Context Cost

~1,049Tokens (tool definitions)
~1.0 KBTypical response size
Moderate attention impact (0.82% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (7)

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟢describe_backlink_service

Read the verified offer, price, networks, fulfilment model, safety rules, and documentation without creating an order or moving funds.

Input Schema

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
🟢get_payment_requirements(network)

Read supported chains, official USDC contracts, gas assets, exact-price rules, and owner-approval guidance. This never creates an order or signs a transaction.

Input Schema

{
  "type": "object",
  "properties": {
    "network": {
      "type": "string",
      "enum": [
        "base",
        "polygon",
        "solana"
      ]
    }
  },
  "additionalProperties": false
}
🟡create_quote(email, password, target_url, anchor_text, quantity, ...)

Create one pending order and return exact USDC payment coordinates. This does not connect a wallet, sign, broadcast, or move funds. Keep the access token secret and obtain the wallet owner's approval before payment.

Input Schema

    },

    "access_token"
  ],
  "additionalProperties": false
}
🟢check_payment(order_id, access_token)

Ask Fresh SEM to look for the exact official-USDC payment from the quoted sending wallet and return the verified order state. This never signs or broadcasts.

Input Schema

{
  "type": "object",
  "properties": {
    "order_id": {
      "type": "string",
      "format": "uuid",
      "description": "Order UUID returned by create_quote."
    },
    "access_token": {
      "type": "string",
      "minLength": 32,
      "maxLength": 128,
      "description": "Original caller-generated Order-Access-Token. Keep it secret."
    }
  },
  "required": [
    "order_id",
    "access_token"
  ],
  "additionalProperties": false
}
🟡submit_payment_proof(order_id, access_token, transaction_hash)

Submit a transaction hash as a lookup aid. Fresh SEM independently verifies chain, official token, sender, recipient, amount, quote time, success, finality, and single use before fulfilment.

Input Schema

{
  "type": "object",
  "properties": {
    "order_id": {
      "type": "string",
      "format": "uuid",
      "description": "Order UUID returned by create_quote."
    },
    "access_token": {
      "type": "string",
      "minLength": 32,
      "maxLength": 128,
      "description": "Original caller-generated Order-Access-Token. Keep it secret."
    },
    "transaction_hash": {
      "type": "string",
      "minLength": 64,
      "maxLength": 100
    }
  },
  "required": [
    "order_id",
    "access_token",
    "transaction_hash"
  ],
  "additionalProperties": false
}
🟢get_order_status(order_id, access_token)

Return the authorized order state and continue safe payment reconciliation when appropriate. Treat an order as complete only when status is fulfilled.

Input Schema

{
  "type": "object",
  "properties": {
    "order_id": {
      "type": "string",
      "format": "uuid",
      "description": "Order UUID returned by create_quote."
    },
    "access_token": {
      "type": "string",
      "minLength": 32,
      "maxLength": 128,
      "description": "Original caller-generated Order-Access-Token. Keep it secret."
    }
  },
  "required": [
    "order_id",
    "access_token"
  ],
  "additionalProperties": false
}
🟢check_service_health

Read public endpoint availability and current MCP server information. This does not create an order or move funds.

Input Schema

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
