list_calls
AI agents call list_calls to retrieve information from Salesloft MCP Demo Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to list or retrieve call records from the Salesloft system. It performs no modifications, deletions, or financial transactions. The sibling tools (get_call, search_calls) and server description focused on querying and analyzing transcripts confirm this is a Read operation. Severity is low because listing calls exposes sales data but does not permit modification or destruction of records.
From the tool's definition Tool name 'list_calls' combined with sibling tools 'get_call' and 'search_calls' indicates retrieval operations. Server description emphasizes 'analysis' and 'search conversations' without modification.

list_calls. It is categorised as a Read tool in the Salesloft MCP Demo Server MCP Server, which means it retrieves data without modifying state.
Register the Salesloft MCP Demo Server MCP server in PolicyLayer and add a rule for list_calls: 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 Salesloft MCP Demo Server. Nothing to install.
list_calls 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 list_calls 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 list_calls. 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.
list_calls is provided by the Salesloft MCP Demo Server MCP server (wgalyean50/salesloft-mcp-demo1). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
