create-contract · Openfort MCP Server MCP: Risk & Policy

WHAT IT DOES

What create-contract does on Openfort MCP Server

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

WHY IT NEEDS A POLICY

Why create-contract needs a policy

This tool creates (writes) a new smart contract resource in the Openfort wallet infrastructure project. While smart contracts can have financial implications, the tool itself performs a reversible creation/configuration action (the contract can be modified or potentially removed via sibling tools like delete-contract).

From the tool's definition Tool name 'create-contract' and description 'Creates a new smart contract in the project' indicate data creation. The tool adds a new smart contract resource to the project configuration.

create-contract Rate-limited

create-contract 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.
