WHAT IT DOES

What adb_file_checksum does on Deepadb

AI agents call adb_file_checksum to retrieve information from Deepadb without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why adb_file_checksum is rated Low

This is a read-only operation that queries file metadata (hash and size) without creating, modifying, executing, deleting, or moving data. While it accesses device files, it performs no side effects and merely reports computed values. The low severity reflects minimal blast radius—misuse would at worst allow an agent to verify file integrity, which poses no harm to the device or data.

From the tool's definition "Compute SHA-256 hash of a file on the device" and "Read-only operation. Reports file size alongside the hash." The tool retrieves and computes a digest of existing data without modification.

RECOMMENDED RULE

The rule that runs adb_file_checksum safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Deepadb, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For adb_file_checksum, this is the rule to start with:

adb_file_checksum Allowed

adb_file_checksum is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Deepadb, apply this rule, and every adb_file_checksum call is checked against it from then on.

FAQ

Questions about adb_file_checksum

What does the adb_file_checksum tool do? +

Compute SHA-256 hash of a file on the device. Critical for firmware integrity verification, tamper detection, and comparing files across devices. Read-only operation. Reports file size alongside the hash. It is categorised as a Read tool in the Deepadb MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on adb_file_checksum? +

Register the Deepadb MCP server in PolicyLayer and add a rule for adb_file_checksum: 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 Deepadb. Nothing to install.

What risk level is adb_file_checksum? +

adb_file_checksum is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit adb_file_checksum? +

Yes. Add a rate_limit block to the adb_file_checksum 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 adb_file_checksum completely? +

Set action: deny in the PolicyLayer policy for adb_file_checksum. 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 adb_file_checksum? +

adb_file_checksum is provided by the Deepadb MCP server (deepadb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
