Describes the environment variables required to run the server.

Name	Required	Description	Default
`MCP_GDS_RUNTIME`	No	Execution runtime for tools. Set to 'host' to force host binaries instead of container (Podman) execution.	podman

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

This server publishes no instructions, or was last inspected before Glama recorded them.

Functions exposed to the LLM to take actions

Name	Description
gds_infoA	Reads GDSII/OASIS layout metadata headlessly (cells, top cells, bounding boxes, per-layer shape counts). Pure introspection, no PDK needed. Use when you need to know what is inside a layout file.
gds_stream_outA	Streams a DEF layout to GDSII via headless KLayout using Nangate45 LEFs (abstract cell footprints; full transistor GDS needs the PDK). Use to produce DRC input or handoff previews, not tapeout signoff.
drc_klayoutA	Runs KLayout batch DRC on a GDS file. Default is a generated generic width/space smoke deck over the layout's own layers (geometry sanity, not foundry signoff). Pass deck_file for a real PDK rule deck. Does not do LVS; use lvs_netgen for netlist comparison.
lvs_netgenA	Compares two SPICE netlists with Netgen batch LVS and reports match/mismatch with net/device counts. Compares netlists only; use extract_magic to derive a layout netlist first. Does not do DRC.
extract_magicA	Extracts a SPICE netlist from layout with Magic batch mode (ext2spice lvs). Runs on generic technology: correct flow plumbing, but device-accurate extraction needs a PDK tech file.
gds_toolchain_infoA	Returns active container/host runtime and versions of KLayout, Magic, and Netgen.
