AI agents use submit_media_block to create or modify resources in PoolParty Main Stage Airtime. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call submit_media_block repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach PoolParty Main Stage Airtime.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access submit_media_block gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Submit a media block to a PoolParty channel community queue. Requires API key with submit:block scope. Requires a session token from create_join_session. Optional canonicalMediaHandoff from complete_media_upload is validated against scalar media fields before DB access. Response includes media provider/readiness, mintStatus, poolEligibility, and nextAction for both Livepeer and S3 fallback submits. Scalar-only submit remains supported but is labeled unverified fallback. Rate-limited per key. Pilot guidance: submit one high-quality block. Do not farm rewards. Wallet required for reward claims, not for submission.. It is categorised as a Write tool in the PoolParty Main Stage Airtime MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the PoolParty Main Stage Airtime MCP server in PolicyLayer and add a rule for submit_media_block: 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 PoolParty Main Stage Airtime. Nothing to install.
submit_media_block 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 submit_media_block 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 submit_media_block. 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.
submit_media_block is provided by the PoolParty Main Stage Airtime MCP server (https://www.poolparty.io/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
