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 | $0.06113 | $0.06113 |
| Opus 5 | $0.03057 | $0.03057 |
| Sonnet 5 | $0.01223 | $0.01223 |
| Haiku 4.5 | $0.00611 | $0.00611 |
Grade A, and why
ckan-mcp-server CLAUDE.md 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 today.
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.

The opening of the file, as written. The whole thing — 521 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenSpec Instructions
These instructions are for AI assistants working in this project.
Always open @/openspec/AGENTS.md when the request:
- Mentions planning or proposals (words like proposal, spec, change, plan)
- Introduces new capabilities, breaking changes, architecture shifts, or big performance/security work
- Sounds ambiguous and you need the authoritative spec before coding
Use @/openspec/AGENTS.md to learn:
- How to create and apply change proposals
- Spec format and conventions
- Project structure and guidelines
Keep this managed block so 'openspec update' can refresh the instructions.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Important: This project uses English as its primary language. All documentation, code comments, and commit messages should be in English. This includes LOG.md, tasks/, issues and pull request descriptions — no exceptions.
Project Overview
CKAN MCP Server - MCP (Model Context Protocol) server for interacting with CKAN-based open data portals (dati.gov.it, data.gov, demo.ckan.org, etc.).
The server exposes MCP tools for:
- Advanced dataset search with Solr syntax
- DataStore queries for tabular data analysis
- Organization and group exploration
- Complete metadata access
Build and Development
Main Commands
# Build project (uses esbuild - fast and lightweight)
npm run build
# Run test suite (191 tests - unit + integration)
npm test
# Watch mode for tests during development
npm run test:watch
# Test coverage report
npm run test:coverage
# Start server in stdio mode (default for local integration)
npm start
# Start server in HTTP mode (for remote access)
# HTTP requires a domain allowlist (or CKAN_HTTP_ALLOW_ALL=true to opt out)
CKAN_ALLOWED_DOMAINS="www.dati.gov.it" TRANSPORT=http PORT=3000 npm start
# Watch mode for development
npm run watch
# Build + run
npm run dev
# Cloudflare Workers deployment (v0.4.0+)
npm run build:worker # Build for Workers
npm run dev:worker # Test locally with Wrangler
npm run deploy # Deploy to Cloudflare Workers
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.

ckan-mcp-server CLAUDE.md is an instructions file published in the GitHub repository ondata/ckan-mcp-server (57 stars, last pushed today), licensed MIT. It adds 6,113 tokens to every session, about $0.0306 per session on Opus 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.
