What is deepseek-subagent-mcp CLAUDE.md?

A set of Claude Code instructions for an MCP server that lets other MCP clients delegate work to DeepSeek Harness, an open-source agent runtime. It also supervises the delegated agent and returns a checked result with a concise handoff.

Use it to start, wait for, continue, list, cancel, and inspect delegated agent runs. Local tests cover the server and its safeguards; live runs require a DeepSeek API key and use paid API tokens.

It helps separate delegated work from the main agent while controlling tool calls and managing the child process. It provides a completion result instead of requiring the client to interpret a full raw transcript.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

deepseek-subagent-mcp CLAUDE.md scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

An MCP server that exposes DeepSeek Harness (dsh, DeepSeek's open-source agent runtime, released 2026-08-13, MIT) as a delegatable subagent to Claude Code, Codex, or any other MCP client. Six tools: dsh_delegate, dsh_await, dsh_continue, dsh_list, dsh_cancel, dsh_transcript.

It ships four things upstream does not: a hardened plugin composition, an external supervision layer that gates the child's tool calls, process-lifetime management the wire protocol cannot provide, and a result contract — verified completion and a distilled handoff rather than a raw transcript.

Commands

uv sync
uv run pytest                                     # 153 unit tests, no API key, no network
uv run ruff check .
uv run pytest tests/test_guard.py -q              # the classifier alone
uv run pytest tests/test_runs.py::test_run_deadline_kills_the_agent
uv build
uv run deepseek-subagent-mcp                      # stdio; a client drives it

Live smokes cost real tokens, need DEEPSEEK_API_KEY, and are not collected by pytest. Run them by path after touching runs.py, server.py, guard.py, verify.py, supervisor.py, or the YAML:

DEEPSEEK_API_KEY=sk-... uv run python tests/smoke_mcp.py        # all 6 tools over stdio
DEEPSEEK_API_KEY=sk-... uv run python tests/smoke_task.py       # real file writes, 2-turn session
DEEPSEEK_API_KEY=sk-... uv run python tests/smoke_result.py     # distillation, cap, run archive
DEEPSEEK_API_KEY=sk-... uv run python tests/smoke_limits.py     # reaper + run deadline
DEEPSEEK_API_KEY=sk-... uv run python tests/smoke_supervisor.py # allow/deny through the hook
DEEPSEEK_API_KEY=sk-... uv run python tests/smoke_escalation.py # sampling + elicitation tiers

smoke_supervisor.py is the one that proves the security story. smoke_task.py proves the product works. smoke_result.py proves the caller gets a result rather than a transcript.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
