mcp_server

by GuillaumeMilan

Sec9

Provides an Elixir DSL for defining and serving Model Context Protocol (MCP) tools, prompts, and resources to AI agents, enabling them to interact with custom backend logic.

Setup Requirements

  • ⚠️Requires a working Elixir and Erlang/OTP environment to develop and run applications using this library.
  • ⚠️Relies on a Plug-compatible HTTP server like Bandit (`{:bandit, "~> 1.0"}`) for serving the MCP endpoints, which must be integrated into the application's supervision tree.
  • ⚠️Developers migrating from versions prior to v0.4.0 must adapt to significant breaking changes, including adding a 'conn' parameter to all controller functions, using struct notation (`.field`) instead of map notation (`["field"]`) for data access, and handling tuple returns from router list functions.
Verified SafeView Analysis
The library itself (McpServer) demonstrates a strong focus on type safety and input validation through its struct-based API and schema definitions, which inherently reduces common vulnerabilities. No 'eval', obfuscation, hardcoded secrets, or obvious malicious patterns were found in the provided source code snippets. The documentation explicitly advises respecting 'recommended security options for MCP servers' for the HTTP transport layer, indicating that deployment-level security (e.g., HTTPS, authentication, access control) is the responsibility of the application developer. Without access to the full `McpServer.HttpPlug` implementation or a complete application's configuration, a comprehensive security audit of a live deployment is not possible, but the library's design principles are sound.

Sec6

Orchestrates intelligent tool chaining, route optimization, and advanced thinking for complex development workflows and enterprise capabilities across an MCP ecosystem.

Setup Requirements

  • ⚠️Requires 'GITHUB_TOKEN' environment variable (a paid GitHub Personal Access Token) for 'awesome-copilot' integration, which is a key feature.
  • ⚠️Heavily relies on discovering and correctly configuring external MCP servers, including a specific hardcoded path for the 'awesome-copilot' dotnet executable (e.g., '/tmp/awesome-copilot-mcp/...'), making setup complex.
  • ⚠️Requires Node.js version 18.0.0 or higher.
Review RequiredView Analysis
The server's core functionality involves discovering and spawning external Model Context Protocol (MCP) servers (e.g., 'awesome-copilot', 'sequential-thinking') and executing their tools. This introduces an inherent security risk, as the server's security is dependent on the trustworthiness and security of all discovered and executed external processes. Sensitive information like 'GITHUB_TOKEN' is passed to these spawned processes via environment variables. The 'MEMORY_FILE_PATH' can be configured via an environment variable, which could pose a risk if an attacker can control this path to a sensitive location. While the server itself avoids direct dangerous patterns like 'eval' on untrusted input, its role as an orchestrator means it's a central point for potential vulnerabilities arising from the ecosystem it manages.

genesisdb-io icon
Sec3

Provides AI clients access to GenesisDB events, enabling natural language queries against the database.

Setup Requirements

  • ⚠️Requires an existing GenesisDB instance to connect to.
  • ⚠️Requires downloading a specific binary for your OS and architecture.
  • ⚠️The primary integration example is with Claude Desktop, requiring specific configuration within its settings.
  • ⚠️Requires a GenesisDB authentication token.
Review RequiredView Analysis
The server is distributed as a pre-compiled binary, and its source code is not provided for security auditing. As a 'Preview Release', it may contain unaddressed vulnerabilities. Running untrusted binaries carries inherent risks. The configuration requires providing a sensitive `GENESISDB_AUTH_TOKEN`.

Sec9

Provides a Model Context Protocol (MCP) API for AI agents to retrieve precise, locale-aware date and time data across timezones.

Setup Requirements

  • ⚠️Requires Node.js (version 18 or higher as indicated by `package.json` and `tsconfig.json`).
  • ⚠️Designed to run within a Model Context Protocol (MCP) environment and communicates via standard I/O (stdio), not as a standalone HTTP server by default.
Verified SafeView Analysis
The server uses `zod` for input validation for tool parameters and includes explicit timezone validation. There are no obvious `eval` statements, direct shell command executions from unvalidated user input, or hardcoded sensitive credentials within the provided source code. Communication over standard I/O (stdio) as an MCP service limits direct network attack surfaces, relying on the security of the encompassing MCP runtime.

mcp-autotask-search

by JM-Addington

Sec9

Exposes Autotask search functionality for tickets, companies, and contacts to LLMs like Claude via the Model Context Protocol.

