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 | $0.00660 | $0.00660 |
| Opus 5 | $0.00330 | $0.00330 |
| Sonnet 5 | $0.00132 | $0.00132 |
| Haiku 4.5 | $0.00066 | $0.00066 |
Grade A, and why
scc-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 7d 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
The opening of the file, as written. The whole thing — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
What this is
MCP (Model Context Protocol) server that exposes boyter/scc
(a code-counting / complexity tool) to an LLM. Python project managed with uv.
Current state
uv project (Python 3.14). Dep: fastmcp (standalone v2); dev dep: pytest.
Server exposes 7 read-only scc tools (see REQUIREMENTS.md). Registered as a
local MCP in opencode.json via uv run scc-mcp.
Layout
scc_mcp/main.py—FastMCPinstance +main(); imports each tool module and calls itsregister(mcp).scc_mcp/runner.py— scc location, path safety, subprocess invocation (find_scc,validate_path,run_scc,run_scc_json,run_scc_no_path).scc_mcp/models.py—ResponseFormatenum +SccBaseInput(path, filters).scc_mcp/format.py—markdown_table+render(markdown default, JSON fallback).scc_mcp/tools/{summary,byfile,languages}.py— tool defs grouped by scc backend (json2 / json --by-file / --languages). Each exposesregister(mcp).
Commands
- Install deps:
uv sync - Add a dep:
uv add <pkg>/ dev dep:uv add --dev <pkg>(don't hand-edit deps) - Run server (stdio):
uv run scc-mcp - Run tests:
uv run pytest - Build artifacts:
make build
Conventions / gotchas
- Import is
from fastmcp import FastMCP(standalone v2), NOT the official SDK'sfrom mcp.server.fastmcp import FastMCP. The two APIs differ; follow fastmcp v2 docs. - Pydantic input models passed to
@mcp.toolmust be module-level, not defined inside a closure — FastMCP resolves type hints against module globals and will raiseNameErrorotherwise. sccis an external binary, not a Python dependency. Assume it is installed and onPATH— do NOT install it. Invocations must fail clearly if it is missing.- Only scan paths with read + execute access (
os.access(p, os.R_OK | os.X_OK)); default to the current working directory. - Tests that shell out to scc are guarded by the
requires_sccskip marker intests/conftest.py; thesample_treefixture builds a tmp multi-language project. - Useful
sccmachine-readable output:--format json2(project summary + COCOMO),--format json --by-file(per-file stats incl. complexity),--languages(no path).
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.

scc-mcp AGENTS.md is an instructions file published in the GitHub repository NicholasSynovic/scc-mcp (0 stars, last pushed 1mo ago), licensed BSD-3-Clause. It adds 660 tokens to every session, about $0.0033 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.
