switch-chain · MCPilot MCP: Risk & Policy

WHAT IT DOES

What switch-chain does on MCPilot

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

WHY IT NEEDS A POLICY

Why switch-chain needs a policy

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

Verdict

switch-chain Rate-limited

switch-chain 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches MCPilot, so you can run agents against it safely.

FAQ

Questions about switch-chain

What does the switch-chain tool do? +

Switch the target chain. It is categorised as a Write tool in the MCPilot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on switch-chain? +

Register the MCPilot MCP server in PolicyLayer and add a rule for switch-chain: 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 MCPilot. Nothing to install.

What risk level is switch-chain? +

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

Can I rate-limit switch-chain? +

Yes. Add a rate_limit block to the switch-chain 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 switch-chain completely? +

Set action: deny in the PolicyLayer policy for switch-chain. 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 switch-chain? +

switch-chain is provided by the MCPilot MCP server (xiawpohr/mcpilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
