WHAT IT DOES

What sap_compact_inscribe_memory does on Sap

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

Parameter	Type	Required	Description
`nonce`	array	—	Encryption nonce as a byte array, hex string, or base64 string
`vaultPda`	string	—	Vault PDA (base58) for the memory inscription
`sessionPda`	string	—	Session PDA (base58) for the memory inscription
`contentHash`	array	—	32-byte content hash as a byte array, hex string, or base64 string
`encryptedData`	array	—	Encrypted memory data as a byte array, hex string, or base64 string

Parameters from the server's own tool schema.

RISK

Why sap_compact_inscribe_memory is rated Medium

Writes encrypted payloads or hashes to on-chain storage via blockchain inscription.

From the tool's definition compact memory inscription, store encrypted payloads, on-chain metadata

RECOMMENDED RULE

The rule that runs sap_compact_inscribe_memory safely

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

sap_compact_inscribe_memory Rate-limited

sap_compact_inscribe_memory 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.

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

FAQ

Questions about sap_compact_inscribe_memory

What does the sap_compact_inscribe_memory tool do? +

Compact memory inscription with explicit vault/session PDAs. SAP MCP context: Memory/session flow. Store only intentionally encrypted payloads or public hashes; session and vault PDAs are visible on-chain metadata. SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required. It is categorised as a Write tool in the Sap MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does sap_compact_inscribe_memory accept? +

sap_compact_inscribe_memory accepts 5 parameters: nonce, vaultPda, sessionPda, contentHash, encryptedData. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on sap_compact_inscribe_memory? +

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

What risk level is sap_compact_inscribe_memory? +

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

Can I rate-limit sap_compact_inscribe_memory? +

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

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

sap_compact_inscribe_memory is provided by the Sap MCP server (https://mcp.sap.oobeprotocol.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
