Why download_filing needs a policy

Downloading a filing is a read-only operation with no side effects—it does not modify, delete, or execute anything. The data retrieved is non-sensitive public information already disclosed to the market.

From the tool's definition Tool name 'download_filing' and description 'Download a specific SEC filing document' indicate retrieval of publicly available SEC EDGAR data with no modification, deletion, or execution of code.

POLICY

How to control download_filing

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

policy.json

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

download_filing 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 SEC MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
