Research direction
Start by reproducing the question_graphs failure in writer-sdk-mcp@latest and compare it with the working list_graphs and retrieve_graphs tools. Confirm whether a direct curl request succeeds, then inspect how the graph_ids array is serialized. The issue is done when question_graphs executes successfully and no longer fails silently.
Written by the indexing model from the issue text.
Description
MCP server version: 2.3.2 (writer-sdk-mcp@latest)
Working tools: list_graphs, retrieve_graphs, list_applications
Failing tool: question_graphs
Error: "Tool execution failed" with no details
Suspected cause: graph_ids array not being serialized correctly
Direct curl to API works (if confirmed in Step 1)
