MCP Servers

PieterPost MCP lets AI agents prepare, price, review, pay for, and send real letters and postcards through PieterPost.

Bring enterprise-grade stock market data to agents and LLMs

Amazon brand, seller, niche & buy-box intelligence — inside your own Claude or ChatGPT. Webotee AI Connect adds Webotee's Amazon operator, brand, niche and seller research dataset to the AI you already use. Ask a question in Claude or ChatGPT and it queries the Webotee dataset directly — a research connector for sellers, built on 2+ years of daily US (and UK) marketplace observations of the BSR top‑1M+.

Structured, part-aware 3D generation for AI agents. Generates named-part GLB assets with intact hierarchy, real joints, and browser-based editing sessions.

Deploy AI user personas to validate user journeys at scale. Find UX friction before real users do. Stunt Double deploys AI agents with realistic user personas to validate user journeys at scale. Create actors, run automated workflows and checklists against any web app, and surface friction points before real users encounter them. Integrates with Claude, Linear, GitHub, Vercel, Webhooks, and Slack.

MuninX MCP connects compatible AI clients to MuninX, a simple help desk for small teams. It lets authenticated users inspect tickets, create and update tickets, read and create ticket messages, search visible support history, and query ticket analytics through a remote Streamable HTTP MCP endpoint. Access follows the user’s MuninX tenant, role, and permissions.

AI infrastructure coordination intelligence. Read-only tools serve verified events, Coordination Connections, Sovereign Capability Profiles, and methodology with semantic anchor mappings. Open free tier plus a token-authenticated analyst tier.

Stop hallucinating numbers. An MCP server that runs every math expression through four independent numeric engines in parallel and returns all four results side by side — so when they disagree, you know the answer is numerically unreliable.

Remote MCP server for AI coding agents that need realistic synthetic test data. Agents can estimate usage, create loginless Polar checkout, claim an API key, detect schemas from SQL or JSON, list field types/templates, and generate JSON, CSV, or SQL test data.

MCP server for astrology and divination. Connect Claude, ChatGPT, or any MCP-compatible AI to real ephemeris calculations across Vedic and Western astrology, numerology, and tarot. Covers natal charts, 5-level Vimshottari Dasha, yoga and dosha detection, matchmaking with Rajju/Vedha vetoes, panchanga, KP system, Lal Kitab, and tarot spreads. 103 tools, OAuth 2.1. Free sandbox tier — 500 calls/month, no credit card.

Brieform is an AI-native form builder built conversation-first. Other form builders bolt an MCP server onto a dashboard designed for clicking. Brieform works the other way: connect once in your chat client's MCP settings, describe a form, get a live URL back, and read responses in the same thread. It ships 12 MCP tools covering the full form lifecycle: create, publish, update, theme, read responses, analytics. Compatible with Claude, ChatGPT, Cursor, Le Chat, Perplexity, VS Code + GitHub Copilot, and any MCP client. Free to start, no credit card required.

Agent-native search engine with live web research optimized for AI agents.

Real browser automation for AI agents. Uindow ships a local MCP server that drives a real, signed Chromium/Electron browser with genuine OS-level input (real cursor movement, real keystrokes, native file dialogs) entirely on the user's own machine. Any MCP-compatible assistant can list, create, run, and inspect web-automation agents — no glue code.

MU is an AI-autonomous goods brand. Any agent can open a store, generate a design from a prompt (or upload artwork), and create real, shippable products across 40+ kinds — tees, hoodies, mugs, posters, gi, plus zero-shipping digital goods. Start with mu_register + mu_verify (no key needed). 23 tools over Streamable HTTP at https://mcp.wearmu.com/mcp. Connect: claude mcp add --transport http mu https://mcp.wearmu.com/mcp

Persistent memory and shared context for AI coding tools. Two local MCP servers give every AI coding tool a shared, permanent memory of your project across sessions and tools.

Sendmux is an email inbox API and email API for AI agents. Use this MCP server to let authorised agents work with Sendmux mailboxes, inbound email, clean JSON parsing, webhooks, outbound sending, provider routing, logs, billing, and team controls. Agents can read mailbox messages, send email, manage domains and mailboxes, inspect usage, and build multi-tenant email workflows without raw IMAP/SMTP plumbing.

Taisly Agent is an MCP server, CLI, SDK, and agent skill for publishing short-form videos to TikTok, Instagram Reels, YouTube Shorts, X, and Facebook through Taisly. It helps AI agents and automation workflows validate connected social accounts, create video posts, and check publishing status with a Taisly API key.

Open-source MCP server with ~1,100 deterministic tools — web search, headless Chromium, PDFs, OCR, images, ~1,040 CPU utilities. Free to self-host or pay per call via x402 (USDC on Base).

Hosted MCP server that gives any AI agent clean, semantically-searchable Reddit (and X) data — read-only, no Reddit API.

Outcome-aligned AI workflow registry. Design and run AI workflows with verifiers that align an agent to measurable outcomes, with reliable image output.

AI-native customer onboarding: live projects, KPIs, tasks, and emails with Onboard MCP. Connect Onboard to Claude or any MCP-compatible AI client to seamlessly surface blocked tasks, draft customer emails, monitor KPIs, and take action—right from your AI workspace. Access 27+ purpose-bu ilt tools that cover every stage of the customer onboarding lifecycle, all from within your preferred AI assistant.

EU AI Act compliance in your editor. Classify risk, cite obligations, draft Article 50 disclosures.

Generate finished, on-brand designs — logos, social posts, app-store screenshots, comic panels, and visual-novel assets — from a prompt. A remote MCP server backed by 119 templates: free browse/recommend tools, metered generation, OAuth sign-in. Works in Claude Code, Cursor, and ChatGPT.

Intelligent repository context for AI coding assistants. Provides code search, symbol lookup, call graphs, and reference tracking via MCP. Uniquely designed to minimize prompt-cache costs in long sessions stash/recall/remember tools keep large content out of context until needed, and a token-budgeted repository summary avoids unbounded prompt bloat. Works with any MCP client (Claude, Codex, Cursor, opencode, etc..). Go, CGO, tree-sitter-backed.

Schedule and publish social media posts to 11+ platforms (X, Instagram, Facebook, TikTok, LinkedIn, YouTube, Threads, Pinterest, Bluesky, Telegram, Google Business Profile) from Claude, ChatGPT, or Cursor. Connect via the hosted OAuth URL (no key, nothing to self-host) or run it locally with npx and your PostFast API key.

Aidress is the coordination layer for autonomous AI agents. It gives agents a way to find, verify, and transact with unknown counterparts — without handing back to a human. Today, AI agents fail at cross-agent transactions because there is no shared infrastructure for the steps that happen before a transaction: who is this agent, can it do what I need, should I trust it, and how do I route value to it? Aidress provides those five layers.
