Bevel

Bevel is a vendor-agnostic control plane for enterprise AI agents, built by Munich-based Bevelites GmbH (est. 2024). It lets companies define their agents' context, skills, tools, and permissions as plain files stored in their own infrastructure, then serves those definitions to any agent runtime over MCP or UTCP. The core of Bevel, called Hexis, is open source and was launched on Product Hunt.

What It Is

Bevel sits between a company's knowledge and the many AI agent runtimes its employees use — Claude Code, Cursor, ChatGPT desktop, opencode, background server-side agents, and self-hosted models. Instead of locking context, skills, and tool wiring inside each vendor's console or grounding store, Bevel stores everything as plain Markdown and YAML files in a company-owned git repository. Branches, change requests, and diffs are handled by git itself, not rebuilt as proprietary features.

How the Control Plane Works

Four artifacts fully specify an agent in Bevel:

• Context — Typed knowledge nodes with provenance (source, last editor, verification date), compiled into a traversable graph.
• Skills — Procedures written in plain Markdown, readable by process owners and reviewable in a diff.
• Tools & Permissions — Tool manifests with secrets held in a vault; access rules declare which agent may read which file and call which endpoint.
• Identity — Each agent is a named actor with its own credentials and scope, not a shared service account, making every action attributable.

The repository structure follows a conventional layout (knowledge/, skills/, tools/, agents/, access/) and becomes the single source of truth that every connected runtime reads from.

Protocol Layer: UTCP and CodeMode

The Bevel team created the Universal Tool Calling Protocol (UTCP), an open alternative to Anthropic's Model Context Protocol. According to the Bevel website, UTCP has been championed by engineers at AWS, Adobe, Royal Bank of Canada, and MuleSoft. UTCP exposes every capability as a plain HTTP endpoint with no proxy server in the middle. The team's CodeMode library — which the site reports has over 1,500 GitHub stars and 45,000+ downloads — enables agents to chain tools through code execution rather than one call at a time.

Enterprise Deployment Model

Bevel is designed for companies that want to own their agent infrastructure rather than depend on a vendor's harness. The platform targets the "switchover cost" problem: when context, skills, and tool wiring live inside a vendor's product, migrating is extremely costly. With Bevel, the git repository is the source of truth and any compliant runtime can read from it. The site lists customers including Unite Procurement Deutschland AG, Egym SE, Workpath GmbH, Luminovo GmbH, and Avi Medical, and notes supporters including Meta, NVIDIA, Google, CDTM, UnternehmerTUM, Netlight, and EXIST — though these are vendor-published claims on the Bevel homepage.

Update: Hexis Open Source Launch

Bevel announced that Hexis, described as the core of Bevel, is now open source, with a live Product Hunt launch. The UTCP reference implementations and SDKs are also publicly available on GitHub under the universal-tool-calling-protocol organization. This positions Bevel as both an open-source project and a commercial enterprise platform with accompanying professional services.
