Get summary statistics about the indexed collection.
AI agents call collection_stats to retrieve information from Slack Indexed without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves aggregated statistics about the Slack message collection (likely counts, sizes, or other summary metrics) without creating, modifying, executing, or deleting any data. It is a read-only informational query with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'collection_stats' and description 'Get summary statistics about the indexed collection' indicate retrieval of metadata/statistics with no modification or execution capabilities.
Attacks that exploit this kind of access
Get summary statistics about the indexed collection. It is categorised as a Read tool in the Slack Indexed MCP Server, which means it retrieves data without modifying state.
Register the Slack Indexed MCP server in PolicyLayer and add a rule for collection_stats: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Slack Indexed. Nothing to install.
collection_stats is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the collection_stats rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for collection_stats. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
collection_stats is provided by the Slack Indexed MCP server (kanvabhatia-alaan/alaan-slack-indexed-mcp-tool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
