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

mcp-kanka 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 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in the mcp-kanka repository.

Project Overview

This is an MCP (Model Context Protocol) server that provides AI assistants with tools to interact with Kanka campaigns. It exposes 9 tools for CRUD operations on Kanka entities (characters, locations, organizations, etc.) and implements client-side filtering, fuzzy search, and markdown/HTML conversion.

Key Development Commands

This project uses uv for dependency management. All commands are wrapped in the Makefile for convenience:

# Install development environment (uses uv sync)
make install

# Sync dependencies without updating lock file
make sync

# Run tests
make test

# Format code
make format

# Run linting
make lint

# Run type checking
make typecheck

# Run everything (lint + typecheck + tests)
make check

# Generate coverage report
make coverage

# Clean up generated files
make clean

Direct uv commands

# Install dependencies
uv sync --all-groups

# Run a command in the environment
uv run pytest

# Add a new dependency
uv add package-name

# Add a dev dependency
uv add --group dev package-name

# Update dependencies
uv lock --upgrade

# Build the package
uv build

Git Commit Message Format

This project uses conventional commits format:

<type>(<scope>): <subject>

<body>

<footer>

Types:

  • feat: New feature
  • fix: Bug fix
  • docs: Documentation only changes
  • style: Code style changes (formatting, missing semicolons, etc)
  • refactor: Code change that neither fixes a bug nor adds a feature
  • test: Adding missing tests or correcting existing tests
  • chore: Changes to build process, dependencies, or auxiliary tools

Examples:

  • feat: add sync/timestamp features and change name filtering
  • fix: correct pagination logic to use SDK properties
  • chore(deps): update dependency python to v3.13.5
  • refactor: add operations layer for reusable business logic

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.
