@mcp-abap-adt/compact-readonly-entries

Compact read-only tools — 16 tools that change nothing.

A library, not a server. To run the compact server, install @mcp-abap-adt/compact (mcp-abap-adt-compact); to run a server of these 16 tools alone, @mcp-abap-adt/compact-ro (mcp-abap-adt-compact-ro, and -compact-http-ro, -compact-sse-ro); see Installation variants.

Renamed in 19.0.0 from @mcp-abap-adt/compact-readonly, so it is not confused with @mcp-abap-adt/compact-ro, the server. The exports are unchanged.

What compact is

A different decomposition of the same ABAP ADT surface: the operation is the tool and the object moves into the arguments. Where the object-oriented surface has CreateClass, CreateDomain, CreateDdl and so on, compact has one HandlerCreate with object_type. Twenty-seven tool schemas instead of hundreds. Each object_type enum, and each tool's description, is the declared system type's: its members are those the system type's ADT type table serves (22.0.0) — on cloud the writes offer no PROGRAM and no INCLUDE — and a member outside them is refused naming the list, before anything is sent.

It exists for a host that cannot build a retrieval pipeline of its own — a small context, no tool-RAG, no way to select tools per request — and must still drive ABAP through MCP reliably. A consumer that does select per request (cloud-llm-hub, for one) has no use for it and should take @mcp-abap-adt/lib instead.

Why two library packages

Capability is decided by what you import, not by a flag a caller can pass. A tool list assembled from @mcp-abap-adt/compact-readonly-entries has no route to a write handler in its module graph — asserted against the graph, not against a list of names, in compact/src/__tests__/compactCapabilitySplit.test.ts. The read-only half depends on @mcp-abap-adt/lib/handlers/read; the modifying half on @mcp-abap-adt/lib/handlers/write.

Note what this is not: both halves depend on @mcp-abap-adt/lib, so this is not a smaller install, and it is not a sandbox — code that deliberately reaches into lib can still call anything. It is a facade that offers no way to write.
