scicompute-mcp: Instructions file for Claude Code

CLAUDE.md

scicompute-mcp CLAUDE.md is an instructions file for Claude Code from sanshanjianke/scicompute-mcp. It costs 246 tokens per session, scanned A, original, Unlicense.

Instructions for SciCompute MCP, a server that lets AI coding assistants run scientific calculations through tools such as Mathematica, SageMath, Julia, Python, R, Octave, and MATLAB.

In plain words
What is it for?
Use them to run or stop computations and look up documentation for a selected scientific-computing backend.
Why use it?
They explain which calculation backends are available and how the project configures them.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is sanshanjianke/scicompute-mcp's own configuration. It tells Claude Code how to work on scicompute-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything scicompute-mcp configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

scicompute-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 10d 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.

What it actually says

SciCompute MCP Server

MCP server providing scientific computing capabilities for AI coding assistants.

Available Backends

Backend Use Case
mathematica Symbolic computation, numerical computing, plotting
sage Number theory, algebra, symbolic computation
julia High-performance numerical computing, plotting
py_scientific Python scientific computing (NumPy, SciPy, SymPy, Matplotlib)
r Statistical computing, data visualization
octave Numerical computing, plotting
matlab Numerical computing, visualization, matrix operations

Usage

Call via MCP tools:

  • mcp__scicompute__compute(code, backend) - Execute computation code
  • mcp__scicompute__stop(backend) - Stop backend process
  • mcp__scicompute__doc(symbol, backend) - Query documentation

Configuration

Backend paths are configured in src/scicompute_mcp/backends/*.py, can be overridden via environment variables:

  • SAGE_PATH - SageMath path
  • MATHEMATICA_KERNEL_PATH - Mathematica kernel path
  • MATLAB_PATH - MATLAB executable path
Changes

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.
