Why ingest-files-from-paths needs a policy

This tool creates new document records in the Morphik database by importing files. It is reversible (documents can be deleted via delete-document) and has no external side effects beyond the database. It does not execute arbitrary code, delete data irreversibly, or move money. The blast radius is limited to database size and storage consumption.

From the tool's definition Tool name and description both indicate file ingestion: 'ingest-files-from-paths' and 'Add multiple files to Morphik'. The verb 'ingest' denotes data import and creation of records in the database.

POLICY

How to control ingest-files-from-paths

PolicyLayer is an MCP gateway — it sits between your AI agents and Morphik MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for ingest-files-from-paths:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ingest-files-from-paths": {
      "limits": [
        {
          "counter": "ingest-files-from-paths_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

ingest-files-from-paths stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about ingest-files-from-paths

What does the ingest-files-from-paths tool do? +

Add multiple files to Morphik. It is categorised as a Write tool in the Morphik MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on ingest-files-from-paths? +

Register the Morphik MCP server in PolicyLayer and add a rule for ingest-files-from-paths: 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 Morphik MCP. Nothing to install.

What risk level is ingest-files-from-paths? +

ingest-files-from-paths is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit ingest-files-from-paths? +

Yes. Add a rate_limit block to the ingest-files-from-paths 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 ingest-files-from-paths completely? +

Set action: deny in the PolicyLayer policy for ingest-files-from-paths. 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 ingest-files-from-paths? +

ingest-files-from-paths is provided by the Morphik MCP server (morphik-org/morphik-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Morphik MCP tool call.

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