"An overview of knowledge graphs and their applications" matching MCP servers:

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

Exposes nine purpose-built tools for EVE: Frontier on Sui Move, covering Smart Assembly contract coding, Smart Gate route and toll planning, Network Node gigajoule optimization, Smart Turret targeting, killmail threat intel, SSU market making, zkLogin character verification, sovereignty fuel tracking, and PTB drain simulation.

An MCP server for Klever blockchain smart contract development, providing contextual knowledge including code patterns, best practices, and runtime behavior.

Cross-chain DeFi intelligence MCP server for AI agents. 7 tools for yield discovery, pool analysis, profit simulation, risk scoring, whale tracking, impermanent loss calculation, and DeFi overview across 86 chains and 6,500+ liquidity pools.

An MCP server that exposes the satring.com L402 service directory, enabling AI agents to search and query Lightning-paywalled and stablecoin-gated APIs without needing prior knowledge of their URLs.

Algorand ecosystem knowledge layer as an MCP server, enabling identification of applications and assets, protocol discovery, name resolution, and protocol summaries without on-chain queries.

Provides tools for AI agents to access Bitcoin, Lightning Network, and Nostr knowledge, including real-time network statistics and Web of Trust reputation data. It features an integrated Lightning Network payment system for micro-transactions and query-based interactions.

A Model Context Protocol server that allows AI assistants and applications to access IQ.wiki data, enabling retrieval of specific wikis, user-created wikis, user-edited wikis, and detailed wiki activities.

Enables users to audit EVM, Solana, and Move smart contracts and assess Web3 security risks through tools for honeypot detection, SPL token risk, MEV sandwich exposure, address poisoning, HTTP 402 invoice fraud, UTXO consolidation planning, and cross-chain bridge quotes.

Provides AI agents with knowledge and code generation tools for building BSV blockchain applications using @bsv/simple.

Enables an AI agent to search a curator-signed catalog of smart contracts, build transaction plans with per-call trust tiers, and simulate them before a human reviews and signs locally with their own wallet. The server never holds a private key, refusing only calls whose deployed code no longer matches the signed codehash.

Enables autonomous agents to emit zero-knowledge attestations of their internal state hash and DID, anchor commitments to Base, and verify proofs via Aleo snarkVM.

MCP server that enables AI agents to explore Bittensor subnets, check their health and economics, and discover their public APIs and schemas.

Connects MCP-compatible agents with the OriginTrail Decentralized Knowledge Graph, enabling creation, retrieval, linking, and exchange of verifiable knowledge using natural language and SPARQL queries.

Enables on-chain attestation of any content onto the DigiByte blockchain, providing permanent, timestamped, tamper-evident proofs. Allows AI agents to notarize their outputs or verify attestations using only the blockchain.

Enables AI assistants to automatically integrate Divvi referral tracking into JavaScript/TypeScript blockchain applications by guiding them through SDK installation, transaction modification, and implementation of referral submission following official best practices.

Enables AI applications to interact with the COTI blockchain for private token operations, including deployment and management of private ERC20 tokens and ERC721 NFTs using COTI's Multi-Party Computation (MPC) technology.

Enables AI agents to generate and persist a self-sovereign did:key identity, sign claims about their actions as Ed25519 attestations, verify those attestations offline without any registry or network access, and compute an auditable reputation score from a ledger of events. All four operations are exposed as MCP tools so an agent can manage its own identity and prove its history during a session.

Exposes 8 read-only Trust Vault tools over MCP (Streamable HTTP) for querying protocol overview, tokens, market rates, orders, platform stats, fees, and currencies. Enables on-chain reads and static config without wallet or signing.

Enables AI applications to retrieve on-chain context from EVM-compatible blockchains via the Model Context Protocol.
