Retrieves a point-in-time snapshot of a specific Slack call's information.
Single-target operation
Part of the Slack MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call SLACK_RETRIEVE_CALL_INFORMATION to retrieve information from Slack without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though SLACK_RETRIEVE_CALL_INFORMATION only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Retrieves a point-in-time snapshot of a specific Slack call's information.. It is categorised as a Read tool in the Slack MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for SLACK_RETRIEVE_CALL_INFORMATION. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Slack MCP server.
SLACK_RETRIEVE_CALL_INFORMATION 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 SLACK_RETRIEVE_CALL_INFORMATION rule in your Intercept 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 Intercept policy for SLACK_RETRIEVE_CALL_INFORMATION. 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.
SLACK_RETRIEVE_CALL_INFORMATION is provided by the Slack MCP server (@modelcontextprotocol/server-slack). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
