highs-mcp CLAUDE.md is an instructions file for Claude Code from wspringer/highs-mcp. It costs 395 tokens per session, scanned A, original, MIT.

A project instruction file for an MCP server that gives language models access to HiGHS, software for solving mathematical optimization problems.

In plain words
What is it for?
Use it when developing the server, adding optimization tools such as sparse-matrix support, or documenting changes for the project.
Why use it?
It explains the repository's change-file rules, including how to record feature, patch, and breaking changes for releases.

Instructions file for Claude Code

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

This is wspringer/highs-mcp's own configuration. It tells Claude Code how to work on highs-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 highs-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

highs-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.

What it actually says

Project Overview

This is an MCP server offering HiGHS optimization tools to LLMs.

Knope

In this project, we're keeping track of changes using Knope. Claude itself is not capable of using the knope tool, so whenever we want Claude to define a changeset, it needs to build it by hand. Here are some of the rules to take into account:

  • Changeset files live in the .changeset directory.

  • Changeset files must have a unique name.

  • Typically the name of the file is snake-cased, lower characters, with a .md suffix.

  • Knope typically generates a file that is based on the first readable line in the body description of the changeset, abbreviating it, lowercasing it all and snake-casing it. It wouldn't hurt to maintain that convention.

  • The body of the markdown file typically starts with a one line summary of the change, formatted as a title.

    # Add support for version 3.0 of jquery
    
  • The frontmatter should look like this:

    ---
    default: major|minor|patch
    ---
    
  • The specific type: 'major', 'minor', or 'patch' should be based on an assesment of the character of the changes that are documented in that changeset.

    • Breaking changes: 'major'
    • Feature enhancements: 'minor'
    • Bug fixes and alike: 'patch'

Feature example

---
default: minor
---

# Add sparse matrix support

Implemented COO format sparse matrix handling for improved memory efficiency
with large optimization problems.

Breaking change example

---
default: major
---

# Restructure MCP server API endpoints

Renamed optimization endpoints and changed request/response format
for better consistency with MCP standards.
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.
