Return recent lead events from DB_CORE.
AI agents call get_leads to retrieve information from Inkwell MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data (lead events) from a database without creating, modifying, deleting, or executing external operations. It is a straightforward read operation with minimal blast radius if misused by an AI agent, as it only exposes existing data retrieval.
From the tool's definition Tool description states 'Return recent lead events from DB_CORE' — a retrieval operation with no modification or deletion.

Register the Inkwell MCP Server MCP server in PolicyLayer and add a rule for get_leads: 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 Inkwell MCP Server. Nothing to install.
get_leads 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_leads 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_leads. 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.
