WHAT IT DOES

What crc32 does on Gateway

AI agents call crc32 to retrieve information from Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`text`	string	Yes	Text to checksum
`algorithm`	string	—	Algorithm

Parameters from the server's own tool schema.

RISK

Why crc32 is rated Low

This is a stateless cryptographic hash function. It retrieves (computes) data with no ability to modify, delete, execute commands, or trigger external systems. The blast radius of misuse is negligible: an adversary could only generate checksums, which are non-sensitive outputs and cannot be reverse-engineered to recover input in practice.

From the tool's definition Tool computes checksums (CRC-32 or Adler-32) for text strings. No side effects, no data modification, no external operations—purely a mathematical computation that returns a hash value.

RECOMMENDED RULE

The rule that runs crc32 safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For crc32, this is the rule to start with:

crc32 Allowed

crc32 is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "crc32": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Gateway, apply this rule, and every crc32 call is checked against it from then on.

FAQ

Questions about crc32

What does the crc32 tool do? +

CRC-32 / Adler-32 Checksum — Compute a CRC-32 or Adler-32 checksum for an arbitrary text string. It is categorised as a Read tool in the Gateway MCP Server, which means it retrieves data without modifying state.

What parameters does crc32 accept? +

crc32 accepts 2 parameters: text, algorithm. Required: text. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on crc32? +

Register the Gateway MCP server in PolicyLayer and add a rule for crc32: 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 Gateway. Nothing to install.

What risk level is crc32? +

crc32 is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit crc32? +

Yes. Add a rate_limit block to the crc32 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 crc32 completely? +

Set action: deny in the PolicyLayer policy for crc32. 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 crc32? +

crc32 is provided by the Gateway MCP server (https://wingmanprotocol.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
