Single-target operation
Part of the Spectra MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call get_morpho_rate to retrieve information from Spectra 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 get_morpho_rate 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 the current borrow rate and market state for a specific Morpho market. Provide the market's unique key (hex ID) and chain. Returns live borrow APY, supply APY, utilization, and liquidity — the data needed to calculate looping profitability. Use get_morpho_markets to discover market keys first. Important: Rates are live as-of-query and change continuously based on utilization. When planning a looping strategy, verify rates are still favorable before executing. A profitable spread (fixed yield > borrow rate) can turn negative if borrow rates spike. Use get_looping_strategy with these rates to calculate leveraged yield projections.. It is categorised as a Read tool in the Spectra MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for get_morpho_rate. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Spectra MCP server.
get_morpho_rate 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_morpho_rate 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 get_morpho_rate. 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_morpho_rate is provided by the Spectra MCP server (spectra-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
