AI agents call openspec_get_progress_summary to retrieve information from OpenSpec MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays progress metrics and summaries across tracked changes. It performs no mutations, executions, deletions, or financial operations. The read-only nature and informational purpose place it firmly in the Read category with low severity, as it cannot cause side effects or harm if misused by an AI agent.
From the tool's definition Tool name 'openspec_get_progress_summary' and description 'Get progress summary for all changes' indicate a retrieval/query operation that fetches aggregated progress data without modifying or executing operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and OpenSpec MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for openspec_get_progress_summary:
{
"version": "1",
"default": "deny",
"tools": {
"openspec_get_progress_summary": {}
}
}openspec_get_progress_summary is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get progress summary for all changes. It is categorised as a Read tool in the OpenSpec MCP MCP Server, which means it retrieves data without modifying state.
Register the OpenSpec MCP server in PolicyLayer and add a rule for openspec_get_progress_summary: 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 OpenSpec MCP. Nothing to install.
openspec_get_progress_summary 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 openspec_get_progress_summary 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 openspec_get_progress_summary. 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.
openspec_get_progress_summary is provided by the OpenSpec MCP server (lumiaqian/openspec-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OpenSpec MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
