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 | $0.00815 | $0.00815 |
| Opus 5 | $0.00407 | $0.00407 |
| Sonnet 5 | $0.00163 | $0.00163 |
| Haiku 4.5 | $0.00081 | $0.00081 |
Grade A, and why
mdfmcp 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 8d 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

Project Overview
This is an MCP (Model Context Protocol) server for analyzing ASAM MDF (Measurement Data Format) files. It enables AI assistants to access and analyze automotive and industrial measurement data through a standardized interface.
Key Architecture
The main implementation is in src/mdfmcp/server.py:61 - the MdfMcpServer class that provides:
- Session Management: Multi-file support with timeout handling (
MdfSessiondataclass atsrc/mdfmcp/server.py:37) - Dynamic Tool Generation: Automatically exposes MDF methods as MCP tools (see
EXPOSE_METHODSatsrc/mdfmcp/server.py:65) - Special Handlers: Custom processing for complex return types (defined in
SPECIAL_HANDLERSatsrc/mdfmcp/server.py:73) - Data Analysis: Statistics, plotting, and export capabilities
The server exposes 20+ tools dynamically based on the asammdf library API, with special handling for methods that return complex objects like Signal or MDF instances.

Project Structure
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.

mdfmcp CLAUDE.md is an instructions file published in the GitHub repository Shanko-26/mdfmcp (4 stars, last pushed 1y ago), licensed MIT. It adds 815 tokens to every session, about $0.0041 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.
