Search for documents by filename or title using full-text search. Use this to discover documents before retrieving their content.
AI agents call search-documents to retrieve information from Morphik MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only search to discover documents before content retrieval. It retrieves information (search results) without creating, modifying, deleting, or executing operations. The blast radius of misuse is limited to information disclosure, making this a Read category risk at low severity.
From the tool's definition Tool description states 'Search for documents by filename or title using full-text search.' This is a query operation with no modification or deletion of data.
Documented attack patterns abuse exactly the kind of access search-documents gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Morphik MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search-documents:
{
"version": "1",
"default": "deny",
"tools": {
"search-documents": {}
}
}search-documents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for documents by filename or title using full-text search. Use this to discover documents before retrieving their content. It is categorised as a Read tool in the Morphik MCP MCP Server, which means it retrieves data without modifying state.
Register the Morphik MCP server in PolicyLayer and add a rule for search-documents: 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 Morphik MCP. Nothing to install.
search-documents 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-documents 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-documents. 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-documents is provided by the Morphik MCP server (morphik-org/morphik-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Morphik MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
