GET /v1/contact/get?record_id={uuid}. Retrieve a specific contact by record UUID. Never charges credits.
AI agents call get_contact to retrieve information from DataMerge MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves contact data by UUID. It performs no creation, modification, deletion, or execution of external operations. The GET HTTP method and retrieval semantics clearly indicate a Read category classification with low severity, as misuse would only expose existing data without enabling destructive or financial harm.
From the tool's definition Tool name 'get_contact' with description 'Retrieve a specific contact by record UUID' explicitly performs a GET operation that retrieves data without side effects.
Attacks that exploit this kind of access
GET /v1/contact/get?record_id={uuid}. Retrieve a specific contact by record UUID. Never charges credits. It is categorised as a Read tool in the DataMerge MCP MCP Server, which means it retrieves data without modifying state.
Register the DataMerge MCP server in PolicyLayer and add a rule for get_contact: 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 DataMerge MCP. Nothing to install.
get_contact 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_contact 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_contact. 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_contact is provided by the DataMerge MCP server (poolside-ventures/datamerge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
