Why oca_link needs a policy

Creating a symlink in the Odoo addons path is a filesystem operation that affects the server's module loading behavior. It's not purely a write (data creation) but an execution-level action that modifies the runtime environment — adding a symlink to the addons path causes Odoo to discover and potentially load new modules, which can alter system behavior.

POLICY

How to control oca_link

PolicyLayer is an MCP gateway — it sits between your AI agents and Odoo Claude MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for oca_link:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "oca_link": {
      "limits": [
        {
          "counter": "oca_link_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

oca_link stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Odoo Claude MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about oca_link

What does the oca_link tool do? +

Create symlink for OCA addon module in the Odoo addons path. It is categorised as a Execute tool in the Odoo Claude MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on oca_link? +

Register the Odoo Claude MCP server in PolicyLayer and add a rule for oca_link: 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 Claude MCP. Nothing to install.

What risk level is oca_link? +

oca_link is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit oca_link? +

Yes. Add a rate_limit block to the oca_link 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.

How do I block oca_link completely? +

Set action: deny in the PolicyLayer policy for oca_link. 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.

What MCP server provides oca_link? +

oca_link is provided by the Odoo Claude MCP server (rosenvladimirov/odoo-claude-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Odoo Claude MCP tool call.

Start from Odoo Claude MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
