Delivers the final piece of the mcptoken stack: a containerized,
network-accessible mcplocal that serves Streamable-HTTP MCP to off-host
clients (the vLLM use case), authenticated by project-scoped McpTokens.
New binary (same package, new entry):
- src/mcplocal/src/serve.ts — HTTP-only entry. Reads MCPLOCAL_MCPD_URL,
MCPLOCAL_MCPD_TOKEN, MCPLOCAL_HTTP_HOST/PORT, MCPLOCAL_CACHE_DIR from
env. No StdioProxyServer, no --upstream.
- src/mcplocal/src/http/token-auth.ts — Fastify preHandler that
validates mcpctl_pat_ bearers via mcpd's /api/v1/mcptokens/introspect.
30s positive / 5s negative TTL. Rejects wrong-project with 403.
Shared HTTP MCP client:
- src/shared/src/mcp-http/ — reusable McpHttpSession with initialize,
listTools, callTool, close. Handles http+https, SSE, id correlation,
distinct McpProtocolError / McpTransportError. Plus mcpHealthCheck
and deriveBaseUrl helpers.
New CLI verb `mcpctl test mcp <url>`:
- Flags: --token (also $MCPCTL_TOKEN), --tool, --args (JSON),
--expect-tools, --timeout, -o text|json, --no-health.
- Exit codes: 0 PASS, 1 TRANSPORT/AUTH FAIL, 2 CONTRACT FAIL.
Container + deploy:
- deploy/Dockerfile.mcplocal (Node 20 alpine, multi-stage, pnpm
workspace, CMD node src/mcplocal/dist/serve.js, VOLUME
/var/lib/mcplocal/cache, HEALTHCHECK on :3200/healthz).
- scripts/build-mcplocal.sh mirrors build-mcpd.sh.
- fulldeploy.sh is now a 4-step pipeline that also builds + rolls out
mcplocal (gated on `kubectl get deployment/mcplocal` so the script
stays green before the Pulumi stack lands).
Audit + cache:
- project-mcp-endpoint.ts passes MCPLOCAL_CACHE_DIR into FileCache at
both construction sites and, when request.mcpToken is present, calls
collector.setSessionMcpToken(id, ...) so audit events carry the
tokenName/tokenSha.
Tests:
- 9 unit cases on `mcpctl test mcp` (happy path, health miss,
expect-tools hit/miss, transport throw, tool isError, json report,
$MCPCTL_TOKEN env fallback, invalid --args).
- Smoke test src/mcplocal/tests/smoke/mcptoken.smoke.test.ts —
gated on healthz($MCPGW_URL), skipped cleanly when unreachable.
Covers happy path, wrong-project 403, --expect-tools contract
failure, and revocation 401 within the negative-cache window.
1773/1773 workspace tests pass. Pulumi resources (Deployment, Service,
Ingress, PVC, Secret, NetworkPolicy) still need to land in
../kubernetes-deployment before the smoke gate flips on.
