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 5.1 | $0.00012 | $0.00402 |
| Opus 5.5 | $0.00005 | $0.00161 |
| Sonnet 5.5 | $0.00002 | $0.00080 |
| Haiku 4.5 | $0.00001 | $0.00040 |
Grade A, and why
modify-model 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 1mo 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.
What it actually says
Modify, delete, or update elements in the Revit model based on user instructions.
Determine Action
Based on $ARGUMENTS:
"delete" / "remove":
- Identify elements to delete — by selection (
get_selected_elements), by filter (ai_element_filter), or by IDs - Confirm with the user before deleting (show count and types)
- Call
delete_elementswith the element IDs - Report deleted count and any cascaded deletions (hosted elements)
"modify" / "change" / "set" / "update":
- Identify the target element(s) — by selection, filter, or ID
- Identify which parameters to change and new values
- Call
modify_elementfor each element - Report old and new values for confirmation
"select" / "what's selected":
- Call
get_selected_elements - Present: ID, Category, Type, Level, Key Parameters
"find" / "filter":
- Call
ai_element_filterwith appropriate category and criteria - Present matching elements in a table
Rules
- Always confirm destructive operations (delete) before executing
- Report cascaded deletions (e.g., deleting a wall also removes hosted doors)
- When modifying, show old values alongside new values
- If element IDs are needed but not provided, help the user find them via selection or filtering
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.

modify-model is a command published in the GitHub repository Demolinator/revit-mcp-plugin (7 stars, last pushed 20d ago), licensed Apache-2.0. It adds 12 tokens to every session and 402 once invoked, about $0.0000 per session on Opus 5.5. 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.
