Moli is a Rust-based headless browser that gives AI agents a complete browser runtime for retrieving pages, extracting content, searching the web, and automating browser tasks. It is for agents and developers who need JavaScript, DOM, CSS, networking, storage, rendering, screenshots, or browser automation through CLI, CDP, or WebDriver protocols. The catalogue contains skills and instructions for using Moli.
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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Tool Misuse · line 21 Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.
- low Supply Chain · line 20 Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
What it costs to keep this loaded
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 | $0.00090 | $0.01372 |
| Opus 5.5 | $0.00036 | $0.00549 |
| Sonnet 5.5 | $0.00018 | $0.00274 |
| Haiku 4.5 | $0.00009 | $0.00137 |
Grade A, and why
moli-webfetch scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl --proto '=https' --tlsv1.2 -fsSL \ How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Fetch Websites with Moli
Use Moli's one-shot fetch command to read or capture websites. Moli executes
JavaScript and maintains the live DOM by default. Keep ordinary text retrieval
structure-first; enable layout only when the result needs pixels or pagination.
Workflow
-
Resolve
molifromPATH. If it is unavailable, install the latest prebuilt release for the current platform:Linux or macOS:
curl --proto '=https' --tlsv1.2 -fsSL \ https://github.com/lexmount/moli/releases/latest/download/moli-installer.sh | shOn Windows, use PowerShell:
powershell -ExecutionPolicy ByPass -c "irm https://github.com/lexmount/moli/releases/latest/download/moli-installer.ps1 | iex"Resolve the installed binary again and run
moli --version. The default location is~/.local/bin/molion Linux/macOS and%LOCALAPPDATA%\Moli\bin\moli.exeon Windows when it is not yet onPATH. -
Fetch the seed URL as Markdown with the default completion strategy:
moli fetch --dump markdown --wait-until done "https://example.com" -
Check the exit status and verify that stdout contains the requested page content. Keep stderr available for diagnostics; do not mix log output into the extracted content.
-
For dynamically rendered pages, choose the completion signal that matches the site:
- Use
--wait-until networkidlewhen relevant data loading finishes after network activity becomes quiet. - Use
--wait-until domstablewhen content is ready after DOM mutations settle. Avoidnetworkidleon long-polling or streaming pages, and avoiddomstablewhen the page continuously mutates timers, counters, or animations.
moli fetch --dump markdown --wait-until networkidle "https://example.com/app" moli fetch --dump markdown --wait-until domstable "https://example.com/feed" - Use
-
If important client-rendered content is still absent, select a page-specific readiness signal. Prefer a stable content selector over a fixed delay:
What ships with it
2 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.

moli-webfetch is a skill published in the GitHub repository lexmount/moli (19,470 stars, last pushed today), licensed Apache-2.0. It adds 90 tokens to every session and 1,372 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
