AI agents call get_post_index_range to retrieve information from PTT MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve or query a range of post indices from the PTT bulletin board system. This is a data retrieval operation with no side effects—it queries metadata about posts rather than modifying, executing, or deleting them.

{
"version": "1",
"default": "deny",
"tools": {
"get_post_index_range": {}
