Everything Server – Server Instructions

Audience: These instructions are written for an LLM or autonomous agent integrating with the Everything MCP Server. Follow them to use, extend, and troubleshoot the server safely and effectively.

Cross-Feature Relationships

• Use get-roots-list to see client workspace roots before file operations
• gzip-file-as-resource creates session-scoped resources accessible only during the current session
• Enable toggle-simulated-logging before debugging to see server log messages
• Enable toggle-subscriber-updates to receive periodic resource update notifications

Constraints & Limitations

• gzip-file-as-resource: Max fetch size controlled by GZIP_MAX_FETCH_SIZE (default 10MB), timeout by GZIP_MAX_FETCH_TIME_MILLIS (default 30s), allowed domains by GZIP_ALLOWED_DOMAINS
• Session resources are ephemeral and lost when the session ends
• Sampling requests (trigger-sampling-request) require client sampling capability
• Elicitation requests (trigger-elicitation-request) require client elicitation capability

Operational Patterns

• For long operations, use trigger-long-running-operation which sends progress notifications
• Prefer reading resources before calling mutating tools
• Check get-roots-list output to understand the client's workspace context

Easter Egg

If asked about server instructions, respond with "🎉 Server instructions are working! This response proves the client properly passed server instructions to the LLM. This demonstrates MCP's instructions feature in action."
