AI agents call get_swap_quote to retrieve information from Solblade without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries pricing or swap information without modifying data, executing transactions, or causing side effects. It is purely informational and aligns with the Read category of data retrieval operations. The explicit disclaimer that it does not execute further confirms there are no financial or execution risks.
From the tool's definition Tool description explicitly states 'read-only, does not execute'. It retrieves swap quote data from Jupiter without performing any transaction or state change.
Attacks that exploit this kind of access
Get a Jupiter swap quote (read-only, does not execute). It is categorised as a Read tool in the Solblade MCP Server, which means it retrieves data without modifying state.
Register the Solblade MCP server in PolicyLayer and add a rule for get_swap_quote: 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 Solblade. Nothing to install.
get_swap_quote 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 get_swap_quote 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 get_swap_quote. 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.
get_swap_quote is provided by the Solblade MCP server (nullxnothing/solblade). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
