What create_snapshot does on 20i MCP Server
AI agents use create_snapshot to create or update resources in 20i MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 20i MCP Server environment.
Why create_snapshot is rated Medium
This tool creates a backup/snapshot artifact, which is a Write operation. Severity is high because snapshots of databases and web files can consume significant storage resources, potentially affect system performance, and could be misused to exfiltrate sensitive data if combined with other tools.
From the tool's definition Tool description states 'Create immediate snapshot of web files or database' — this creates a new data object (snapshot) that captures application state. The action is reversible (snapshots can be deleted) and does not permanently remove or move data.
Attacks that exploit this kind of access
The rule that runs create_snapshot safely
PolicyLayer is an MCP gateway: it sits between your AI agents and 20i MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_snapshot, this is the rule to start with:
create_snapshot 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 20i MCP Server, apply this rule, and every create_snapshot call is checked against it from then on.
Questions about create_snapshot
Create immediate snapshot of web files or database. It is categorised as a Write tool in the 20i MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the 20i MCP Server MCP server in PolicyLayer and add a rule for create_snapshot: 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 20i MCP Server. Nothing to install.
create_snapshot 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 create_snapshot 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 create_snapshot. 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.
create_snapshot is provided by the 20i MCP Server MCP server (cbrown35/20i-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
