Connect an agent to chart knowledge.
Primary interface is MCP Streamable HTTP. Chart source of truth is github.com/chaser100/u-helm-chart. Discovery pointers also live in /llms.txt and /openapi.json.
1. Discover MCP
Public endpoint (anonymous read):
https://helm.networkcat89.com/mcp
Probe index freshness:
curl -sS https://helm.networkcat89.com/healthz
Handshake (JSON-RPC over HTTP POST):
curl -sS https://helm.networkcat89.com/mcp \
-H 'Content-Type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"demo","version":"0"}}}'List tools:
curl -sS https://helm.networkcat89.com/mcp \
-H 'Content-Type: application/json' \
-d '{"jsonrpc":"2.0","id":2,"method":"tools/list"}'2. Cursor mcpServers snippet
{
"mcpServers": {
"helm-networkcat89": {
"url": "https://helm.networkcat89.com/mcp"
}
}
}Paste into Cursor MCP settings (or project MCP config). No token is required for read tools. Write tools need a Bearer token supplied by your operator.
3. Claude / generic HTTP MCP
Point the client at the same URL. Transport: Streamable HTTP. Protocol version advertised by the server: 2025-06-18. Server name: helm-networkcat89.
4. Read tools (anonymous)
search_docs— search chart documentationget_values_schema— values JSON schemaexplain_value— explain a values keylist_examples/get_example— published examplesget_checklist— production checklistlist_shapes/get_shape— workload shapesresolve_resource— resolve ahelm://…URI
Resources are listed via MCP resources/list and read via resources/read (same index).
5. Write tools (Bearer required)
propose_improvement and open_feature_branch_pr create GitHub Issues / mcp/** PRs on chaser100/u-helm-chart. Without Authorization: Bearer … the server returns HTTP 401. Prefer MCP for writes; OpenAPI only documents auth-required stubs.
6. OpenAPI read twin
Non-MCP clients can use the HTTP twin described by /openapi.json. operationId values match MCP tool names. Intended paths live under /api/v1/… (same knowledge index).
