+# Tool Search MCP Server
+
+这是一个基于 Higress Golang Filter 实现的 MCP Server，用于提供工具语义搜索功能。当前实现**仅支持向量语义搜索**（基于 Milvus 向量数据库），**不包含全文检索或混合搜索**。
+
+## 功能特性
+
+- **向量语义搜索**：使用 OpenAI 兼容的 Embedding API 将用户查询转换为向量，并在 Milvus 中进行相似度检索
+- **工具元数据支持**：从数据库中读取完整的工具定义（JSON 格式），并动态拼接工具名称
+- **全量工具列表**：支持获取数据库中所有可用工具
+- **可配置 Embedding 模型**：支持自定义模型、维度及 API 端点（如 DashScope）
+- **Milvus 集成**：通过标准 gRPC 接口连接 Milvus 向量数据库
+
+## 数据库要求（Milvus）
+
+本服务依赖 **Milvus 向量数据库**，需预先创建集合（Collection），其 Schema 应包含以下字段：
+
+| 字段名          | 类型                | 说明                      |

+## 配置示例
+
+
+Tool Search MCP Server 也可以作为 Higress 的一个模块进行配置。以下是一个在 Higress ConfigMap 中配置 Tool Search 的示例：
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: higress-config
+  namespace: higress-system
+data:
+  higress: |
+    mcpServer:
+      enable: true
+      sse_path_suffix: "/sse"
+      redis:
+        address: "<Redis IP>:6379"
+        username: ""
+        password: ""
+        db: 0
+      match_list:
+      - path_rewrite_prefix: ""
+        upstream_type: ""
+        enable_path_rewrite: false
+        match_rule_domain: "*"
+        match_rule_path: "/mcp-servers/tool-search"
+        match_rule_type: "prefix"
+      servers:
+      - path: "/mcp-servers/tool-search"
+        name: "tool-search"
+        type: "tool-search"
+        config:
+          vector:
+            type: "milvus"
+            host: "localhost"
+            port: 19530
+            database: "default"
+            tableName: "apig_mcp_tools"
+            username: "root"
+            password: "Milvus"
+            maxTools: 1000
+          embedding:
+            apiKey: "your-dashscope-api-key"
+            baseURL: "https://dashscope.aliyuncs.com/compatible-mode/v1"
+            model: "text-embedding-v4"
+            dimensions: 1024
+          description: "Higress 工具语义搜索服务"
+```
+
+## 工具搜索接口
+
+Tool Search MCP Server 提供以下 MCP 工具：
+
+### x_higress_tool_search
+
+基于语义相似度搜索最相关的工具。
+
+**输入参数**:
+
+| 参数名  | 类型   | 必填 | 说明 |
+|---------|--------|------|------|
+| `query` | string | 是   | 查询语句，用于与工具描述进行语义相似度比较 |
+| `topK`  | int    | 否   | 指定需要选择的工具数量，默认选择前10个工具 |
+
+**输出格式**:
+
+```
+{
+  "tools": [
+    {
+      "name": "server_name___tool_name",
+      "title": "Tool Title", 
+      "description": "Tool description",
+      "inputSchema": {...},
+      "outputSchema": {...}
+    }
+  ]
+}
+```
+
+
+## 搜索实现
+
+通过向量相似度进行搜索，索引配置如下
+- 使用 HNSW 索引算法进行向量索引
+- 默认参数：M=8, efConstruction=64
+- 相似度度量方式：内积（IP）

+## Configuration Example
+
+Use the algorithm of [gateway-api-inference-extension](https://github.com/kubernetes-sigs/gateway-api-inference-extension/blob/main/README.md):
+
+```yaml
+lb_type: endpoint
+lb_policy: metrics_based
+lb_config:
+  metric_policy: default
+  rate_limit: 0.6
+```
+
+Load balancing based on the current number of queued requests: 
+
+```yaml
+lb_type: endpoint
+lb_policy: metrics_based
+lb_config:
+  metric_policy: least
+  target_metric: vllm:num_requests_waiting
+  rate_limit: 0.6
+```
+
+Load balancing based on the number of requests currently being processed by the GPU:
+
+```yaml
+lb_type: endpoint
+lb_policy: metrics_based
+lb_config:
+  metric_policy: least
+  target_metric: vllm:num_requests_running
+  rate_limit: 0.6
+```
+
+# Cross-service load balancing
+
+## Configuration
+
+| 名称                | 数据类型         | 填写要求          | 默认值       | 描述                                 |
+|--------------------|-----------------|------------------|-------------|-------------------------------------|
+| `mode`      | string | required | | how to use cluster metrics, value of `[LeastBusy, LeastTotalLatency, LeastFirstTokenLatency ]` |
+| `service_list`      | []string | required | | service list of current route |
+| `rate_limit`      | string | optional | 1 | The maximum percentage of requests a single node can receive, value of 0~1 |
+| `cluster_header` | string | optional | `x-envoy-target-cluster` | By retrieving the value of this header, we can determine which backend service to route to |
+| `queue_size`      | int | optional | 100 | The metrics is calculated based on the number of most recent requests. |
+
+The meanings of the values for `mode` are as follows:
+
+- `LeastBusy`: Routes to the service with the fewest concurrent requests.
+- `LeastTotalLatency`: Routes to the service with the lowest response time (RT).
+- `LeastFirstTokenLatency`: Routes to the service with the lowest RT for the first packet.

 ## Configuration Example

 ```yaml
-lb_policy: least_busy
+lb_type: cluster
+lb_policy: cluster_metrics
 lb_config:
-  criticalModels:
-  - meta-llama/Llama-2-7b-hf
-  - sql-lora
-```
+  mode: LeastTotalLatency
+  rate_limit: 0.6
+  service_list:
+  - outbound|80||test-1.dns
+  - outbound|80||test-2.static
