Cli Market

LATAM price intelligence for AI agents — 41 verified retailers across 8 countries (PE, AR, BR, MX, CO, CL, IT, FR). 61,000+ prices refreshed every 4h. Tools for search, compare, basket optimization, inflation signals, and procurement workflows. Free API key at cli-market.dev.

Conduit

Conduit is a local-first gateway that puts every MCP server behind one endpoint shared by all your AI coding tools (Claude, Cursor, VS Code, Codex, and more). Set up and authenticate each server once, then connect every client to Conduit instead of re-adding servers everywhere. Keys stay in your OS keychain (never in client configs), lazy discovery exposes just 3 meta-tools so your agent's context stays small no matter how many servers you add, and you can toggle servers on/off live without restarting the client. Proxies both local (stdio) and remote (http/SSE) servers, with a built-in audit log and tool playground. No Docker, no cloud, no account. Free and open source (MIT). Windows, macOS, and Linux.

B

Brazilian Sanctions

An MCP (Model Context Protocol) server that provides access to Brazilian sanctions databases through the Porta da Transparência API.

Elsas Security Intelligence

Daily, Ed25519-signed security intelligence for AI-agent stacks: CVEs, supply-chain incidents and advisories (GHSA/CISA-KEV/OSV/NVD + national-CERT) assessed for MCP/LLM-proxy impact, cross-validated and signed. Paid via x402 ($0.10 USDC on Base); free sample, list_available, check_affected, get_since.

N

Nes Coherence Signal

NES (Net Entropy Score) measures brand coherence: how consistent a brand's public story is, and how far that claim sits from what's actually happening. Connect this MCP server to Claude, ChatGPT, or any MCP client, then ask in plain language ("using NES, tell me about Stripe"). You get the brand consistency score (the claim), recent news (the reality), and the divergence between them. Directional read from public signal, not a fraud or financial check. Free.

ADSUMO - #1 MCP for ad creatives

Adsumo turns any MCP-compatible AI tool into an ad studio. Connect once and your assistant can create professional, on-brand image and video ads without design tools or manual exports. Onboard a brand from a URL and Adsumo learns its logo, colors, voice, and products, so every ad comes out on-brand automatically. From there you can generate batches of image ads, produce video ads with Sora, Veo, Kling, or Seedance, edit and reframe creatives for any placement, translate copy into 100+ languages, and research what is winning in your niche through the built-in ad library. Run a single prompt or fire a full launch campaign across formats in one chat. *Some features require a subscription

OMNFLOW

Omnflow MCP gives AI agents three content automation tools: repurpose_content turns a blog post, transcript, or idea into 5 platform-ready posts (Twitter, LinkedIn, Instagram, etc.), analyze_voice extracts a writer's Voice DNA — tone, sentence style, and patterns — from any writing sample, and list_recent_demos lists recent public demo runs so you can see real inputs and outputs. Connect via https://omnflow.com/api/mcp.

OpenSEO

SEO research tools for AI agents: keyword research and metrics, SERP and local SERP results, domain and backlink analysis, rank tracking, and Google Search Console performance.

BUILDY

Buildy lets ChatGPT, Claude, or any coding agent build real web apps on demand. The app works across agents, so you can build it once and keep using the same app/data from ChatGPT, Claude, Codex, or wherever your agent runs.