Setup Requirements

  • ⚠️Requires a separate Autotask Django API server to be running and accessible (default: http://localhost:8000).
  • ⚠️Requires Python 3.10 or higher.
  • ⚠️A valid `AUTOTASK_API_KEY` is mandatory for authentication with the Autotask API.
  • ⚠️When configuring for Claude Desktop/Cursor, the `command` path to `run.sh` must be absolute.
Verified SafeView Analysis
The server uses `httpx` for API calls and retrieves the `AUTOTASK_API_KEY` from environment variables, which is good practice. The `BASE_URL` defaults to `http://localhost:8000`, limiting direct external exposure unless explicitly configured. There are no `eval` calls or clear obfuscation. Potential risks include the security of the underlying Autotask Django API server and ensuring the `AUTOTASK_API_KEY` itself is securely managed and has appropriate permissions.

claude-memory-mcp

by Stig-Johnny

Sec8

Provides persistent memory capabilities for Claude Code agents, allowing them to store and recall decisions, error solutions, project context, learnings, and session state across conversations, with optional cloud synchronization.

Setup Requirements

  • ⚠️Requires manual installation steps including cloning the repository, installing Node.js dependencies (with an optional Firestore package), copying slash command files, and manually configuring ~/.claude/settings.json.
  • ⚠️Optional Google Cloud Firestore sync setup is multi-step, requiring creating a Firebase project, setting up a Firestore database, generating a service account key, and configuring a local memory-config.json file.
  • ⚠️The `@google-cloud/firestore` package must be installed separately if cloud sync is desired.
Verified SafeView Analysis
The server uses SQLite locally and prepared statements, mitigating common SQL injection risks. Optional cloud sync with Google Cloud Firestore requires users to generate and secure a service account key (`firestore-key.json`), which should never be committed to Git. Users are explicitly warned against storing secrets (e.g., API keys, passwords) directly in memory, recommending environment variables instead. Firestore security rules are the user's responsibility for production use. Overall, the code itself is not inherently insecure, but relies on proper user configuration and handling of external secrets and cloud service security.

Sec6

Provides a backend API for managing school-related data, likely serving information stored in a SQLite database.

Setup Requirements

  • ⚠️Requires Python dependencies to be installed from requirements.txt (e.g., pip install -r requirements.txt).
  • ⚠️The 'school.db' SQLite database file must be present in the expected location and potentially contain a specific schema or initial data for the server to function correctly.
Review RequiredView Analysis
Cannot fully audit without code content. The presence of 'school.db' suggests potential storage of sensitive data. Exposing this server without proper authentication, authorization, and input validation could pose significant security risks. As a 'sample', default security might be minimal.

KWR-Water icon

epanet-mcp-server

by KWR-Water

Sec3

Provides tools for fetching real-time weather information from the NWS API and running EPANET water network simulations.

Setup Requirements

  • ⚠️The `epyt` library, used for EPANET simulations, is a required dependency but is not listed in `pyproject.toml`'s main `dependencies` array and needs to be installed separately.
  • ⚠️The `get_inp_files` tool uses a hardcoded absolute path (`C:/Users/.../models`) for the models directory. This path must be manually changed or exactly match the environment for the server to function correctly.
  • ⚠️The server requires Python 3.11 or newer.
Review RequiredView Analysis
The server has a critical path traversal vulnerability in the `run_epanet_simulation` tool. A manipulated `file_name` argument (e.g., `../secrets.txt`) could allow the server to access and potentially process arbitrary files outside the intended `models` directory. Additionally, the `get_inp_files` tool uses a hardcoded absolute path (`C:/Users/.../models`) which is a security risk (exposing internal system structure) and severely impacts portability. No hardcoded secrets were found in the API keys or critical credentials, but the file system access issues are significant.

fourtrader-mcp

by menscheck

Sec3

Serves as a trading engine for Four.meme tokens on BNB Smart Chain, providing AI-driven insights and executing trades.

