What spine.list does on Pixi Inspector
AI agents call spine.list to retrieve information from Pixi Inspector without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
tabId | integer | — | Legacy: a bare tab id, resolved inside the browser this session is already working with. Prefer `target`, which is unambiguous across browsers. |
target | string | — | Drive a specific tab: a target id like "b7a3c1#487" from status/use_target/CHOOSE_TARGET. Omit to use this session's chosen tab (or the only available one). Pas |
frameId | integer | — | Escape hatch: drive a specific FRAME of the tab (0 is the top frame). Normally unnecessary — the extension picks the frame running the game (canvas owner first, |

Why spine.list is rated Low
Even though spine.list only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

The rule that runs spine.list safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Pixi Inspector, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For spine.list, this is the rule to start with:
spine.list 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 Pixi Inspector, apply this rule, and every spine.list call is checked against it from then on.

Register the Pixi Inspector MCP server in PolicyLayer and add a rule for spine.list: 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 Pixi Inspector. Nothing to install.
spine.list 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 spine.list 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 spine.list. 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.
spine.list is provided by the Pixi Inspector MCP server (pixi-inspector-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
