AI agents call search_snippets to retrieve information from PhonePi MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries snippet data based on search criteria without creating, modifying, deleting, or executing anything. It matches the 'Read' category definition of data retrieval with no side effects. Severity is low because disclosure of snippet contents poses minimal risk unless snippets contain highly sensitive data, but the tool itself cannot cause damage.
From the tool's definition Tool name 'search_snippets' and description 'Search snippets by query' indicate a retrieval operation with no side effects. Snippets are user-stored text data, and searching them is a read-only query operation.
Documented attack patterns abuse exactly the kind of access search_snippets gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PhonePi MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_snippets:
{
"version": "1",
"default": "deny",
"tools": {
"search_snippets": {}
}
}search_snippets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search snippets by query. It is categorised as a Read tool in the PhonePi MCP MCP Server, which means it retrieves data without modifying state.
Register the PhonePi MCP server in PolicyLayer and add a rule for search_snippets: 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 PhonePi MCP. Nothing to install.
search_snippets 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 search_snippets 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 search_snippets. 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.
search_snippets is provided by the PhonePi MCP server (priyankark/phonepi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
