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 | $0.00571 | $0.00571 |
| Opus 5 | $0.00285 | $0.00285 |
| Sonnet 5 | $0.00114 | $0.00114 |
| Haiku 4.5 | $0.00057 | $0.00057 |
Grade A, and why
handsontable-mcp-server CLAUDE.md 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.

Project Overview
A Model Context Protocol (MCP) server that provides access to Handsontable documentation for code generation. The server fetches documentation from handsontable.com, converts HTML to Markdown, and exposes it via MCP tools.
Architecture
Core Components
MCP Server (index.js)
- Built on
@modelcontextprotocol/sdk - Communicates via stdio transport
- Implements 3 tools:
get_doc,search_docs,list_categories - Uses JSDOM for HTML parsing and Turndown for Markdown conversion
- Simple in-memory cache with 1-hour TTL
Documentation Data
docs-structure.json- Pre-analyzed structure of 563 documentation pagessidebar.js- Original navigation structure from Handsontable docssitemap.xml- Complete site map with all URLsanalyze-docs.js- One-time script to extract documentation structure
Documentation Coverage
- 61 API endpoints (Core, Plugins, Hooks, etc.)
- 128 guide topics (Features, Integration, Migration)
- 20 categories organized by functionality
- 3 frameworks (JavaScript, React, Angular)
- Vue 2 & 3 integration guides
Development Commands
npm install # Install dependencies
npm start # Run MCP server
npm run dev # Run with auto-reload
node analyze-docs.js # Re-analyze documentation structure
Key Functions
fetchAndConvertDoc(url) - Fetches HTML, extracts main content, converts to Markdown
buildDocUrl(framework, path, isApi) - Constructs full URL from framework and topic
searchTopics(keyword) - Searches across API endpoints, guides, and categories
MCP Tools
-
get_doc - Fetch specific documentation page as Markdown
- Parameters: topic (required), framework (optional), type (optional)
-
search_docs - Search for topics by keyword
- Parameters: keyword (required)
-
list_categories - List all documentation categories
- Parameters: none
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.

handsontable-mcp-server CLAUDE.md is an instructions file published in the GitHub repository GreenFlux/handsontable-mcp-server (3 stars, last pushed 9mo ago), licensed MIT. It adds 571 tokens to every session, about $0.0029 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.
