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 | $0.00108 | $0.01379 |
| Opus 5 | $0.00054 | $0.00690 |
| Sonnet 5 | $0.00022 | $0.00276 |
| Haiku 4.5 | $0.00011 | $0.00138 |
Grade A, and why
webflow 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 6d 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Webflow 🪂
Read and edit Webflow sites through the official Webflow MCP server: pages, CMS, assets, components, styles, variables, custom code, comments, localization, and publishing.
Setup
This plugin ships the Webflow MCP server (.mcp.json → webflow, remote
HTTP at https://mcp.webflow.com/mcp). It registers automatically when the
plugin is enabled — no claude mcp add, no API key.
You only need to authenticate (OAuth) once:
- Call the
authenticatetool, open the returned URL, authorize. - The real tools load automatically once the flow completes. If the
localhost/callbackpage errors, pass the full address-bar URL tocomplete_authentication.
Verify with a real call before claiming success — e.g. data_sites_tool
→ list_sites. "Connected" in /mcp is not proof; run a tool.
Standalone (no plugin)? Add the server by hand:
claude mcp add webflow --transport http https://mcp.webflow.com/mcp.
Two tool tiers — read this first
| Tier | Tools | Needs Designer open? |
|---|---|---|
| Data API (REST) | data_sites_tool, data_pages_tool, data_cms_tool, data_assets_tool, data_scripts_tool, data_comments_tool, data_localization_tool |
No — works headless |
| Designer API (live canvas) | de_page_tool, de_component_tool, element_tool, element_builder, whtml_builder, style_tool, variable_tool, asset_tool, element_snapshot_tool |
Yes |
Designer tools require the Webflow Designer open in a browser tab, in the foreground, with the MCP Bridge app running. When the tab goes to the background or idle, calls time out / "Unable to connect" — the server returns a Bridge-app link; share it as a markdown link and ask the user to reopen the Designer and keep it foreground, then retry.
Always call webflow_guide_tool once at the start of a Designer session
(the server requires it before other tools). ask_webflow_ai answers
Webflow how-to questions.

Inventory / audit (headless)
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.

webflow is a skill published in the GitHub repository Yesterday-AI/skills (2 stars, last pushed 3d ago), licensed MIT. It adds 108 tokens to every session and 1,379 once invoked, about $0.0005 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.
