Get cross-chain swap quote via deBridge DLN. Preview mode (omit addresses) returns estimation only. Full mode (with addresses) returns complete order with transaction data.
AI agents call quoteSwap to retrieve information from deBridge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves swap quotes and estimations. Even in full mode it returns transaction data for review but does not execute or submit transactions. The server description also confirms 'read-only access to swap estimates.' No money movement occurs from this tool alone — it only previews/quotes. Severity is low as misuse only leaks quote data, not funds.
From the tool's definition 'Get cross-chain swap quote via deBridge DLN. Preview mode (omit addresses) returns estimation only. Full mode (with addresses) returns complete order with transaction data.'

Register the deBridge MCP Server MCP server in PolicyLayer and add a rule for quoteSwap: 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 deBridge MCP Server. Nothing to install.
quoteSwap 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 quoteSwap 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 quoteSwap. 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.
