What gha_workflow_lint does on ScorpTech x402 API
AI agents invoke gha_workflow_lint to trigger actions in ScorpTech x402 API. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
workflow | string | Yes | Workflow file content (.github/workflows/*.yml) |
Parameters from the server's own tool schema.
Why gha_workflow_lint is rated High
gha_workflow_lint triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Attacks that exploit this kind of access
The rule that runs gha_workflow_lint safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gha_workflow_lint, this is the rule to start with:
gha_workflow_lint stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every gha_workflow_lint call is checked against it from then on.
Questions about gha_workflow_lint
Security audit of a GitHub Actions workflow YAML (zizmor / actionlint style): pwn-request checkouts under pull_request_target / workflow_run, script injection from attacker-controlled ${{ github.event.* }} contexts in run: and github-script, actions not pinned to a commit SHA, missing or write-all permissions, toJSON(secrets), secrets in workflow-wide env, self-hosted runners on PR triggers, persisted checkout credentials, disabled ::set-env / ::add-path commands, curl | bash, cache poisoning in release workflows, artifact poisoning, spoofable bot-actor conditions and hard-coded credentials. Findings carry line numbers, severity and the fix. Price: $0.003 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/gha-workflow-lint. It is categorised as a Execute tool in the ScorpTech x402 API MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
gha_workflow_lint accepts 1 parameter: workflow. Required: workflow. The full parameter table on this page comes from the server's own tool schema.
Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for gha_workflow_lint: 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 ScorpTech x402 API. Nothing to install.
gha_workflow_lint is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the gha_workflow_lint 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 gha_workflow_lint. 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.
gha_workflow_lint is provided by the ScorpTech x402 API MCP server (https://scorptech.it.com/api/x402/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
