    Prompt Examples

    Below are examples of prompts you might use in an MCP-compatible client (e.g., Claude Desktop) and the expected responses after the analysis_token tool is invoked.

    Prompt:

    "Can you analyze the Solana token at address 9VxExA1iRPbuLLdSJ2rB3nyBxsyLReT4aqzZBMaBaY1p?"

    Response:

    plaintext
    I've analyzed the token at address 9VxExA1iRPbuLLdSJ2rB3nyBxsyLReT4aqzZBMaBaY1p. Here's the summary:
    
    - Token Name: REVSHARE (Symbol: REVS)
    - Snif Score: 55/100 (Moderate risk)
    - Market Cap: $288,875.29
    - Price: $0.000297
    - Total Supply: 971,266,696.90 tokens
    - Risks:
      - High (3 risks):
        - Mintable risks found: True
        - Freeze risks found: True
        - Permanent control risks found: True
        - (Other factors: False)
      - Moderate (1 risk):

      - Freeze Disabled: Yes
      - LP Burned: No
      - Top 10 Holders Significant: No
    
    This token has moderate risks due to potential control issues and liquidity concerns, but minting and freezing are disabled for added safety.

    Prompt:

    "What’s the risk profile of the token So11111111111111111111111111111111111111112?"

    Response:

    plaintext
    Here's the risk profile for the token at address So11111111111111111111111111111111111111112:
    
    - Token Name: Wrapped SOL (Symbol: SOL)
    - Snif Score: 92/100 (Low risk)
    - Market Cap: $82,345,678.90
    - Price: $176.54
    - Total Supply: 466,567,890.12 tokens

      - LP Burned: Yes
      - Top 10 Holders Significant: No
    
    Wrapped SOL is a low-risk token with strong audit protections and only a minor liquidity concern, typical for a well-established asset.

    Prompt:

    "Tell me about the token 4k3Dyjzvzp8eMZWUXbBCjEvwSkkk59S5iCNLY3QrkX6R."

    Response:

    plaintext
    Here's the analysis for the token at address 4k3Dyjzvzp8eMZWUXbBCjEvwSkkk59S5iCNLY3QrkX6R:
