- **Type-strip host-side, in execution context** — the program is wrapped in an async-function shell, stripped with `node:module`'s `stripTypeScriptTypes` (erasable syntax only — `enum`/namespaces are rejected as a program `exception` and no worker spawns), and sliced back out byte-positioned; it then executes as the body of an `AsyncFunction`, so top-level `await`/`return` work.
|
||||
- **The port assumes a hostile peer** — model code can reach `parentPort` and forge traffic, so every inbound message is shape-validated and REBUILT before anything reads it (`null`, primitives, junk types, and malformed payloads drop without a throw; forged extra fields never ride along), the host answers each call id at most once, resolves binding names as OWN properties only (a forged `constructor` cannot walk a prototype chain), drops post-settlement replies, and converts a non-cloneable binding resolution into an error reply. Forged `log`/`done` messages cannot bypass the caps: one host-side ledger bounds everything that lands in `logs`, and the completion value is re-capped host-side. Worker-side namespaces are null-prototype with `defineProperty`, so `__proto__`-shaped binding names are ordinary keys.
|
||||
- **Two independent budgets, because the peer is hostile** — `computeMs` meters the worker's MEASURED busy time (`worker.performance.eventLoopUtilization()` polling): a hot loop cannot hide behind a pending decoy dispatch, and a program awaiting a slow tool accrues nothing. `maxWallMs` backstops what busy time cannot see (awaiting a promise nobody resolves). Both funnel into `worker.terminate()`, which ends hot synchronous loops too; heap overflow surfaces as the worker's OOM exit (`kind: 'worker-exit'`).
|
||||
- **Logs stream eagerly** — console/stdout/stderr entries cross the port as they happen, so a timed-out or killed program still shows what it printed. ONE shared `maxLogBytes` ledger bounds everything: streamed entries, forged port traffic, and pipe bytes that bypass the patched streams (appended after), with the overflow marked in-band once.

- **Empty environment** — the worker gets `env: {}` and `execArgv: []`: no ambient credentials (stronger than the scrubbed-env rule for spawned commands) and no inherited loader flags.

Source mode loads erasable-only `src/worker.ts` through Node's native type stripping. Built mode passes the sibling `lib/worker.cjs` as a filesystem path because pkg's VFS Worker hook expects CommonJS; the same path works under ordinary Node. `tests/built-lib.e2e.ts` pins the real load path required by [docs/testing.md](../../../docs/testing.md).
|
||||
|
||||
The SDK surface is the default/named `WorkerCodeRuntime` class plus `Config`. The operational `./worker` subpath exists only as the packaged spawn entry; the wire protocol and bootstrap helpers are source-private implementation details.

