List signals (external feedback from Twitter, Reddit, support tickets, etc.) with optional filters.
AI agents call list_signals to retrieve information from IdeaLift MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays signals (external feedback data) without creating, modifying, deleting, or executing any operations. It is a straightforward data query operation with no side effects, fitting the 'Read' category. The low severity reflects minimal risk if misused by an AI agent—the worst outcome would be exposure of feedback data already collected by the system.
From the tool's definition Tool name 'list_signals' and description 'List signals (external feedback from Twitter, Reddit, support tickets, etc.) with optional filters' indicates retrieval of existing data with optional query parameters.

Register the IdeaLift MCP Server MCP server in PolicyLayer and add a rule for list_signals: 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 IdeaLift MCP Server. Nothing to install.
list_signals 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_signals 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_signals. 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_signals is provided by the IdeaLift MCP Server MCP server (startvest-llc/idealift-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
