Multitenant Streamable HTTP bridge over nutanix/ntnx-api-mcp-server — Nutanix's official Prism Central v4 API MCP server — built so the WYRE conduit gateway can forward per-tenant Nutanix credentials as HTTP headers.
Upstream pin: Nutanix's server is a technical preview, pinned here at tag `v0.8` (Apache-2.0). See Bumping the upstream pin.
The upstream server is stdio-only (nutanix-mcp serve-stdio is its only serve mode) and reads its Prism Central credentials from environment variables at process startup — single-tenant per process. Our gateway is multi-tenant: every request carries the calling org's credentials as HTTP headers, and the vendor container has to translate those headers into something the upstream understands.
Because the upstream has no HTTP mode to proxy to, this bridge holds an MCP client session over stdio to each tenant child and re-serves it over Streamable HTTP:
:8080 with POST /mcp and GET /health. Startup requires a real CONDUIT_S2S_SECRET. Every /mcp request must carry a valid X-Gateway-S2S signature of that secret./mcp request on the X-Nutanix-Pc-* credential headers (below). Those headers are the only Prism Central credential source.nutanix-mcp serve-stdio child per credential tuple (keyed by a hash), with the tenant's PC_* env vars set, and connects an MCP client to it over stdio./mcp via the v2 SDK's createMcpHandler(factory, { legacy: 'stateless' }) — 2025-era initialize-handshake clients (the conduit gateway today) and modern 2026-07-28 envelope clients. tools/list and tools/call delegate to the tenant's child session.IDLE_EVICT_MS).Tool names pass through unchanged: the upstream's 24 tools — 20 {namespace}_execute tools (aiops, clustermgmt, datapolicies, dataprotection, files, iam, licensing, lifecycle, microseg, monitoring, multidomain, networking, objects, opsmgmt, prism, security, storage, tenancy, vmm, volumes) plus 4 discovery tools (listOperations, getOperationSchema, getCodeSample, getOperationPermissions).
Every child is spawned with `READ_ONLY_MODE=true` (also the upstream default): the upstream rejects all non-GET operations before they ever reach Prism Central. v1 of this bridge ships read-only as a deliberate fleet decision. Write support would be a reviewed, versioned change to credentialsToChildEnv() in src/credentials.ts — not a config flip.
The gateway forwards these headers on every /mcp request; the bridge maps them onto the upstream child's environment. conduit's vendor-config must match this table exactly.
| Header | Child env var | Required | Notes |
|---|---|---|---|
X-Nutanix-Pc-Host | PC_HOST | yes | Prism Central IP or FQDN |
X-Nutanix-Pc-Port | PC_PORT | no | Upstream default 9440. Upstream quirk: any port other than 9440 makes it use http://, not https:// |
X-Nutanix-Pc-Username | PC_USERNAME | with password | Basic auth pair |
X-Nutanix-Pc-Password | PC_PASSWORD | with username | Basic auth pair |
X-Nutanix-Pc-Api-Key | PC_API_KEY | alternative | Sent to PC as the X-ntnx-api-key request header; upstream prefers it over basic auth when both are set |
X-Nutanix-Pc-Insecure | PC_INSECURE | no | "true"/"false" — skip TLS verification (default false) |
Validity rule: pcHost present AND (apiKey present OR username+password present). Anything else → HTTP 401 with a JSON-RPC error body.
READ_ONLY_MODE=true is additionally forced on every child (see above).
The upstream builds its tool surface from YAML API-spec artifacts, not from the live PC. nutanix-mcp init downloads them — and without PC credentials it runs in latest_release mode against the public developers.nutanix.com namespace API (no PC access required; verified empirically: 20 namespaces). The Docker build runs init once and bakes the artifacts into the image at /opt/nutanix-mcp/artifacts, shared read-only by all tenant children. Consequences:
tools/list and the discovery tools work with no reachable PC — only {namespace}_execute calls touch Prism Central.pc_compatible mode would need live PC access at spawn). For the read-only v1 surface this is the right trade: shared artifacts, fast tenant spawns.Copy .env.example. Leave CONDUIT_S2S_SECRET empty in that file and set a real value only in the environment you run.
