Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01953 | $0.01953 |
| Opus 5 | $0.00977 | $0.00977 |
| Sonnet 5 | $0.00391 | $0.00391 |
| Haiku 4.5 | $0.00195 | $0.00195 |
Grade B, and why
mkdocs-mcp-example CLAUDE.md scanned grade B with 1 finding 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 2d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Project Overview
This is a monorepo demonstrating the integration of MkDocs Material documentation with a Model Context Protocol (MCP) server. The project uses uv for dependency management and follows a workspace architecture with two main components.
Architecture
Workspace Structure
- Root: uv workspace configuration (
pyproject.toml) with shared development tools (ruff, mypy, pytest, pre-commit) - mkdocs-site/: MkDocs Material configuration (
mkdocs.yml) and theme customization - mcp-server/: Python MCP server implementation providing AI access to documentation
- docs/: Shared documentation source files consumed by both components
Core Components
MCP Server (mcp-server/src/mkdocs_mcp/):
server.py: Main MCP server using STDIO transport, handles protocol implementationresources.py: DocumentationResourceManager - converts Markdown files to MCP resources with frontmatter parsingtools.py: DocumentationToolManager - provides 5 AI tools: search_docs, find_by_title, list_pages, get_page_outline, search_code_blocks
MkDocs Configuration (mkdocs-site/mkdocs.yml):
- Material theme with dark/light mode, navigation features, and search
- Plugins: search, minify, git-revision-date-localized, mkdocstrings (for API docs)
- Markdown extensions: admonitions, code highlighting, Mermaid diagrams, tabbed content
docs_dir: ../docspoints to shared documentation source
Key Architectural Decision: The MCP server reads directly from the docs/ directory to serve real-time documentation content to AI assistants via the Model Context Protocol. MkDocs builds from the same docs/ directory, ensuring both systems stay synchronized.
Common Development Commands
Essential Setup
# Initial setup (runs uv sync --dev + pre-commit install)
make setup
# Start both documentation and MCP server simultaneously
make dev
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.
