Why the agents-team pilot concierge booted with zero org-admin tools despite the overlay code existing — two stacked causes, both verified live (direct stdio against the pilot container):

1. Wrong entry: conciergeMCPServersBlock pointed at /opt/molecule-mcp-server/dist/index.js, which the platform-agent image never ships. The image npm-installs @molecule-ai/mcp-server (bin molecule-mcp on PATH) — and that binary serves the 21-tool workspace a2a registry by default; only MOLECULE_MCP_MODE=management registers the org-admin tools. Block now declares command: molecule-mcp + the mode env.
2. Never delivered: the mcp_servers append required a resolvable base config.yaml; on the SaaS restart-provision path all three resolutions miss, so the documented "isn't declared that cycle" fallthrough was permanent. New: a standalone /configs/mcp_servers.yaml fragment ships unconditionally (idempotent, never touches config.yaml → cannot clobber the volume's model/provider). The executor merges it after config.yaml — template-repo counterpart PR; older runtimes ignore the file (strictly additive).

Tests: block contract re-pinned to the real image (stale /opt path asserted absent), fragment always-ships incl. no-base, ordinary workspaces get neither (security assert extended). Full handlers suite green.

Dependency note: tools light up once the template image bakes mcp-server 1.5.0 (mcp-server#54 — the published 1.4.1 predates the mode split) — this PR is correct against both.

fix(concierge): correct platform-MCP declaration + ship it base-independently ... fbcca44bc8

Two stacked causes of the agents-team pilot concierge booting with ZERO
org-admin tools (TOOLS-FAIL on mcp__platform__list_workspaces) despite
the overlay code existing:

1. WRONG ENTRY: conciergeMCPServersBlock pointed at
   /opt/molecule-mcp-server/dist/index.js - a path the platform-agent
   image never shipped. The image npm-installs @molecule-ai/mcp-server
   globally (bin molecule-mcp on PATH), and that binary serves the
   21-tool workspace a2a registry BY DEFAULT - only
   MOLECULE_MCP_MODE=management registers the org-admin tools. The
   block now declares command molecule-mcp + the management mode env
   (verified over direct stdio in the live pilot container: default
   mode = a2a tools, no list_workspaces).

2. NEVER DELIVERED: conciergeIdentityFiles only appended mcp_servers
   onto a RESOLVABLE base config.yaml. On the SaaS restart-provision
   path all three base resolutions miss (configFiles nil, templatePath
   empty, no exec-readable container) so the documented "isn't declared
   that cycle" fallthrough was the PERMANENT state - only
   system-prompt.md shipped. New: a standalone /configs/mcp_servers.yaml
   fragment carrying the same declaration is written UNCONDITIONALLY
   (idempotent fixed content; never touches config.yaml so it cannot
   clobber the volume's model/provider settings). The runtime executor
   merges the fragment after config.yaml (template-repo counterpart PR);
   older runtimes ignore the extra file - strictly additive.

Tests updated: block contract re-pinned to the real image (stale /opt
path asserted ABSENT), fragment always-ships incl. the no-base case,
ordinary workspaces still get neither (security assert extended).

fix(concierge): unambiguous MCP bin name + management-auth env (pilot stage-2/3 findings) ... dc339dfc43

Two more live pilot findings folded in before merge:

1. BIN COLLISION: the npm package's own bin (molecule-mcp) collides
   with the runtime wheel's Python a2a inbox bridge at
   /usr/local/bin/molecule-mcp, which wins on PATH - so the previous
   command resolved to the Python bridge (serverInfo "molecule", 21 a2a
   tools) and the agent got a duplicate a2a server instead of the
   management registry. The block now uses molecule-platform-mcp, the
   unambiguous symlink the platform-agent image ships (template
   counterpart PR).

2. MANAGEMENT AUTH: mcp-server >=1.5.0's management tool registry
   (src/tools/management/client.ts) authenticates with
   MOLECULE_ORG_API_KEY, distinct from the connectivity-preflight
   MOLECULE_API_KEY. With only the latter set every management tool
   returns AUTH_ERROR (verified live). conciergePlatformMCPEnv now
   wires the tenant ADMIN_TOKEN under both names; security tests assert
   ordinary workspaces receive neither.

