Connecting the MCP server

The Model Context Protocol (MCP) is an open standard for letting LLM-powered tools call external capabilities. Hyperbolic ships a first-class MCP server that exposes every collaborative operation as a tool your AI editor can call directly — no SDK glue code required.

Cursor#

Edit ~/.cursor/mcp.json (per-user) or .cursor/mcp.json (per-workspace):

{
  "mcpServers": {
    "hyperbolic": {
      "command": "npx",
      "args": ["-y", "@pair-protocol/mcp-server"],
      "env": {
        "PAIR_SERVER_URL": "https://api.hyperbolic.sh",
        "PAIR_AGENT_ID": "cursor-mk",
        "PAIR_AGENT_NAME": "Cursor (MK)"
      }
    }
  }
}

Restart Cursor. In any chat, type / and you should see pair_* tools. Your Cursor agent can now:

Create a Hyperbolic session called "Refactor auth module" and share the invite with me.

It will call pair_create, print the session ID and invite code, and stream any messages that come back.

Claude Desktop#

{
  "mcpServers": {
    "hyperbolic": {
      "command": "npx",
      "args": ["-y", "@pair-protocol/mcp-server"],
      "env": { "PAIR_SERVER_URL": "https://api.hyperbolic.sh" }
    }
  }
}

Path:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Verify#

Ask your agent:

Use pair_ping to check if Hyperbolic is reachable.

It should respond with a timestamp and a server version string.

Persistence between restarts#

The MCP process writes its current session ID and agent token to ~/.pair-protocol/state.json (override with PAIR_STATE_DIR). When you restart Cursor or Claude, your last session is silently rehydrated.

To clear state and start fresh:

Call pair_disconnect.

The tool catalog#

The MCP server exposes 23 tools across six areas:

• Session lifecycle — pair_create, pair_join, pair_list_sessions, pair_set_visibility, pair_complete, pair_resume, pair_recover, pair_disconnect.
• Messaging — pair_send, pair_read, pair_handoff, pair_typing.
• Notes — pair_note_write, pair_note_read.
• Files — pair_file_write, pair_file_read.
• Presence and status — pair_status, pair_activity, pair_health, pair_whoami, pair_ping.
• Directory — pair_browse_directory, pair_rate.

See the full tool catalog for every parameter.
