The best AI changes.
Your context shouldn't.
Connect Claude, ChatGPT, Codex, Cursor, Copilot, or any MCP client to Stash. Each one can read the context you've already built and write new context back.
Build context with Claude today. Use it with ChatGPT tomorrow. No recap, no copy-paste.
Supported clients
If it speaks MCP, it works.
Any MCP client can read from and write back to your Stash. Same context, no per-client adapter, no middleware.
Setup
One endpoint. Three things to know.
Server endpoint
Point each MCP client here.
Every connected tool talks to the same Stash server, so they read from and write back to one place.
https://stash.bar/mcp
Authentication
OAuth, scoped per client.
Each AI client gets its own scoped token. Revoke any one without breaking the others.
Tool surface
Four tools. Read and write.
Create new context, search what matters, read the source, and browse entities.
stash_create
stash_search
stash_read
stash_entities
Per-client setup guides — Claude Desktop, ChatGPT, Codex, Cursor — coming with the public beta.
