run_sql_plus_plus_query

Run a SQL++ query on a Couchbase scope

Executes arbitrary SQL++ on database

Part of the Couchbase MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke run_sql_plus_plus_query to trigger processes or run actions in Couchbase. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

// WHY ENFORCE A POLICY ON RUN_SQL_PLUS_PLUS_QUERY

run_sql_plus_plus_query can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

  run_sql_plus_plus_query:

What does the run_sql_plus_plus_query tool do? +

Run a SQL++ query on a Couchbase scope. It is categorised as a Execute tool in the Couchbase MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run_sql_plus_plus_query? +

Add a rule in your Intercept YAML policy under the tools section for run_sql_plus_plus_query. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Couchbase MCP server.

What risk level is run_sql_plus_plus_query? +

run_sql_plus_plus_query is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit run_sql_plus_plus_query? +

Yes. Add a rate_limit block to the run_sql_plus_plus_query 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 run_sql_plus_plus_query completely? +

Set action: deny in the Intercept policy for run_sql_plus_plus_query. 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 run_sql_plus_plus_query? +

run_sql_plus_plus_query is provided by the Couchbase MCP server (@couchbase-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
