arango_backup_graph

Backup a single named graph

Part of the Pypi:mcp Arangodb Async server.

arango_backup_graph is read-only, but an agent in a loop can still rack up calls and cost. PolicyLayer caps every call before it runs. Live in minutes.

AI agents call arango_backup_graph to retrieve information from Pypi:mcp Arangodb Async without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though arango_backup_graph only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so arango_backup_graph only ever does what you allow.

What does the arango_backup_graph tool do? +

Backup a single named graph. It is categorised as a Read tool in the Pypi:mcp Arangodb Async MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on arango_backup_graph? +

Register the Pypi:mcp Arangodb Async MCP server in PolicyLayer and add a rule for arango_backup_graph: 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 Pypi:mcp Arangodb Async. Nothing to install.

What risk level is arango_backup_graph? +

arango_backup_graph is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit arango_backup_graph? +

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

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

arango_backup_graph is provided by the Pypi:mcp Arangodb Async MCP server (PCfVW/mcp-arangodb-async). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Pypi:mcp Arangodb Async tool call.
