Get the current block number on Monad Testnet
AI agents call get_block_number to retrieve information from Monad MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a single piece of data (current block number) from the testnet without modifying, executing, or deleting anything. It has no external side effects and presents minimal risk if misused by an AI agent.
From the tool's definition Tool name 'get_block_number' and description 'Get the current block number on Monad Testnet' indicate a simple read operation that retrieves immutable blockchain state without side effects.

Register the Monad MCP Server MCP server in PolicyLayer and add a rule for get_block_number: 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 Monad MCP Server. Nothing to install.
get_block_number 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_block_number 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 get_block_number. 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_block_number is provided by the Monad MCP Server MCP server (tairon-ai/monad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
