toolsnap

toolsnap is a skill for Claude Code, Codex from icosaedro-git/toolsnap-mcp. It costs 13 tokens per session (1,039 once invoked), scanned A, original, MIT.

A tool for extracting exact, repeatable information from web pages and documents. It can return selected data without placing an entire large page or file into the AI assistant's context.

In plain words
What is it for?
Use it to quote pages, turn tables and files into structured data, inspect PDFs, RSS feeds, sitemaps, and SEO metadata, or estimate a document's token cost.
Why use it?
It reduces errors from summaries and avoids loading more document content than needed. It does not search the web or operate interactive browser pages.

Token cost

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.

Security

Grade A, and why

toolsnap 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ToolSnap Skill

Extract exact, reproducible data from web pages and documents through the ToolSnap MCP server, which parses server-side and returns only the answer — large pages never enter the context window. It does not search the web and does not drive a browser; discovery and interaction stay with native tools.

When to Use

  • Quoting or citing a page exactly, where an LLM summary could drift
  • Turning HTML tables, CSV/JSON files, PDFs, RSS feeds, or sitemaps into structured data
  • Querying a large dataset for a few rows instead of loading the whole file
  • Auditing SEO metadata (title/canonical/og:*, JSON-LD) as data
  • Checking token cost of a document before ingesting it

Keep native web_search for discovery (ToolSnap does not search) and browser_navigate for JS-heavy SPAs, logins, and page interaction.

Prerequisites

The toolsnap MCP server, installed from the catalog:

hermes mcp install official/toolsnap

It is a remote server on Cloudflare Workers (streamable HTTP) — nothing runs locally and the free tools need no account, API key, or configuration.

How to Run

Call the MCP tools directly. Only a curated core appears in tools/list; the rest of the catalog is reachable through two meta-tools:

  1. tool_catalog() — families overview; tool_catalog(family="...") or tool_catalog(tool="...") returns a tool's schema.
  2. use_tool(name="...", args={...}) — execute any cataloged tool, same behavior as a direct call.
  3. task_recipes() — ready multi-tool plans (clone a site, SEO audit, …).

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.
