What is dsh-mcp-panel?

The MCP management console for the official DeepSeek Harness MCP client — add, edit, remove, and trial-call MCP servers from a settings page, with honest status, health diagnostics, and safe, reversible profile writes.

Official client = bridge, this plugin = console: read status through the mcp/status seam, write only append-only, approval-gated profile patches.

The same run, animated.

Compatibility

| Surface | Status | |---|---| | Harness | DeepSeek Harness dsh-v0.2.1-alpha.1 (verified 2026-09-25): dual typecheck rulers green on the 0.1.6-alpha.2 dev/test face (this repo is the family's canary — no new errors surfaced), 174 tests, and the full gate chain (typecheck / typecheck:ci / test / build / verify / package). The writePatch re-verification assertion stands on this line. Previous baseline: dsh-v0.1.7-alpha.1 (verified 2026-09-16). | | Node | ^22.19.0 \|\| >=24.0.0 | | Platforms | Web GUI (dual-face: host + browser) | | Model | Any (the panel is read-only; only /mcp output is model-readable) |

What you get

dsh-mcp-panel is the experience layer on top of the official MCP client: a read-only runtime view plus safe, reversible profile writes.

• /mcp command — one row per server: transport, target, tool count, connection status (from the upstream seam; unknown when unobserved), last error, reconnect count — model-readable, session-log reconstructable, five output languages.
• /mcp <server> tools — model-visible mcp__* tool names and descriptions.
• /mcp <server> health — derived self-heal suggestions (ENOENT → missing dependency, ECONNREFUSED, timeouts, 401/403/404, DNS, rate limit, reconnect exhaustion…); exit code / stderr tail honestly labeled pending upstream support until the client exposes them.
• /mcp <server> disable / enable — turn one server row off or back on without editing the profile patch by hand.
• /mcp <server> probe — one Streamable HTTP connectivity probe for that server (background job).
• /mcp <server> call <tool> [json] — trial-call through the official tool pipeline (ctx.tools.execute()); pre-execute permission policy, approval, guards, and post-execute all apply.
• Settings → Plugins → MCP tab — status cards with badges, diagnostics, and probes, plus the server CRUD and the tool trial console.
• Server CRUD — add/edit/remove forms → insert for add and id-targeted overrides (- id: + name: + disabled:/config:) for edit/remove → clipboard copy or approval-gated write with automatic backups and loader re-verification.
• Resources browse — read-only resource listing, template listing, and URI reads through the official list_mcp_resources / list_mcp_resource_templates / read_mcp_resource tools (bridged by the shipped @deepseek-ai/dsh-mcp-resources service); results are shown in the tab only, never in model context.
• Recommended directory — a built-in community MCP server catalog (filesystem, git, github, fetch, playwright, …) served in the snapshot; catalogEntries appends/overrides entries, and catalogToConfigInput turns one into a one-click add.
• Config import/export — exportConfigs() serializes the server rows to a versioned JSON document (a !!js row exports as null with a reason), and importPreview() parses an export back into per-server add patch fragments for review.
• Tool trial console — server → mcp__* tool → JSON args → canonical JSON result + rendered content; capped by trialMaxResultChars; panel-only, never model context.

Architecture: official client = bridge, this plugin = console

@deepseek-ai/dsh-mcp-client is the only bridge: one plugin instance per MCP server, configured as a hand-written cordis.yml row, connecting the transport, syncing tools, and registering mcp__<server>__<tool> names. This plugin never replaces it — it is the experience layer on top:

The console reads the client through its proposed mcp/status observability seam (not yet shipped upstream; feature-detected) (event + mcpStatus query service), the tool registry, and the loader; it writes only the profile's patch layer — append-only, approval-gated, always backed up. Transport, OAuth, and protocol stay untouched.

Console vs. hand-written cordis.yml

| | Hand-written cordis.yml | dsh-mcp-panel console | |---|---|---| | Add a server | Edit YAML, mind indent/quoting | Form → patch fragment → copy or write (approval + auto backup) | | Edit a server | Edit YAML, restart/hot-reload | Form pre-filled from the live row; unchanged secrets keep their raw values host-side | | Remove a server | Delete the row | - id: + disabled: true override (the patch vocabulary has no remove) — re-enableable anytime | | See status | Read logs | Badges + reconnects + last error, live from the mcp/status seam | | Try a tool | Ask the model to call it | Trial console → official ctx.tools.execute() pipeline (permission & approval stay in force) | | Diagnose failures | Grep logs | /mcp <server> health with derived self-heal suggestions | | Mistakes | Manual revert | Every write is append-only and leaves a timestamped backup |

The console's output IS cordis.patch.yml vocabulary — the same lines you would write by hand, generated, previewed, and applied safely.

