About Cosmic MCP Server
Connect your Cosmic bucket to any AI agent and take full control of your AI-powered headless CMS and digital content workflows through natural conversation.
LangChain's ecosystem of 500+ components combines seamlessly with Cosmic through native MCP adapters. Connect 10 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Object Management — List, retrieve, and create CMS objects across your buckets, allowing you to drop formatted JSON payloads feeding strictly verified metadata trees
- Content Mutation — Safely update existing objects by patching title and metadata blocks, substituting draft values natively through the REST API
- Schema Auditing — Enumerate active object types and retrieve structural extraction of properties to verify exactly what fields and metadata the schema requires
- Media Oversight — Inspect deep internal arrays of uploaded media, track imgix endpoints, and resolve explicit file metadata for seamless asset management
- Bucket Cleanup — Irreversibly vaporize explicit app nodes and wipe media assets to manage storage quotas and clear up internal database allocations
- Environment Navigation — Identify bounded routing spaces inside your headless environments and switch between different content models (type slugs) easily
The Cosmic MCP Server exposes 10 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
