What is mcp-harmony-context CLAUDE.md?

A set of project instructions for an AI coding assistant working on an MCP server. MCP, or Model Context Protocol, is a way for AI assistants to use tools and information from other systems; this server connects to Toon Boom Harmony help files.

Use it when developing, configuring, or running this Python-based server and connecting it to a local Toon Boom Harmony help folder.

It gives the assistant the project’s purpose, required software, setup steps, and configuration details instead of leaving those choices unclear.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00558	$0.00558
Opus 5.5	$0.00223	$0.00223
Sonnet 5.5	$0.00112	$0.00112

Security

Grade A, and why

mcp-harmony-context 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 2mo 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

This is an MCP (Model Context Protocol) server that provides context about Harmony and their API. The server is built using FastMCP and exposes resources and tools to help AI assistants understand and interact with Harmony's ecosystem.

Technology Stack

Python 3.12+: Required Python version
FastMCP: Framework for building MCP servers (mcp[cli]>=1.18.0)
uv: Package manager for Python dependencies

Configuration

The server requires configuration to point to the Harmony help documentation folder.

Environment Variable

Set the HARMONY_HELP_PATH environment variable to your Harmony installation help folder:

# Windows example
set HARMONY_HELP_PATH=C:\Program Files (x86)\Toon Boom Animation\Toon Boom Harmony 25 Essentials\help

# Or use .env file (copy .env.example to .env and modify)

The default path is: C:\Program Files (x86)\Toon Boom Animation\Toon Boom Harmony 25 Essentials\help

Development Commands

Setup and Installation

# Install dependencies using uv
uv sync

# Configure your Harmony help path (optional if using default)
# Copy .env.example to .env and update HARMONY_HELP_PATH

# Run the MCP server
uv run main.py

Testing the Server

# Use MCP inspector to test the server interactively
mcp dev main.py

Architecture

Core Structure

main.py: Entry point containing the FastMCP server instance and all resource/tool definitions
The server is registered as "mcp-harmony-context"

MCP Server Pattern

This project follows the FastMCP pattern:

@mcp.resource(): Decorator for defining resources that clients can fetch
@mcp.tool(): Decorator for defining tools that clients can invoke
Resources use URI templates (e.g., resource://pattern/{param})

Current Implementation

Configuration: HARMONY_HELP_PATH environment variable defines the path to Harmony help documentation
Resource harmony://config/help-path: Returns the configured help path and whether it exists
The server reads from the local Harmony help documentation folder to provide context

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.
