ynab-mcpb

by dizzlkheinz

Sec9

Connects a YNAB budget to an MCP client (e.g., Claude Desktop) to manage finances using natural language, including receipt itemization and bank reconciliation.

Setup Requirements

  • ⚠️Requires a YNAB Personal Access Token (YNAB_ACCESS_TOKEN) for full functionality.
  • ⚠️Requires a Node.js environment to run (via npx).
  • ⚠️Requires an MCP-compatible client (e.g., Claude Desktop, VS Code's Cline, Codex) to interact with as an AI tool.
Verified SafeView Analysis
The server follows good security practices by requiring a YNAB access token via environment variables and not hardcoding secrets. It implements input validation using Zod schemas, rate limiting, and request logging with sensitive parameter sanitization. File system access for CSV import and JSON export is appropriately constrained to prevent path traversal. Tool annotations provide security hints (e.g., 'readOnlyHint', 'destructiveHint') to the LLM. No 'eval' or similar dangerous patterns were identified in the provided code snippets.

Sec9

Transforms Claude into an ultra-efficient, production-grade AI pair programmer by orchestrating best-in-class code APIs for iterative code evolution, semantic search within local repositories and public packages, and pattern learning.

Setup Requirements

  • ⚠️Requires Morph API Key (paid service)
  • ⚠️Requires Chroma Package Search API Key (paid tier available)
  • ⚠️Requires OpenRouter API Key (paid service, for GEPA/DSPy LLM backend)
  • ⚠️Requires Python 3.13+ and Git
Verified SafeView Analysis
The server leverages environment variables (os.getenv) for all API keys (Morph, Chroma, OpenRouter), which is a secure practice. Its core `evolve_code` functionality aims to improve code quality, explicitly checking for and reducing security vulnerabilities like SQL injection, `eval`/`exec`, and insecure password handling within the code it generates or modifies. The reliance on external LLMs (GEPA/OpenRouter and Morph) for code generation means that the security of the *output code* is dependent on the LLM's capabilities and training, although the server's own analysis and iterative refinement process are designed to mitigate these risks. No direct malicious patterns or obfuscation were found in the server's own codebase.

web3-tools-mcp

by hajnalben

Sec8

Facilitates multi-chain blockchain interactions, smart contract analysis, transaction signing, and real-time data retrieval for AI agents and developers.

Setup Requirements

  • ⚠️Requires Node.js >= 20.0.0.
  • ⚠️Full functionality (e.g., contract ABI/source retrieval, fast event queries, enhanced RPC) requires optional API keys (Etherscan, Hypersync, Alchemy, Infura).
  • ⚠️Transaction signing (write operations) requires a browser wallet (MetaMask, Rabby, Coinbase Wallet) and the server will automatically open a browser window for approval on a local port (e.g., http://localhost:3456).
Verified SafeView Analysis
The server includes a local web server (http://localhost:3456) and WebSocket server for browser wallet integration, which automatically opens a browser window for transaction approval. This design keeps private keys off the server but relies on local system security and user vigilance for transaction signing in the browser. API keys are loaded from environment variables or CLI, preventing hardcoding. No 'eval' or obfuscation found.

A comprehensive Model Context Protocol (MCP) server for mobile device automation. It controls Android and iOS devices programmatically through a standardized interface, ideal for testing, automation, and AI-assisted mobile app development.

Setup Requirements

  • ⚠️Requires Rust 1.70+ toolchain installed.
  • ⚠️iOS support (simulators/physical devices) is exclusively available on macOS.
  • ⚠️iOS Simulators require Xcode Command Line Tools (`xcode-select --install`).
  • ⚠️iOS Physical Devices require `libimobiledevice` (`brew install libimobiledevice`) for extended functionality on macOS.
Verified SafeView Analysis
The server uses `adb_client` and `xcrun simctl` for device control, which inherently involves executing shell commands. While arguments are generally passed as separate strings to `Command::new`, minimizing direct shell injection, the `send_keys` function in `src/devices/android.rs` performs manual string escaping for `input text` commands. Manual escaping is error-prone and could potentially lead to vulnerabilities if not perfectly robust against all possible inputs. The use of an unspecified `com.mobilenext.devicekit` for non-ASCII text on Android also introduces an un-audited component. No hardcoded secrets or obvious malicious patterns were found. The server primarily communicates via stdin/stdout and local ADB/USB connections.

poly-git-mcp

by Grifex-0

Sec6

A unified Model Context Protocol (MCP) server that enables AI assistants and other MCP clients to manage Git repositories, issues, pull requests, and CI/CD across GitHub, GitLab, Gitea, and Bitbucket.

Setup Requirements

  • ⚠️Requires Deno runtime (v2.0+) to be installed.
  • ⚠️Requires respective Git CLI tools (gh, glab, tea) to be installed and configured in the execution environment for GitHub, GitLab, and Gitea functionality.
  • ⚠️Bitbucket functionality requires `BITBUCKET_USERNAME` and `BITBUCKET_APP_PASSWORD` environment variables to be set for authentication.
Verified SafeView Analysis
The server requires extensive Deno permissions (`--allow-run`, `--allow-net`, `--allow-read`, `--allow-env`, `--allow-write`) to execute external CLI tools (`gh`, `glab`, `tea`) and make direct API calls (Bitbucket). While these permissions are necessary for its functionality and clearly documented, they expose the system to significant risk if the server is compromised or given overly broad credentials. User credentials (GitHub/GitLab/Gitea tokens, Bitbucket username/app password) are directly used, making the security boundary dependent on the scope of these credentials. The code does not use `eval` or show obvious command injection vulnerabilities in its argument parsing for CLI calls (arguments are passed as distinct strings to Deno.Command). Users must carefully manage the scope of authentication tokens.

WhatsApp-AI-Bot

by YOUHAD08

Sec8

An intelligent WhatsApp chatbot that leverages a dedicated MCP server for dynamic tool management, enabling employee data queries via Spring AI and OpenAI's GPT-4.

Setup Requirements

  • ⚠️Requires an OpenAI API Key (paid service)
  • ⚠️Requires a Meta Business Account and WhatsApp Business API access (complex setup)
  • ⚠️Requires ngrok for exposing local server to Meta's webhooks during development
Verified SafeView Analysis
The application employs environment variables for sensitive data like API keys and verification tokens, which is a good practice. User input (message text) is escaped before being included in JSON payloads, mitigating potential JSON injection risks when communicating with the Meta WhatsApp API. Webhook verification ensures authenticity of incoming requests. The architecture's separation into a main bot service and a distinct MCP server for tools enhances modularity and potentially reduces the attack surface. No direct 'eval' or easily exploitable code injection vulnerabilities are apparent in the provided source code. Primary security considerations would revolve around prompt injection for the LLM and the secure management of API keys and server exposure during deployment.

whoosh_rag_mcp

by jianlins

Sec8

Provides full-text search for documentation to AI assistants using Whoosh, enabling RAG over up-to-date information.

Setup Requirements

  • ⚠️Requires Python 3.8+.
  • ⚠️Requires `DOCS_ROOT` and `INDEX_DIR` environment variables to be configured for documentation and index paths.
  • ⚠️Requires an initial index build via the `build_documentation_index` tool or CLI command before search functionality is available.
Verified SafeView Analysis
The core Python MCP server (mcp_server.py, doc_retriever.py) does not contain direct `eval`, hardcoded secrets, or network listeners (uses stdio). File operations are limited to configured `DOCS_ROOT` and `INDEX_DIR`. The primary risk lies in the configuration of `DOCS_ROOT` and `INDEX_DIR` environment variables by the host system or AI assistant client; if these point to untrusted or sensitive locations, it could lead to unintended file access or resource exhaustion. The associated VS Code extension uses `child_process.exec` to run the Python script, which is a potential vulnerability if the `pythonPath` configuration is maliciously set by the user, though the script path itself is fixed and arguments for search queries are quoted to mitigate injection.

sharepoint-mcp

by peacockery-studio

Sec8

Provides Claude with access to Microsoft SharePoint for folder and document management via the Microsoft Graph API.

Setup Requirements

  • ⚠️Requires manual Azure AD Application registration, including setting redirect URI, creating a client secret, and configuring API permissions (Sites.ReadWrite.All, Files.ReadWrite.All).
  • ⚠️Granting admin consent for Azure AD API permissions may be required, which necessitates Azure AD admin privileges.
  • ⚠️Initial authentication requires running a separate local HTTP server (`npm run auth-server`) and completing a browser-based OAuth flow.
Verified SafeView Analysis
The server correctly uses environment variables for sensitive credentials (client ID, client secret, tenant ID). OAuth tokens are stored locally in a file (`~/.sharepoint-mcp-tokens.json`), which is a common practice for local MCP servers, but implies that these tokens are vulnerable if the user's local machine is compromised. The authentication server runs on localhost using HTTP, which is standard for local OAuth callback flows. No 'eval' or obvious malicious patterns were found.

Sec3

Manages employee data (CRUD) via Model Context Protocol (MCP) using various transports (HTTP SSE, Stdio, WebSocket) with Google OAuth for authentication and an external JSON-server for data storage.

Setup Requirements

  • ⚠️The `ENCRYPTION_KEY` environment variable is critical for secure token storage; if not set, an insecure default key is used, making user tokens vulnerable.
  • ⚠️Requires a separate external JSON-server API to be running concurrently on port 4000 via `node Deployment/run_api.js` for data persistence.
  • ⚠️The Stdio mode starts a local Express server on port 3000 (or `PORT` in .env) for OAuth callbacks, which can lead to port conflicts if another service (like the HTTP server) is already running on the same port.
Review RequiredView Analysis
CRITICAL: The `ENCRYPTION_KEY` used for token storage defaults to an 'insecure-default-secret' if the `ENCRYPTION_KEY` environment variable is not explicitly set. This makes stored authentication tokens vulnerable if deployed without proper configuration. Additionally, CORS is broadly enabled without specific origin restrictions, which might be a security concern in production environments. The external API endpoint relies on `http://localhost:4000` by default, which should be secured if exposed externally.
