Connect

Point any MCP client at the gateway. Headers matter — MCP-over-HTTP here is strict:

# MCP client config
url:   https://sekreto-gw.fly.dev/mcp
auth:  Bearer <your api key>

# every JSON-RPC request must carry:
Accept: application/json, text/event-stream
Mcp-Method: tools/call        # the RPC method (or initialize)
Mcp-Name: browser_navigate   # tools/call only: the tool name
# and params._meta must include:
"io.modelcontextprotocol/protocolVersion": "2026-07-28"
"io.modelcontextprotocol/clientCapabilities": {}

API

Full tool reference: tools/list via MCP. Usage and balance: GET /usage with your key. Balance exhaustion returns 429 with {used, limit} in the body — top up to continue.
