get_signals
AI agents call get_signals to retrieve information from Meridian Edge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description lowering confidence, the tool name and consistent pattern of sibling tools (all read operations on a public consensus data feed) indicate this retrieves market signals without side effects. No capability to modify, delete, execute commands, or move money. The 'get_' prefix and server context strongly suggest data retrieval.
From the tool's definition Tool name 'get_signals' and the context of a prediction market consensus data server suggest retrieval of market signals or data.
Attacks that exploit this kind of access
get_signals. It is categorised as a Read tool in the Meridian Edge MCP Server, which means it retrieves data without modifying state.
Register the Meridian Edge MCP server in PolicyLayer and add a rule for get_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 Meridian Edge. Nothing to install.
get_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 get_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 get_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.
get_signals is provided by the Meridian Edge MCP server (tmbot12/meridian-edge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
