Pentagonal vs Agent Security Scanner MCP
A side-by-side look at the Pentagonal and Agent Security Scanner 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 Agent Security Scanner 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 Agent Security Scanner MCP when

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.
Agent Security Scanner MCP tools 23
scan_securityScan a file for security vulnerabilities. Use verbosity='minimal' for counts only (~50 tokens), 'compact' (default) for actionable info (~200 tokens), 'full' for complete metadata.fix_securityScan a file and return fixes. Use verbosity='minimal' for summary only, 'compact' (default) for fix list, 'full' for complete fixed file content.record_security_outcomeRecord aggregate remediation outcomes after reviewing scanner findings. Sends counts only; never sends code, findings, paths, or rule IDs.list_security_rulesList all available security fix templates and their descriptionscheck_packageCheck if a package name is legitimate or potentially hallucinated (AI-invented)scan_packagesScan code for package imports and check for hallucinated (AI-invented) packages. Use verbosity='minimal' for counts, 'compact' (default) for flagged packages, 'full' for all details.list_package_statsList statistics about loaded package lists for hallucination detectionscan_agent_promptScan a prompt for malicious intent. Returns BLOCK/WARN/LOG/ALLOW. Use verbosity='minimal' for action only, 'compact' (default) for findings, 'full' for audit details.scan_git_diffScan git diff for new security vulnerabilities. Only reports issues on changed lines. Use for PR reviews.scan_projectScan an entire directory for security vulnerabilities with .gitignore support and security grading. Use verbosity='minimal' for grade + counts, 'compact' (default) for top issues, 'full' for all details.scan_agent_actionPre-execution security check for agent actions (bash, file_write, file_read, http_request, file_delete, cron, process_spawn, git, docker). Returns ALLOW/WARN/BLOCK.scan_mcp_serverScan an MCP server's source code for security vulnerabilities: overly broad permissions, missing input validation, data exfiltration, insecure patterns. Returns grade (A-F) and recommendations.- +11 more on the listing page

Frequently asked questions
Pentagonal is categorized under Security and uses a local stdio subprocess. Agent Security Scanner MCP belongs to Security and uses a local stdio subprocess. Pick Pentagonal for security work and Agent Security Scanner 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. Agent Security Scanner MCP has no declared pricing — check the project's own site. 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 agent-security-scanner-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