# @deepseek-ai/dsh-mcp-client
|
||||
|
||||
MCP client bridge plugin: connects to external [Model Context Protocol](https://modelcontextprotocol.io/) servers and registers their tools on `ctx.tools`, making them available to the model as native tools under server-qualified names (`mcp__<serverName>__<rawName>`).
|
||||
|
||||
## Usage
|
||||
|
||||
One plugin instance per MCP server in `cordis.yml`:
|
||||
|
||||
```yaml
|
||||
- id: mcp-github
|
||||
name: '@deepseek-ai/dsh-mcp-client'
|
||||
config:
|
||||
serverName: github
|
||||
transport: stdio
|
||||
command: npx
|
||||
args: ['-y', '@modelcontextprotocol/server-github']
|
||||
env:
|
||||
GITHUB_TOKEN: !!js process.env.GITHUB_TOKEN
|
||||
|
||||
- id: mcp-web
|
||||
name: '@deepseek-ai/dsh-mcp-client'
|
||||
config:
|
||||
serverName: web
|
||||
transport: streamable-http
|
||||
url: http://localhost:3000/mcp
|
||||
headers:
|
||||
Authorization: !!js '`Bearer ${process.env.MCP_TOKEN}`'
|
||||
```
|
||||
|
||||
The model sees `mcp__github__create_issue`, `mcp__web__search`, … — the same server-qualified shape Claude Code and Codex use. HMR hot-swaps: editing the entry triggers disconnect + reconnect without process restart; an unchanged `serverName` reproduces identical tool names.
|
||||
|
||||
## Config
|
||||
|
||||
| Field | Transport | Required | Description |
|
||||
|---|---|---|---|
|
||||
| `transport` | both | yes | `"stdio"` or `"streamable-http"` |
|
||||
| `serverName` | both | yes | Namespace for this server's model-facing tool names; `[A-Za-z0-9_-]{1,32}`, unique across live instances |
|
||||
| `command` | stdio | yes | Executable to spawn |
|
||||
| `args` | stdio | no | Arguments passed to the command |
|
||||
| `env` | stdio | no | Extra env vars merged on top of scrubbed ambient env |
|
||||
| `cwd` | stdio | no | Working directory for the child process |
|
||||
| `url` | http | yes | MCP server URL |
|
||||
| `headers` | http | no | Extra headers (e.g. auth tokens) |
|
||||
| `toolCallTimeoutMs` | both | no | Timeout per `callTool` invocation (default 60000) |
|
||||
|
||||
## Tool naming
|
||||
|
||||
Every MCP tool has two names: the raw MCP name (sent on the wire in `tools/call`) and the public name `mcp__<serverName>__<rawName>` registered on `ctx.tools`. Public names are normalized to the DeepSeek function-name contract (64 chars, `[A-Za-z0-9_-]`); when replacement or truncation changes the name, a deterministic 12-hex-char hash of `(serverName, rawName)` is appended so distinct tools never collapse into one name. Names are pure functions of `(serverName, rawName)` — connection order, re-syncs, and other servers never rename a tool.
|
||||
|
||||
- Two servers publishing the same raw name (e.g. `search`) coexist under their namespaces.
|
||||
- A duplicate `serverName` across live instances fails the later plugin instance at load.
|
||||
- A server listing the same tool name twice is rejected as an invalid tool list.
|
||||
- A foreign registration squatting on this server's namespace rolls back the whole generation (never a partial set), with a loud error.
|
||||
|
||||
## Behavior
|
||||
|
||||
- On connect: `listTools()` → registers each tool via `ctx.tools.register()` under its public name.
|
||||
- Listens for `notifications/tools/list_changed` → re-syncs; a failed re-sync keeps the previous generation registered.
|
||||
- Tool execute: `client.callTool({ name: rawName, arguments }, { signal })` with timeout + abort support — the public name is never sent to the server.
|
||||
- Image content in results is discarded with a placeholder (the harness has no image block type).
|
||||
- On disconnect/crash: all tools are unregistered; no auto-reconnect.
|
||||
|
||||
## Services consumed
|
||||
|
||||
| Service | Usage |
|
||||
|---|---|
|
||||
| `ctx.tools` | Register/unregister MCP tools |
|
||||
|
||||
## Model Experience
|
||||
|
||||
### Discovered MCP tools
|
||||
|
||||
**What the model sees**: After initial discovery succeeds, each advertised MCP tool appears as a native tool named `mcp__<serverName>__<rawName>` (or its deterministic normalized form), with the server-provided description and input schema. A successful re-sync replaces the generation; plugin disposal removes it.
|
||||
|
||||
**Token effect**: Data-dependent schema cost is paid on every request while the tools are registered. Re-sync replaces rather than accumulates schemas, and the server-qualified name adds tokens to every tool definition and call.
|
||||
|
||||
### Tool-call history and results
|
||||
|
||||
**What the model sees**: The public tool name and JSON arguments remain in assistant history. Text result blocks are joined with newlines into one retained text result; image, audio, resource, and unsupported blocks become short placeholders, and MCP `isError` results follow the registry's model-visible error path.
|
||||
|
||||
**Token effect**: Arguments and mapped text are retained until compaction. Binary and resource payloads are discarded rather than added to context.
|
||||
|
||||
## Known Limitations and Deferred Work
|
||||
|
||||
- **Initial discovery is asynchronous** — plugin load does not wait for connection and `listTools()`, so a turn started immediately after boot or HMR can assemble before the MCP tools are registered.
|
||||
- **Tools are the only bridged MCP capability** — Resources and Prompts have no harness consumption surface and are deferred.
|
||||
- **Crash recovery is manual** — transport closure unregisters the server's tools, but reconnect requires an HMR reload or harness restart.
|
||||
- **Non-text results are lossy** — image, audio, and resource payloads are replaced with placeholders, and a structured-only result has no model-visible structured representation.
