Pyslang Mcp
Let your coding agent analyze Verilog and SystemVerilog trees with compiler-grade accuracy instead of guessing from raw text.
Overview
pyslang-mcp is a Build-phase MCP server that gives coding agents compiler-backed, read-only Verilog and SystemVerilog project analysis through the Model Context Protocol.
What is this MCP server?
- Compiler-backed read-only analysis of Verilog and SystemVerilog projects via pyslang
- stdio MCP transport with PyPI package pyslang-mcp (runtimeHint uvx)
- Version 0.1.0a3 alpha—suitable for exploration before production RTL flows
- No write or synthesis path—safe static introspection for agents reviewing RTL
- GitHub repository ariklapid/pyslang-mcp with MCP registry schema 2025-12-11
- Registry version 0.1.0a3 on PyPI identifier pyslang-mcp
- Single stdio transport package in server manifest
- GitHub repository id 1214106457 (ariklapid/pyslang-mcp)
What problem does it solve?
Agents skim RTL as plain text and miss syntax-scoped structure that only a real SystemVerilog compiler front end can expose.
Who is it for?
Indie hardware hackers and small teams who want LLM-assisted RTL review and project navigation without granting write access to the design.
Skip if: Teams that need synthesis, formal verification runners, or non-HDL application development with no Verilog footprint.
What do I get? / Deliverables
After you register pyslang-mcp, your agent can query project-aware HDL context from stdio MCP tools grounded in pyslang instead of hallucinated module lists.
- Registered stdio MCP server entry for compiler-backed HDL analysis
- Agent-callable read-only views of Verilog/SystemVerilog project structure
- Grounded RTL context for review and documentation prompts
Recommended MCP Servers
Journey fit
Hardware and FPGA work sits in the build phase when you integrate design files into an agent-assisted workflow. Read-only MCP tools wire the slangs compiler into the agent stack as a project-analysis integration, not a ship-time gate.
How it compares
Compiler-integrated MCP bridge for HDL, not a generic code-search skill or cloud EDA SaaS.
Common Questions / FAQ
Who is Pyslang Mcp for?
It is for solo builders and small hardware teams who use AI coding agents on Verilog or SystemVerilog repos and want analysis aligned with a real compiler front end.
When should I use Pyslang Mcp?
Use it during build and integration work when you need read-only project structure, module awareness, or agent-driven RTL review before tape-out or CI lint stages.
How do I add Pyslang Mcp to my agent?
Add the MCP server entry pointing at uvx/Pyslang Mcp with stdio transport per the registry package on PyPI, then restart Claude Code or your MCP-capable editor.
