dsh-mcp-servers

Standalone development home for the DeepSeek Harness MCP plugins. These packages were extracted from the deepseek-harness monorepo so the MCP plugin stack can be developed, tested, and published on its own. The harness checkout keeps its own copies; this repository is the independent source of truth going forward.

Packages

examples/mcp-memory/ holds the default-off reference overlays that connect memory servers through the generic MCP client.

Requirements

• Node ^22.19 || >=24
• pnpm 11

Develop

pnpm install
pnpm build       # tsc -b + tsdown runtime bundles + ui client bundle
pnpm test        # vitest unit + keyless e2e suites
pnpm clean       # remove lib/ and build state

Install and use

The packages publish to npm under the @deepseek-ai scope. Install the ones you need in a DSH profile, then reference them from a cordis.patch.yml layer exactly as the harness does — for example, connect a memory server with one of the shipped overlays:

dsh web --patch "$PWD/examples/mcp-memory/memorix.cordis.yml"

No MCP server is enabled by default: every server command is trusted executable code outside the agent sandbox, so each connection is an explicit configuration. See each package README for its config schema and model-facing behavior.
