What is the Pentagonal MCP server?

Pentagonal MCP server exists for a simple reason — assistants are far more useful when they can act on Pentagonal directly instead of describing what you should do. AI smart contract forge — 8-agent security audits, generation, and compilation across 8 chains.

What you get

AI-powered smart contract forge with an 8-agent adversarial security audit system.

What the assistant can call

Once Pentagonal is connected, these are the calls the assistant has available:

  • pentagonal_lookup — Token intelligence — price, holders, LP lock, honeypot, source code
  • pentagonal_audit — 8-agent security pen test with severity grouping and PoC exploits
  • pentagonal_generate — Generate contracts from natural language (Solidity + Anchor/Rust)
  • pentagonal_fix — Fix a specific vulnerability while preserving functionality
  • pentagonal_compile — Compile Solidity to ABI + bytecode + gas estimates
  • pentagonal_rules — View accumulated self-learning security rules
  • pentagonal_chains — List all supported blockchains

Configuration and credentials

You will need one environment variable: PENTAGONAL_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Setting it up

pentagonal-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Choosing this one

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Pentagonal's toolset — pentagonal_lookup, pentagonal_audit, pentagonal_generate and 4 more — is a fair guide to whether it matches your workflow. It is maintained by Achilles1089; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the pentagonal mcp server does with a few real requests.

Frequently asked questions

It connects Pentagonal to MCP-compatible AI assistants such as Claude and Cursor, exposing 7 tools (pentagonal_lookup, pentagonal_audit, pentagonal_generate, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Pentagonal directly.
