Get collocations for a query
AI agents call get_collocations 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 collocations (words that co-occur frequently) from a corpus linguistics database. It is a read-only query operation with no side effects—it does not modify data, execute code, delete anything, or commit financial transactions. The blast radius of misuse is minimal: an attacker could only retrieve linguistic data that is typically public or already accessible through the Sketch Engine interface.
From the tool's definition Tool name 'get_collocations' and description 'Get collocations for a query' indicate a retrieval operation.
Attacks that exploit this kind of access
Get collocations for a query. 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_collocations: 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_collocations 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_collocations 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_collocations. 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_collocations 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.
get_collocations is one line of Sketch Engine MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
