AI agents call analyze_type_coverage to retrieve information from dexMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes Pokemon type coverage information from a static dataset. There are no side effects, no data modifications, no code execution, and no destructive operations. It is purely a read operation that queries and summarizes existing Pokédex data. The severity is low because misuse would only result in incorrect analysis output with no blast radius beyond the application itself.
From the tool's definition The tool 'analyze_type_coverage' with description 'Summarize defensive type coverage for a roster' performs a data retrieval and analysis operation on Pokemon type data.
Attacks that exploit this kind of access
Summarize defensive type coverage for a roster. It is categorised as a Read tool in the dexMCP MCP Server, which means it retrieves data without modifying state.
Register the dex MCP server in PolicyLayer and add a rule for analyze_type_coverage: 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 dexMCP. Nothing to install.
analyze_type_coverage 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 analyze_type_coverage 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 analyze_type_coverage. 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.
analyze_type_coverage is provided by the dex MCP server (rajeevatla/dexmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
