Compares specification requirements against implementation files and returns a drift report showing which requirements are implemented and which are missing.
AI agents call sdd_check_sync to retrieve information from Specky without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a comparison analysis between specification documents and implementation code, producing a report. This is fundamentally a read operation—it queries and analyzes existing data structures to identify gaps and status. There are no side effects, data modifications, destructive operations, or financial implications. The operation is purely informational and reversible, fitting the Read category.
From the tool's definition The tool 'compares specification requirements against implementation files and returns a drift report showing which requirements are implemented and which are missing.' This is a read-only query operation that retrieves and compares data without modifying…
Documented attack patterns abuse exactly the kind of access sdd_check_sync gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Specky, and nothing reaches the server without passing your rules. This is the rule we recommend for sdd_check_sync:
{
"version": "1",
"default": "deny",
"tools": {
"sdd_check_sync": {}
}
}sdd_check_sync is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Compares specification requirements against implementation files and returns a drift report showing which requirements are implemented and which are missing. It is categorised as a Read tool in the Specky MCP Server, which means it retrieves data without modifying state.
Register the Specky MCP server in PolicyLayer and add a rule for sdd_check_sync: 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 Specky. Nothing to install.
sdd_check_sync 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 sdd_check_sync 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 sdd_check_sync. 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.
sdd_check_sync is provided by the Specky MCP server (paulasilvatech/specky). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Specky, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
