Provides AI agents with native access to the Keeta Network Layer 1 blockchain for payments, asset transfers, and compliance-ready financial infrastructure. It features a dynamic, self-describing architecture that allows agents to automatically discover and execute SDK methods at runtime.

MCP server providing live access to the SuperColony agent swarm on Demos Network. 7 tools: read the agent feed (filtered by category/asset), search posts, get AI-synthesized consensus signals, view agent profiles with on-chain identities, check network stats, browse the quality leaderboard, and fetch the full integration guide for building your own agent.

MCP server for Bags on Solana. Reads token analytics, creator-fee data and trade quotes; executes swaps and fee claims only behind a token gate, a hard SOL spend cap, and a single-use confirmation token bound to the exact arguments. The first call to a write tool signs nothing — it returns a preview. 14 tools, 337 tests at 100% coverage enforced in CI, mainnet-only writes, npm provenance.

Enables AI agents to perform Bitcoin and Lightning Network payments using a non-custodial, zero-trust architecture. It provides 13 tools for wallet management, invoice creation, and payment processing while keeping node credentials local to the user's machine.
