Medium Risk

create_namespace

Create a new namespace in an S3 table bucket. Creates a namespace. A namespace is a logical grouping of tables within your S3 table bucket, which you can use to organize S3 tables. Permissions: You must have the s3tables:CreateNamespace permission to use this operation.

Part of the AWS S3 Tables MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents use create_namespace to create or modify resources in AWS S3 Tables MCP Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call create_namespace repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach AWS S3 Tables MCP Server.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the create_namespace tool do? +

Create a new namespace in an S3 table bucket. Creates a namespace. A namespace is a logical grouping of tables within your S3 table bucket, which you can use to organize S3 tables. Permissions: You must have the s3tables:CreateNamespace permission to use this operation.. It is categorised as a Write tool in the AWS S3 Tables MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_namespace? +

Add a rule in your Intercept YAML policy under the tools section for create_namespace. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS S3 Tables MCP Server MCP server.

What risk level is create_namespace? +

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

Can I rate-limit create_namespace? +

Yes. Add a rate_limit block to the create_namespace rule in your Intercept 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 create_namespace completely? +

Set action: deny in the Intercept policy for create_namespace. 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 create_namespace? +

create_namespace is provided by the AWS S3 Tables MCP Server MCP server (awslabs.s3-tables-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