Setup Requirements

  • ⚠️Requires Wallet Private Key for trading functions, which must be provided in the .env file.
  • ⚠️Requires a Bitquery API Key for comprehensive market data; many data-fetching tools will return limited information without it.
  • ⚠️Designed for integration with Claude Desktop, requiring manual modification of 'claude_desktop_config.json' with the full path to the project.
Review RequiredView Analysis
The trading functions ('buy_token' and 'sell_token') have a critical security vulnerability: 'minTokensOut' and 'minBnbOut' are hardcoded to 0. This means transactions are executed without any slippage protection, exposing user funds to potential 100% loss due to price fluctuations or malicious actors. Additionally, 'poolAddress' in 'buy_token' is hardcoded, which might not be universally correct or robust. While private keys and API keys are correctly managed via environment variables and security documentation is present, the fundamental lack of slippage control makes the trading aspect highly unsafe.

nexus-mcp-server

by fabriziosalmi

Sec7

The Nexus MCP Server provides a micro-capability platform (MCP) exposing a wide array of developer tools via a REST API, enabling tasks from mathematical operations and cryptographic functions to system management, network diagnostics, cloud resource optimization, and dynamic code execution across multiple programming languages.

Setup Requirements

  • ⚠️Requires several Python libraries (e.g., `psutil`, `cryptography`, `httpx`, `dnspython`, `PyPDF2`, `pdfplumber`) to be installed.
  • ⚠️Relies on external system binaries (`git`, `ping`, `traceroute`, `whois`, `systemctl`, `nmap`, `curl`, `wget`, `node`) which must be available on the host or in the Docker image.
  • ⚠️Optimal and secure execution of dynamic code (Python/JavaScript) is designed to run within a Dockerized sandbox environment, necessitating Docker daemon availability.
Review RequiredView Analysis
The server includes extensive capabilities for dynamic code execution (Python, JavaScript) and shell command execution, as well as system/process management and network scanning. Developers have implemented significant security measures including input validation, whitelisting/blacklisting for dangerous operations/imports, resource limits for code execution, and filesystem sandboxing for file operations. However, executing arbitrary user-provided code/commands, even with safeguards, inherently carries risks of bypasses or resource exhaustion. Reliance on external system binaries also introduces a dependency on their security. Running this server in a tightly controlled Docker environment with minimal privileges, as suggested by the `docker-compose.yml`, is crucial to mitigate these inherent risks.

Sec9

Enables AI assistants to interact with and manage projects, tasks, goals, milestones, and notes within the Joan productivity app.

Setup Requirements

  • ⚠️Requires interactive browser login for authentication (OAuth flow).
  • ⚠️Requires Node.js version 18 or higher.
  • ⚠️Claude Code restart is necessary after initial setup for changes to take effect.
Verified SafeView Analysis
The server uses strong cryptographic methods (AES-256-GCM, scryptSync) for local authentication token storage and restricts file permissions (0o600). OAuth is used for authentication via a local HTTP callback server, which is well-controlled and times out. Usage of `child_process.spawn` for opening the browser and configuring Claude CLI is for hardcoded commands or locally-derived URLs, reducing the risk of arbitrary command injection. JWT parsing is used only for expiration checks and email extraction, not for authentication verification, which relies on the backend API call. No direct `eval` or blatant obfuscation detected.

Sec8

A server that interacts with GitHub's API to automate tasks like updating comments, managing pull requests, and manipulating files.

Setup Requirements

  • ⚠️Requires a GitHub Personal Access Token with appropriate permissions.
  • ⚠️Requires Go 1.21 or higher for building from source, or Docker for running via image.
Verified SafeView Analysis
The code relies on a GITHUB_TOKEN for authentication, which should be handled securely. It doesn't appear to use dangerous functions like 'eval'. Network risks are primarily related to the GitHub API itself. No hardcoded secrets found. The use of go-github library is standard for interacting with the GitHub API.
