check breakdown
✓Tools exposed — Server exposed 1 tool.
• sequentialthinking
✓Input schemas valid — All tools have a valid JSON-Schema input definition.
!Input schema quality — 1 schema-quality issue(s) across 1 tool(s).
sequentialthinking: inputSchema.additionalProperties is not set to false (extra args pass through silently)
→ Declare `required` for every schema that has properties, so agents know which params are mandatory.
→ Give every property a `description` and a concrete `type` (avoid bare `{}` placeholders).
→ Set `additionalProperties: false` on the top-level inputSchema so models can't silently pass extra, unvalidated arguments.
✓Output schemas — All tools declare a valid outputSchema.
✓Duplicate tool names — All tool names are unique.
✓Tool naming — All tool names use spec-legal characters.
✓Descriptions — Every tool and parameter is clearly described.
!Tool annotations — Annotation coverage 80% (4/5 hint fields set).
Some tools set a few hints but not all of title/readOnlyHint/destructiveHint/idempotentHint/openWorldHint.
→ Add annotations: title, readOnlyHint, destructiveHint, idempotentHint, openWorldHint.
→ These let clients gate risky calls and give agents/users a friendly display name — optional but valuable.
✓Tool titles — All tools declare a human-readable title.
!Server instructions — No top-level instructions declared.
→ Declare instructions to guide agents on when/how to use this server.
→ Return a non-empty `instructions` string in your InitializeResult — most SDKs let you set this alongside serverInfo.
✓Handshake + list latency — tools/list responded in 21ms.
