Get all script diffs currently staged and awaiting review in the Linkedsword plugin. Shows diff summaries with hunk counts, addition/removal stats, and status. Returns: Array of pending diffs with summaries. Empty array if no diffs are pending.
AI agents call get_diff_queue to retrieve information from Melo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and displays pending script diffs for review purposes. It performs only a read operation to retrieve and display information about diffs that exist in the plugin's queue. No creation, modification, deletion, or execution of code occurs.
From the tool's definition Tool description explicitly states 'Get all script diffs currently staged' and 'Shows diff summaries' — these are retrieval operations with no modifications. Returns data only: 'Array of pending diffs with summaries.

Get all script diffs currently staged and awaiting review in the Linkedsword plugin. Shows diff summaries with hunk counts, addition/removal stats, and status. Returns: Array of pending diffs with summaries. Empty array if no diffs are pending. It is categorised as a Read tool in the Melo MCP Server, which means it retrieves data without modifying state.
Register the Melo MCP server in PolicyLayer and add a rule for get_diff_queue: 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 Melo. Nothing to install.
get_diff_queue is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_diff_queue 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 get_diff_queue. 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.
get_diff_queue is provided by the Melo MCP server (yannyhl/linkedsword-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
