1Claw Vault vs Pentagonal
A side-by-side look at the 1Claw Vault and Pentagonal MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose 1Claw Vault for security work as a local process; choose Pentagonal 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 1Claw Vault 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:
ONECLAW_AGENT_API_KEY, ONECLAW_AGENT_TOKEN, ONECLAW_VAULT_ID, ONECLAW_LOCAL_ONLY, ONECLAW_LOCAL_VAULT, ONECLAW_DAEMON_SOCKET, MCP_TRANSPORT, PORT. - You want tools like
list_secrets, get_secret, put_secret.
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.

Tools & capabilities
1Claw Vault tools 37
list_secretsList all secrets (metadata only — never values)get_secretFetch the decrypted value of a secret by path. Accepts optional `client_share` for MPC vaults.put_secretCreate or update a secret (creates a new version). Response includes `client_share` when the vault has MPC enabled.delete_secretSoft-delete a secret at a pathdescribe_secretGet metadata without fetching the valuerotate_and_storeStore a new value for an existing secret and return the versionrotate_generateServer-side secret rotation with generated value (length, charset configurable)list_versionsList all versions of a secret (version numbers, dates, disabled status)get_env_bundleFetch an env_bundle secret and parse it as KEY=VALUE JSONlist_child_agentsChild agents under a parent (own key/memory/policy, subset of the parent's access; vault ≥ 0.61.30)resolve_envResolve environment variables for a vault and environment (returns the final KEY=VALUE set with precedence applied). When the agent has `env_auto_resolve: true`, omit `environment` and the server uses the agent's tagged environment from the JWT.create_vaultCreate a new vault (auto-shared with the agent's human creator)- +25 more on the listing page
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.

Frequently asked questions
1Claw Vault is categorized under Security and uses a local stdio subprocess. Pentagonal belongs to Security and uses a local stdio subprocess. Pick 1Claw Vault for security work and Pentagonal 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.
1Claw Vault has no declared pricing — check the project's own site. Auth: api key required. Pentagonal is listed as freemium — a free tier with paid plans. Auth: api key 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 1claw-vault and pentagonal-ai-pentagonal as separate keys in the same mcpServers object, and your assistant will call tools from either one.