Quick start

dsh plugin --profile web add github:PerryLink/dsh-mcp-panel

# 1. install the bundle into your profile
dsh plugin --profile web add github:PerryLink/dsh-mcp-panel

# or from npm (published releases)
dsh plugin --profile web add dsh-mcp-panel

# 2. restart and verify the row
dsh --profile web --dump-config | grep -A3 'id: mcp-panel'

Then open Settings → Plugins → MCP, or run:

/mcp
/mcp everything tools
/mcp everything health
/mcp everything call echo '{"message": "hi"}'

Install & uninstall

• git channel (latest main): dsh plugin --profile web add github:PerryLink/dsh-mcp-panel — the prepare script builds with production dependencies only.
• npm channel (published releases): dsh plugin --profile web add dsh-mcp-panel.
• tarball channel: pnpm pack in this repo, then dsh plugin --profile web add ./dsh-mcp-panel-<version>.tgz.
• uninstall: remove the mcp-panel row from cordis.patch.yml (the web surface hot-reloads it), delete the package from the profile's node_modules, and verify with dsh web --dump-config that no mcp-panel row remains.

Configuration

All tunables are Schemastery Config fields (changeable from cordis.yml). cordis.patch.yml documents the common keys inline; the full key list lives in the table below.

| Key | Default | Meaning | |---|---|---| | probeEnabled | true | Register the mcp_probe background-job tool (panel-only results) | | probeTimeoutMs | 10000 | Per-probe timeout in ms | | maxProbes | 10 | Probe records shown in the panel | | refreshIntervalMs | 0 | Suggested panel refresh in ms; 0 = on demand | | outputLanguage | en | /mcp output language: en \| zh \| es \| pt \| hi | | passiveProbeEnabled | false | Periodically probe streamable-http servers | | passiveProbeIntervalMs | 60000 | Passive probe interval in ms | | trialEnabled | true | Tool trial console (settings tab + /mcp call) | | trialTimeoutMs | 120000 | Panel-side deadline per trial call in ms | | trialMaxResultChars | 60000 | Cap on the trial result payload in chars | | writeEnabled | true | Kill switch: false rejects every profile write (copy still works) | | writeVerifyEnabled | true | Re-verify each write against the loader's re-applied state before reporting success | | writeVerifyTimeoutMs | 3000 | Polling budget for write verification in ms | | backupCount | 5 | cordis.patch.yml backups retained per write | | catalogEntries | [] | User overlay for the recommended server directory: entries append, an entry with the same id replaces the built-in one |

Tools & surfaces

| Surface | Kind | Notes | |---|---|---| | /mcp | command | Per-server status row; model-readable and log-reconstructable | | /mcp <server> tools | command | Model-visible mcp__* tool names + descriptions | | /mcp <server> health | command | Derived self-heal suggestions from sanitized error text | | /mcp <server> disable / enable | command | Toggle one server row in the profile patch | | /mcp <server> probe | command | One Streamable HTTP connectivity probe (background job) | | /mcp <server> call <tool> [json] | command | Trial-call through the official tool pipeline | | mcp_probe | tool | Optional Streamable HTTP connectivity probe (background job) | | Settings → Plugins → MCP tab | UI slot | Status cards, server CRUD, and the tool trial console | | mcpPanel Typert Remote | service | Read-only snapshot channel (host → client) |

Resources & Prompts

Resources ARE bridged upstream: the base bundle mounts @deepseek-ai/dsh-mcp-resources, the official client registers each connection's resource provider into ctx.mcpResources, and that package owns the three shared tools (list_mcp_resources, list_mcp_resource_templates, read_mcp_resource). The console feature-detects the service and the registered tools, and offers a read-only Resources browser (list / templates / URI read) on every server card — each call runs through the OFFICIAL tool pipeline, and results never enter model context.

MCP prompt templates and resource subscriptions remain deferred upstream; the capabilities board marks Prompts pending upstream support.

Permissions & data

• Permissions: the dshWorkshop manifest declares network:outbound and native-code:none.
• Data: the panel is read-only; it writes only append-only cordis.patch.yml fragments (approval-gated, backup-first). URL query credentials, userinfo passwords, header values, bearer tokens, and JWTs are redacted before rendering; configured headers never enter any snapshot, and env/header values never leave the host (the editor sees keys only).

Security boundaries

• The bridge stays the bridge. No transport, OAuth, or protocol changes; one mcp-client row per server, exactly as hand-written.
• No fake status. Connection fields without upstream observations read unknown / — with statusSource: 'derived'; exit codes and stderr tails are never invented.
• Writes are append-only, approval-gated, and backed up. The console never rewrites cordis.patch.yml; it appends generated operations, keeps the newest backupCount backups, and re-verifies every write against the loader's re-applied state before reporting success (a skipped patch never reads as success).
• No prompt injection. The panel registers no prompt sections; its only model-facing text is the two tool/command descriptions.

Known limitations

• Prompt templates & resource subscriptions are pending upstream support — the official client bridges tools and resources, but not prompts or subscriptions.
• Exit codes / stderr tails are labeled pending upstream support until the client exposes them.
• Read-only panel — the console never fakes a connection state; unobservable fields read unknown / -1 / —.
• Writes are verified, not guaranteed — the console re-verifies each write against the loader's re-applied state and fails honestly when the loader did not apply it (e.g. a row inserted by $DSH_HOME/cordis.patch.yml, which a profile-layer patch cannot reach).

Development

pnpm run typecheck && pnpm run typecheck:ci && pnpm test && pnpm run build && pnpm run verify:self-contained && pnpm run verify:artifacts && pnpm pack

scripts/verify-headless.mjs boots the real web profile and prints the exact /mcp output. Releases: node scripts/release.mjs <x.y.z> runs the full gate, commits, and tags v<x.y.z> locally (never pushes).
