AI agents use model_metavault_strategy to create or modify resources in Spectra. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call model_metavault_strategy repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Spectra.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Model a MetaVault "double loop" strategy for curators. MetaVaults are ERC-7540 curated vaults that automate LP rollover and compound YT yield back into LP positions. This tool models the economics of leveraging MetaVault shares as collateral on Morpho (or similar lending markets). Two modes: 1. Live mode: Provide chain + metavault_address to auto-populate base_apy from the live MetaVault API. All other params can be overridden. 2. Manual mode: Provide base_apy directly for hypothetical modeling. The "double loop": Layer 1 (inside vault): YT yield → LP tokens (compounding loop, managed by curator) Layer 2 (on top): MV shares → Morpho collateral → borrow → deposit back (leverage loop) Because YT compounding raises the base yield, leverage multiplies a higher base — creating a "double loop premium" over raw PT looping. Dual Morpho Market Strategy: Curators should create TWO Morpho markets for maximum flywheel effect: Market A (PT / underlying): For external users to loop PT. Drives pool volume & LP fees. Market B (MV shares / underlying): For the curator to loop vault shares. Amplifies own capital. These markets reinforce each other — PT demand deepens the pool, deeper pool attracts more loopers, and the curator earns fees on all external deposits flowing through the vault. Curator economics: The curator EARNS the performance fee on external deposits — this is revenue for managing the vault (rolling positions, compounding YT, maintaining allocations).. It is categorised as a Write tool in the Spectra MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Spectra MCP server in PolicyLayer and add a rule for model_metavault_strategy: 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 Spectra. Nothing to install.
model_metavault_strategy is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the model_metavault_strategy 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 model_metavault_strategy. 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.
model_metavault_strategy is provided by the Spectra MCP server (spectra-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