| Env var | Default | Notes |
|---|---|---|
CONDUIT_S2S_SECRET | empty (refuses to start) | Service-to-service secret. The HTTP server logs an error and exits non-zero when this is empty or a known placeholder (changeme, secret, replace-me, your-s2s-secret, replace-with-a-real-secret, and the other example values). Generate one with openssl rand -hex 32. Compose will not start without it. The value is never logged. |
MCP_ALLOW_INSECURE_DEV | unset | Set to exactly 1 only for local development to start HTTP without CONDUIT_S2S_SECRET. The process logs a warning, skips X-Gateway-S2S, and binds 127.0.0.1 only. A non-loopback MCP_HTTP_HOST refuses to start. A known placeholder secret still refuses to start. |
MCP_HTTP_HOST | 0.0.0.0 when a real secret is set | Bind address. A configured secret honors this value, including when it is unset (historical 0.0.0.0 container bind). The image and Compose set 0.0.0.0 inside the container. With no secret, MCP_ALLOW_INSECURE_DEV=1 binds 127.0.0.1 only. |
PORT | 8080 | Public listen port (MCP_HTTP_PORT is the fallback). |
NUTANIX_MCP_DIR | /opt/nutanix-mcp | Upstream checkout (venv + artifacts). |
NUTANIX_MCP_BIN | $NUTANIX_MCP_DIR/.venv/bin/nutanix-mcp | Upstream console script the bridge spawns. |
ARTIFACTS_DIR | $NUTANIX_MCP_DIR/artifacts | Baked YAML API-spec artifacts. |
CHILD_LOG_DIR | /tmp/nutanix-mcp-logs | Writable dir for upstream per-process log files. |
IDLE_EVICT_MS | 3600000 | Idle tenant timeout (60 min). |
SPAWN_TIMEOUT_MS | 60000 | Max wait for a child to answer the MCP handshake. |
/health and /healthz stay unauthenticated and do not read credentials.
With CONDUIT_S2S_SECRET set, every /mcp request must include X-Gateway-S2S. The check is verifyS2sHeader in src/s2s-verify.ts: the header value is t= ,v1= , where the hex is HMAC-SHA256 of the literal string t= keyed with CONDUIT_S2S_SECRET (64 lowercase hex characters). The timestamp must be within 300 seconds of the server clock. A missing or invalid header is HTTP 401, before Prism Central credentials are read.
Sign with the same CONDUIT_S2S_SECRET the server process is using. Local development exports that value in the shell; reuse it for this request instead of generating another one.
TS=$(date +%s)
SIG=$(printf 't=%s' "$TS" | openssl dgst -sha256 -hmac "$CONDUIT_S2S_SECRET" -hex | awk '{print $NF}') curl -sS http://127.0.0.1:8080/mcp \ -H 'Content-Type: application/json' \ -H 'Accept: application/json, text/event-stream' \ -H "X-Gateway-S2S: t=${TS},v1=${SIG}" \ -H 'X-Nutanix-Pc-Host: pc.example.com' \ -H 'X-Nutanix-Pc-Api-Key: fake' \ -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"dev","version":"0"}}}'
This bridge is gateway mode. /mcp also requires X-Nutanix-Pc-Host and either X-Nutanix-Pc-Api-Key or both X-Nutanix-Pc-Username and X-Nutanix-Pc-Password. Those headers are the only credential source for that request. PC_* values in the process environment are not used as a fallback.

curl -s localhost:8080/health
Or build the image (it bakes everything, including a stdio smoke test that fails the build if serve-stdio can't answer tools/list). The image listens on 0.0.0.0 inside the container and still refuses to start without a real CONDUIT_S2S_SECRET. Publish the port on loopback. Prism Central credentials arrive on each request as X-Nutanix-Pc-* headers.
docker build --platform linux/amd64 -t ghcr.io/wyre-ai/nutanix-mcp:dev .
docker run --rm \ -e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \ -p 127.0.0.1:8080:8080 \ ghcr.io/wyre-ai/nutanix-mcp:dev
Compose refuses to start when CONDUIT_S2S_SECRET is unset. The gateway service publishes 127.0.0.1:8080:8080 and does not inject PC_HOST, PC_USERNAME, PC_PASSWORD, PC_API_KEY, or env_file. Use the exported secret so a later signing request matches the container:
