Retrieve the most relevant text or image pages for a given query. Always call this before answering knowledge-based questions.
AI agents call retrieve-chunks 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.
This tool performs a semantic search query against the Morphik database to fetch relevant document chunks or pages. It is purely read-only—it queries existing data without creating, modifying, deleting, or executing arbitrary operations. The instruction to 'call this before answering knowledge-based questions' confirms its role as a retrieval mechanism. No side effects or destructive actions are possible.
From the tool's definition Tool name 'retrieve-chunks' and description 'Retrieve the most relevant text or image pages for a given query' indicate a retrieval operation with no modification or deletion of data.
Documented attack patterns abuse exactly the kind of access retrieve-chunks 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 retrieve-chunks:
{
"version": "1",
"default": "deny",
"tools": {
"retrieve-chunks": {}
}
}retrieve-chunks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve the most relevant text or image pages for a given query. Always call this before answering knowledge-based questions. 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 retrieve-chunks: 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.
retrieve-chunks 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 retrieve-chunks 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 retrieve-chunks. 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.
retrieve-chunks 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.
