Code Search (Exa)

Tool

Call the native MCP tool exa-code__get_code_context_exa directly. Parameters go in a JSON object.

Critical Rules

• Never run in main context. Spawn subagents or run sequentially.
• Always include the programming language in the query to reduce noise.
  • Good: "Go generics", "Python asyncio", "React 19 hooks"
  • Bad: "generics", "async", "hooks"
• Include framework + version when relevant: "Next.js 14", "Playwright Python".
• Include exact identifiers (function names, error messages) when you have them.

Token Tuning

Need	tokensNum
Quick snippet	1000-3000
Most tasks	5000 (default)
Complex integration	10000-20000

Call Examples

Tool: exa-code__get_code_context_exa

# Find code example
{ query: "Python asyncio aiohttp client example", tokensNum: 5000 }

# API usage
{ query: "OpenAI Responses API streaming Python", tokensNum: 8000 }

# Debugging

Output Format

Return:

1. Best minimal working snippet(s) — copy/paste ready
2. Notes — version constraints, gotchas
3. Sources — URLs if present
