Server instructions
# 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."
