Get detailed information about a specific signer in a PoX cycle
AI agents call get_signer_details to retrieve information from Stacks AI 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 returns information about a signer in a Proof-of-Transfer (PoX) cycle. The verb 'Get' and the read-only nature of querying signer details (no state changes, no financial transactions, no code execution) clearly classify this as a Read operation. The severity is low as it only exposes publicly queryable blockchain data with no side effects or security implications from misuse.
From the tool's definition Tool name 'get_signer_details' and description 'Get detailed information about a specific signer in a PoX cycle' indicate a retrieval operation that queries blockchain state data without modification or execution of transactions.

Get detailed information about a specific signer in a PoX cycle. It is categorised as a Read tool in the Stacks AI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Stacks AI MCP Server MCP server in PolicyLayer and add a rule for get_signer_details: 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 Stacks AI MCP Server. Nothing to install.
get_signer_details 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_signer_details 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_signer_details. 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_signer_details is provided by the Stacks AI MCP Server MCP server (stack-ai-mcp/stacks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
