One AI endpoint to search and call 22k+ MCP servers; 50+ hosted tools work instantly, no key.
MCP Aggregation Gateway — 22k+ MCP search & call is a remote MCP server published at mcp.pianam.cn. It has been probed 6 times since 9/12/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 483 ms, placing it among the faster endpoints. It offers a narrow, focused set of 3 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.

search_servers搜索 MCP Marketplace 平台目录中已收录的 MCP 服务(只读,共约 2.2 万个)。 【这是调用平台 MCP 的第一步】当你需要某个能力(如"查天气""查汇率""查热搜""查IP")时, 先用本工具按关键词检索,拿到 server_id 与 endpoint_url,然后: - 用 list_server_tools(server_id=...) 查看该服务提供哪些工具; - 再用 call_server_tool(endpoint=..., tool_name=..., arguments={...}) 实际调用。 参数: query: 搜索关键词,中英文均可。支持多个关键词(空格分隔,AND 匹配), 对名称(name)和描述(description)做模糊匹配。例如 "天气"、"weather"、"热搜 微博"。 limit: 返回条数上限,默认 10,最大 30。 返回:匹配的 MCP 列表,每条含: - id / name / slug / description(描述摘要) - endpoint_url: 远程 MCP 端点(若有;以 http/https 开头则 remote_direct=true,可直接远程调用) - remote_direct: 是否远程可直连 - alive / tools_count / checked_at: 平台能力验证状态(alive=1 表示最近验证存活,排在前面) 排序:验证存活(alive=1)且有远程端点的优先,其次按名称相关度。
querystringrequiredlimitintegerlist_server_tools列出某个远程 MCP 服务提供的全部工具(工具名、描述、入参 schema)。 【这是调用平台 MCP 的第二步】在 search_servers 找到目标服务后,传入它的 server_id (或直接传 endpoint_url),网关会以 MCP 客户端身份向目标服务发起 initialize + tools/list, 兼容 Streamable HTTP 与旧版 SSE 两种传输(超时 15 秒)。 参数: server_id: 平台目录中的服务 ID(来自 search_servers 返回的 id)。 endpoint: 也可直接给远程 MCP 端点 URL;但该 endpoint 必须已在平台库中登记(否则拒绝,防 SSRF)。 二选一,优先使用 server_id。 返回:目标服务的工具清单 [{name, description, inputSchema}] 与使用的传输类型。 拿到工具名后,用 call_server_tool(endpoint=..., tool_name=..., arguments=...) 调用。
server_idintegerendpointstringcall_server_tool通过网关代理调用某个远程 MCP 服务的具体工具,并把结果原样返回。 【这是调用平台 MCP 的第三步】在 search_servers 找到服务、list_server_tools 拿到工具名与 入参 schema 后,调用本工具实际执行。网关会向目标 MCP 发起 initialize + tools/call(超时 30 秒), 兼容 Streamable HTTP 与 SSE。 参数: endpoint: 目标远程 MCP 端点 URL(必须是平台库中已登记的地址,否则拒绝,防 SSRF)。 tool_name: 要调用的工具名(来自 list_server_tools)。 arguments: 工具入参字典,按该工具 inputSchema 填写。例如 {"city": "青岛", "days": 3}。 返回:目标工具的执行结果(content 文本/结构化内容原样透传,isError 标识是否业务错误)。

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
