Mar 1, 2026

March 2026 was focused on reducing integration risk and improving developer experience in the modelcontextprotocol repository by delivering comprehensive documentation enhancements around Authorization Server Metadata and Scope Management. Key updates consolidate multi-authorization server behavior, clarify the authorization server discovery metadata per RFC 8414, and enhance client-side scope management in step-up authorization. The work also adds guidance on binding persisted client credentials to specific authorization servers, clarifies that MCP uses the standard RFC well-known URI suffix (no MCP-specific suffix), and aligns scope handling with RFC 6749 and RFC 6750. Additional notes address hierarchical scopes and guidance against incremental scope changes within a single operation, including remote-dev considerations for homespace. These changes were implemented through three main commits: 4e578591e53760f5d9fe20f6d3453b30ee8b2ecd (SEP-2352: Clarify authorization server binding and multi-AS behavior), 298498d3f102426ac8e728818a59857da7c3623c (docs: explicitly specify RFC 8414 well-known URI suffix for MCP), and 443f75d9909618971d4217024ae094a648624de8 (SEP-2350: Clarify client-side scope accumulation in step-up authorization). The month did not include code-level bug fixes; instead, it focused on documentation clarity and RFC-aligned behavior to prevent misconfigurations and support smoother onboarding and token issuance.

June 2025: Key feature delivered in modelcontextprotocol/servers with Elicitation Feature Expanded Prompts, enriching user context by explicitly asking for favorite color, number, and pets. The work was implemented in a single commit updating src/everything/everything.ts (ebdfa7d84f62bbf813e8a871d36620350399b661). This enhancement improves data quality for elicitation flows and enables more personalized interactions, aligning with the June roadmap. Demonstrated strengths include precise feature scoping, clean code changes, and traceable commits that support reproducibility and collaboration.
