Search templates by keyword (name, description, type, tags, or code content).
AI agents call searchTemplates to retrieve information from Mcp Mermiad without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves or queries existing template data based on search keywords. It performs a read-only search across template metadata (name, description, type, tags, code content) and returns matching results. There are no side effects, no data modification, no code execution, and no destructive capabilities.
From the tool's definition Tool description explicitly states "Search templates by keyword" - this is a search/query operation with no capability to modify, delete, or execute code. Returns matching templates based on search criteria.
Documented attack patterns abuse exactly the kind of access searchTemplates gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Mermiad, and nothing reaches the server without passing your rules. This is the rule we recommend for searchTemplates:
{
"version": "1",
"default": "deny",
"tools": {
"searchTemplates": {}
}
}searchTemplates is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search templates by keyword (name, description, type, tags, or code content). It is categorised as a Read tool in the Mcp Mermiad MCP Server, which means it retrieves data without modifying state.
Register the Mcp Mermiad MCP server in PolicyLayer and add a rule for searchTemplates: 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 Mcp Mermiad. Nothing to install.
searchTemplates 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 searchTemplates 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 searchTemplates. 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.
searchTemplates is provided by the Mcp Mermiad MCP server (narasimhaponnada/mermaid-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Mermiad, 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.
