Describe the problem/error/question
I working with listTools/executeTools with MCP servers in n8n. I am seeing an issue where the schema is not being read properly. I see this issue with multiple MCP servers that function properly outside n8n (MCP inspector). I believe that I am hitting some variation of this (List Tools does not actually read the MCP inputSchema · Issue #72 · nerding-io/n8n-nodes-mcp · GitHub), which I think was resolved via this (feat: listTools returns schema types by QuentinPetel · Pull Request #44 · nerding-io/n8n-nodes-mcp · GitHub). I have checked my n8n version and the n8n-nodes-mcp version and should be on fixed versions. Any help would be appreciated.
