Document agent tools for Resources and Prompts tabs

[mintlify]

Documents the new agent tool capabilities added to the MCP Inspector's Tools, Resources, and Prompts tabs.

Changes:

• Tools tab: Added "Agent visibility" section explaining that agents can observe the Tools tab state via ui_snapshot_app (tool list, selected tool, parameter names, result presence), and that tool execution uses the existing global ui_execute_tool.
• Resources tab: Added "Agent tool: ui_read_resource" section documenting the new tool that mirrors the Read button — covering concrete resource URIs/names, template resolution with templateArguments, truncation behavior, and the ui_snapshot_app discovery pattern.
• Prompts tab: Added "Agent tool: ui_get_prompt" section documenting the new tool that mirrors the Run button — covering name/title resolution, the arguments map, truncation behavior, and ui_snapshot_app discovery.

Files changed:

Summary by cubic

Update docs to show how agents work with the MCP Inspector’s Tools, Resources, and Prompts tabs. Adds ui_read_resource, ui_get_prompt, and visibility details via ui_snapshot_app and ui_execute_tool.

• New Features
  • Tools: Agents see tool list (names, up to 30), selection, parameter names, saved count, and result via ui_snapshot_app; execution uses ui_execute_tool.
  • Resources: ui_read_resource mirrors Read; takes URI/name or template; supports templateArguments (string-to-string); truncates large/binary results; discover via ui_snapshot_app.
  • Prompts: ui_get_prompt mirrors Run; takes name/title; supports arguments (string-to-string); truncates rendered messages; discover via ui_snapshot_app.
