AI agents call bridge_quote to retrieve information from Logiqical without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves a quote and returns an unsigned transaction — it does not execute or broadcast anything. The actual transaction requires the agent to sign and presumably broadcast separately (see 'broadcast_tx' sibling tool). However, the returned unsigned tx could be misused, and the context is financial/trading infrastructure, so severity is medium despite being a read operation.
From the tool's definition Get a cross-chain bridge quote with unsigned transaction
Attacks that exploit this kind of access
Get a cross-chain bridge quote with unsigned transaction. Agent signs the tx on the source chain. It is categorised as a Read tool in the Logiqical MCP Server, which means it retrieves data without modifying state.
Register the Logiqical MCP server in PolicyLayer and add a rule for bridge_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 Logiqical. Nothing to install.
bridge_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 bridge_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 bridge_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.
bridge_quote is provided by the Logiqical MCP server (logiqical-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
