Response from ADK Answering Agent (experimental, answer may be inaccurate)

TLDR: The connection issue is most likely caused by an invalid API key. Please ensure you have replaced the placeholder "xxxxx" in TENCENT_MAP_API_KEY with your actual Tencent Map API key.

Hello! Thanks for reaching out. I've looked at the code you provided.

The most probable reason you are unable to connect to the Tencent Map MCP service is that the TENCENT_MAP_API_KEY is set to a placeholder value "xxxxx". The service will reject requests that do not have a valid API key.

To resolve this, please follow these steps:

1. Get a valid API Key: Make sure you have a valid API key from the Tencent LBS service console, as mentioned in the documentation you linked (https://lbs.qq.com).

2. Update your code: Replace the placeholder value in your script with your actual key:

   # Your Tencent Map API Key
   TENCENT_MAP_API_KEY = "YOUR_REAL_API_KEY" # <-- Replace with your key

3. Test the Connection Independently: Before running your ADK agent, it's a good practice to verify that the URL and key are working correctly on their own. You can use a command-line tool like curl to test the SSE endpoint. Open a terminal and run:

   # Replace YOUR_REAL_API_KEY with your key before running
   curl -i -H "Accept: text/event-stream" "https://mcp.map.qq.com/sse?key=YOUR_REAL_API_KEY&format=0"

   If the key is valid, you should receive a successful response (e.g., HTTP/1.1 200 OK) from the server. If you get an authentication error, please double-check your key in the Tencent Map developer console. This step helps confirm your key and network connectivity are working before involving the ADK agent. [1]

Once the curl command succeeds, your ADK agent configured with the same valid key should also be able to connect.

Let me know if you have any other questions!
