"A server for understanding and navigating codebases" matching MCP connectors:
GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
WHOIS, RDAP, DNS, IP / ASN / CIDR and Web3 name (ENS, Unstoppable, Handshake) lookups. No API key.
Verify claims, resolve FIGI identity, extract claims, and sign x402 delivery receipts over MCP.
VPN, proxy, Tor, hosting and CDN detection for any IP address, from the VPNDetection API.
Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Brand protection: monitor domains, trademarks and app stores. Triage matches and track takedowns.
Let your AI agent pay for APIs and data without handing it your money. In ChatGPT, Claude or Grok, the agent finds paid x402 APIs (with each seller's payout record from x402 Doctor) and asks to pay; you approve and sign each payment in your own wallet: MetaMask or Coinbase Wallet (USDC on Base), Phantom (USDC on Solana) or Xaman (RLUSD on the XRP Ledger). Fizzl checks every payment before you sign and every paid answer for hidden instructions. Fizzl never holds your keys. Free to start.
Technology intelligence feed for AI agents: tech stack, compliance, security.
Find lookalike domains of a brand's website and see which resolve and what they show.
Block an action a signed mandate does not permit: amount, payee, audience, currency, window, intent.
Runtime permission, approval, and audit layer for AI agent tool execution.
DNS and email security: check SPF, DKIM, DMARC, DNSSEC, DANE and build the records. 45 tools.
Prove end users to agents and apps: login-links, OIDC clients, and API keys over remote MCP
Honeypot probe data: IP reputation, scanners, CVE probing, TLS and SSH fingerprints.
Is it DNS? Audit a site or domain that isn't working: one call says if it resolves and why. No key.
Shared second brain for any AI with agent permissions
Encrypted memory, knowledge graph and provable history for AI agents. ENYAL is the trust infrastructure for autonomous AI: identity, encrypted memory, and BSV-anchored proofs. Archived records are Merkle-batched and anchored to a permanent cryptographic ledger, and any record's inclusion proof can be checked by anyone, with no account.
Free website privacy scanner for pre-consent cookies, trackers, consent, policy, and HTTPS/TLS.
Check dependencies for known CVEs with EPSS and CISA KEV context. Read-only; free API token.
External checks of TLS, HTTP headers, email domain, DNS and ports, with cause and fix
Causal guardrail: pass/caution/hold verdict on a causal claim before an agent acts.
