Get the default field mapping for a connection. Mappings define how event payload fields map to destination fields with optional transforms (trim, lower, upper, to_string, etc.).
AI agents call meshes_get_connection_default_mappings to retrieve information from Mesheshq 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 existing mapping configuration for a connection. It performs no side effects, does not modify data, and does not trigger external operations. The action is purely informational, making it a Read operation with low severity since misuse would only expose field mapping metadata rather than enable destructive or financial actions.
From the tool's definition Tool name contains 'get_' prefix and description states 'Get the default field mapping for a connection', indicating retrieval of existing configuration data without modification.
Attacks that exploit this kind of access
Get the default field mapping for a connection. Mappings define how event payload fields map to destination fields with optional transforms (trim, lower, upper, to_string, etc.). It is categorised as a Read tool in the Mesheshq MCP Server, which means it retrieves data without modifying state.
Register the Mesheshq MCP server in PolicyLayer and add a rule for meshes_get_connection_default_mappings: 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 Mesheshq. Nothing to install.
meshes_get_connection_default_mappings 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 meshes_get_connection_default_mappings 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 meshes_get_connection_default_mappings. 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.
meshes_get_connection_default_mappings is provided by the Mesheshq MCP server (mesheshq/meshes-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
