Shift Mcp Server
Coordinate multiple AI agents editing the same repo so they do not stomp each other's files or duplicate work.
Overview
Shift MCP Server is a Build-phase MCP server that coordinates multiple AI agents working on the same codebase simultaneously.
What is this MCP server?
- Lightweight coordination layer when several AI agents touch one codebase at once
- stdio and streamable-http transports on Bun (npm @cyanheads/shift-mcp-server v0.1.5)
- Local streamable-http default at http://localhost:3010/mcp
- MCP_LOG_LEVEL for diagnosing concurrent agent conflicts during setup
- Focused scope: coordination, not full project management or git hosting
- Package version 0.1.5 as @cyanheads/shift-mcp-server
- Two transports: stdio and streamable-http (http://localhost:3010/mcp)
- Described as a lightweight coordination layer for simultaneous multi-agent editing
Community signal: 1 GitHub stars.
What problem does it solve?
Running two or more coding agents on one repo without coordination leads to conflicting edits and wasted tokens redoing the same tasks.
Who is it for?
Solo builders who routinely run parallel Claude Code, Cursor, or Codex sessions on a single monorepo during heavy implementation weeks.
Skip if: Single-agent workflows, large teams with formal assignment tools, or projects that only need standard git branching without MCP-level agent sync.
What do I get? / Deliverables
After you add Shift to MCP, agents can use its coordination tools to reduce collisions when parallel sessions edit shared files.
- MCP coordination layer for concurrent agents on one codebase
- Local stdio or streamable-http Shift endpoint (v0.1.5)
Recommended MCP Servers
Journey fit
Multi-agent coordination is a Build concern when you are actively shipping with parallel Claude or Cursor sessions on one codebase. Agent-tooling is the right shelf because Shift is infrastructure for how agents work together, not a end-user feature integration.
How it compares
Multi-agent coordination MCP, not a git host, PM board, or code review skill.
Common Questions / FAQ
Who is Shift MCP Server for?
It is for indie developers and agent-heavy builders who run multiple AI coding sessions on one repository and need a thin MCP coordination layer.
When should I use Shift MCP Server?
Use it during Build when you intentionally parallelize agents on the same codebase and want MCP-visible coordination instead of silent file clashes.
How do I add Shift MCP Server to my agent?
Install @cyanheads/shift-mcp-server, configure MCP with Bun run start:stdio or streamable-http at localhost:3010/mcp, and set MCP_LOG_LEVEL if you need setup diagnostics.
