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.

License activation

• Insert signed license code into config key license.license_code.
• Restart add-in.
• Validate runtime/licensing tools.

domino cmd "tell dommcp quit"
domino cmd "load dommcp_addin /local/notesdata/<config>.json"

Supported platform

• Linux x86_64 (ELF 64-bit add-in binary).
• Built against Domino C API on Linux.
• Requires HCL Domino 14.5 (runtime and API compatibility target for this release line).
• glibc requirement: use the binary matching your target host (glibc 2.34 or glibc 2.38).
• Detect host glibc before choosing the artifact:
  • ldd --version | head -n 1

Known prerequisites / constraints

• Domino server runtime must match released binary requirements.
• Domain binding in runtime config must match signed license claims.
• MCP listen host/port must be reachable from clients.
• Public toolset is read-only by design.
