Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00877 | $0.00877 |
| Opus 5 | $0.00439 | $0.00439 |
| Sonnet 5 | $0.00175 | $0.00175 |
| Haiku 4.5 | $0.00088 | $0.00088 |
Grade A, and why
darktable-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
dark-table-mcp
Goal: build an MCP server that lets AI agents drive darktable — the open-source (GPL) non-destructive RAW photo editor — for library queries, metadata edits, style application, and headless exports.
Research notes — read these first
All darktable research lives in the Obsidian vault, NOT in this repo:
C:\Users\CalebBennett\Documents\Notes\Caleb's Vault\Software\DarkTable\
Start at DarkTable MOC.md — it indexes ~100 atomized notes (one concept per note,
filenames like DarkTable - <Concept>.md). Most notes carry an "MCP relevance" line.
Note conventions (follow when adding findings)
Any NEW darktable finding made while working in this repo goes into that Notes folder, not into this repo's docs:
- One concept per note, filename
DarkTable - <Concept>.md - YAML frontmatter:
tags: [darktable, research],source: <url>,created: <date> - 3–10 sentence self-contained body, wikilinks to related notes,
[[DarkTable MOC]]at the bottom - Add an "MCP relevance" line when the concept affects MCP design
- Add the new note to
DarkTable MOC.mdunder the right section - Check for an existing note on the concept first — update it rather than duplicating
Key integration surfaces (details in the notes)
- Lua API (
[[DarkTable - Lua API Overview]], API v9.x): the primary automation surface — database, tags, styles, collection, export storage, events. - DBus
Remote.Lua([[DarkTable - Lua DBus Interface]]): send a Lua string to a live darktable session, get a string back — the leading MCP bridge candidate. Validated working on this machine (darktable 5.6.0, Lua API 9.7.0, Windows) — see[[DarkTable - DBus Validation (Local Install)]]. Use the bundledC:\Program Files\darktable\bin\gdbus.exe; the GUI must be running; Lua mustrequire 'darktable'(the global isn't preset); replies come back as a tuple('...',). Issue #17896 does NOT affect this build. darktable-cli([[DarkTable - darktable-cli]]): headless export/processing without a GUI.- Library database + XMP sidecars (
[[DarkTable - Library Database]],[[DarkTable - XMP Sidecar Files]]): library.db is SQLite but single-instance locked ([[DarkTable - Database Locking]]) and takes precedence over XMPs — never write to it while darktable runs; prefer the Lua/DBus path or XMP + startup sync. - Companion Lua script (
[[DarkTable - Lua Startup Scripts (luarc)]]): the MCP server will likely ship a Lua helper loaded via luarc/script manager.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

darktable-mcp CLAUDE.md is an instructions file published in the GitHub repository Caleb68864/darktable-mcp (1 stars, last pushed 2mo ago), licensed MIT. It adds 877 tokens to every session, about $0.0044 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
