Passed

• Every tool has a well-formed, typed input schema.
• Every tool and parameter is described.
• Every tool declares whether it is read-only or destructive.
• No tool-poisoning patterns (hidden characters, instruction overrides, concealment, secret access, tool shadowing).
• Compact tool list (~1,395 tokens).
• Tool names are unique and portable across clients.
• 100.00% uptime over 30 days.
• No breaking contract changes in 30 days.

Largest tool definitions

• instruction_list ~224 tokens
• proposal_list ~204 tokens
• section_list ~200 tokens

Is the Xyzzylabs Wasm MCP server safe to connect to an AI agent?

Glimind scanned all 9 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
