What is xugu-mcp CLAUDE.md?

A project instruction file for an MCP server that connects Python applications to XuguDB, a Chinese database system. It documents the project layout, Python version, dependency commands, and ways to run the server.

Use it when developing, installing, running, or inspecting this XuguDB database connector and its MCP server.

It gives a coding agent the project context and common commands needed to work on the repository consistently.

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	$0.00978	$0.00978
Opus 5	$0.00489	$0.00489
Sonnet 5	$0.00196	$0.00196
Haiku 4.5	$0.00098	$0.00098

Security

Grade A, and why

xugu-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 10d 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.

Python Version: 3.12 (see .python-version)
Package Manager: uv (fast Python package manager)
Project Type: MCP server using the mcp[cli] package

Common Commands

# Install dependencies
uv sync

# Run the project
uv run python main.py

# Run the MCP server
mcp dev .

XuguDB Driver Architecture

The xgcondb package provides cross-platform support with automatic platform detection:

Platform-Specific Drivers

Directory	Platform	Architecture	Files
`xgcondb-win/`	Windows	x86_64	`.pyd` DLLs
`xgcondb-mac/`	macOS (Darwin)	Universal	`.so` binaries
`xgcondb-linux-64/`	Linux	x86_64	`.so` binaries
`xgcondb-linux-arm64/`	Linux	ARM64	`.so` binaries

Platform Adapter

The xgcondb/__init__.py automatically:

Detects the operating system and architecture
Loads the appropriate platform-specific driver
Exports a unified API (connect(), Connection, etc.)

Supported Platforms:

Windows (x86_64)
macOS (Darwin, universal)
Linux (x86_64 and ARM64)

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.
