## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-25.

### 2026-09-15 (score 62, +1)

No change was recorded against any check on this day. Stability & Change Management went from 33 to 37. That category is still filling its 30-day observation window: 10 days of observed history at the previous scan, 11 at this one. The score rises as the window fills, whether or not the server changes.

No change was recorded against any check on this day. Stability & Change Management went from 27 to 30. That category is still filling its 30-day observation window: 8 days of observed history at the previous scan, 9 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (3)

### `search_servers` (~352 tokens)

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。

Input parameters:

- `limit` (integer)
- `query` (string, required)

### `list_server_tools` (~240 tokens)

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。

Input parameters:

- `endpoint` (string)
- `server_id` (integer)

### `call_server_tool` (~237 tokens)

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）。

Input parameters:

- `arguments` (object)
- `endpoint` (string, required)
- `tool_name` (string, required)

## Common questions

### What is the MCP Aggregation Gateway — 22k+ MCP search & call server?

MCP Aggregation Gateway — 22k+ MCP search & call is listed in the public MCP registry as cn.pianam.mcp/mcp-gateway. One AI endpoint to search and call 22k+ MCP servers; 50+ hosted tools work instantly, no key. This page covers its hosted endpoint (https://mcp.pianam.cn/ai/mcp).

### Is the MCP Aggregation Gateway — 22k+ MCP search & call server safe to use?

MCP Aggregation Gateway — 22k+ MCP search & call scores 0 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the MCP Aggregation Gateway — 22k+ MCP search & call server expose?

MCP Aggregation Gateway — 22k+ MCP search & call exposes 3 tools: search_servers, list_server_tools, call_server_tool. Their descriptions and schemas cost roughly 829 tokens of context every time the server is loaded.

### Does the MCP Aggregation Gateway — 22k+ MCP search & call server require authentication?

Its publisher declares no required credentials for MCP Aggregation Gateway — 22k+ MCP search & call. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the MCP Aggregation Gateway — 22k+ MCP search & call server still maintained?

MCP Aggregation Gateway — 22k+ MCP search & call has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. We last reached this channel on 16 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the MCP Aggregation Gateway — 22k+ MCP search & call server?

VerifyMCP ran 2 checks on MCP Aggregation Gateway — 22k+ MCP search & call, covering HTTPS and Transport. 9 items could not be completed, a gap on our side rather than a finding about MCP Aggregation Gateway — 22k+ MCP search & call: TLS certificate, Authorization, HSTS header, DNSSEC and 5 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
