What build_semantic_index does on Cutpilot
AI agents use build_semantic_index to create or update resources in Cutpilot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cutpilot environment.
Why build_semantic_index is rated Medium
The tool builds and persists (writes) a semantic index to storage. It does not delete existing data, execute arbitrary code, or involve financial transactions. The index creation is reversible (it can be rebuilt or deleted), making Write the appropriate category. Medium severity because misuse could corrupt or overwrite an existing index, impacting the project's asset discoverability.
From the tool's definition "Build and persist a project-wide semantic index" — creates and stores a new index artifact
Attacks that exploit this kind of access
The rule that runs build_semantic_index safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cutpilot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For build_semantic_index, this is the rule to start with:
build_semantic_index 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Cutpilot, apply this rule, and every build_semantic_index call is checked against it from then on.
Questions about build_semantic_index
Build and persist a project-wide semantic index covering assets, exact subclip ranges, transcript cues, tags, and local visual intelligence. It is categorised as a Write tool in the Cutpilot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Cutpilot MCP server in PolicyLayer and add a rule for build_semantic_index: 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 Cutpilot. Nothing to install.
build_semantic_index is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the build_semantic_index 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 build_semantic_index. 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.
build_semantic_index is provided by the Cutpilot MCP server (Hellotravisss/cutpilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
