gigaspec-generate · Gigaspec MCP: Risk & Policy

WHAT IT DOES

What gigaspec-generate does on Gigaspec

AI agents use gigaspec-generate to create or update resources in Gigaspec — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gigaspec environment.

WHY IT NEEDS A POLICY

Why gigaspec-generate needs a policy

This tool creates new specification documentation files based on configuration. While the operation is reversible (files can be deleted), it modifies the filesystem by generating multiple documentation artifacts. This makes it a Write operation rather than Read (which would only retrieve data).

From the tool's definition Tool description states it 'Creates all documentation files (AGENT.md, ARCHITECTURE.md, PLAN.md, etc.)', which are write operations that generate and create files in the filesystem.

Verdict

gigaspec-generate Rate-limited

gigaspec-generate 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.

Generate specification files from a configuration. Creates all documentation files (AGENT.md, ARCHITECTURE.md, PLAN.md, etc.) based on provided or loaded config. It is categorised as a Write tool in the Gigaspec MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on gigaspec-generate? +

Register the Gigaspec MCP server in PolicyLayer and add a rule for gigaspec-generate: 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 Gigaspec. Nothing to install.

What risk level is gigaspec-generate? +

gigaspec-generate is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit gigaspec-generate? +

Yes. Add a rate_limit block to the gigaspec-generate 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.

How do I block gigaspec-generate completely? +

Set action: deny in the PolicyLayer policy for gigaspec-generate. 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.

What MCP server provides gigaspec-generate? +

gigaspec-generate is provided by the Gigaspec MCP server (oleksiitrembach/gigaspec). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
