WHAT IT DOES

What mcp_reload does on 1MCP Server

AI agents invoke mcp_reload to trigger actions in 1MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why mcp_reload is rated High

Reloading an MCP server or configuration is an operational trigger that restarts or reinitializes a live service. This is an Execute-category action because it causes an external system operation whose effects depend on the current state and configuration. It could disrupt active connections, apply new (potentially malicious) configurations, or alter the behavior of all aggregated MCP servers.

From the tool's definition "Reload MCP server or configuration" — triggers a reload/restart operation on a running MCP server or its configuration

RECOMMENDED RULE

The rule that runs mcp_reload safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 1MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mcp_reload, this is the rule to start with:

mcp_reload Rate-limited

mcp_reload stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect 1MCP Server, apply this rule, and every mcp_reload call is checked against it from then on.

How do I enforce a policy on mcp_reload? +

Register the 1MCP Server MCP server in PolicyLayer and add a rule for mcp_reload: 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 1MCP Server. Nothing to install.

What risk level is mcp_reload? +

mcp_reload is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit mcp_reload? +

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

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