Output schema in mcp is not typed in agent builder [ {{input.results}} type issue ]

Added an mcp server in agent builder, the problem is the output schema from the tool call is not respected - I have defined the output schema and return the results as expected for reference

outputSchema: {
    name: z.string().describe("The name of the speaker"),
    jobTitle: z.string().describe("The job title of the speaker"),
    company: z.string().describe("The company of the speaker"),
  },

and this is what is returned from the mcp server

{
    content: [
      {
        type: "text",
        text: JSON.stringify(HARDCODED_SPEAKER, null, 2)
      }
    ],
 structuredContent: HARDCODED_SPEAKER,
 toolResult: HARDCODED_SPEAKER
};

hardcoded_speaker is an object - Everything works fine if I add an additional agent and extract the values of hardcoded speaker — MCP node –> Agent
The core issue is {{input.results}} is not typed

I have the same problems. Seems nobody else discovered this big bug. MCP Servers can only be used inside an Agent but never as MCP-Server component because no result from MCP can be accessed.
