Given an MCP server, shows the declared ToolAnnotations for security assessments
Paste an MCP server's tools/list JSON (or point it at a live server) and see which tool annotations — readOnlyHint, destructiveHint, idempotentHint, openWorldHint — it actually declares, versus what the spec's conservative defaults assume when a hint is missing.
Annotations are self-declared, unverified hints, not enforced controls. This tool exists to make that gap visible before you decide which MCP tool actions to allow.
Then open http://localhost:8321, and either:
- give it an http(s):// MCP server URL (OAuth via mcp-remote) or a stdio command, and it fetches tools/list for you, or - paste tools/list JSON directly.
Results can also be published as a secret GitHub gist via gh.
