"OpenTimestamps - Bitcoin-based timestamping protocol" matching MCP servers:

Provides live Bitcoin network data (fees, mempool, hashrate) and AI-powered price/fee forecasts via MCP tools, with free access to basic data and pay-per-call for advanced features.

Trust, identity, and reputation infrastructure for AI agents. Register agents with W3C DID (Ed25519), check EigenTrust reputation scores, submit peer attestations, search agents by capability, and verify IPFS-anchored audit trails. 11 tools.

Provides current weather information for any location and generates AI-powered responses using Google Gemini through FastMCP.

A production-ready MCP server template that connects LLMs and AI agents to external data, tools, and services with built-in OAuth 2.1 authentication, Redis-backed session management, and a modular tools engine.

A lightweight, zero-dependency MCP gateway adapter that enables Claude/Cursor agents to process structured JSON payloads and integrate with GenPark AI agent pipelines.

Look up AI agents' evidence-based reputation and record two-party signed work receipts (INAM Protocol). Tools for agent search, reputation checks, job posting, receipt drafting/countersigning, and content hashing, against a registry with operator-authorized verification and a Merkle transparency log.

Security middleware for LLM apps and AI agent pipelines. Detects prompt injection attacks (22 signatures, 7 languages) and anonymizes PII (17 entity types). Deterministic, sub-25ms, GDPR Art.30 compliant.

Enables agent harnesses to make fast, confidence-aware tool selections using Jev, with planner fallback, hierarchical routing, and optional MCTS lookahead, exposed natively over MCP stdio.

Agentic AI instruction encoding. 86.8% smaller than JSON. Inference-free decode by table lookup. 342 opcodes, 26 namespaces, three conformant SDKs. Confirmed over LoRa mesh radio. Apache 2.0 with express patent grant.

MCP-compatible proxy hub that intelligently filters tool responses to stay within LLM context window budgets. SCP sits between your LLM client and MCP servers, treating context as a budget, not a dump. Every token must earn its place through measured relevance. Clients connect to SCP as if it's a normal MCP server — zero changes required.

Self-evolving AI Agent framework — search, compare, and install Genes ranked by Arena fitness via MCP

Enables interactive AI chat through the Anthropic API, with document retrieval, slash commands, and extensible MCP tool integrations.

An MCP server that gives AI citizens access to a shared knowledge graph governed by 21 physics laws.

Enables AI agents to manage personal expenses via natural language through add, query, summarize, and delete expense tools.

Let any MCP client issue and verify EU AI Act Article 50 transparency receipts for AI-generated content, anchored to Bitcoin.

Enables multi-level reasoning with configurable depth levels, session-based state management, structured thought input, and real-time trace resources.

MCP server for key driver and feature importance analysis based on rule mining

A transparent, user-owned model router and orchestration control plane that enables AI workflow orchestration via an MCP server, with supervisor-based task decomposition and cross-provider routing.

Enables Claude Code to use GLM (Zhipu) as a cheap, full-capability subagent for file editing, code generation, and bash commands, with automatic routing between Opus and GLM based on task complexity.

A calibrated faithfulness screen for informal↔Lean 4 statement pairs, served over MCP. It provides deterministic checks and deep LLM-based analysis to help draft Lean statements.
