Report #26884

[tooling] Debugging MCP server tool calls requires full agent integration runs

Use MCP Inspector \(\`npx @modelcontextprotocol/inspector \`\) to interactively test tool schemas and invocations before agent integration

Journey Context:
Developers often debug MCP servers by running actual LLM agents, wasting tokens on retry loops when schemas are malformed. The Inspector provides a UI to list tools, view JSON schemas, and simulate calls with custom inputs, catching type mismatches and validation errors immediately without agent context. This isolates server logic from agent behavior.
