Compare the behavior of two words/lemmas via their collocations. Returns scores indicating which collocation is more typical of which word, useful for observing differences between similar words.
AI agents call get_word_sketch_diff 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 corpus linguistics data to retrieve and compare collocation patterns between two words. It performs data retrieval only, without modifying, deleting, or executing external operations. The output is analytical information derived from existing corpus data, making it a straightforward Read category with low severity, as misuse would only expose analytical results from a text corpus.
From the tool's definition Tool description states it 'Compare[s] the behavior of two words/lemmas via their collocations' and 'Returns scores' — a retrieval and comparison operation.
Attacks that exploit this kind of access
Compare the behavior of two words/lemmas via their collocations. Returns scores indicating which collocation is more typical of which word, useful for observing differences between similar words. 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_word_sketch_diff: 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_word_sketch_diff 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_word_sketch_diff 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_word_sketch_diff. 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_word_sketch_diff 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.
