Search for content within files. Supports plain text and regex search. Returns matching lines with file path and line number. Only searches within allowed directories.
AI agents call search_content to retrieve information from Claude TypeScript MCP Servers 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 data (file contents) without creating, modifying, deleting, or executing anything. It has minimal blast radius—the worst outcome of misuse would be information disclosure of already-accessible file content. No side effects, no data mutation, no code execution.
From the tool's definition Tool description states it "Search[es] for content within files" and "Returns matching lines with file path and line number." These are retrieval operations with no modification or execution capability.
Documented attack patterns abuse exactly the kind of access search_content gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude TypeScript MCP Servers, and nothing reaches the server without passing your rules. This is the rule we recommend for search_content:
{
"version": "1",
"default": "deny",
"tools": {
"search_content": {}
}
}search_content is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Search for content within files. Supports plain text and regex search. Returns matching lines with file path and line number. Only searches within allowed directories. It is categorised as a Read tool in the Claude TypeScript MCP Servers MCP Server, which means it retrieves data without modifying state.
Register the Claude TypeScript MCP Servers MCP server in PolicyLayer and add a rule for search_content: 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 Claude TypeScript MCP Servers. Nothing to install.
search_content 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 search_content 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 search_content. 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.
search_content is provided by the Claude TypeScript MCP Servers MCP server (ukkz/claude-ts-mcps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Claude TypeScript MCP Servers, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
