Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs sap_update_tool 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_update_tool, this is the rule to start with:

sap_update_tool Rate-limited

sap_update_tool 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 sap_update_tool

What does the sap_update_tool tool do? +

Update tool descriptor hashes using SDK ToolsModule.update. SAP MCP context: Use tool registry writes to advertise concrete capabilities that this MCP can serve, including AgentKit bridge tools such as bridging_bridgeWormhole and Metaplex tools such as metaplex-nft_mintNFT. Publish only schemas and descriptions that match the actual MCP tool surface. SAP MCP execution guidance: Intent: local-signer write workflow. Pricing: paid value-action; preview cost and transaction effects before user confirmation. Routing: hosted accountless write is blocked; do not call this as a paid hosted write and no x402 payment should be charged. Use the local sap_payments bridge or a hosted unsigned builder when user signing is required. Signer boundary: user-controlled local profile or external signer; OOBE hosted MCP remains non-custodial. 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.

How do I enforce a policy on sap_update_tool? +

Register the Sap MCP server in PolicyLayer and add a rule for sap_update_tool: 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_update_tool? +

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

Can I rate-limit sap_update_tool? +

Yes. Add a rate_limit block to the sap_update_tool 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_update_tool completely? +

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