List all available CosmosDB connections configured in this MCP server. Use this to discover which connection_id values you can use. Each connection points to a different CosmosDB account/database.
AI agents call mcp_list_connections to retrieve information from Mcpcosmosdb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves connection configuration information without creating, modifying, deleting, or executing any operations. It is a passive discovery mechanism for listing available connections. The blast radius is minimal—an agent learning what connections exist poses no direct risk of data loss, financial impact, or unauthorized modifications.
From the tool's definition Tool description explicitly states 'List all available CosmosDB connections' — a retrieval operation with no modification or side effects.

List all available CosmosDB connections configured in this MCP server. Use this to discover which connection_id values you can use. Each connection points to a different CosmosDB account/database. It is categorised as a Read tool in the Mcpcosmosdb MCP Server, which means it retrieves data without modifying state.
Register the Mcpcosmosdb MCP server in PolicyLayer and add a rule for mcp_list_connections: 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 Mcpcosmosdb. Nothing to install.
mcp_list_connections 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 mcp_list_connections 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 mcp_list_connections. 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.
mcp_list_connections is provided by the Mcpcosmosdb MCP server (mcpcosmosdb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
