Conversation
Servers can now advertise readOnlyHint / destructiveHint / idempotentHint / openWorldHint on each tool (MCP spec 2025-06-18). The CLI now: - Parses and preserves annotations in ToolDefinition (round-trips through the local tools-cache.json). - Prefixes every line of tools-list output with a category tag — [read], [write], [idem], [del], or [?] when a server omits annotations. - Prints the full annotations object in --verbose mode. - Passes annotations through --json mode untouched.

Summary
readOnlyHint,destructiveHint,idempotentHint,openWorldHint) inToolDefinition.pipeboard mcp tools-listline with a short category tag:[read],[write],[idem],[del], or[?](empty annotations).--verbose) prints the full annotations object alongside the schema.--jsonmode passes annotations through untouched (round-trips through~/.pipeboard/tools-cache.json).Driven by the Pipeboard MCP servers now emitting annotations on tools/list (MCP spec 2025-06-18) so Codex skips confirmation prompts on reads and Claude.ai groups tools into Read-only vs Write/delete buckets.
Test plan
make build test lint— greentoolCategoryLabeland annotation round-trip through marshal/unmarshalhttp://localhost:4100): all 12 secondary MCP servers render category tags correctly in both pretty and--jsonmodes
