What append_scratchpad does on FeatureBoard
AI agents use append_scratchpad 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.
Why append_scratchpad is rated Medium
The tool creates or modifies data (appends to a scratchpad) without permanently destroying information. Appending is a write operation typical of a project board where notes and scratch work are tracked. The impact is low because scratchpad entries are non-critical working notes in a local project management context and can be easily corrected or removed.
From the tool's definition append_scratchpad appends/modifies a scratchpad on a board; this is a reversible write operation (content can be edited or deleted later).
Attacks that exploit this kind of access
The rule that runs append_scratchpad 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 append_scratchpad, this is the rule to start with:
append_scratchpad 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 append_scratchpad call is checked against it from then on.
Questions about append_scratchpad
Append a line or block to a board. 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.
Register the FeatureBoard MCP server in PolicyLayer and add a rule for append_scratchpad: 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.
append_scratchpad is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the append_scratchpad 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.
Set action: deny in the PolicyLayer policy for append_scratchpad. 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.
append_scratchpad 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.
