WHAT IT DOES

What context.create_packet does on Visionmcp

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

RISK

Why context.create_packet is rated Medium

The tool creates a new data structure (decision packet) as a reversible operation. This is a Write action since it generates new artifacts within the system without permanent deletion or execution of arbitrary code.

From the tool's definition Tool description states 'Create a compact component-local decision packet', using the verb 'create' which indicates data creation/modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs context.create_packet safely

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

context.create_packet Rate-limited

context.create_packet 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 Visionmcp, apply this rule, and every context.create_packet call is checked against it from then on.

How do I enforce a policy on context.create_packet? +

Register the Vision MCP server in PolicyLayer and add a rule for context.create_packet: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Visionmcp. Nothing to install.

What risk level is context.create_packet? +

Can I rate-limit context.create_packet? +

Yes. Add a rate_limit block to the context.create_packet rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block context.create_packet completely? +
