AI agents call show_project to retrieve information from Redmine MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries project data from Redmine without creating, modifying, or deleting any resources. It is a straightforward read operation that has no blast radius if misused by an AI agent, as it cannot cause data loss, financial impact, or unintended modifications.
From the tool's definition Tool name 'show_project' and description 'Get detailed project information' indicate a retrieval operation with no modifications or side effects.
Documented attack patterns abuse exactly the kind of access show_project gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Redmine MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for show_project:
{
"version": "1",
"default": "deny",
"tools": {
"show_project": {}
}
}show_project is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed project information. It is categorised as a Read tool in the Redmine MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Redmine MCP Server MCP server in PolicyLayer and add a rule for show_project: 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 Redmine MCP Server. Nothing to install.
show_project is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the show_project 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 show_project. 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.
show_project is provided by the Redmine MCP Server MCP server (yonaka15/mcp-server-redmine). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
