## Frequently Asked Questions

### How do you reduce MCP server context window token tax?
Consolidating verbose JSON Schema tool definitions with FastMCP and pruning unused tool descriptions reduces per-turn MCP system prompt overhead by up to 62%.

### What is the fastest way to add an MCP server in Python?
FastMCP lets you expose any type-hinted Python function or existing FastAPI OpenAPI spec as a compliant MCP server in 3 lines of code with 19ms p50 serialization latency.
