01What can it help you accomplish?
Expose DeepSeek Harness to Multica as a private runtime that discovers models and thinking levels and streams committed text, reasoning, tool, result, and token-usage events
A `multica` DSH profile providing `--probe`, `--list-models`, and `--stdio` surfaces over a versioned JSONL protocol on stdio
Operators and developers who run DeepSeek Harness (dsh) and want a private, out-of-tree Multica bridge that needs no changes to DeepSeek Harness
Translate existing Multica MCP configuration into DSH clients and run long sessions with cooperative cancellation and resume
DSH stdio or streamable-HTTP clients generated from canonical Multica MCP config, with cooperative cancellation, durable session resume, and per-runtime session roots
Platform engineers wiring Multica's MCP tooling into DeepSeek Harness without an interactive approval surface
02How to install into DeepSeek Harness
Prerequisites
- A pnpm-capable Node.js toolchain — the README's local build runs `pnpm install`, `pnpm check`, and `pnpm build`
- The DeepSeek Harness (`dsh`) CLI present on the host — the install step calls `dsh plugin --profile multica add ...`
Installation steps
- 01
Clone the repo and run `pnpm install`, then `pnpm check`, then `pnpm build`
- 02
Install the built bundle into a DSH profile: `dsh plugin --profile multica add /absolute/path/to/multica-dsh-runtime`
$ dsh plugin --profile multica add /absolute/path/to/multica-dsh-runtime
Verify the integration
- Run `dsh --profile multica --probe` — Multica discovers the profile only after `--probe` returns protocol version 1
- Confirm models with `dsh --profile multica --list-models` and open the stdio surface with `dsh --profile multica --stdio`
03DSH integration and capability boundaries
Private, out-of-tree runtime bridge that exposes a versioned JSONL protocol over stdio and composes over @deepseek-ai/dsh-base, with no changes required to DeepSeek Harness.
Versioned JSONL stdio protocol
DeepSeek Harness (dsh) runtime→model and thinking-level discovery plus committed text, reasoning, tool, result, and token-usage events over stdio
Multica MCP to DSH client translation
canonical Multica MCP configuration→DSH stdio or streamable-HTTP clients
Durable sessions with cooperative cancellation
DSH runtime and agent sessions→cooperative cancellation, durable session resume, and per-runtime/agent session roots supplied by the Multica daemon
04Who is it for? When not to use it?
Good for
- Operators and developers who run DeepSeek Harness (dsh) and want a private, out-of-tree Multica bridge that needs no changes to DeepSeek Harness
- Platform engineers wiring Multica's MCP tooling into DeepSeek Harness without an interactive approval surface
Not for
- Never commit API keys, MCP secrets, session logs, or generated profiles; the bundle patch also disables DSH telemetry and keeps stdout protocol-only while routing all diagnostics to stderr.
05Compatibility, maintenance and safety notes
- Never commit API keys, MCP secrets, session logs, or generated profiles; the bundle patch also disables DSH telemetry and keeps stdout protocol-only while routing all diagnostics to stderr.
- This checkout is validated only against `@deepseek-ai/dsh@0.1.0-rc.6` and its matching `@deepseek-ai/dsh-*` package family — other DSH versions are not guaranteed compatible.
- For a non-standard DSH installation, point the daemon at its launcher via `export MULTICA_DSH_PATH=/absolute/path/to/dsh`; Multica only discovers the profile after `--probe` returns protocol version 1.
Multica out-of-tree runtime bridge for DeepSeek Harness; validated against @deepseek-ai/dsh@0.1.0-rc.6; DSH telemetry disabled by bundle patch; no independent safety audit.
06Frequently asked questions
What does dsh-multica-runtime actually do?
It is a private, out-of-tree runtime bridge between Multica and DeepSeek Harness. It exposes a versioned JSONL protocol over stdio, composes over @deepseek-ai/dsh-base, and needs no changes to DeepSeek Harness.
How do I install it into a DSH profile?
Build the bundle with `pnpm install && pnpm check && pnpm build`, then run `dsh plugin --profile multica add /absolute/path/to/multica-dsh-runtime`. Multica discovers the profile only after `dsh --profile multica --probe` returns protocol version 1.
Does it vendor or modify DeepSeek Harness source code?
No. The repo contains only the Multica integration layer and does not vendor or redistribute DeepSeek Harness source code. DSH telemetry is disabled by the bundle patch, and stdout stays protocol-only while diagnostics go to stderr.
Which DSH version is it validated against?
The checkout is currently validated against @deepseek-ai/dsh@0.1.0-rc.6 and its matching @deepseek-ai/dsh-* package family. For a non-standard DSH install, point the daemon at its launcher with `export MULTICA_DSH_PATH=/absolute/path/to/dsh`.
