AI agents call sp_projects to retrieve information from Stitch Pro without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only retrieval of project information. It queries existing data from the Stitch account and returns a list with no ability to create, modify, delete, or execute operations. The action is passive information retrieval, fitting the 'Read' category with low severity since listing projects poses minimal risk—it exposes metadata but does not alter state or trigger external actions.
From the tool's definition Tool name 'sp_projects' and description 'List all projects in your Stitch account' indicate a query operation that retrieves project metadata without modification or side effects.
Documented attack patterns abuse exactly the kind of access sp_projects gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Stitch Pro, and nothing reaches the server without passing your rules. This is the rule we recommend for sp_projects:
{
"version": "1",
"default": "deny",
"tools": {
"sp_projects": {}
}
}sp_projects is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all projects in your Stitch account. It is categorised as a Read tool in the Stitch Pro MCP Server, which means it retrieves data without modifying state.
Register the Stitch Pro MCP server in PolicyLayer and add a rule for sp_projects: 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 Stitch Pro. Nothing to install.
sp_projects 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 sp_projects 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 sp_projects. 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.
sp_projects is provided by the Stitch Pro MCP server (luciferdono/stitch-pro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Stitch Pro, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
