List available corpora
AI agents call get_corpora 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 queries and returns information about available corpora without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that retrieves metadata about corpus resources.
From the tool's definition Tool name 'get_corpora' and description 'List available corpora' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List available corpora. It is categorised as a Read tool in the Sketch Engine MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sketch Engine MCP Server MCP server in PolicyLayer and add a rule for get_corpora: 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_corpora 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_corpora 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_corpora. 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_corpora 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.
