Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Share coding-agent sessions with your team: /share in one agent, /pickup in another.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
You need to fill in: RELAY_TOKEN
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Share coding-agent sessions with your team across Claude Code, Codex, OpenCode, Gemini CLI, Copilot CLI, Cursor and ZCode. Run /share in one agent; a teammate runs /pickup in whichever agent they use and carries on with the goal, decisions, next steps and recent conversation.
npm install -g session-relay
relay login --server https://relay.your-team.com # approve in the browser relay setup # adds the relay MCP server and /share, /pickup, /live to your agents
Then, in your agent:
/share
/share for bob /pickup /pickup alice's webhook retry work /live # working at the same time: see who's on what, message their session
You need a Session Relay server for your team; see self-hosting. Cloud hosting is coming soon.
