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 | $0.06169 | $0.06169 |
| Opus 5 | $0.03085 | $0.03085 |
| Sonnet 5 | $0.01234 | $0.01234 |
| Haiku 4.5 | $0.00617 | $0.00617 |
Grade A, and why
ifc-ids-mcp 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 12d 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.

IDS MCP Server - AI Agent Guide
For: Claude, GPT, and other AI agents working on this project Last Updated: 2025-11-02 Project Status: ✅ Implementation Complete - Fully Functional with Early Validation
Quick Start
This project is an MCP (Model Context Protocol) server that enables AI agents to create buildingSMART IDS (Information Delivery Specification) files that are 100% compliant with the IDS 1.0 standard.
What you need to know:
- ✅ Design complete - Full specification documented
- ✅ PRDs complete - 9 implementation phases planned
- ✅ Implementation complete - Following TDD methodology with early validation
- 🎯 Goal: 100% IDS 1.0 XSD compliance using IfcTester library ✅ ACHIEVED
Project Overview
What is IDS?
Information Delivery Specification (IDS) is a buildingSMART standard for:
- Defining what information is required in BIM models
- Automatically checking IFC models for compliance
- Standardizing requirements across different BIM software tools
What Does This Server Do?
This MCP server provides AI agents with tools to:
- Create IDS documents programmatically
- Load existing IDS files
- Add specifications with applicability and requirements
- Add facets (Entity, Property, Attribute, Classification, Material, PartOf)
- Add restrictions (enumeration, pattern, bounds, length)
- Validate IDS documents and IFC models
- Export to standards-compliant XML
- Early validation - Catch IDS 1.0 constraint violations before XML generation
Essential Reading (In Order)
1. Project Constitution 📜
File: constitution.md
Read this FIRST. Contains the 6 non-negotiable principles:
- 100% IDS Schema Compliance
- Test-Driven Development (95%+ coverage)
- IfcTester Integration First
- Deterministic Generation
- FastMCP Context-Based Session Management
- Python Best Practices
Key Takeaway: Every decision must align with these principles.
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.

ifc-ids-mcp CLAUDE.md is an instructions file published in the GitHub repository vinnividivicci/ifc-ids-mcp (27 stars, last pushed 5mo ago), licensed MIT. It adds 6,169 tokens to every session, about $0.0308 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 2026-08-30.
