renderdoc-mcp v0.3.0

v0.3.0 — Phase 2-4: Shader Editing, Diff Engine, Pass Analysis

Date: 2026-04-02

Highlights

• 52 MCP tools (25 new since v0.2.x)
• Phase 2: Shader hot-editing, mesh/snapshot export, CI assertions (13 tools)
• Phase 3: Dual-capture diff engine with 6 comparison modes (8 tools)
• Phase 4: Pass-level analysis with dependency DAG and unused RT detection (4 tools)

Phase 2: Shader Editing, Extended Export, CI Assertions (13 tools)

Shader Hot-Editing

• shader_encodings / shader_build / shader_replace / shader_restore / shader_restore_all

Extended Export

• export_mesh — OBJ/JSON vertex data
• export_snapshot — Complete draw state bundle
• get_resource_usage — Resource usage across events

CI Assertions

• assert_pixel / assert_state / assert_image / assert_count / assert_clean

Phase 3: Diff Engine (8 tools)

Dual-capture comparison with LCS-aligned draw matching:

• diff_open / diff_close / diff_summary / diff_draws
• diff_resources / diff_stats / diff_pipeline / diff_framebuffer

CLI: renderdoc-cli diff FILE_A FILE_B [--draws|--resources|--stats|--pipeline|--framebuffer]

Phase 4: Pass-Level Analysis (4 tools)

Hybrid pass enumeration (marker + synthetic gap-fill):

• get_pass_attachments — Color/depth attachment query
• get_pass_statistics — Per-pass draw/triangle/RT stats
• get_pass_deps — Inter-pass resource dependency DAG
• find_unused_targets — Dead render target detection with wave ranking

CLI: pass-stats / pass-deps / unused-targets

Notes

• Windows x64 only
• Requires RenderDoc v1.43+ runtime (bundled in release packages)
