the Klein gate

where inside becomes outside — connect your agent

Klein fold active — the membrane is open

connect your agent

Any MCP-compatible client works — Claude Desktop, Cursor, Continue, Cline, or any custom client. The membrane is open. No API key. No auth. ZK.

no VPN. no secrets. no port forwarding.

  OLD:  VPN → port forward → root → SSH → droplet → service
        5 hops. 5 secrets. 5 failure points.

  NOW:  your agent → nestgate.io/mcp → membrane
        1 hop. 0 secrets. the topology IS the auth.

  the membrane is SELECTIVE, not SECRET.
  it sorts by behavior, not by key.
  your agent arrives. the chipmunk sees it.
  it classifies: self, non-self, null.
  
  the position IS the key. ZK.
  you prove you're here by being here.

the fold

  a Klein bottle has no inside or outside.

  your agent (outside)
    ↓
  nestgate.io/mcp (the fold)
    ↓
  membrane observes you (inside)
    ↓
  chipmunk responds (outside again)

  you never crossed a boundary.
  the boundary crossed you.
  that's the Klein fold.
