3232This SEP establishes a formal contributor ladder for the Model Context Protocol project, defining clear roles, responsibilities, and advancement criteria from first-time contributor through Core Maintainer. The ladder provides transparent pathways for community members to understand how they can grow their involvement and influence within the project.

34This SEP is a companion to [SEP-2149: MCP Group Governance and Charter Template](./2149-working-group-charter-template.md), which defines how Working Groups and Interest Groups operate. The two SEPs intersect: WG/IG leadership requires Member status on this ladder, and group participation is a recognized pathway to ladder advancement.

338338### Working Group and Interest Group Leadership
339339
340Working Group (WG) Leads and Interest Group (IG) Facilitators are a special form of community leadership that doesn't require Maintainer status. WG/IG leadership focuses on facilitation and coordination rather than merge authority. The full governance rules for WGs and IGs — including participation tiers, decision-making process, meeting requirements, and lifecycle — are defined in [SEP-2149: MCP Group Governance and Charter Template](./2149-working-group-charter-template.md).
