Free MCP Server Lets Claude and Cursor Convert Files Without an API Key

·3 views

Language models can discuss files but cannot open them directly, so users often end up with invented commands or long lists of local tools to install. The article describes a free, remote MCP server from CleverUtils at a public URL that requires no API key or signup, letting editors like Cursor and Claude Desktop call real file-conversion tools. The server offers fifteen tools covering format conversion, image upscaling and background removal, PDF compression and merging, and speech-to-text transcription. Usage is rate-limited per IP address, with daily and hourly caps, file size limits of up to 200 MB, and output download links that expire after two hours. Setup involves adding the server URL to the client's MCP settings, with an npx-based bridge needed for Claude Desktop, and connectivity can be verified with a simple curl request.

How to block a program from accessing the internet on Windows

Windows users can stop a program from connecting online by creating an outbound rule in Windows Defender Firewall. The process involves locating the program's .exe file and then creating a block rule through the Advanced Security console or a PowerShell command. Users should note that the standard Allow an app setting in Control Panel only governs incoming connections and will not stop outgoing traffic. Some programs rely on several executables, such as updaters or helpers, so each one may need its own rule. The rule takes effect immediately and can be disabled or deleted at any time.

How to Connect Cursor, Continue, and Open WebUI to the N3mak OpenAI-Compatible Gateway

The guide explains how tools that speak the OpenAI Chat Completions format can be pointed at any compatible base URL. It covers configuring three popular clients, Cursor, Continue, and Open WebUI, to use the N3mak AI Gateway with a base URL, a Bearer API key, and a model identifier. The gateway's supported endpoints are listed, including model listing and chat completions, with gpt-oss-20b as the default model. Model availability varies by plan, from the free trial up to the Pro tier, and the guide notes which Cursor features the custom endpoint does not cover. Step-by-step setup instructions and curl test examples are provided for each client, using placeholder keys rather than live credentials.

Anthropic Outlines Its Multi-Stage Hiring Process for Engineering Candidates

Anthropic evaluates software engineering and research candidates on more than coding skill, including fundamentals, judgment, communication, and alignment with its mission. A typical process begins with a recruiter screen, followed by a technical assessment, a hiring manager interview, a virtual onsite loop, and a culture and project review. The exact sequence differs by role, seniority, and team, and the company does not publish a single standardized schedule. The guide notes that stages such as the technical screen may use tools like CodeSignal or Google Colab. Candidates are advised to prepare by connecting their projects to meaningful engineering problems and understanding the company's AI safety work.
