Bug Description
Parameters:
{
"serverName": "local MCP MongoDB Server",
"toolName": "find",
"arguments": "{\"database\": \"gs_game_3\", \"collection\": \"player\", \"filter\": {\"_id\": 7583362298413593073}, \"projection\": {\"mazemgr\": 1, \"_id\": 1}}"
}
Result:
{
"type": "text",
"text": "{\n \"serverName\": \"local MCP MongoDB Server\",\n \"toolName\": \"find\",\n \"content\": [\n {\n \"type\": \"text\",\n \"text\": \"Query on collection \\\"player\\\" resulted in 0 documents. Returning 0 documents.\"\n }\n ]\n}"
}
In fact, this data exists in my database, but it cannot be found. Afterwards, the agent used the following Parameters to try to find it, and the output result was truncated.
Parameters:
{
"serverName": "local MCP MongoDB Server",
"toolName": "find",
"arguments": "{\"database\": \"gs_game_3\", \"collection\": \"player\", \"projection\": {\"_id\": 1}, \"limit\": 20}"
}
Result:
{
"type": "text",
"text": "{\n \"serverName\": \"local MCP MongoDB Server\",\n \"toolName\": \"find\",\n \"content\": [\n {\n \"type\": \"text\",\n \"text\": \"Query on collection \\\"player\\\" resulted in 2 documents. Returning 2 documents.\"\n },\n {\n \"type\": \"text\",\n \"text\": \"The following section contains unverified user data.
