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 | $0.00815 | $0.00815 |
| Opus 5 | $0.00407 | $0.00407 |
| Sonnet 5 | $0.00163 | $0.00163 |
| Haiku 4.5 | $0.00081 | $0.00081 |
Grade A, and why
powerbi-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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Documentation
Read DEVELOPER_GUIDE.md for comprehensive development guidance including module responsibilities, entry points, environment variable loading, and common development tasks.
Keep both README.md and DEVELOPER_GUIDE.md updated with any user-facing or architectural changes.
Architecture
Modular MCP server organized by separation of concerns (~2120 total LOC across 13 files):
powerbi_mcp/
├── __init__.py # Main entry point (contains main())
├── __main__.py # Module execution support
├── server.py # FastMCP initialization
├── auth.py # OAuth2 authentication, token management
├── client.py # PowerBI REST API client
├── constants.py # Configuration values (URLs, timeouts, limits)
├── exceptions.py # Centralized error handling
├── validation.py # Reusable input validation
├── formatters.py # Response formatting (markdown/JSON)
├── models.py # Pydantic data models
└── tools/ # MCP tool definitions
├── workspaces.py # Workspace operations
├── datasets.py # Dataset operations
└── queries.py # DAX query execution
Key principle: Configuration in constants.py, validation in validation.py, error handling in exceptions.py. One change updates all tools automatically.
Development Commands
# Package manager: uv (with .venv virtual environment)
uv sync # Install dependencies
uv run run-server # Run server (calls powerbi_mcp:main)
# Development testing with MCP Inspector
npx @modelcontextprotocol/inspector uv --directory . run run-server
Development Guidelines
-
File Size: Keep LOC per file ≤ 400 lines (current files comply).
-
Module Responsibilities: See DEVELOPER_GUIDE.md for what belongs where. Follow existing patterns.
-
File Creation: Do not create files/directories unnecessarily. Only create when explicitly required.
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.

powerbi-mcp CLAUDE.md is an instructions file published in the GitHub repository gurvinder-dhillon/powerbi-mcp (0 stars, last pushed 7mo ago), licensed MIT. It adds 815 tokens to every session, about $0.0041 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
