Persistent memory using a knowledge graph
Privacy-first. MCP is the protocol for tool access. We're the virtualization layer for context.
Pre-build reality check. Scans GitHub, HN, npm, PyPI, Product Hunt — returns 0-100 signal.
Monitor browser logs directly from Cursor and other MCP compatible IDEs.

A Model Context Protocol (MCP) server for managing multiple Kubernetes clusters. This server provides generic operations for any Kubernetes resource type, plus specialized operations for ServiceExports across multiple configured clusters.
git clone https://github.com/vthapar/subm-mcp-server.git
cd subm-mcp-server
make build
The binary will be created at bin/subm-mcp-server.
make install
Create a configuration file config.yaml:
clusters:
- name: cluster1
kubeconfig: /path/to/cluster1/kubeconfig
context: cluster1-context # optional
- name: cluster2
kubeconfig: /path/to/cluster2/kubeconfig
context: cluster2-context # optional
- name: local
kubeconfig: ~/.kube/config
# Server configuration (optional)
server:
transport: stdio # "stdio" or "http", defaults to "stdio"
http:
host: localhost # defaults to "localhost"
port: 8080 # defaults to 8080
See config.yaml.example for a complete example.
# Using -config flag
./bin/subm-mcp-server -config config.yaml
# Using environment variable
export MCP_K8S_CONFIG=config.yaml
./bin/subm-mcp-server
# Override transport mode via command line
./bin/subm-mcp-server -config config.yaml -transport stdio
The server reads JSON-RPC 2.0 requests from stdin and writes responses to stdout.
# Using config file with HTTP transport
./bin/subm-mcp-server -config config.yaml
# Override via command line flags
./bin/subm-mcp-server -config config.yaml -transport http
# Custom host and port
./bin/subm-mcp-server -config config.yaml -transport http -http-host 0.0.0.0 -http-port 9000
The HTTP server exposes the following endpoints:
POST /mcp - MCP JSON-RPC 2.0 endpointGET /health - Health check endpointlist_clusters - List all configured clusterslist_namespaces - List all namespaces in a clusterget_resource - Get any Kubernetes resource by API version and typelist_resources - List any Kubernetes resources by API version and typeget_serviceexport - Get a specific ServiceExportlist_serviceexports - List ServiceExports in a namespacecreate_serviceexport - Create a new ServiceExport (simple name-based or full manifest)delete_serviceexport - Delete a ServiceExportThe get_resource and list_resources tools work with any Kubernetes resource type:
