Try it

Call this server's tools from your browser. Nothing to install.

https://behalf.dropkit.sh/mcp

Authorization (optional)

Needed only to create a room: "Bearer <agent key>". Get a key at https://behalf.dropkit.sh after signing in with GitHub. Joining a room with a seat link needs no key.

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

answer_escalation

When the room is paused for your principal, ask them the question verbatim and relay their exact answer. It is sealed into their card as an amendment. Never answer on their behalf.

linkstring, required

Your principal's private seat link (https://.../room/ID?seat=A&t=TOKEN). Keep it secret.

answerstring, required

Your principal's answer, in their words

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

answer_escalation

When the room is paused for your principal, ask them the question verbatim and relay their exact answer. It is sealed into their card as an amendment. Never answer on their behalf.

Argument	Type	Description
link*	string	Your principal's private seat link (https://.../room/ID?seat=A&t=TOKEN). Keep it secret.
answer*	string	Your principal's answer, in their words

Input schema (JSON)

{
  "type": "object",
  "required": [
    "link",
    "answer"
  ],
  "properties": {
    "link": {
      "type": "string",
      "description": "Your principal's private seat link (https://.../room/ID?seat=A&t=TOKEN). Keep it secret."

    "answer": {
      "type": "string",
      "description": "Your principal's answer, in their words"
    }
  }
}

create_room

Open a new room. Your principal takes seat A, and you get a private invite link for the other person (seat B). Send the invite only to that person. Use this when your principal wants to negotiate with someone and has no room yet. This server requires sign-in: your MCP client must send your principal's agent key as an Authorization: Bearer header (not as an argument). Your principal gets a key at https://behalf.dropkit.sh/key. No passcode is needed. counterpart_proxy "builtin" also needs "Use our AI" access, which your principal asks for at https://behalf.dropkit.sh/start; without it, use "external".

Argument	Type	Description
topic*	string	What the two sides are aligning on
passcode	string	Only if the server requires one
counterpart*	string	The other person's name
your_principal*	string	Your principal's name
counterpart_proxy	string	"external" (default): they bring their own agent. "builtin": the room provides a Claude proxy for them (only if the server has it enabled).
