AI agents call sync-analyse-video to retrieve information from Twelvelabs Mcp Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though sync-analyse-video only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access sync-analyse-video gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Synchronously analyse a video and return the generated text (or structured JSON) inline. Input sources (provide exactly one): - videoId — pre-indexed video. Pegasus 1.2 only (legacy, kept for backwards compatibility). - videoUrl / assetId / base64Video — direct sources (1.2.4+). Work with both Pegasus 1.2 and 1.5. Model selection (modelName): - pegasus1.2 (default, server-side) — general analysis; accepts videoId. - pegasus1.5 — adds clip windowing (startTime/endTime), structured prompts (promptV2 with image refs), and larger token budget. Does NOT accept videoId. Prompting: Either prompt (plain text, max 2000 tokens) or promptV2 (structured prompt with <@name> image references, Pegasus 1.5 only). Mutually exclusive. Structured JSON output: Set jsonSchema to constrain output to a JSON Schema (Draft 2020-12). Sync supports json_schema response_format only. Good for quick open-ended Q&A, summaries, chapters, highlights, or any prompt-guided text output. For videos over 1 hour or for time-based metadata segmentation, use async-analyse-video.. It is categorised as a Read tool in the Twelvelabs Mcp Server MCP Server, which means it retrieves data without modifying state.
Register the Twelvelabs Mcp Server MCP server in PolicyLayer and add a rule for sync-analyse-video: 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 Twelvelabs Mcp Server. Nothing to install.
sync-analyse-video 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 sync-analyse-video 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 sync-analyse-video. 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.
sync-analyse-video is provided by the Twelvelabs Mcp Server MCP server (https://mcp.twelvelabs.io). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
