WHAT IT DOES

What extend_vesting does on Basis MCP Server

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

RISK

Why extend_vesting is rated Medium

Extending a vesting duration modifies an existing vesting schedule's parameters (reversibly in the sense that vesting can be further modified, though the extension itself may lock tokens longer). This is a Write operation as it updates/modifies existing data rather than deleting or executing arbitrary code.

RECOMMENDED RULE

The rule that runs extend_vesting safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Basis MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For extend_vesting, this is the rule to start with:

extend_vesting Rate-limited

extend_vesting 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.
