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 | $0.00866 | $0.00866 |
| Opus 5.5 | $0.00346 | $0.00346 |
| Sonnet 5.5 | $0.00173 | $0.00173 |
| Haiku 4.5 | $0.00087 | $0.00087 |
Grade A, and why
symkit-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 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.
How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Overview
SymKit MCP — A general-purpose symbolic formula derivation engine for AI agents.
Built on SymPy + FastMCP. Provides 47 MCP tools covering:
- A unified
math()tool for 32 symbolic operations (calculus, linear algebra, ODE, transforms) - Step-by-step derivation sessions with CRUD control
- Symbol assumption management
- External formula search (Wikidata, SciPy constants, BioModels)
- Result verification (symbolic equality, reverse operations, dimension analysis)
- Code/report generation (Python, LaTeX, Markdown, SymPy scripts)
SymKit is domain-agnostic: it supports physics, engineering, chemistry, biology, economics, and any field that uses mathematical formulas.

Usage Patterns
# Stateless quick calculation
math("diff", "x**3", variable="x") # → 3*x**2
# Stateful derivation
session_start("sho_oscillator", domain="mechanics")
math("dsolve", "m*diff(x(t),t,2) + k*x(t)", func="x", var="t", session=True)
session_show()
session_complete(description="Simple harmonic oscillator angular frequency")

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.

symkit-mcp CLAUDE.md is an instructions file published in the GitHub repository LBurny/symkit-mcp (13 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 866 tokens to every session, about $0.0035 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.