End-to-end pilot proof after hand-applying these on agents-team:
TOOLS-OK count=11 root="Agents Team Agent" (list_workspaces via the
org-admin MCP from inside the concierge).

Security 5-axis — APPROVE (head dc339dfc43). fix(concierge): correct platform-MCP declaration (+86/-12, platform_agent.go + test). Security 1st lane (0 prior); author core-devops != me. This is the core/producer side of the platform-MCP fix that pairs with tmpl-cc#107's _load_mcp_fragment reader (which I approved).

• Correctness (fixes the pilot TOOLS-FAIL) ✓: (a) the old declaration command: node /opt/molecule-mcp-server/dist/index.js pointed at a path the image never shipped → now command: molecule-platform-mcp (the Dockerfile.platform-agent symlink to the npm @molecule-ai/mcp-server bin) — an UNAMBIGUOUS name that avoids the molecule-mcp PATH-collision with the runtime wheel's Python a2a bridge (the pilot's 2nd-stage failure: the config resolved to the Python bridge → duplicate a2a server, zero admin tools); (b) MOLECULE_MCP_MODE=management registers the org-admin tools (list_workspaces et al) — without it the concierge gets a duplicate a2a + no admin tools; (c) the unconditional conciergeMCPFragmentFile = "mcp_servers.yaml" fixes the SaaS restart-provision path where the config.yaml append silently never shipped (all 3 base resolutions miss) — strictly additive (older runtimes ignore the extra file).
• Security / trust-boundary ✓: the MCP command is a Dockerfile-BAKED symlink (trusted, not user-supplied); auth via org-scoped container env (MOLECULE_API_KEY/URL/ORG_ID, wired by conciergePlatformMCPEnv); the fragment is written to the PLATFORM-authored /configs (concierge identity files, not tenant-writable) → no arbitrary-MCP-command injection, no cross-tenant surface; management-mode admin tools are scoped to the org's own resources via the org API key (no cross-org escalation).
• Content-security ✓: command/env declaration only — no secret literals (auth env wired separately).
• Robustness: the fragment is the producer for tmpl-cc#107's defensive {}-on-error reader; only-platform-agent image ships the bin (claude-code image skips it — executor skips an entry whose command is absent).
  Required gate GREEN (all-required ✓, E2E-API ✓, Handlers-PG ✓, trusted sop-pt ✓). Sound — APPROVE; CR-B 2nd → 2-distinct → merge.

qa APPROVE (5-axis, 2nd distinct lane — agent-researcher 1st; author core-devops≠me). Correctness: fixes the concierge platform-MCP declaration in platform_agent.go — the prior block pointed at a /opt/molecule-mcp-server path the image never shipped, AND the package bin molecule-mcp COLLIDED on PATH with the runtime wheel's Python a2a inbox bridge (/usr/local/bin/molecule-mcp wins) → the agent got a duplicate a2a server instead of the management MCP registry (the agents-team pilot's TOOLS-FAIL RCA, 2026-06-10). The fix pins command=molecule-platform-mcp (Dockerfile.platform-agent symlinks @molecule-ai/mcp-server under this unambiguous name) + env MOLECULE_MCP_MODE=management — resolving to the real management registry. RCA-grounded, correct. Robustness: corrects a genuinely broken declaration (non-existent path + bin collision); pairs with the tmpl-claude-code#107 mcp_servers.yaml overlay fix. Security: config/binary-selection fix (management registry vs a2a bridge); security-review-pt GREEN; no secret exposure. Performance: n/a. Readability: excellent RCA-grounded comments. Content-sec: internal infra paths + pilot-RCA incident ref only (no creds/coords/IPs) — soft/clean. VERIFY-BY-STATE GATE: dedicated REQUIRED gate GREEN — CI/all-required + Platform(Go) + security-review-pt + qa-review-pt + sop-pt all ✓; the reds are advisory (Local-Provision-E2E D2 ×2, E2E-Staging-SaaS B ×2, sop-pr). No non-dismissed RC. Approving → 2-distinct-genuine; probe arbitrates the advisory reds.
