Get the dropdown values for a specific code. Use list_system_codes() first to find the code ID.
AI agents call get_code_values to retrieve information from Mcp Mifosx without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves reference/dropdown data (code values) from the banking system without creating, modifying, or deleting any financial records or executing transactions. It is a simple data query operation with no side effects, fitting the Read category. Severity is low because misuse cannot cause financial harm or data loss—at worst, an agent might retrieve unnecessary reference data.
From the tool's definition Tool name 'get_code_values' and description 'Get the dropdown values for a specific code' indicate data retrieval with no modification or side effects. The instruction to 'Use list_system_codes() first' confirms a lookup/query pattern.
Documented attack patterns abuse exactly the kind of access get_code_values gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Mifosx, and nothing reaches the server without passing your rules. This is the rule we recommend for get_code_values:
{
"version": "1",
"default": "deny",
"tools": {
"get_code_values": {}
}
}get_code_values is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the dropdown values for a specific code. Use list_system_codes() first to find the code ID. It is categorised as a Read tool in the Mcp Mifosx MCP Server, which means it retrieves data without modifying state.
Register the Mcp Mifosx MCP server in PolicyLayer and add a rule for get_code_values: 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 Mcp Mifosx. Nothing to install.
get_code_values 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_code_values 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_code_values. 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_code_values is provided by the Mcp Mifosx MCP server (openmf/mcp-mifosx). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Mifosx, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
