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 | $0.03246 | $0.03246 |
| Opus 5.5 | $0.01298 | $0.01298 |
| Sonnet 5.5 | $0.00649 | $0.00649 |
| Haiku 4.5 | $0.00325 | $0.00325 |
Grade C, and why
stm32 CLAUDE.md scanned grade C with 2 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

STM32 MCP Documentation Server - Claude Code Project
This file provides instructions for Claude Code when working with this project.
Project Overview
The STM32 MCP Documentation Server is an MCP (Model Context Protocol) server that provides semantic search over 80+ STM32 microcontroller documentation files. It includes 16 specialized agents and auto-installs everything on first run.
Key Features:
- Hybrid Search - Combines BM25 keyword matching with vector semantic search using Reciprocal Rank Fusion (RRF)
- Query Expansion - Automatic synonym expansion for STM32-specific terminology (e.g., "UART" expands to include "USART", "serial")
- Claude Haiku Re-ranking - LLM-based result re-ranking via Claude Code headless mode for improved relevance
- nomic-embed-text-v1.5 - High-quality 768-dimension embeddings with Matryoshka representation support
Repository: https://github.com/creativec09/stm32 (private)
Installation
One-Command Install (Recommended)
This installation method auto-installs uv if needed, making it work out-of-the-box on Ubuntu 24 WSL and other Linux systems:
# Install MCP server with auto-setup (auto-installs uv if needed, agents + docs auto-install on first run)
claude mcp add-json stm32-docs --scope user '{"command":"bash","args":["-c","export PATH=\"$HOME/.local/bin:$PATH\" && (command -v uvx >/dev/null 2>&1 || curl -LsSf https://astral.sh/uv/install.sh | sh -s -- -q) && uvx --from git+https://github.com/creativec09/stm32.git stm32-mcp-docs"]}'
Note: For private repository access, include a GitHub Personal Access Token in the URL:
claude mcp add-json stm32-docs --scope user '{"command":"bash","args":["-c","export PATH=\"$HOME/.local/bin:$PATH\" && (command -v uvx >/dev/null 2>&1 || curl -LsSf https://astral.sh/uv/install.sh | sh -s -- -q) && uvx --from git+https://[email protected]/creativec09/stm32.git stm32-mcp-docs"]}'
If you already have uv installed
claude mcp add stm32-docs --scope user -- uvx --from git+https://github.com/creativec09/stm32.git stm32-mcp-docs
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.

stm32 CLAUDE.md is an instructions file published in the GitHub repository creativec09/stm32 (11 stars, last pushed 7mo ago), licensed MIT. It adds 3,246 tokens to every session, about $0.0130 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
