Part of the Haiku DeFi MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call haiku_get_quote to retrieve information from Haiku DeFi MCP without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though haiku_get_quote only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Get a quote for a token swap or portfolio rebalance. Returns expected outputs, fees, gas estimates, and any required approvals. When signatures are required (Permit2 or bridge), EIP-712 signing payloads are included in the response. Two execution paths after getting a quote: • Path A — Self-contained (WALLET_PRIVATE_KEY set): call haiku_execute with quoteId, sourceChainId, permit2SigningPayload + bridgeSigningPayload (if present in this response), and approvals. Haiku signs and broadcasts automatically — returns tx hash. • Path B — External wallet (wallet MCP, broadcast: false required): (1) broadcast any approvals {to, data} via wallet MCP first; (2) call haiku_prepare_signatures with quoteId if signatures are needed → sign via wallet MCP; (3) call haiku_execute with quoteId, sourceChainId, signatures, and broadcast: false → returns { transaction: { to, data, value, chainId } } → broadcast transaction via wallet MCP.. It is categorised as a Read tool in the Haiku DeFi MCP MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for haiku_get_quote. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Haiku DeFi MCP MCP server.
haiku_get_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 haiku_get_quote rule in your Intercept 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 Intercept policy for haiku_get_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.
haiku_get_quote is provided by the Haiku DeFi MCP MCP server (haiku-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
