WHAT IT DOES

What add_rss_source does on Nodebench

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

RISK

Why add_rss_source is rated Medium

The tool creates and persists a new RSS feed source record in a SQLite database. This is a reversible write operation (the feed can be removed or updated later). There is no irreversible deletion (would be Destructive), no code execution (would be Execute), and no financial transaction. The activity is data creation/modification, fitting the Write category.

From the tool's definition "Register an RSS or Atom feed URL for monitoring. Stored in SQLite for persistent tracking." — this stores data (a feed URL) in a SQLite database, which is a create/write operation.

RECOMMENDED RULE

The rule that runs add_rss_source safely

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

add_rss_source Rate-limited

add_rss_source 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 Nodebench, apply this rule, and every add_rss_source call is checked against it from then on.

FAQ

Questions about add_rss_source

What does the add_rss_source tool do? +

Register an RSS or Atom feed URL for monitoring. Stored in SQLite for persistent tracking. Validates the feed on add. Use fetch_rss_feeds to pull articles and build_research_digest to generate a digest of new articles. It is categorised as a Write tool in the Nodebench MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_rss_source? +

Register the Nodebench MCP server in PolicyLayer and add a rule for add_rss_source: 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 Nodebench. Nothing to install.

What risk level is add_rss_source? +

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

Can I rate-limit add_rss_source? +

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

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

add_rss_source is provided by the Nodebench MCP server (nodebench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
