Code mode support for SerpAPI MCP #34

Code mode allows to speed-up bulk search while lower token cost.

Fast MCP 3.0 supports this already.

mcp = FastMCP("Server", transforms=[CodeMode(sandbox_provider=sandbox)])

The requirements would be:

• Test if MCP mode is worth it.
• Make sure there is no security hole in the currently deploy implementation. Execution the code in the back-end is generally a terrible idea.
• Allow user to extend SerpAPI MCP server in Python (following SOLID principles).
• Allow user to define declare their own sandbox
• Document the feature, and performance benchmark associated emphasis on cost saving
