Get metadata for a specific RGB asset
AI agents call rgb_get_asset_metadata to retrieve information from RGB Lightning Network MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves asset metadata without modifying, deleting, or executing operations. It is a read-only query similar to 'get' or 'fetch' operations. The blast radius is minimal since it only returns information about an asset's metadata. No financial transactions, code execution, or data modification occurs.
From the tool's definition Tool name 'rgb_get_asset_metadata' and description 'Get metadata for a specific RGB asset' indicate a retrieval/query operation with no side effects.

Register the RGB Lightning Network MCP Server MCP server in PolicyLayer and add a rule for rgb_get_asset_metadata: 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 RGB Lightning Network MCP Server. Nothing to install.
rgb_get_asset_metadata 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 rgb_get_asset_metadata 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 rgb_get_asset_metadata. 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.
rgb_get_asset_metadata is provided by the RGB Lightning Network MCP Server MCP server (lnfi-network/rgb-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
