Convert CSV/TSV text to a JSON array. POST { csv, delimiter?, header? }. Auto-detects comma vs tab, handles quoted fields and escaped quotes, and coerces numbers/booleans/empty→null. With header=true (default) each row becomes an object keyed by the header row; header=false returns arrays.
AI agents call dev.csv-to-json to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a data transformation utility that reads structured text input and outputs reformatted data. No side effects occur—the tool does not persist changes, execute code, move money, or destroy data. Despite the server's financial context (USDC payments via x402), this specific tool is purely computational and read-like in nature, converting one data format to another.
From the tool's definition Tool converts CSV/TSV text to JSON array format. It performs data transformation on input text without creating, modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
Convert CSV/TSV text to a JSON array. POST { csv, delimiter?, header? }. Auto-detects comma vs tab, handles quoted fields and escaped quotes, and coerces numbers/booleans/empty→null. With header=true (default) each row becomes an object keyed by the header row; header=false returns arrays. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for dev.csv-to-json: 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 Mcp. Nothing to install.
dev.csv-to-json 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 dev.csv-to-json 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 dev.csv-to-json. 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.
dev.csv-to-json is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
