AI agents call mindyield_vaults_list to retrieve information from Agent Einstein — Autonomous Crypto Intelligence 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 mindyield_vaults_list 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.

MindYield Yield Prediction Markets: List active MindYield yield prediction markets (ProbabilityVaultV2). Returns each vault with TVL, YES/NO ratio (live implied probability), time-to-resolution, and the underlying Polymarket conditionId. No-loss: only the generated yield is at stake; principal is always returned. Note: yield prediction markets are the canonical product — Mirror Contests are deprecated and not listed.. It is categorised as a Read tool in the Agent Einstein — Autonomous Crypto Intelligence MCP Server, which means it retrieves data without modifying state.
Register the Agent Einstein — Autonomous Crypto Intelligence MCP server in PolicyLayer and add a rule for mindyield_vaults_list: 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 Agent Einstein — Autonomous Crypto Intelligence. Nothing to install.
mindyield_vaults_list 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 mindyield_vaults_list 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 mindyield_vaults_list. 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.
mindyield_vaults_list is provided by the Agent Einstein — Autonomous Crypto Intelligence MCP server (https://emc2ai.io/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
