find_concordances
AI agents call find_concordances 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.
Concordance finding is a standard text analysis operation that retrieves contextual occurrences of words or phrases from a corpus without modifying data or executing arbitrary code. The server's purpose (text/image search, analysis of Norwegian digital collections) confirms this is a data retrieval tool.
From the tool's definition Tool name 'find_concordances' and sibling tools like 'word_concordance', 'search_texts', 'search_images', and 'lookup_word_lemma' indicate this is a query/retrieval operation over a read-only digital humanities corpus.

find_concordances. 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 find_concordances: 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.
find_concordances 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 find_concordances 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 find_concordances. 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.
find_concordances 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.
