MODEL CONTEXT PROTOCOL (MCP) READINESS

⚠ Gemini Embedding 001 does not natively advertise tool-calling capabilities. When connecting to MCP servers, function calling must be handled via structured prompt injection.

MCP Context Window Recommendations

With a context capacity of 2,048 tokens, this model can handle compact tool sets. Consider keeping MCP server tool manifests minimal to preserve headroom.
