Get a provider by ID
AI agents call get_provider to retrieve information from UseGrant MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query operation that fetches data about a provider based on its ID. It does not create, modify, delete, or execute any code. The blast radius from misuse is minimal—an attacker could only access information about providers already in the system.
From the tool's definition Tool name is 'get_provider' and description states 'Get a provider by ID' — a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get a provider by ID. It is categorised as a Read tool in the UseGrant MCP Server MCP Server, which means it retrieves data without modifying state.
Register the UseGrant MCP Server MCP server in PolicyLayer and add a rule for get_provider: 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 UseGrant MCP Server. Nothing to install.
get_provider 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 get_provider 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 get_provider. 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.
get_provider is provided by the UseGrant MCP Server MCP server (usegranthq/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
