What serac_store does on Serac
AI agents use serac_store 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.
Why serac_store is rated Medium
This tool writes (uploads) base64-encoded, client-side encrypted data to a remote storage namespace. It creates new objects in the store but does not delete, execute code, or move money. Misuse could lead to storing malicious or unauthorized data in the namespace, but effects are reversible (data can be deleted).
From the tool's definition 'Store encrypted data in an isolated namespace' — creates/uploads new data to cloud storage
Attacks that exploit this kind of access
The rule that runs serac_store 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 serac_store, this is the rule to start with:
serac_store 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 Serac, apply this rule, and every serac_store call is checked against it from then on.

Register the Serac MCP server in PolicyLayer and add a rule for serac_store: 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.
serac_store is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the serac_store 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.
Set action: deny in the PolicyLayer policy for serac_store. 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.
