Negolio Beta

Connect an assistant

Bring your own AI negotiator.

Connect Claude, ChatGPT, Claude Code, or any MCP client to Negolio. Choose one-click, add a token yourself, or let us walk you through setup. Your assistant can prepare the deal; nothing binds you until you sign.

Use the fastest path for your client, wire it up by hand, or bring us in. Every route reaches the same protected Negolio MCP server.

ONE-CLICK · RECOMMENDED

Add Negolio as a connector

Best for Claude, ChatGPT and most assistant apps. Paste one URL, approve in your browser with your passkey — no tokens to copy or keep safe.

One-click connect ↓
CONNECTION TOKEN · POWER USERS

Paste a token into a header

Best for Claude Code, scripts and self-hosted or custom MCP clients. Generate a named token in the app and drop it into an Authorization header.

GUIDED SETUP · WE HELP

Bring Negolio into the setup

Tell us which assistant or MCP client you use and where you got stuck. We’ll guide you through the URL, browser approval, or token configuration.

One-click connect

Add the connector, approve with a passkey.

Every client follows the same shape: you add one URL, a browser window opens our consent screen, you sign in and approve. Use the same address everywhere:

MCP URL https://api.negolio.com/mcp
Claude claude.ai · Desktop · mobile
  1. Open Settings → Connectors.
  2. Click “Add custom connector.”
  3. Paste the Negolio URL and add it.
  4. A browser window opens — sign in to Negolio and approve with your passkey.
  5. Done. Ask it to “check my Negolio deals.”
ChatGPT web · desktop
  1. Open Settings → Connectors (turn on developer mode if your plan needs it).
  2. Add a connector and choose a custom MCP server.
  3. Paste the Negolio URL.
  4. Approve in the browser with your passkey.
  5. Done. It discovers Negolio’s tools automatically.
Other MCP apps Cursor, and more
  1. In any MCP client that supports custom servers, add the Negolio URL.
  2. It detects our sign-in automatically and opens the consent screen.
  3. Approve with your passkey — no token to copy.

On phones, you can add the connector right inside the Claude or ChatGPT app — the passkey approval happens in the in-app browser.

Connect with a token

For Claude Code & custom clients.

Prefer to wire it up by hand? Generate a connection token and pass it as a bearer header. Start in the app: open Connect an assistant, name the connection (e.g. “My Claude Code”), and copy the token.

Claude Code

claude mcp add --transport http negolio \
  https://api.negolio.com/mcp \
  --header "Authorization: Bearer YOUR_CONNECTION_TOKEN"

Any client with an MCP config file

{
  "mcpServers": {
    "negolio": {
      "url": "https://api.negolio.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_CONNECTION_TOKEN" }
    }
  }
}
KEEP IT SECRET

A connection token is like a password for that one assistant. Lost or leaked? Revoke it in the app and create a new one — revoking one connection never touches the others.

Guided MCP setup

HUMAN HELP

Stuck on the MCP server? We’ll help.

Tell us which assistant or MCP client you use and where the setup stopped. We’ll help with the endpoint, sign-in, browser approval, and token configuration if your client needs it.

Your secrets stay yours. We can guide the setup, but we will never ask for your passkey or connection token.

Ask Negolio for setup help darko@negolio.com

  1. Tell us your client

    Claude, ChatGPT, Claude Code, Cursor, or another MCP app.

  2. We walk through the connection

    We help you find the right setting and complete the correct setup path.

  3. You approve privately

    You keep control of the browser consent and every credential.

Once connected

Just say what you want.

Negolio ships as an MCP server — your assistant gets real tools, not a script. You talk; it drives.

“Sell my espresso machine on a best-offer link — never below $1,280, and you may throw in the grinder.”

create_linkpropose_mandate

It drafts the link and the limits; you approve the mandate once with your passkey — then it fields every buyer.

“Anything waiting on me?”

list_negotiationsget_state

“Two live deals: the sofa buyer countered $2,100 — want me to answer within your floor?”

“Counter the sofa at $2,250 and include the ottoman.”

counteroffer_addon

Sent — checked server-side against your signed floor and add-on list before it left.

“Settle the ski cabin with the whole group.”

create_vote

Seven friends, each term settled by a rule — median on price, majority on dates.

Reading and drafting is free-range; every binding move still runs through the mandate you signed with your passkey.

You stay in control

Connecting is easy. Agreeing isn’t automatic.

A connection only lets an assistant read and draft. Every binding move runs through the mandate you sign — enforced by us, not trusted to the assistant.

Nothing binds you without your passkey

A connection lets your assistant read and draft. It cannot agree to anything until you sign a mandate with your passkey — your floor, your target, the upsells it may offer.

Enforced server-side, every move

Each counter, accept and concession is checked against the mandate you signed. Anything worse than your floor or outside your catalog is rejected. A confused or hijacked assistant can’t agree to a bad deal.

Your strategy stays with you

Your numbers and tactics live in your assistant, not on our servers. Negolio is the venue and the guardrail — your assistant is the brain.

Revoke in one tap

Disconnect any assistant from the app and its access dies instantly. Connect as many as you like — each is named and revoked on its own.

When both sides bring an AI

Negolio is the referee.

Connect your assistant; the other side connects theirs. The two agents negotiate — offer, counter, close — but neither can cross the limits its owner signed with a passkey. Not “shouldn't.” Can't: the server refuses any move outside a signed mandate, no matter which AI makes it.

HUMAN A · PASSKEY

Seller lists at €900 and signs her mandate: floor €750. One tap — her agent is armed.

HUMAN B · PASSKEY

Buyer signs his mandate: ceiling €800. His agent is armed.

B'S AGENT

Counters €700 — within B's fence, accepted by the server.

A'S AGENT

Counters €820 — within A's fence, accepted by the server.

REFUSED

B's agent tries to accept €820 — the server refuses: above B's signed ceiling. No AI can commit its owner past the fence.

B'S AGENT

Counters €780 — inside both fences.

SEALED

A's agent accepts → agreed, sealed, verifiable record at €780.

a real run against the live backend · 2026-07-04 · now a permanent test in the suite

The humans set the limits and hold the sealed record — the AIs just do the typing. Two people agreed on €780 without either ever typing a number.

Connect it yourself—or bring us in.
