How do I install Shardflux?

Copy the http config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Shardflux need an API key?

The publisher lists these environment variables: SHARDFLUX_API_KEY, SHARDFLUX_API_URL, SHARDFLUX_WORKSPACE_KEY, SHARDFLUX_TEMPLATE, SHARDFLUX_MCP_TOOL_TIMEOUT_MS, SHARDFLUX_WAKE, SHARDFLUX_WAKE_TIMEOUT_MS, SHARDFLUX_AGENT_LABEL, SHARDFLUX_MCP_LOG_LEVEL, SHARDFLUX_HTTP_KEEPALIVE, SHARDFLUX_PREWAKE.

What transport does Shardflux use?

Shardflux is reached over HTTP.

Shardflux

Credentials from the publisher

SHARDFLUX_API_KEY — Scoped Shardflux project API key (sfk_<key id>_<secret>). Its tool permissions decide which workspace tools are listed.
SHARDFLUX_API_URL — API base URL. Plain http:// is allowed only for loopback hosts.
SHARDFLUX_WORKSPACE_KEY — Pin one workspace: workspace_key becomes optional on every tool and any other key is refused (workspace_pinned).
SHARDFLUX_TEMPLATE — Default template slug for workspace_open.
SHARDFLUX_MCP_TOOL_TIMEOUT_MS — Default and maximum deadline per tool call in milliseconds (1000-3600000). A call's timeout_ms can only shorten it.
SHARDFLUX_WAKE — on: workspace tools resume a suspended workspace and then run. off: they return the workspace_not_running refusal.
SHARDFLUX_WAKE_TIMEOUT_MS — Longest wait per tool call for a workspace to wake or finish a transition, in milliseconds (1000-3600000; clamped to SHARDFLUX_MCP_TOOL_TIMEOUT_MS).
SHARDFLUX_AGENT_LABEL — Attribution label of every tool token this server obtains (shown as an agent session).
SHARDFLUX_MCP_LOG_LEVEL — Log level of the JSON log lines on stderr (stdout carries the protocol).
SHARDFLUX_HTTP_KEEPALIVE — Unset: private HTTP/1.1 pooling on Node 26, native fetch elsewhere. 0: force connection closure for diagnosis. 1: select native pooling.
SHARDFLUX_PREWAKE — Offer explicit workspace_hint for tool input streaming (on or off).
