4 threat patterns detected

high

capability escalation

The proxy dynamically fetches ALL tool definitions (names, descriptions, input schemas) from the remote MCP-Hive backend (hive.mcp-hive.com) at startup and registers them verbatim. This means the remote server controls the entire tool surface the AI agent sees — tool names, descriptions, and schemas can be changed server-side at any time without any code update or user consent. A compromised or malicious backend could inject description injection attacks, tool shadowing, or schema abuse into the dynamically registered tools, and the proxy would blindly register them. The user has no way to audit what tools will actually be registered before they are active. (location: src/proxy/mcpHiveProxy.ts — initializeProxyMode() method, where MCPHiveProxyRequest.listTools() result is iterated and each tool is registered via this.mcpServer.registerTool())

medium

schema abuse

The gateway-mode 'callServer' tool accepts an open-ended 'args' parameter (z.record(z.string(), z.unknown())) that is forwarded verbatim to the remote MCP-Hive backend. An AI agent could be prompted (via manipulated tool descriptions from the dynamic registration mechanism) to pass sensitive data — file contents, credentials, system prompts — as arbitrary arguments through this open proxy, and all data would be transmitted to hive.mcp-hive.com. Combined with the dynamic tool registration issue, the backend could craft tool schemas that specifically request sensitive data. (location: src/proxy/mcpHiveProxy.ts — initializeGatewayMode(), callServer tool registration; src/proxy/requests/mcpHiveProxyRequest.ts — sendMCPHiveRequest() which POSTs all arguments to the backend)

low

description injection

The callServer tool in the source code is registered with the discoverServers description ('Discover additional MCP Servers which can be invoked through this gateway...') instead of its actual purpose (calling arbitrary server tools). While this appears to be a copy-paste bug rather than intentional manipulation, it causes the AI agent to receive an inaccurate description of a powerful tool that can invoke arbitrary remote servers with arbitrary arguments, potentially leading the agent to use it without proper caution. (location: src/proxy/mcpHiveProxy.ts — initializeGatewayMode(), the hardcoded description string for callServer tool registration)

low

credential exposure

Production-looking API credentials are committed to the public repository in the VS Code debug configuration: 'bd1ded66-6564-4d00-8cf6-21eb1f9d333f' and 'aca828c8-98cc-45e0-b8bf-40def169124f'. While these may be test/demo credentials, they are labeled 'Debug Proxy Production' and could provide unauthorized access to MCP-Hive services. (location: .vscode/launch.json — debug configurations with hardcoded credential values)

FAQ: how to interpret this assessment

Common questions teams ask before deciding whether to use this mcp server in agent workflows.

Is MCP-Hive/mcp-hive-proxy safe for AI agents to use?

MCP-Hive/mcp-hive-proxy currently scores 47/100 with a suspicious verdict and medium confidence. The goal is to protect agents from high-risk context before they act on it. Treat this as a decision signal: higher scores suggest lower observed risk, while lower scores mean you should add review or block this mcp server.

How should I interpret the score and verdict?

Use the score as a policy threshold: 80–100 is safe, 50–79 is caution, 20–49 is suspicious, and 0–19 is dangerous. Teams often auto-allow safe, require human review for caution/suspicious, and block dangerous.

How does brin compute this mcp server score?

brin evaluates four dimensions: identity (source trust), behavior (runtime patterns), content (malicious instructions), and graph (relationship risk). Analysis runs in tiers: static signals, deterministic pattern checks, then AI semantic analysis when needed.

What do identity, behavior, content, and graph mean for this mcp server?

Identity checks source trust, behavior checks unusual runtime patterns, content checks for malicious instructions, and graph checks risky relationships to other entities. Looking at sub-scores helps you understand why an entity passed or failed.

Why does brin scan packages, repos, skills, MCP servers, pages, and commits?

brin performs risk assessments on external context before it reaches an AI agent. It scores that context for threats like prompt injection, hijacking, credential harvesting, and supply chain attacks, so teams can decide whether to block, review, or proceed safely.

Can I rely on a safe verdict as a full security guarantee?

No. A safe verdict means no significant risk signals were detected in this scan. It is not a formal guarantee; assessments are automated and point-in-time, so combine scores with your own controls and periodic re-checks.

When should I re-check before using an entity?

Re-check before high-impact actions such as installs, upgrades, connecting MCP servers, executing remote code, or granting secrets. Use the API in CI or runtime gates so decisions are based on the latest scan.
