Get a friendly human-readable list of all available tools and their parameters
AI agents call list_available_tools to retrieve information from JS-Peer x DeFi MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure information retrieval tool that lists available tools and their parameters. It does not modify, execute, delete, or transfer any assets. The blast radius of misuse is minimal—an AI agent querying this tool could only learn about available capabilities, not abuse them directly. Classification as Read is appropriate.
From the tool's definition Tool name 'list_available_tools' and description 'Get a friendly human-readable list of all available tools and their parameters' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
Get a friendly human-readable list of all available tools and their parameters. It is categorised as a Read tool in the JS-Peer x DeFi MCP Server MCP Server, which means it retrieves data without modifying state.
Register the JS-Peer x DeFi MCP Server MCP server in PolicyLayer and add a rule for list_available_tools: 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 JS-Peer x DeFi MCP Server. Nothing to install.
list_available_tools 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 list_available_tools 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 list_available_tools. 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.
list_available_tools is provided by the JS-Peer x DeFi MCP Server MCP server (nkovaturient/js-peer-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
