CockroachDB MCP Server — agentic threat model
This MCP server exposes direct SQL execution and schema inspection on CockroachDB clusters, introducing high-severity risks of arbitrary database manipulation, data exfiltration, and credential exposure if the calling agent is compromised or manipulated.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — The MCP server itself does not bundle a specific foundation model, but any connected LLM is susceptible to prompt injection that could craft malicious SQL queries to bypass intended application logic.
Directly exposes CockroachDB cluster data. Key threats include unauthorized data exfiltration, schema modification, and data poisoning via arbitrary SQL execution tools provided to the agent.
The framework exposes powerful database tools (SQL query execution, schema inspection). Insecure tool integration or lack of input sanitization allows downstream LLMs to execute destructive DDL/DML commands.
Requires a connection string containing sensitive database credentials. If the MCP server hosting environment is compromised, these credentials can be leaked, granting full database access.
Not certain from the listing — There is no mention of built-in query logging, SQL audit trails, or guardrails to intercept destructive commands before they reach the CockroachDB cluster.
Relies entirely on connection-string authentication. Lacks granular, user-level authorization or row-level security controls within the MCP layer itself, inheriting all permissions of the configured database user.
In a multi-agent or marketplace setup, any agent granted access to this MCP server inherits full read/write capabilities over the database, risking cascading data compromise if a connected agent is malicious.
