get_connection_string
Return database connection details
Part of the Neon MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call get_connection_string to retrieve information from Neon without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.
WHY ENFORCE A POLICY ON GET_CONNECTION_STRING
Even though get_connection_string only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
RECOMMENDED POLICY
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

FREQUENTLY ASKED QUESTIONS
What does the get_connection_string tool do?
Return database connection details. It is categorised as a Read tool in the Neon MCP Server, which means it retrieves data without modifying state.
How do I enforce a policy on get_connection_string?
Add a rule in your Intercept YAML policy under the tools section for get_connection_string. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Neon MCP server.
What risk level is get_connection_string?
get_connection_string is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Can I rate-limit get_connection_string?
Yes. Add a rate_limit block to the get_connection_string rule in your Intercept 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.
How do I block get_connection_string completely?
Set action: deny in the Intercept policy for get_connection_string. 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.
What MCP server provides get_connection_string?
get_connection_string is provided by the Neon MCP server (neondatabase/mcp-server-neon). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
