AI agents call get_model_fields to retrieve information from Odoo MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves schema/metadata information about Odoo model fields. It performs a read-only query operation with no side effects, no code execution, and no data modification. The blast radius of misuse is minimal—an attacker gains only structural knowledge of the database schema, which is non-sensitive compared to actual data access or destructive operations. Classification as Read is appropriate.
From the tool's definition Tool name 'get_model_fields' and description 'Get field definitions for a model' indicate a retrieval operation that queries metadata about model structure without modifying or deleting data.
Documented attack patterns abuse exactly the kind of access get_model_fields gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Odoo MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_model_fields:
{
"version": "1",
"default": "deny",
"tools": {
"get_model_fields": {}
}
}get_model_fields is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get field definitions for a model. It is categorised as a Read tool in the Odoo MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Odoo MCP Server MCP server in PolicyLayer and add a rule for get_model_fields: 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 Odoo MCP Server. Nothing to install.
get_model_fields 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_model_fields 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_model_fields. 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_model_fields is provided by the Odoo MCP Server MCP server (vzeman/odoo-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Odoo MCP Server, 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.
