batch_send_osc · MCP2OSC MCP: Risk & Policy

WHAT IT DOES

What batch_send_osc does on MCP2OSC

AI agents use batch_send_osc to create or update resources in MCP2OSC — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP2OSC environment.

WHY IT NEEDS A POLICY

Why batch_send_osc needs a policy

An AI agent can call batch_send_osc faster than any human can review — one bad instruction and it creates or modifies resources in MCP2OSC by the hundred, each call as confident as the last.

Verdict

batch_send_osc Rate-limited

batch_send_osc 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.

FAQ

Questions about batch_send_osc

What does the batch_send_osc tool do? +

Send multiple OSC messages in a single batch to a specified application or device for efficient real-time control. It is categorised as a Write tool in the MCP2OSC MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on batch_send_osc? +

Register the MCP2OSC MCP server in PolicyLayer and add a rule for batch_send_osc: 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 MCP2OSC. Nothing to install.

What risk level is batch_send_osc? +

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

Can I rate-limit batch_send_osc? +

Yes. Add a rate_limit block to the batch_send_osc 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 batch_send_osc completely? +

Set action: deny in the PolicyLayer policy for batch_send_osc. 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 batch_send_osc? +

batch_send_osc is provided by the MCP2OSC MCP server (yyf/mcp2osc). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
