Get statistics and information about a corpus
AI agents call get_corpus_info to retrieve information from Sketch Engine 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 corpus statistics and information without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that queries corpus metadata, consistent with other Read category tools on this server like get_collocations, get_concordance, and get_frequency_distribution. No side effects or data changes are possible.
From the tool's definition Tool name 'get_corpus_info' and description 'Get statistics and information about a corpus' indicate retrieval of metadata and statistics with no modification or execution of operations.

Register the Sketch Engine MCP Server MCP server in PolicyLayer and add a rule for get_corpus_info: 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 Sketch Engine MCP Server. Nothing to install.
get_corpus_info 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_corpus_info 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_corpus_info. 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_corpus_info is provided by the Sketch Engine MCP Server MCP server (riccap/sketch-engine-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
