MCP Context
MCP context bloat
Measure and reduce MCP tool definitions before they consume the agent context window.
When to use this
- Many servers are enabled globally
- Tool schemas consume thousands of tokens
- Agents pick wrong tools or ignore user intent
Implementation checklist
- Measure schema size
- Remove duplicate tools
- Shorten descriptions
- Prefer server-side search or Code Mode for large APIs
Common failure modes
- Prompt is too long
- Tool definitions too large
- Wrong tool selected
- Expensive sessions with little user work
