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 | $0.00080 | $0.10056 |
| Opus 5 | $0.00040 | $0.05028 |
| Sonnet 5 | $0.00016 | $0.02011 |
| Haiku 4.5 | $0.00008 | $0.01006 |
Grade B, and why
notte-browser scanned grade B with 2 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.
Instruction-override phrasingmediumPrompt injection
Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.
`notte page scrape --session-id <session-id>` ingests content from arbitrary URLs. That content reaches the calling agent's context as tool output and can contain prompt-injection attempts ("ignore previous instructions, Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Notte Browser CLI Skill
Command-line interface for launching and controlling Notte cloud browser sessions, scraping pages, managing browser credentials, and deploying reusable browser workflows as Notte Functions. A Function is the deployment form of a tested browser task: it can be invoked later as an HTTP API endpoint, run from the CLI/SDK, or scheduled.
General Documentation
For broader Notte concepts, current docs, and internet-search entry points, start with the documentation index:
https://docs.notte.cc/llms.txt
CLI vs. the bundled MCP servers
The notte plugin also ships two hosted MCP servers. Prefer the CLI for everything in this skill - it is the interface these instructions are written against. Reach for the MCP servers only in the cases below:
| Server | URL | What it is | When to use it |
|---|---|---|---|
notte-browser |
https://api.notte.cc/mcp |
The Notte browser API over MCP | Only when the client cannot run shell commands. Otherwise the CLI is more direct and better documented. |
anything-api |
https://anything.notte.cc/mcp |
Marketplace of ready-made Notte Functions, plus natural-language build |
Before building a new Function, call its search tool - someone may already have published one for the target site. |
anything-api exposes search (browse the marketplace, no auth), spec (get a function's variable schema), run, and build (natural language -> a new deployed Function, 2-10 minutes). build and run need authentication - OAuth via your client, or Authorization: Bearer $NOTTE_API_KEY. Browse it visually at https://anything.notte.cc/marketplace.
Both servers authenticate independently of notte auth login; a working CLI session does not imply a working MCP connection, and vice versa.
Setup
Use this skill after the notte CLI is installed. It assumes CLI v0.0.41 or newer. v0.0.30 renamed the list filter flags (--include-deleted, -a/--all, --running) and made notte functions runs return the full history by default; v0.0.31 adds --no-solve-captchas; v0.0.33 adds named --vault-field credential fills; v0.0.41 makes file upload, listing, and download session-scoped and addresses files by immutable ID. Check with notte version and upgrade if it is older; the commands below will not all work otherwise.
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

notte-browser is a skill published in the GitHub repository nottelabs/notte-skills (11 stars, last pushed 5d ago), licensed MIT. It adds 80 tokens to every session and 10,056 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 2 findings (instruction-override phrasing, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
