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 | $0.02147 | $0.02147 |
| Opus 5.5 | $0.00859 | $0.00859 |
| Sonnet 5.5 | $0.00429 | $0.00429 |
| Haiku 4.5 | $0.00215 | $0.00215 |
Grade A, and why
cf-mcp AGENTS.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 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.
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
CF::MCP is a Ruby gem that implements an MCP (Model Context Protocol) server for the Cute Framework, a C/C++ 2D game framework. It indexes header files, extracts documentation from comments, and provides search functionality for functions, structs, and enums.
Commands

# Run a single test file
ruby -Ilib:test test/cf/mcp/parser_test.rb
# Run a specific test method
ruby -Ilib:test test/cf/mcp/parser_test.rb --name test_parse_function_doc
# Lint code with Standard Ruby
rake standard
# Auto-fix linting issues
rake standard:fix
# Validate signatures, type check with Steep, run tests under the runtime type checker
rake rbs
# Run tests, lint, type check, and generate manifest (default task)
rake
# Start interactive console

CLI Usage
# STDIO mode (for Claude Desktop integration)
cf-mcp stdio --root ~/Work/GitHub/pusewicz/cute_framework
# HTTP mode (web UI at /, MCP endpoint at /http, port 9292)
cf-mcp http --port 9292 --root /path/to/cute_framework
# Download headers from GitHub automatically
cf-mcp stdio --download
# Cache the parsed docs (~/.cache/cf-mcp, one file per root); re-run to pick up changes
cf-mcp index --root ~/Work/GitHub/pusewicz/cute_framework
# Every MCP tool is also a command (flags after the command belong to the tool)
cf-mcp search sprite --type function --limit 5
cf-mcp get_details CF_Sprite
Tool commands are found through Tools.all, read the cache and rebuild it when the headers change. Each root has its own cache file, and a command that names none uses the last one. --help goes without the index. SearchTool and ListCategory read the index's categories in CategoryEnum when their schema is asked for, so tool classes can load before the index is filled; CLI#take_source_options pulls --root/--download out of a tool command's arguments first because its flags are checked against those categories.
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.

cf-mcp AGENTS.md is an instructions file published in the GitHub repository pusewicz/cf-mcp (2 stars, last pushed 4d ago), licensed MIT. It adds 2,147 tokens to every session, about $0.0086 per session on Opus 5.5. 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.
