"Projects that showcase advanced GitHub repository search techniques" matching MCP connectors:

Search scored onchain agent frameworks, MCPs, wallets, tools, and live agents.

Search and license 5,000+ fully cleared music tracks via MCP. AI agents can find music by genre, mood, BPM, and instrumentation, then license instantly with USDC on Base. No human in the loop. Also includes free music industry knowledge tools: platform loudness standards, royalty calculators, and genre conventions.

Free, keyless MCP server with 50 read-only blockchain tools for Bitcoin, Ethereum, and Mezo. No installation, no API key required -- just add the URL to your MCP client and start querying balances, transactions, blocks, ENS names, ERC-20 tokens, smart contracts, and more. Runs on Cloudflare's global edge network via Streamable HTTP. All tools are strictly read-only and stateless.

Crypto positioning and macro intelligence for agents — the signal set a trading desk watches, delivered as structured JSON. Multi-venue perpetual funding and open interest across Binance, Bybit and OKX (largest-open-interest perp per venue, thin venues excluded), Ethereum exchange whale flows, Bitcoin network health, DeFi TVL and stablecoin supply, Fear & Greed, and BTC/ETH/USDT dominance as a risk-on/risk-off regime filter. Plus the macro backdrop that actually drives crypto: Fed funds rate, 2Y

Blockchain SSN for AI agents. MCP gateway that blocks at the point of action, tamper evident audit.

Deploy and manage blockchain nodes across 70+ protocols, search docs, request testnet funds.

Search, read & publish paid essays. Pay-per-read in USDC on Base (x402); wallet-only, no account.

44 MCP tools to search, value, register, trade, and manage ENS names. AI-powered intelligence layer.

x402-paid tools: EU company & sanctions data, web search, LLM chat, crypto intel, x402 monitoring.

Real-time DEX and on-chain data across 36 blockchains: liquidity pools, token prices, OHLCV, transactions, and cross-chain search. 17 keyless tools.

x402 paid APIs for AI agents on Base. Blockchain, wallet, DEX, crypto, web search.

Celestia knowledge base: CIPs, docs, forum, videos, GitHub, plus live on-chain state

Doc search, intent & cross-chain swaps, limit orders, portfolio, spot prices, gas & all APIs.

JPYC (JPY stablecoin) EC platform MCP: product search, x402 gasless checkout, order status.

Bitcoin-anchored sealed-forecast record: search, grades, calibration, luck test. Read-only, no key.

Agent-native scoring, search and routing for tokenized real-world assets across multi-chain.

PQC scanner for GitHub repos and smart contracts. Detects quantum-vulnerable ECDSA/RSA.

Post-quantum cryptography (PQC) vulnerability scanner. Detects ECDSA, RSA, AES-128 and other quantum-vulnerable algorithms in GitHub/GitLab/Bitbucket repos and Ethereum smart contracts. Returns risk score 0-100, CBOM (CycloneDX 1.6), and migration paths to NIST FIPS 203/204/205. Free tier: 10 scans/day, no key required.

An identity and memory layer for AI agents on the Emercoin blockchain. An agent claims a GitHub-rooted on-chain identity and stores verifiable hashes of its research and memory as Emercoin NVS (Name-Value Storage) records, through a small authenticated HTTP API and an MCP server. Neutral and provider-independent — not tied to any single AI vendor. FREE

Verifiable document intelligence for AI agents. Extract, summarize, claim-check, and notarize PDFs & URLs with cryptographic proofs, cross-document search, and on-chain attestation via Base L2.
