AI agents call search_tasks to retrieve information from EspoCRM-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that searches and retrieves existing task data. It has no side effects, creates no new data, and performs no irreversible actions. The blast radius of misuse is minimal—an agent could only over-query or access tasks it shouldn't see, both of which are containable through proper access controls.
From the tool's definition Tool name 'search_tasks' and description 'Search for tasks using flexible criteria' indicate a query operation that retrieves task data without modifying, creating, or deleting anything.
Documented attack patterns abuse exactly the kind of access search_tasks gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and EspoCRM-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_tasks:
{
"version": "1",
"default": "deny",
"tools": {
"search_tasks": {}
}
}search_tasks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for tasks using flexible criteria. It is categorised as a Read tool in the EspoCRM-MCP MCP Server, which means it retrieves data without modifying state.
Register the EspoCRM- MCP server in PolicyLayer and add a rule for search_tasks: 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 EspoCRM-MCP. Nothing to install.
search_tasks 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_tasks 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_tasks. 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_tasks is provided by the EspoCRM- MCP server (zaphod-black/espomcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
