"An overview of temporal knowledge graphs" matching MCP servers:

Enables AI agents to perform complex crypto operations like cross-chain routing, contract decoding, portfolio management, and anti-rug security checks, returning unsigned transactions for safe signing by the agent.

MCP server that prepares Proof of Invention (POI) transaction requests for submission

Official read-only MCP server for Aperture Wallet. Twelve tools provide verified public product, supported-mainnet, security, release, app-screen, and Journal knowledge without wallet access.

Enables AI agents to query curated Cartesi developer resources, documentation, and repository metadata through the Model Context Protocol. Provides read-only knowledge access and host-side workflow guidance for building Cartesi blockchain applications via streamable HTTP.

An MCP server that provides authorization middleware for AI agents using private data, enabling consent management on Aleo and local private inference with persistent policy storage.

An AI-driven platform for analyzing Polymarket prediction markets using on-chain data, offering smart money tracking, sentiment analysis, and arbitrage detection via natural language queries.

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.

An MCP server serving as a structured knowledge base of crypto whitepapers for AI agents to access, analyze, and learn from.

An MCP server that connects Claude to BrianKnows' blockchain knowledge base, allowing users to search for blockchain/DeFi information and interact with a specialized agent across multiple knowledge bases.

MCP server for temporal state queries and cryptographic audit trails. Query historical entity state at any point in time, generate Merkle proofs of past state, and anchor contract snapshots for immutable provenance.

Provides a persistent memory layer for Stellar and Soroban projects, scanning repositories to create a knowledge graph of contracts, storage, and on-chain state. Exposes this memory to AI agents via MCP, enabling project overview, search, and context recovery.

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.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

Agent-Level Transaction Safety Oracle. Before an AI agent signs a blockchain transaction, it returns a SAFE/UNSAFE verdict with a SENTINEL Score (AAA-D) and risk flags. Pay-per-call $0.005 USDC via x402 on Base.

Lets an AI agent hire and pay a verified human: post real-world tasks (voice, observation, judgment) and pay in USDC via a non-custodial x402 auth-capture escrow on Base, budget frozen at deploy. Humans verify their X identity before submitting.

Enables AI assistants to access live mining data for 126+ proof-of-work networks and 770+ hardware models, including network difficulty, hashrate, solo-mining odds, cost of production, hardware profitability, and mining news.

Screens the counterparty of an x402 payment before an agent pays it. One tool, screen_payment, checks address sanity, dynamic-payTo swaps, transport safety and your spend policy, then returns allow / review / block with the reasons — advisory only, and by default it runs with no key, no account and no network call.

Signed, verifiable crypto index prices for 5,000+ assets from the Pulse Verity Index. Five read-only tools: current price, batch prices, asset catalogue, the recorded print nearest a timestamp, and offline ECDSA signature verification of any print._
