What is osdu-mcp-server copilot-instructions.md?

Contributor instructions for an OSDU MCP server, a Python service that lets AI assistants use OSDU platform features such as partitions, legal tags, schemas, and storage records.

Use them when setting up the project or preparing changes, including running its dependency setup, tests, type checks, formatter, and linter.

They define the checks required before commits so code is formatted, tested, type-checked, and linted 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	$0.01042	$0.01042
Opus 5	$0.00521	$0.00521
Sonnet 5	$0.00208	$0.00208
Haiku 4.5	$0.00104	$0.00104

Security

Grade A, and why

osdu-mcp-server copilot-instructions.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.

GitHub Copilot Instructions for OSDU MCP Server

This is a Python-based Model Context Protocol (MCP) server that provides AI assistants with access to OSDU platform capabilities. The project follows an AI-driven development workflow with strict architectural patterns.

Project Overview

OSDU MCP Server enables AI assistants to interact with the Open Subsurface Data Universe (OSDU) platform. It provides tools for managing partitions, legal tags, schemas, and storage records with built-in safety features.

Code Standards

Required Before Each Commit

Run these commands to ensure code quality:

uv run mypy .           # Type checking (must pass)
uv run flake8 src/      # Linting (must pass)
uv run black src/ tests/ # Format code
uv run pytest           # All tests must pass (80% coverage minimum)

Development Flow

Setup: uv sync && uv pip install -e .[dev]
Test: uv run pytest
Type check: uv run mypy .
Format: uv run black src/ tests/
Full check: uv run mypy . && uv run flake8 src/ && uv run pytest

Repository Structure

src/osdu_mcp_server/: Main package
- shared/: Core infrastructure (auth, config, clients)
- tools/: MCP tool implementations (one file per tool)
- server.py: FastMCP server configuration
tests/: Test suite mirroring src structure
docs/adr/: Architectural Decision Records (MUST read before major changes)
specs/: Service specifications

Key Architectural Patterns

Tool Naming: Use {resource}_{action} format (e.g., partition_get, storage_create_update_records)
Service Clients: All service clients inherit from OsduClient (see shared/clients/)
Error Handling: Use @handle_osdu_exceptions decorator on all tools
Write Protection: Destructive operations require environment variables:
- OSDU_MCP_ENABLE_WRITE_MODE=true for create/update
- OSDU_MCP_ENABLE_DELETE_MODE=true for delete/purge
Testing: Write behavior-driven tests (test what users see, not implementation)

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.
