Atomically replace STRATEGY.md with the provided markdown.
AI agents use mureo_strategy_set to create or update resources in Mureo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mureo environment.
This tool modifies a foundational configuration file (STRATEGY.md) that governs the AI agent's behavior and decision-making. While not irreversible in a technical sense (the file can be restored from version control or backups), the atomic replacement of a strategy document that 'grounds' the system's behavior represents a high-severity Write operation.
From the tool's definition Tool description states 'Atomically replace STRATEGY.md with the provided markdown' — a direct modification operation on a critical configuration file.
Documented attack patterns abuse exactly the kind of access mureo_strategy_set gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mureo, and nothing reaches the server without passing your rules. This is the rule we recommend for mureo_strategy_set:
{
"version": "1",
"default": "deny",
"tools": {
"mureo_strategy_set": {
"limits": [
{
"counter": "mureo_strategy_set_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}mureo_strategy_set 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.

Atomically replace STRATEGY.md with the provided markdown. It is categorised as a Write tool in the Mureo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mureo MCP server in PolicyLayer and add a rule for mureo_strategy_set: 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 Mureo. Nothing to install.
mureo_strategy_set 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 mureo_strategy_set 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 mureo_strategy_set. 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.
mureo_strategy_set is provided by the Mureo MCP server (logly/mureo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mureo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
