WHAT IT DOES

What add_attachment does on FeatureBoard

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

RISK

Why add_attachment is rated Medium

This tool creates or modifies ticket metadata by attaching files/URLs. It is reversible (attachments can be removed) and does not delete data or execute arbitrary code. It fits the Write category: a creation/modification action with side effects limited to data state changes.

From the tool's definition Tool description states it 'Attach[es] a file path or URL to a ticket' and stores metadata on the ticket line. The idempotent behavior confirms it modifies ticket state (adds or updates the Attachments field).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_attachment safely

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

add_attachment Rate-limited

add_attachment 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 FeatureBoard, apply this rule, and every add_attachment call is checked against it from then on.

FAQ

Questions about add_attachment

What does the add_attachment tool do? +

Attach a file path or URL to a ticket (stored as [Attachments: ...] on the ticket line). Idempotent: attaching the same item twice is a no-op. It is categorised as a Write tool in the FeatureBoard 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_attachment? +

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

What risk level is add_attachment? +

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

Can I rate-limit add_attachment? +

Yes. Add a rate_limit block to the add_attachment 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_attachment completely? +

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

add_attachment is provided by the FeatureBoard MCP server (https://github.com/valentil/featureboard-mcp/releases/download/v0.7/featureboard.plugin). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
