WHAT IT DOES

What scb.tables.metadata does on Apibase

AI agents use scb.tables.metadata to create or update resources in Apibase, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Apibase environment.

Parameter	Type	Required	Description
`table_path`	string	Yes	Full path to a leaf table (type='t' from scb.catalog), e.g. 'BE/BE0101/BE0101A/BefolkningNy' (Sweden population by region/age/sex/year). 'AM/AKU/AKU01/AKU01A' (

Parameters from the server's own tool schema.

RISK

Why scb.tables.metadata is rated Medium

An AI agent can call scb.tables.metadata faster than any human can review: one bad instruction and it creates or modifies resources in Apibase by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs scb.tables.metadata safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For scb.tables.metadata, this is the rule to start with:

scb.tables.metadata Rate-limited

scb.tables.metadata 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 scb.tables.metadata

What does the scb.tables.metadata tool do? +

Get metadata for a specific SCB statistical table — title, dimensions (variables like Region, Alder/age, Kon/sex, Tid/year), valid value codes for each dimension, and latest update timestamp. Use this BEFORE scb.table_query to discover what filter values are accepted. Example path: 'BE/BE0101/BE0101A/BefolkningNy' (Sweden population by region/age/sex/year). It is categorised as a Write tool in the Apibase MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does scb.tables.metadata accept? +

scb.tables.metadata accepts 1 parameter: table_path. Required: table_path. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on scb.tables.metadata? +

Register the Apibase MCP server in PolicyLayer and add a rule for scb.tables.metadata: 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 Apibase. Nothing to install.

What risk level is scb.tables.metadata? +

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

Can I rate-limit scb.tables.metadata? +

Yes. Add a rate_limit block to the scb.tables.metadata 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 scb.tables.metadata completely? +

Set action: deny in the PolicyLayer policy for scb.tables.metadata. 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 scb.tables.metadata? +

scb.tables.metadata is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
