create-offer · Phoenixd MCP Server MCP: Risk & Policy

WHAT IT DOES

What create-offer does on Phoenixd MCP Server

AI agents use create-offer to create or update resources in Phoenixd MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Phoenixd MCP Server environment.

WHY IT NEEDS A POLICY

Why create-offer needs a policy

Creating a BOLT12 offer generates a reusable payment request that others can use to send funds. It creates a new artifact in the wallet system but does not itself move money — actual payments only occur when someone pays the offer. This is a Write operation (creating a new data object), though it has indirect financial implications if misused (e.g., creating offers with incorrect amounts).

create-offer Rate-limited

create-offer stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
