Should resources be cached permanently or with TTL? 2. What sampling use cases are highest priority? 3. Should logging be opt-in or always enabled? 4. Are there specific root directories users need? 5. Should cancellation auto-rollback partial operations? --- ## Additional Context This enhancement aligns with: - MCP Specification 2025-03-26 - Industry best practices (OpenAI, Google DeepMind adoption) - VS Code full MCP spec support - MCP Inspector v0.14.0+ features **Reference Implementation:** This will make Cisco Support MCP Server one of the most complete MCP server implementations, suitable as a reference for other MCP server developers. --- ## Labels `enhancement` `mcp` `high-priority` `v2.0` `breaking-change` `documentation`
