smart-mcp-proxy/mcpproxy-go v0.32.0 on GitHub

This release adds support for MCP specification 0.4.9 with agent-discoverable disabled tools and introduces layered configuration for tool filtering, plus critical bug fixes for configuration and CI reliability.

New Features

Agent-discoverable disabled tools (MCP spec 0.4.9): Tools can now be marked as disabled while remaining discoverable by AI agents. This allows agents to see all available capabilities even when specific tools are administratively restricted, improving context awareness and error handling.
Layered tool filter configuration: Introduces a hierarchical configuration system where config_denied settings (administrator-defined restrictions) take precedence over user toggle preferences. This ensures security policies cannot be bypassed by user-level settings. (Teams edition primarily affected)

Bug Fixes

Fixed tool status classification: Corrected an issue where server tool status determination was not properly using runtime configuration authority, which could lead to incorrect tool availability states.
Fixed configuration snapshot cloning: Deep-copying of tool-filter slices now works correctly in Snapshot.Clone, preventing potential configuration corruption. Added regression tests to prevent recurrence.
Eliminated chronic E2E test timeouts: Resolved Docker verification waste in Runtime.Close that was causing persistent end-to-end test timeouts in CI pipelines.
