dsh-wall-mcp-manager

Running several MCP services under a DeepSeek Harness instance can feel fragile: editing one service description tears down every other stdio child process, credentials linger in plaintext across config layers, and tool contracts are buried in source. dsh-wall-mcp-manager collapses all three problems into a single surface. Its reconcile-style mounting watches a per-instance config fingerprint, so new services connect on save, modified ones reconnect in isolation, removed ones disconnect cleanly, and untouched ones never waver. Credential fields (secretEnv, secretHeaders) are redacted at the dictionary level in every describe response; the UI can only show set or unset, guaranteeing that secrets never leave the host.

The settings page groups tools by their mcp__ prefix and renders each card with call parameters and an unpacked return schema. Shapes that resist field-level expansion (unions, $ref) fall back to the raw JSON rather than guessing. Saving triggers hot-reload; the UI polls for roughly eight seconds until the badge flips from connecting to connected with the registered tool count, or surfaces a concrete failure. A single half-filled entry or an unreachable endpoint only flags that row, never unloading the whole plugin.

Built for DSH developers juggling three or more MCP services who want centralized config, auditable credentials, and at-a-glance tool contracts. The factory default ships with an empty servers map, so installation starts no subprocess and makes no outbound call; services are added at your own pace.
