WaxSeal MCP gives AI agents cryptographic identity — verify any WaxSeal fingerprint, check Ed25519 signatures, and gate irreversible actions with human-signed approval tokens before execution. It connects Claude Desktop, Cursor, and Windsurf to the WaxSeal trust network so agents can prove who authorized an action and reject tampered credentials in under a second.

Enables Claude to turn a described beat into a loopclub deep link for auditioning and renting on-chain by encoding track specs into a ?jam= URL and returning an ASCII grid. It also supplies vocabulary, genre examples, and a jam prompt to help generate idiomatic loops.

Enables AI agents to retrieve real-time data on wallet DeFi positions, token balances, and NFT holdings across multiple blockchains. It supports hundreds of protocols and provides specialized tools for chain-specific or protocol-specific portfolio analysis.

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.

An MCP server that provides access to Stern, a philosophical AI mentor combining rationalist thinking with stoic philosophy to guide users through personalized mentorship and smart contract accountability on Solana.

Enables to simulate EVM transactions (dry-run) to preview results, gas usage, and state changes before broadcasting on supported blockchains.

MCP server for witnessd, enabling agents to create tamper-evident, signed, and Merkle-anchored certificates of any public URL or API response at a moment in time.

Enables remote MCP servers to request wallet approvals, signatures, and transactions through an approval URL while keeping private keys in the user's browser wallet.

Enables any MCP host to search job postings on hashtagweb3.com by keyword, location, remote preference, and posting date, and to fetch full details for a specific listing. It exposes the board's public API/RSS as the read-only, rate-limited tools search_jobs and get_job.

Enables agents and users to query the Telegraph network through a hosted MCP endpoint, with tools to ask miners, request specific miners, retrieve intents/recipes, and verify signal hashes on-chain.

OTrust issues cryptographic PDRs (Provenance Data Records) — proving a digital artifact existed at a specific time. $0.01 per proof. Blockchain-anchored. Publicly verifiable.

A production-ready Model Context Protocol server implementation that connects AI assistants to the TON blockchain, allowing them to query wallet balances, transaction details, smart contracts, and other blockchain data.

A Model Context Protocol server that enables natural language interaction with the TON blockchain, allowing users to perform queries for balances, analyze trading patterns, detect hot trends, and conduct forensic investigations on blockchain data.

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

Automated risk triage, liquidity checks, and security guardrails for AI agents operating on the AO / Arweave network.

A comprehensive MCP server providing unified access to over 144 tools for lending, trading, and staking across six major DeFi protocols on the Stacks Bitcoin Layer 2. It enables AI agents to perform complex blockchain operations and interact with the DeFi ecosystem using natural language commands.

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.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Enables LLMs to interact with the AT Protocol ecosystem, including Bluesky, through natural language. Supports public data access without authentication and full write operations with authentication.
