OilPriceAPI for Gemini CLI 2.0.0

Breaking changes

• Replaces stale unprefixed tool guidance with the current opa_* MCP inventory.
• Pins oilpriceapi-mcp@3.0.0 and enables its 25-tool read-only scope by default.
• API keys are now managed as sensitive Gemini extension settings instead of assumed shell inheritance.

Grounding and safety

• Product, offer, freshness, catalog, entitlement, authentication, and data-rights answers use the reviewed product-facts contract.
• Data wording is source-timestamped and source/market-hours/plan dependent.
• 15-second Gemini MCP request timeout and explicit 401/402/403/429/malformed recovery.
• Connected-session grounding is distinguished from Gemini Search and pretrained model knowledge.

Verification

• 11 manifest/protocol tests, official Gemini CLI validation, isolated clean install, and zero-vulnerability npm audit.
• CI: https://github.com/OilpriceAPI/gemini-extension/actions/runs/29690492188
