Get TXT records for a domain.
AI agents call get_txt_records to retrieve information from Dnsdumpster without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs DNS reconnaissance by querying and retrieving TXT records—a read-only operation that gathers information about a domain without side effects. Severity is rated medium rather than low because DNS reconnaissance can enable reconnaissance attacks and reveal sensitive infrastructure information (SPF, DKIM, DMARC policies, etc.) that could be used to plan follow-up attacks, though the tool itself…
From the tool's definition Tool name 'get_txt_records' and description 'Get TXT records for a domain' indicate a retrieval operation with no modification or execution of external code.
Attacks that exploit this kind of access
Get TXT records for a domain. It is categorised as a Read tool in the Dnsdumpster MCP Server, which means it retrieves data without modifying state.
Register the Dnsdumpster MCP server in PolicyLayer and add a rule for get_txt_records: 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 Dnsdumpster. Nothing to install.
get_txt_records 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_txt_records 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_txt_records. 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_txt_records is provided by the Dnsdumpster MCP server (maxweeden/mcp-dnsdumpster). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
