WHAT IT DOES

What drive_share does on Mcp

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

Parameter	Type	Required	Description
`ttl`	string	—	Lifetime, e.g. 1h, 7d (omit for no expiry)
`drive`	string	Yes	Drive name or drv_… id
`label`	string	—	Human label for the token
`perms`	string	—	read (default) or write
`pathPrefix`	string	—	Restrict the token to this path prefix

Parameters from the server's own tool schema.

RISK

Why drive_share is rated Medium

This tool creates (mints) new security credentials that grant another agent read or write access to a drive. While not destructive, it modifies the access control state by issuing a new token with specific permissions.

From the tool's definition Tool description: 'Mint a scoped drive access token for another agent (perms read|write, optional path prefix + TTL like `7d`). The secret is returned ONCE.' — creates and returns access credentials.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs drive_share safely

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

drive_share Rate-limited

drive_share 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.
