The OpenAPI converter intends to skip CORS OPTIONS operations, but kin-openapi returns uppercase HTTP methods. Comparing with lowercase options creates an extra OPTIONS tool. Compare case-insensitively and strengthen the existing skip-options test to require exactly one tool.

Validation:

• Strengthened existing regression fails before the fix (two tools instead of one).
• go test ./pkg/openapi -count=1 passes.
• go build ./cmd/... passes on Windows with Go 1.26.3.

The test scope corresponds to make test TEST_PACKAGES=./pkg/openapi; the full service suite was not run because this task permits offline synthetic fixtures only. No live MCP servers, model APIs, or backend services were started.

Summary by Sourcery

Prevent OpenAPI conversion from generating tools for CORS OPTIONS operations.

Bug Fixes:

• Skip CORS OPTIONS operations regardless of HTTP method casing so they do not generate unintended tools.

Tests:

• Strengthen the OpenAPI converter regression test to require exactly one generated tool.

Reviewer's Guide

The converter now skips OPTIONS operations case-insensitively, preventing an unwanted CORS tool when kin-openapi reports uppercase methods; the regression test requires exactly one generated tool and confirms the existing GET behavior.

Make CORS OPTIONS filtering robust to the uppercase HTTP methods returned by kin-openapi.	Use case-insensitive comparison when identifying OPTIONS operations. Continue excluding OPTIONS operations from generated tools while preserving other methods.	pkg/openapi/converter.go
Strengthen regression coverage to verify that OPTIONS operations do not produce extra tools.	Require the converted configuration to contain exactly one tool. Retain validation that the GET tool is present and uses the operation summary as its description.	pkg/openapi/converter_test.go
