An MCP server with GitHub OAuth for remote connections, providing tools for arithmetic, GitHub user info, and image generation.

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

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.

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.

Enables AI agents to search, filter, and monitor curated AI model API free credits and low-cost token promotions through eight tools, four resources, and three prompts — including finding deals expiring soon, checking eligibility and blocked conditions, and producing daily briefs.

A production-ready MCP server with OAuth 2.1 and PKCE for secure third-party API access, featuring GitHub user info retrieval and LLM-powered code analysis.

A Node.js MCP server with custom OAuth 2.1 + PKCE authentication, enabling secure remote connections to LLMs like Claude and ChatGPT.

End-to-end Prior Authorization decision-support system with a multi-agent AI pipeline, MCP Tool Registry, and PostgreSQL backend.

MCP server for step-by-step mathematical reasoning and planning, enabling AI agents to execute calculations and perform GUI actions like opening PowerPoint.

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

MCP server for MarkItUp's AI image-annotation pipeline. Generate polished marketing-visual variations of any screenshot, regenerate, AI outpaint, and remove backgrounds — powered by Claude analysis + Gemini rendering.

Discover audio and LLM services, compare seven voices, and check prices for free. Generate speech, transcribe audio and request LLM text with optional capped USDC payments on Base; voice-cloning requirements are also available.

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.

Enables users to run synthetic support-agent evaluations, preserve and inspect traces, score results deterministically, inject failures, and enforce release review gates through MCP tools, resources, and prompts.

AI payment router for routing across 300+ LLM models with per-request USDC settlement on Base and Tempo, session budgets, and x402 payments via the MCP protocol.

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.
