Build the transaction steps to stake vault tokens into a timelock contract for boosted rewards. Returns an approve step (if needed) and a stake step.
Part of the Atv MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke build_stake_tx to trigger processes or run actions in Atv. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
build_stake_tx can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Build the transaction steps to stake vault tokens into a timelock contract for boosted rewards. Returns an approve step (if needed) and a stake step.. It is categorised as a Execute tool in the Atv MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for build_stake_tx. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Atv MCP server.
build_stake_tx is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the build_stake_tx 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 build_stake_tx. 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.
build_stake_tx is provided by the Atv MCP server (aarna-ai/atv). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
