element/formula filter string (e.g., `Zn,O,C`)
`--elements`	arcmof-majumdar	Comma-separated required elements; ALL must be present
`--identifier`	both	Specific structure name or ID substring
`--max-results`	both	Max CIFs to download (default: 10)
`--output-dir`	both	Directory for output CIF files
`--cache-dir`	arcmof-majumdar	Override default cache `~/.cache/arcmof/`

Step 3: Inspect outputs

The script saves:

Individual .cif files named by structure identifier
arcmof_db7_metadata.csv (ARC-MOF only) — geometric properties for the downloaded subset

Verify the download:

ls -lh <output-dir>/*.cif | head -20

Download Behavior: ARC-MOF DB7

The first call with --database arcmof-majumdar performs:

Metadata download (~110 MB, one-time): geometric_properties.csv cached at ~/.cache/arcmof/
DB7 filtering: identifies the 12,316 Majumdar structures from the full 288k-entry CSV
CIF streaming: streams the ARC-MOF tarball (ARCMOF_20241004.tar.gz, ~670 MB) and extracts only the requested CIFs — the stream is read once but only matching files are written to disk

Subsequent runs with the same --output-dir skip already-downloaded CIFs.

Examples

Example 1: Query Zn MOFs from QMOF for CO₂ screening pre-processing

# Env: base-agent
MP_API_KEY=<your_mp_api_key> \
python .agents/skills/chem-db-mof/scripts/query_mof_db.py \
    --database qmof \
    --formula Zn \
    --max-results 10 \
    --output-dir ./research/2026-03-27_test/qmof_zn

Example 2: Query Zn, Ni, or Mg hypothetical MOFs from ARC-MOF DB7

# Env: base-agent
# Zn-based
python .agents/skills/chem-db-mof/scripts/query_mof_db.py \
    --database arcmof-majumdar \
    --elements Zn,O,C \
    --max-results 50 \
    --output-dir ./research/2026-03-27_arcmof_zn

# Ni-based
python .agents/skills/chem-db-mof/scripts/query_mof_db.py \
    --database arcmof-majumdar \
    --elements Ni,O,C \
    --max-results 50 \
    --output-dir ./research/2026-03-27_arcmof_ni

# Mg-based
python .agents/skills/chem-db-mof/scripts/query_mof_db.py \
    --database arcmof-majumdar \
    --elements Mg,O,C \
    --max-results 50 \
    --output-dir ./research/2026-03-27_arcmof_mg

Tip: You can expand diversity by adding more elements to --elements (e.g., Zn,Ni,O,C,N to retrieve MOFs containing all of those elements simultaneously), or run separate queries per metal node and combine the resulting CIF directories for a broader screening campaign.

Constraints

API limits: QMOF via MPContribs has rate limits; keep --max-results ≤ 100 per call.
ARC-MOF first-run time: Downloading the metadata CSV (~110 MB) takes ~1–2 min; streaming the tarball for CIF extraction adds ~5–15 min depending on how many structures are requested and network speed.
ARC-MOF CIF fallback: If some DB7 structures are not found in ARCMOF_20241004.tar.gz, they may reside in all_structures_1.tar.gz or all_structures_2.tar.gz. Update ARCMOF_STRUCTURES_NAME in the script if needed.
Element filtering (ARC-MOF): Requires a formula or chemical_formula column in geometric_properties.csv. If the column is absent, all DB7 entries are returned without element filtering.
Post-download: Structures from ARC-MOF DB7 include REPEAT partial charges embedded in the CIF. These can be used directly for classical force-field simulations but should be relaxed with an MLIP before running Widom insertion (see chem-sorption-relax).

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

License: MIT

Dependency or permission surface needs review
Permission surface may require sandboxing
The script excerpt is truncated, so full code review is not possible; however, no obvious security red flags are present in the visible portion.
The skill does not mention checksum verification for downloaded files (e.g., geometric_properties.csv, tarball), which could be a supply-chain risk.
The distinction between ARC-MOF DB7 and the Majumdar subset is slightly confusing; the skill references both Zenodo and Materials Cloud sources without fully clarifying the relationship.
