Scan all Spectra chains for the best risk-adjusted yield opportunities, sized to your capital. Unlike get_best_fixed_yields (which ranks by raw APY), this tool computes: - Entry price impact at YOUR capital size (a 50% APY pool with $10K liquidity is useless at $500K) - Effective APY after amort...

Part of the Spectra MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call scan_opportunities 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 scan_opportunities 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.

Scan all Spectra chains for the best risk-adjusted yield opportunities, sized to your capital. Unlike get_best_fixed_yields (which ranks by raw APY), this tool computes: - Entry price impact at YOUR capital size (a 50% APY pool with $10K liquidity is useless at $500K) - Effective APY after amortizing entry cost over days to maturity - Morpho looping availability and optimal leveraged net APY - Pool capacity (max capital before price impact exceeds your threshold) - IBT APR composition (organic base yield vs external incentive programs) - Points program multipliers and asset tags per opportunity - Risk warnings (low liquidity, short maturity, high impact) - MetaVault alternatives (curated auto-rolling LP vaults with YT compounding) Returns opportunities ranked by effective APY (or looping net APY where available). Ranking logic: when a profitable Morpho looping market exists, ranks by looping net APY with cumulative entry cost amortized; otherwise ranks by effective APY (base APY minus annualized entry cost). MetaVaults are shown in a separate section (not interleaved with PT rankings) because they have different risk profiles: variable APY, curator-managed, auto-rolling positions. Set include_metavaults=false to skip MetaVault scanning. Use get_looping_strategy to drill into a specific opportunity's leverage details. Use get_pool_activity and get_portfolio to investigate trading patterns and positions. Use model_metavault_strategy to model MetaVault looping economics.. 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 scan_opportunities. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Spectra MCP server.
scan_opportunities 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 scan_opportunities 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 scan_opportunities. 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.
scan_opportunities 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.
