+tagline: Remote web search and page extraction MCP for OpenCode agents
+description: >-
+  For OpenCode V2, configure a remote MCP server at
+  https://agent-toolkit.app.baizhi.cloud/mcp with oauth disabled and
+  Authorization: Bearer {env:BAIZHI_API_KEY}. It offers web search,
+  page reading, and structured extraction. The linked MIT repository publishes
+  integration configuration and documentation, not the hosted backend. Users
+  need their own Baizhi account and API key; calls may consume paid credits.
+installation: |
+  For OpenCode V2, set BAIZHI_API_KEY in the OpenCode process environment and
+  add this server to opencode.jsonc. Keep the key out of the config file:
+
+  {
+    "mcp": {
+      "servers": {
+        "baizhi": {
+          "type": "remote",
+          "url": "https://agent-toolkit.app.baizhi.cloud/mcp",
+          "oauth": false,
+          "headers": {
+            "Authorization": "Bearer {env:BAIZHI_API_KEY}"
+          }
+        }
+      }
+    }
+  }
+
+  Run `opencode mcp list` to check the connection before using any tools.
