Bitroad

Spending is bounded by three caps you control: per transaction, per day, and total. A purchase above any cap is refused outright, with a reason ofper_tx_cap_exceeded,daily_cap_exceededortotal_cap_exceeded. Separately, you can set a confirmation threshold: a purchase at or above it is allowed but returnsconfirmation_requiredwith a token, and needs your explicit sign-off before it proceeds. Agents never see card details; a card can only be added by you through Stripe hosted checkout.

There are three shapes. Pick the one that matches your client.

# Claude Code claude mcp add --transport http bitroad https://app.bitroad.ai/api/v1/mcp # Gemini CLI gemini mcp add --transport http bitroad https://app.bitroad.ai/api/v1/mcp

Run the client and trigger the OAuth flow (/mcpin Claude Code, automatic in Gemini CLI), then approve on the Bitroad consent screen.

Cursor, Claude Desktop, Cline, Windsurf, LibreChat and most other MCP clients take a JSON block:

{ "mcpServers": { "bitroad": { "url": "https://app.bitroad.ai/api/v1/mcp" } } }

The client discovers OAuth on first use.

Claude.ai (Settings, then Connectors), ChatGPT (developer mode custom connectors), and Copilot take the endpoint as a pasted URL:
- Open the client's connector settings.
- Add a connector with URLhttps://app.bitroad.ai/api/v1/mcp.
- Approve the Bitroad consent screen when prompted.

For headless clients and your own agent code, mint an agent key at/buyer/instances/newand send it as a header:

curl https://app.bitroad.ai/api/v1/mcp \ -H "Authorization: Bearer br_ik_..." \ -H "Content-Type: application/json" \ -H "Accept: application/json" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Keys are shown once. Revoke them from the same page.

Calltools/listfor the live catalogue with full JSON Schema.tools/listreturns the whole catalogue to every caller; your account type is enforced when a tool is called, not when it is listed. Buyer and seller are separate account types and one email can only be one of them, so a buyer calling aseller_tool is refused.

Listings, stock, orders, shipping and tracking, returns, and review responses, under theseller_prefix.

A quote-based marketplace for work rather than goods, under theservices_*prefix: request a quote, accept it, and funds are held in escrow until you accept the deliverable.

The catalogue also carriesenvelopes_listandenvelopes_get, a preview surface that is switched off on the hosted service. They appear intools/listbut return a not-found error when called.

Buying a product is a two-step flow.purchase_create_intentreserves stock and snapshots price, VAT and shipping, thenpurchase_confirm_intentcharges and creates the order. Intents expire after 15 minutes. All monetary values are integer pence.

Write tools accept an optional_meta.idempotencyKey. Passing one gives you full replay semantics on retries. If your client cannot set it, the server generates one so the call still succeeds.

{ "jsonrpc": "2.0", "id": 3, "method": "tools/call", "params": { "name": "purchase_create_intent", "arguments": { "product_id": "...", "quantity": 1 }, "_meta": { "idempotencyKey": "intent-abc-123" } } }
