Helm MCP

Connects Claude to live Helm chart repositories so it can query actual values.yaml schemas instead of guessing at field names. Exposes five tools: search charts by keyword, list available versions, fetch values with optional JSON path filtering and schema validation, inspect dependencies, and retrieve post-install notes. Works with both HTTP and OCI registries, though OCI requires knowing the chart name upfront since those registries don't support browsing. Useful when you're configuring Kubernetes deployments and need accurate chart documentation without leaving your editor. Ships as a Docker container or standalone binary, supports stdio and HTTP transports, and includes a public rate-limited instance at helm-mcp.kubedoll.com if you want to try it before self-hosting.
