AI agents call search_teams 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.
The tool performs a search operation to retrieve team information. Search operations are read-only and do not modify, delete, or execute anything. The blast radius of misuse is minimal—an AI agent could only retrieve team data that may already be accessible through normal system permissions. No financial, destructive, or code execution risk is present.
From the tool's definition Tool name is 'search_teams' and description states 'Search for teams in the system' — this is a query/search operation that retrieves data with no side effects.
Documented attack patterns abuse exactly the kind of access search_teams 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_teams:
{
"version": "1",
"default": "deny",
"tools": {
"search_teams": {}
}
}search_teams is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for teams in the system. 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_teams: 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_teams 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_teams 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_teams. 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_teams 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.
