Confirm the completion of task planning and proceed to the execution phase
AI agents invoke spec_coding_tasks_confirmed to trigger actions in Spec-driven Development MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool transitions the workflow to the code execution phase. While the tool itself appears to be a confirmation/state-transition action, it enables the triggering of code execution operations ('spec_coding_execute_start') based on its position in the documented workflow pipeline. The actual code execution would occur next, making this tool a critical control point.
From the tool's definition Tool description states it 'proceed to the execution phase' after task planning confirmation. The server description explicitly mentions 'systematic code execution' as a final stage, and this tool serves as the gateway to that execution phase.
Documented attack patterns abuse exactly the kind of access spec_coding_tasks_confirmed gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Spec-driven Development MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for spec_coding_tasks_confirmed:
{
"version": "1",
"default": "deny",
"tools": {
"spec_coding_tasks_confirmed": {
"limits": [
{
"counter": "spec_coding_tasks_confirmed_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} spec_coding_tasks_confirmed stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Confirm the completion of task planning and proceed to the execution phase. It is categorised as a Execute tool in the Spec-driven Development MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Spec-driven Development MCP Server MCP server in PolicyLayer and add a rule for spec_coding_tasks_confirmed: 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 Spec-driven Development MCP Server. Nothing to install.
spec_coding_tasks_confirmed is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the spec_coding_tasks_confirmed 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 spec_coding_tasks_confirmed. 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.
spec_coding_tasks_confirmed is provided by the Spec-driven Development MCP Server MCP server (kevinlin/spec-coding-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Spec-driven Development MCP Server, 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.
