* MUL-2778 feat(agent): wire mcp_config through OpenClaw runtime The MCP config tab (#3419) lets admins save mcp_config on an agent, and recent work (#3439) plumbed it through the three ACP runtimes. OpenClaw still ignored the field, leaving the Tab silently inert for any OpenClaw-backed agent. Translate the agent's Claude-style `{"mcpServers": {...}}` into the per-task OpenClaw wrapper's `mcp.servers` block — OpenClaw resolves MCP via its own config schema rather than ExecOptions, so the existing OPENCLAW_CONFIG_PATH preparer is the right seam. Fail closed on malformed JSON / entries missing `command` or `url`, matching the fail-closed posture the preparer already uses for the agents.list step. Null / absent mcp_config leaves the wrapper free of an `mcp` key so the user's global mcp.servers flows through untouched; an explicit empty managed set (`{}` / `{"mcpServers":{}}`) is honoured as "admin saved no servers" mirroring `hasManagedCodexMcpConfig`. Strict-mode replacement (drop user-only servers entirely) would require OpenClaw to do a per-key replace rather than a deep merge at `mcp.servers`; the comment documents that caveat rather than relying on undocumented behaviour. Also adds `openclaw` to `MCP_SUPPORTED_PROVIDERS` so the MCP Tab actually surfaces in the agent overview pane, and pins the new visibility case with a renderPane test.

Switch the strict-replace path to write a sanitized snapshot of the user's fully resolved config (via `openclaw config get --json`) with the `mcp` block stripped, then have the wrapper `$include` the snapshot instead of the live user file. With the user's `mcp` gone from the $include resolution, the wrapper's `mcp.servers` is the only definition the embedded OpenClaw sees — managed only, including the explicit empty set. The snapshot lives in envRoot at 0o600 alongside the wrapper so the GC reaper sweeps it with the rest of the task scratch, and no extra OPENCLAW_INCLUDE_ROOTS entry is needed (same-dir $include). Fail-closed on `config get --json` errors so the daemon never silently falls back to the leaky $include path. The inherit branch (null mcp_config) still uses the live user file directly — no extra CLI roundtrip and no snapshot is written. New tests pin the contract Elon's review required: - TestPrepareOpenclawConfigStrictReplacesUserMcpServers: user has global_one + shared, managed has shared + managed_only → wrapper has exactly {shared (managed value), managed_only}; global_one does NOT leak; snapshot file has the user's `mcp` stripped while preserving gateway / providers / API keys. - TestPrepareOpenclawConfigStrictEmptyManagedSetDropsUserMcp: empty managed set drops user's global_one (both `{}` and `{"mcpServers":{}}` cases). - TestPrepareOpenclawConfigNullMcpConfigKeepsUserInclude: null path inherits the live user config, writes no snapshot, makes no extra CLI call. - TestPrepareOpenclawConfigFailsClosedOnResolvedConfigError: errors during `config get --json` surface; no stale wrapper or snapshot. - TestPrepareOpenclawConfigManagedSetFreshInstall: fresh install with managed mcp_config skips the snapshot dance entirely. Also tightens en + zh-Hans MCP Tab copy to mention OpenClaw goes via the per-task wrapper, and to use OpenClaw's own `transport` field rather than Claude's `type` for HTTP/SSE entries. Co-authored-by: multica-agent <github@multica.ai> * MUL-2778 fix(agent): narrow openclaw snapshot strip to mcp.servers only Elon's third-round must-fix: the previous strict-replace snapshot deleted the entire `mcp` block, which wiped out non-server settings under `mcp` like `sessionIdleTtlMs`. Those are documented OpenClaw config keys (https://docs.openclaw.ai/gateway/configuration-reference#mcp) outside the MCP Tab's scope — the agent's saved mcp_config only manages server definitions, so other `mcp.*` tuning the user set must survive. Replace the blanket `delete(resolved, "mcp")` with a stripUserMcpServers helper that: - deletes only `mcp.servers` when `mcp` is an object - drops the parent `mcp` key only when the object is empty after the strip (so we don't emit `mcp: {}` placeholders) - leaves non-object `mcp` values untouched (we only know how to strip servers from the documented shape) Pinned with TestPrepareOpenclawConfigStrictPreservesNonServerMcpKeys: user resolved has both `mcp.sessionIdleTtlMs: 300000` and `mcp.servers.global_one`; after the strict path runs the snapshot keeps the TTL and drops the servers map, and the wrapper's `mcp.servers` is exactly the managed set with no leak.
