"crypto" matching MCP servers:

Enables cryptographic operations including hashing, encoding/decoding, ID generation, password tools, and JWT inspection via MCP.

Enables checking whether a crypto link is a phishing lookalike of a wallet, exchange or dapp by comparing it against official domains and flagging lookalike characters, typosquats, punycode and bait words, fully offline. An optional paid full check adds domain registration age, DNS, redirect tracing and a page scan for seed-phrase prompts and drainer code.

Defense-grade cryptographic compliance and analysis tools for MCP, including FIPS 140-3 validation, CNSA 2.0 analysis, post-quantum readiness assessment, and classical cipher utilities.

Enables secure validation of agent credentials through constant-time digest comparison, JWT HMAC-SHA256 checks, Merkle inclusion proofs, Schnorr zero-knowledge verification, and nonce replay protection. It integrates natively with MCP clients to harden autonomous agent authentication workflows.

Enables constant-time cryptographic attestation, zero-knowledge verification, JWT HMAC-SHA256 validation, Merkle proof inclusion, nonce replay protection, and secure digest comparison for agent security credentials via MCP.

Read-only safety checks before an agent acts: scan untrusted text for prompt injection and phishing (locally), check npm packages for malware, hijacked releases and typosquats, scan crypto addresses and tokens, and compare two addresses to catch address poisoning. Zero dependencies.

Generates strong passwords and evaluates password strength using zxcvbn, with uniform random sampling via Node's crypto.

Exposes various cryptographic operations including key generation, symmetric/asymmetric encryption, hashing, and HMAC. Supports Fernet, AES, RSA, X.25519, and X.509 certificates.

Enables AI assistants to check whether a crypto token, link, or forwarded "gem" message is a scam by running contract rules, live test trades, creator history, and market data across 64 networks, returning plain-English or Pidgin verdicts. Also supports scanning messages, reviewing a token's past checks, and explaining individual findings.

Enables users and AI agents to verify whether a crypto recipient address is an address-poisoning lookalike or has an invalid EIP-55 checksum before sending funds, and provides access to an on-chain history scan for suspicious transfers.

19 tools for crypto token risk intelligence. Detect rug pulls, honeypots, and scams before your agent transacts. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.

Provides blockchain address risk scoring and asset information through the BICScan API, allowing users to assess risks for crypto addresses, domains, and dApps on a scale of 0-100.

Enables agents and developers to generate and verify Poseidon Merkle membership proofs, verify Groth16 zk-SNARK proofs, construct and verify Merkle Mountain Range proofs, create SHA-256 Merkle inclusion proofs, and hash EIP-712 typed structured data for private identity and Web3 workflows.

A Model Context Protocol server for AES encryption and decryption, supporting various modes, padding, and input/output formats for secure data handling.

Enables agents to generate tamper-evident SHA-256 Merkle audit trails, produce logarithmic inclusion proofs, and verify integrity through a STDIO MCP interface.

Enables AI agents to call 50+ pay-per-request tools covering onchain and crypto data, web research, security, compliance screening, business intelligence, and infrastructure checks. Payments settle per call in USDC on Base through the x402 protocol with no accounts, API keys, or subscriptions, and the first call is free for new wallets.

Enables agents to inventory cryptographic primitives and score their quantum break cost, rupture year, and harvest-now-decrypt-later exposure against modelled attacker roadmaps and compliance deadlines. Exposes read and idempotent mutation tools for saving assets, sequencing migration waves, freezing verifiable partner reports, and replaying a SHA-384 audit chain to confirm integrity.

This MCP server enables real-time injection fuzzing, exfiltration canary detection, least-privilege tool sandboxing, and cryptographic Merkle audit proofs for agent prompts, RAG context, and actions. It provides tamper-evident SHA-256 tree generation, logarithmic inclusion proofs, and verifiable integrity checks through MCP.

Exposes common CTF and cybersecurity tools (crypto, forensics, malware analysis, steganography, reverse engineering, pwn, OSINT) so LLMs can help solve capture-the-flag challenges in a controlled lab environment.

Enables MCP clients to read and safely modify an HPE Aruba EdgeConnect SD-WAN Orchestrator through its REST API, using plain-language requests that are translated into the correct operations. Writes are opt-in and confirmed, secrets are redacted before reaching the assistant, and every call is audited.
