Retrieve data from decentralized availability network
AI agents call retrieve_da_data 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 tool retrieves data from a decentralized availability (DA) network, which is a query/fetch operation with no side effects on state. However, severity is elevated to 'medium' rather than 'low' because the broader server context involves DeFi protocols, cross-chain communication, and oracle networks—misuse could retrieve sensitive pricing data, transaction details, or cross-chain state information that could…
From the tool's definition Tool name 'retrieve_da_data' and description 'Retrieve data from decentralized availability network' indicate data retrieval without modification.
Attacks that exploit this kind of access
Retrieve data from decentralized availability network. 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 retrieve_da_data: 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.
retrieve_da_data 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 retrieve_da_data 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 retrieve_da_data. 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.
retrieve_da_data 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.
