WHAT IT DOES

What cookie_set does on Mcp Anything

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

RISK

Why cookie_set is rated Medium

Cookie setting creates or modifies browser/application state reversibly. This is a Write operation - it changes data but is not permanent (cookies can be cleared/modified). Severity is medium because cookie manipulation could affect authentication, tracking, or session state, but the impact depends on context and the specific cookies being set.

From the tool's definition Tool name 'cookie_set' indicates modification of cookie data. Description is empty, limiting certainty.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs cookie_set safely

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

cookie_set Rate-limited

cookie_set 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Anything, apply this rule, and every cookie_set call is checked against it from then on.
