Part of the Commit — Supply Chain Risk Scoring server.

AI agents call lookup_go_module to retrieve information from Commit — Supply Chain Risk Scoring without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though lookup_go_module only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access lookup_go_module gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Get a behavioral commitment profile for any Go module on proxy.golang.org. Takes a full module path (e.g., "github.com/gin-gonic/gin", "golang.org/x/net", "k8s.io/client-go", "gopkg.in/yaml.v3") and returns real signals: module age, version count, publish cadence, GitHub contributors (the closest equivalent to "publishers" since Go has no centralized publisher concept — git push access is the publish equivalent), GitHub stars, OpenSSF Scorecard score. The Go ecosystem has no centralized download counter, so this profile is GitHub-primary — the linked source repository's activity, contributor count, and Scorecard carry more weight than for npm/PyPI/Cargo. Stars are used as the popularity proxy. Useful for: vetting Go dependencies before adding to go.mod, identifying abandonware, supply chain risk assessment. Examples: "github.com/gin-gonic/gin", "golang.org/x/crypto", "github.com/spf13/cobra", "k8s.io/api". It is categorised as a Read tool in the Commit — Supply Chain Risk Scoring MCP Server, which means it retrieves data without modifying state.
Register the Commit — Supply Chain Risk Scoring MCP server in PolicyLayer and add a rule for lookup_go_module: 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 Commit — Supply Chain Risk Scoring. Nothing to install.
lookup_go_module 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_go_module 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_go_module. 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_go_module is provided by the Commit — Supply Chain Risk Scoring MCP server (proof-of-commitment). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
