What lookup_pypi does on GoCreative Agent API
AI agents call lookup_pypi to retrieve information from GoCreative Agent API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

pkg | string | Yes |
Parameters from the server's own tool schema.
Why lookup_pypi is rated Low
lookup_pypi retrieves public package metadata from PyPI, which is a read-only operation. There are no destructive, write, execute, or financial side effects beyond the stated micropayment (which is a standard billing mechanism, not a financial transaction initiated by the tool itself). The tool enables dependency research and license audits, both informational use cases.
From the tool's definition Tool description explicitly states 'Get PyPI package metadata (latest version, summary, author, dependencies)' — purely retrieval operations with no modification, deletion, or execution. Example call queries package info without side effects.
Attacks that exploit this kind of access
The rule that runs lookup_pypi safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GoCreative Agent API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For lookup_pypi, this is the rule to start with:
lookup_pypi is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect GoCreative Agent API, apply this rule, and every lookup_pypi call is checked against it from then on.

lookup_pypi accepts 1 parameter: pkg. Required: pkg. The full parameter table on this page comes from the server's own tool schema.
Register the GoCreative Agent API MCP server in PolicyLayer and add a rule for lookup_pypi: 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 GoCreative Agent API. Nothing to install.
lookup_pypi is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the lookup_pypi 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.
Set action: deny in the PolicyLayer policy for lookup_pypi. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
lookup_pypi is provided by the GoCreative Agent API MCP server (https://api.gocreativeai.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
