get_formula

THE RISK

Low Risk

Why get_formula needs a policy

This tool retrieves formula information and its computed value from Coda documents without creating, modifying, or deleting any data. It is a straightforward read operation with no side effects, making it low severity and fitting squarely in the Read category.

From the tool's definition Tool name is 'get_formula' and description states it 'Get details about a specific named formula including its computed value'. The verb 'get' and the phrasing 'details about' and 'including its computed value' indicate retrieval without modification.

POLICY

How to control get_formula

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_formula": {}
  }
}

get_formula is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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