## Tool descriptions

- `openroad_power` — Reports power (total/internal/switching/leakage watts plus per-group breakdown) for a placed or routed DEF via OpenSTA report_power. True IR-drop needs PSM, absent in OpenROAD 2.0.
- `openroad_cts` — Runs clock tree synthesis (CTS) on a placed DEF file, reporting inserted clock buffers/nets and post-CTS timing slack.
- `openroad_detail_route` — Runs detailed routing on a globally-routed DEF file and reports DRC issue counts with samples. Completes even with findings; check drcIssues before signoff.
- `openroad_floorplan` — Initializes ASIC floorplan boundaries, core/die sizing, and I/O pin placement using OpenROAD, generating a floorplan DEF file.
- `openroad_pdn` — Inserts a stdcell power grid (followpins rails + upper-layer straps). Sky130 only. The step tool takes a placed DEF; inside openroad_pnr, PDN runs after floorplan/tap and before place so GPL sees straps. Platforms without PDN config erro…
- `openroad_place` — Performs standard cell global analytical placement (RePLace) and legalized detailed placement (DPL) on a floorplan DEF file.
- `openroad_pnr` — Performs end-to-end automated digital ASIC physical design (floorplanning, placement, routing, and static timing analysis) on a gate-level netlist using OpenROAD, returning area, utilization, wirelength, and timing slack metrics.
- `openroad_route` — Performs global routing (FastRoute) on a placed DEF file, reporting wirelength estimates. Use openroad_detail_route afterwards for detailed routing with DRC reporting.
- `openroad_sta` — Performs static timing analysis using OpenSTA on placed or routed DEF files, reporting Worst Negative Slack (WNS), Total Negative Slack (TNS), and critical paths.
- `openroad_sta_corners` — Runs static timing analysis across multiple Liberty corners (one .lib per corner) on a DEF file, reporting per-corner WNS/TNS plus the worst corner.
- `openroad_toolchain_info` — Returns active container/host runtime and version information for OpenROAD, OpenSTA, and supported platform PDKs.
- `openroad_eval` — Evaluates a Tcl snippet in a fresh stateless OpenROAD session and returns capped stdout. Include any read_lef/read_liberty/read_def setup the query needs; no state persists between calls.

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
