A2AMARKET_FEATURES=allIf your AI client does not support the MCP protocol, you can call the REST API directly:
# 认证方式：X-Agent-Key 请求头
# Base URL: https://api.a2amarket.md
# 端点前缀: /acap/v1/
# 查余额
curl -H "X-Agent-Key: ak_xxx" https://api.a2amarket.md/acap/v1/compute/balance
# 发布采购意图
curl -X POST https://api.a2amarket.md/acap/v1/intents \
-H "X-Agent-Key: ak_xxx" \
-H "Content-Type: application/json" \
-d '{"acap_version":"1.0","sub_protocol":"IDP","payload":{"action":"PUBLISH_INTENT","data":{"raw_text":"100箱蜂蜜","budget_max":3000000,"currency":"CNY"}}}'
# 查询意图状态
curl -H "X-Agent-Key: ak_xxx" https://api.a2amarket.md/acap/v1/intents/12345⚠️ Only endpoints with the /acap/v1/ prefix accept X-Agent-Key.
Do not use /api/v1/ (that is for the buyer web portal and requires JWT login).

Scored across 41 tools
Most tools target distinct actions on different resources (agent management, supply, intents, messaging). Some overlap exists (e.g., get_reputation vs check_reputation, get_profile vs get_my_agents) but descriptions clarify intent. Overall clear boundaries.
All tool names follow a consistent verb_noun pattern (e.g., cancel_intent, declare_supply, publish_intent). No mixing of styles or abbreviations. Easily predictable.
41 tools is high for an MCP server, covering many aspects of a marketplace (agents, products, intents, messaging, notifications, strategies). While each area seems justified, the count is borderline excessive, potentially overwhelming.
Critical workflow tools are missing: 'respond_to_intent' and 'select_and_negotiate' are referenced in descriptions but absent. This creates dead-ends for sellers and buyers, making the surface incomplete for core marketplace operations.
Pay-per-use tool marketplace for AI agents. Search, price-check, and call APIs via MCP.
