ask_question tool returns 'Repository not found' for indexed repositories

[abc57911]

Bug Description

The ask_question and read_wiki_contents tools return "Repository not found" error for repositories that are already indexed on DeepWiki.com (e.g., ArduPilot/ardupilot at https://deepwiki.com/ArduPilot/ardupilot).

However, the read_wiki_structure tool works correctly and returns the full wiki structure for the same repository.

Steps to Reproduce

1. Index a repository (e.g., ArduPilot/ardupilot) on DeepWiki.com
2. Try to call ask_question tool with that repository
3. Error: "Repository not found. Visit https://deepwiki.com to index it."

Expected Behavior

Both ask_question and read_wiki_structure should work for indexed repositories.

Environment

• DeepWiki MCP server (official)
• Claude Code CLI
• Repository: ArduPilot/ardupilot (confirmed indexed at https://deepwiki.com/ArduPilot/ardupilot)

Test Results

Tool	Status
read_wiki_structure	✅ Works
ask_question	❌ Repository not found
read_wiki_contents	❌ Repository not found

Possible Cause

The ask_question and read_wiki_contents tools may be using a different repository lookup/query mechanism than read_wiki_structure.
