Look up the lemma (base form) of a Norwegian word.
AI agents call lookup_word_lemma to retrieve information from DHLAB 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 information (word lemmas) from a read-only linguistic database with no side effects, no code execution, no data modification, and no destructive operations. It is a simple data retrieval operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'lookup_word_lemma' and description 'Look up the lemma (base form) of a Norwegian word' indicate a query operation that retrieves linguistic data without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Look up the lemma (base form) of a Norwegian word. It is categorised as a Read tool in the DHLAB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the DHLAB MCP Server MCP server in PolicyLayer and add a rule for lookup_word_lemma: 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 DHLAB MCP Server. Nothing to install.
lookup_word_lemma 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 lookup_word_lemma 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 lookup_word_lemma. 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.
lookup_word_lemma is provided by the DHLAB MCP Server MCP server (marksverdhei/dhlab-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
