What is dataproc-mcp CLAUDE.md?

A set of development instructions for building and testing the dataproc-mcp-server project. It documents dependency installation, running the server, communication methods, debugging, and testing commands.

Use it when installing dependencies, running the server through standard input, HTTP, or server-sent events, enabling debug logs, or running tests and checks.

It gives contributors one reference for the project’s setup and operating commands, reducing guesswork when developing the server.

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	$0.00595	$0.00595
Opus 5.5	$0.00238	$0.00238
Sonnet 5.5	$0.00119	$0.00119
Haiku 4.5	$0.00060	$0.00060

Security

Grade A, and why

dataproc-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 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.

Dataproc MCP Server Development Guide

Build & Test Commands

Using uv (recommended)

Install dependencies: uv pip install --system -e .
Install dev dependencies: uv pip install --system -e ".[dev]"
Update lock file: uv pip compile --system pyproject.toml -o uv.lock
Install from lock file: uv pip sync --system uv.lock

Using pip (alternative)

Install dependencies: pip install -e .
Install dev dependencies: pip install -e ".[dev]"

Running the server

Run server (stdio): python -m dataproc_mcp_server
Run server with HTTP transport: DATAPROC_MCP_TRANSPORT=http python -m dataproc_mcp_server
Run server with SSE transport: DATAPROC_MCP_TRANSPORT=sse python -m dataproc_mcp_server
Run with MCP CLI: mcp run src/dataproc_mcp_server/server.py
Run with debug logging: DATAPROC_MCP_DEBUG=true python -m dataproc_mcp_server

Transport Configuration

STDIO (default): Standard input/output communication for command-line tools
HTTP: REST API over HTTP using streamable-http transport
SSE: Server-Sent Events for real-time communication
Set host/port: DATAPROC_MCP_HOST=0.0.0.0 DATAPROC_MCP_PORT=8080

Testing and linting

Run tests: pytest
Run single test: pytest tests/path/to/test_file.py::test_function_name -v
Run tests with coverage: python -m pytest --cov=src/dataproc_mcp_server tests/
Run linter: ruff check src/ tests/
Format code: ruff format src/ tests/

Technical Stack

Python version: Python 3.13+
Project config: pyproject.toml for configuration and dependency management
Environment: Use virtual environment in .venv for dependency isolation
Package management: Use uv for faster, more reliable dependency management with lock file
Dependencies: Separate production and dev dependencies in pyproject.toml
Version management: Use setuptools_scm for automatic versioning from Git tags
Linting: ruff for style and error checking
Type checking: Use VS Code with Pylance for static type checking
Project layout: Organize code with src/ layout

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.
