WHAT IT DOES

What snow_kms_manage does on Serac

AI agents use snow_kms_manage to create or update resources in Serac, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Serac environment.

RISK

Why snow_kms_manage is rated Medium

While the tool includes read operations (list_modules, list_keys) and cryptographic operations (encrypt, decrypt), the presence of create_key and rotate_key that write to sys_kmf_key tables makes this fundamentally a Write category tool. The writes are reversible (new keys can be rotated out, old versions retained).

From the tool's definition Tool description states "create a new key under a KMF module (writes sys_kmf_key)" and "rotate_key — generate a new active version". Actions include create_key, rotate_key which modify KMF state.

RECOMMENDED RULE

The rule that runs snow_kms_manage safely

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

snow_kms_manage Rate-limited

snow_kms_manage 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.

FAQ

Questions about snow_kms_manage

What does the snow_kms_manage tool do? +

Unified tool for the ServiceNow Key Management Framework. Covers KMF modules (sys_kmf_module), cryptographic modules (sys_kmf_crypto_module), and keys (sys_kmf_key) for use in PII/PCI encryption flows and Edge Encryption. Actions: - list_modules — list KMF modules (sys_kmf_module) and their crypto modules - create_key — create a new key under a KMF module (writes sys_kmf_key) - encrypt — encrypt a plaintext payload using the named key - decrypt — decrypt a ciphertext payload using the named key - list_keys — list keys, optionally filtered by module - rotate_key — generate a new active version of a key and deactivate the previous one Use when: managing KMF modules and keys for sensitive data, rotating keys on schedule, or wrapping/unwrapping payloads through the platform. Encrypt and decrypt invoke a server-side helper Script Include rather than the Table API; falls back to a scripted-execution path if the dedicated endpoint is absent. Returns: action-specific data. List operations return arrays of KMF records (sys_id, name, module, type, active, key_format). Create/rotate return the new key record. Encrypt/decrypt return the wrapped/unwrapped payload as a string. Plaintext and ciphertext are never logged in error metadata. It is categorised as a Write tool in the Serac MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on snow_kms_manage? +

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

What risk level is snow_kms_manage? +

snow_kms_manage is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit snow_kms_manage? +

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

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

snow_kms_manage is provided by the Serac MCP server (serac-labs/serac). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
