Server exposes 4 tools with HTTP transport and clear audit-trail semantics. All tools have descriptions (10 - 200 chars) and input schemas with typed parameters. However, schemas lack depth: parameter descriptions are minimal or missing (e.g., 'limit' in list_sessions has no range guidance), output schemas are undocumented, and error handling provides no recovery guidance. Tool naming is verb-forward (health, ingest_records, list_sessions, list_records) and unambiguous. No tool annotations (readOnlyHint, destructiveHint) despite clear risk profiles. Composition is sound, each tool has one responsibility, but output chaining is weak (e.g., list_sessions returns session IDs but list_records requires explicit session filter; no cursor/pagination guidance).

• Document output schemas for list_sessions and list_records. Specify returned fields (e.g., session_id, upstream, start_time, last_seen_time, record_count for sessions; kind, id, timestamp_ms, payload for records) so LLMs can chain calls.
• Add min/max constraints to numeric parameters in schema. Change 'limit' descriptions to: 'Maximum number of records to return (default 500, min 1, max 2000)' and add minItems/maxItems to JSON Schema.
• Add tool annotations: mark ingest_records with destructiveHint=true, list_* with readOnlyHint=true. This signals safety profile to agents without requiring description parsing.
• Enhance error messages with recovery hints. E.g., 'Batch too large (max 1000). Retry with fewer records or split into multiple calls.' for batch size violations.
• Add pagination support to list_records. Return a next_cursor field and accept cursor parameter to enable iteration over large result sets without context explosion.
