Pentagonal vs Binary Ninja MCP
A side-by-side look at the Pentagonal and Binary Ninja MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Pentagonal for security work as a local process; choose Binary Ninja MCP for security as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Pentagonal when
- You need dedicated capabilities in the Security domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
PENTAGONAL_KEY. - You want tools like
pentagonal_generate, pentagonal_lookup, pentagonal_audit.
Choose Binary Ninja MCP when
- You need dedicated capabilities in the Security domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
- You want tools like
list_methods, get_entry_points, search_functions_by_name.

Tools & capabilities
Pentagonal tools 7
pentagonal_generateGenerate a production-quality smart contract from a natural language description. Supports EVM (Solidity) and Solana (Anchor/Rust or SPL Token config). The generator uses Pentagonal's self-learning security rules to produce safer code.pentagonal_lookupLook up any token or smart contract by address. Returns the full intelligence report: price, market cap, ATH, 24h volume, transactions, holders, liquidity, LP lock status, pool count, security flags (honeypot, mintable, pausable, hidden owner, taxes), social links, and source code if verified. Use this before auditing to understand the full token landscape. Supports EVM and Solana tokens. Chain is auto-detected if omitted.pentagonal_auditRun an 8-agent security pen test on a smart contract. Each agent specializes in a different attack vector: reentrancy, flash loans, access control, gas griefing, oracle manipulation, front-running, integer overflow, and economic exploits. Findings are returned with severity ratings and line numbers. New security rules are automatically learned from each audit.pentagonal_fixFix a specific vulnerability in a smart contract. Provide the contract code and the finding details — returns the complete fixed contract preserving all existing functionality.pentagonal_compileCompile Solidity source code and return the ABI, bytecode, constructor arguments, and gas estimates. Use this after generating and auditing a contract to prepare it for deployment.pentagonal_rulesGet the current self-learning security rules. These rules are accumulated from every audit Pentagonal performs — the more contracts audited, the smarter the system gets.pentagonal_chainsList all supported blockchains with their chain IDs, explorer URLs, and deployment hints.

list_methodsList all function names in the program with pagination.get_entry_pointsList entry point(s) of the loaded binary.search_functions_by_nameSearch for functions whose name contains the given substring.decompile_functionDecompile a specific function by name and return the decompiled C code.get_ilGet IL for a function in the selected view (hlil, mlil, llil).fetch_disassemblyRetrieve the disassembled code of a function as assembly mnemonic instructions.rename_functionRename a function by its current name. The configured prefix will be automatically prepended if not present.rename_single_variableRename a variable in a function.rename_multi_variablesRename multiple local variables in one call.rename_dataRename a data label at the specified address.set_commentSet a comment at a specific address.get_commentGet the comment at a specific address.- +42 more on the listing page

Frequently asked questions
Pentagonal is categorized under Security and uses a local stdio subprocess. Binary Ninja MCP belongs to Security and uses a local stdio subprocess. Pick Pentagonal for security work and Binary Ninja MCP for security.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Pentagonal is listed as freemium — a free tier with paid plans. Auth: api key required. Binary Ninja MCP is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add pentagonal-ai-pentagonal and fosdickio-binary-ninja-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
