DomMCP Public Binary (Starter / Professional / Enterprise)

What is DomMCP

• DomMCP is a read-only MCP server add-in for HCL Domino.
• It provides MCP tools for Domino retrieval, inspection, and operations used by agents and workflow systems.
• This publication is a closed-source binary distribution.

Public editions

• Starter: curated core read-only toolset with tighter runtime limits.
• Professional (licensed): extended read/analysis toolset (query + aggregation + broader capabilities).
• Enterprise (licensed): Professional superset with enterprise entitlement profile and rollout policy.

License model / default runtime behavior

• Without a valid license code, DomMCP runs in Starter mode.
• Technical runtime status for that mode is starter_default_unlicensed.
• In that mode, Starter toolset and Starter caps are enforced permanently.
• Professional and Enterprise capabilities require a valid signed license and remain blocked otherwise.
