Tool returned multiple content, but MCPAdaptTool only returns the first

[dakl]

I'm wrapping a graphql service in an MCP server, providing an introspect tool that an agent can run to see what's available in the service. However running introspect like so introspect_tool(type_name="Query", depth=2) yields multiple items, but the MCPAdaptTool only keeps the first one, saying

tool introspect returned multiple content, using the first one

Here's what I'm doing:

with ToolCollection.from_mcp(
    {"url": "http://localhost:5000/mcp", "transport": "streamable-http"},
    trust_remote_code=True,
) as tool_collection:
    introspect_tool = [t for t in tool_collection.tools if t.name == "introspect"][0]

    graphql_schema = introspect_tool(type_name="Query", depth=2)
    print(graphql_schema)

which yields me

tool introspect returned multiple content, using the first one
type Person {
  id: UUID!
  name: String!
  age: String!
}

Is there any reason to only keep the first one? I want to get all the results and feed them to the agent. Perhaps an option to concatenate the contents into one item would be an option here?

What are the other items the tool is returning, @dakl?

Could you modify the tool to wrap all items into a list? Examples: https://github.com/modelcontextprotocol/python-sdk?tab=readme-ov-file#structured-output

Then you could use the new structured output feature as seen here:
