"Deutsche Post" matching MCP servers:

Provides a self-serve recipe for agents to anonymously post and read blames on blame.today via Nostr.

MCP server for Hive Origin that stamps work hashes with dual-signed post-quantum receipt envelopes (ML-DSA-65 + Ed25519) for copyright creation proof, plus queries for proven creators and paginated work history.

Enables Claude Desktop, Claude Code, and Claude.ai to interact with a Buzz relay, allowing users to list channels, read/search messages, and post chat events using NIP-98 authentication.

Run a Shopstr / NOSTR marketplace storefront from an AI agent — create and update stalls and products in both the NIP-15 dialect and the Shopstr-modern NIP-99 dialect, including the cache POST that makes Shopstr cards actually render.

Enables AI agents to create and post signal coins on the Base blockchain through tools for media uploads, transaction generation, and on-chain submission. It supports both fully headless automated execution and manual signing modes using the x402 payment protocol.

A wallet for AI agents: test funds, payments, paid APIs and escrow on Aether. Give an AI agent its own wallet on Aether, a proof-of-work chain with post-quantum (ML-DSA-44) signatures. The agent gets an address and testnet funds in one step, then sends and receives AETH or USDC under per-payment and daily limits you set. It can pay for APIs that answer HTTP 402, sell its own, rate the services it

Enables comprehensive Stacks blockchain development with 30+ specialized tools for Clarity smart contracts, SIP compliance, security analysis, and performance optimization. Provides complete access to SIP standards, token development templates, security-first patterns with mandatory post-conditions, and full-stack dApp development guidance.

Enables natural language queries and JSON-RPC calls to 69+ blockchain networks through Grove's free public endpoints. Supports Ethereum, Solana, Cosmos chains, and Layer 2 solutions without requiring authentication or API keys.

Enables Claude, Cursor, and other MCP clients to connect by pasting a single Streamable HTTP URL and invoke public tools for stack description, Robinhood Chain ping, BLAKE3 hashing, transaction verification, post-quantum crypto, registry, and product API health, plus user-paid on-chain writes. Cryptographic operations and chain-id-guarded settlement on Robinhood Chain testnet 46630 are delegated to the SDK, requiring a product API key and the caller's own funded wallet for writes.

Read-only chain data, AI inference, verifiable quantum randomness, and mining stats for the Animica post-quantum L1 — 15 tools, no private keys.

Enables agents to read a pseudonymous message network's public feed, claims ledger, marketplace listings, and signed Merkle ledger chain, and — with a paid or proof-of-work pass — to post, claim, and trade capabilities with other agents. Every entry is chained into signed Merkle roots so clients can verify the record themselves with a standalone verifier instead of trusting the server.

Enables AI agents to access 48 real-time crypto data tools including prices, DeFi, meme tokens, gas, sentiment, Solana, and agent commerce, with post-paid billing via Solana USDC.
