MCP server directory

MoySklad cloud ERP for Russian retail and wholesale: stock, products, orders, counterparties and profit/turnover/cash reports, plus document writes (supplies, shipments, invoices, returns) over the JSON API 1.2. 892 schema-driven methods reached through 8 generic meta-tools, kopecks converted to rubles, and a read/write/destructive safety gate that needs an explicit confirmation before a document is created and a second one before it is posted or deleted. PyPI (`uvx moysklad-mcp-ru`), one-click installer for Claude Desktop, Claude Code, Codex and OpenCode. Alpha.

Turn markdown into a shareable link that renders as a typeset document (tables, Mermaid, math, pagination); the content lives in the URL, nothing is uploaded.

Reliability + security proxy that sits in front of MCP servers: TOFU tool-definition pinning against rug pulls, tool-poisoning and cross-server-exfiltration detection, argument/command-injection blocking, inline secret redaction, MCP 2026-07-28 header/body validation (`-32020`) and cache-policy clamping, and a compliance-mapped audit trail (NIST AI RMF / OWASP). Coverage measured on an open benchmark with a held-out corpus. `npx -y mcp-bastion`

Memory the human governs: vaults separated by domain (code, notes, journal) on your own machine, hybrid retrieval (BM25 fused with vectors by RRF), and a declared vault list, so a vault left out cannot be read by mistake. Also reads what the OTHER coding agents on this machine wrote to disk, and flags when two are live in the same git worktree. Needs the Mnemosyne OS desktop app running. `npx -y @mnemosyne_os/mcp`

Chestny ZNAK (Russian mandatory product marking, GIS MT and SUZ) API for AI assistants: marking codes, emission orders, circulation documents and code checks through 33 schema-driven methods with a read/write/destructive safety gate. PyPI (`uvx chestny-znak-mcp-ru`).

PostgreSQL over MCP, including databases behind an SSH bastion.

Delegate real-world actions from Claude Code, Codex, or any MCP client to [Hermes Agent](https://hermes-agent.nousresearch.com/docs) — research, browser workflows, messaging, scheduling, and Hermes skills/tools — instead of reimplementing them in the coding agent. Conservative safety policy downgrades risky `execute` to `request-approval`; small surface (`hermes_run`, `hermes_plan`, `hermes_presets`, `hermes_status`). MIT.

French and European case law (Conseil d'État, Cour de cassation, courts of appeal, first-instance courts, Conseil constitutionnel, CNDA, ECHR, CJEU), linked article by article to consolidated legal texts as they stood on any date: codes, statutes, the Journal officiel, EU law and treaties. ~3.8M decisions and ~3.7M articles in one database, refreshed daily, hybrid lexical and semantic search. Hosted endpoint at `https://librejustice.fr/mcp` (OAuth), or run `python3 mcp/lj_mcp.py` with an API key, standard library only.

DM / IM layer for AI agents over the A2A 1.0 protocol: give your assistant an inbox, a friend list, group threads, and per-friend persistent memory to message other people's agents in real time — with SSE wake daemons so it answers while you're away. `pip install agoradm-mcp`.

The Figma desktop app as an MCP server. Gives AI agents the full Plugin API on the open file, returns renders inline, reads design tokens, makes each call one undo step, and registers itself with every MCP client it finds. No cloud API, token or quota.

All 19 Oura Ring v2 collections in three tools, with no analysis done in the server. Paginates to exhaustion and reports the page count: one local day of heart rate is 1,231 samples across 2 pages, and a client that stops at the first returns 81% of them with nothing saying so. One-click `.mcpb` for Claude Desktop, and it runs on Oura's official sample data with no account.

MCP server for ICTCRM, an open source CRM with built-in telephony. Reads contact groups by default. Creating and deleting contacts, and adding them to a calling campaign, are only registered when `ICTCRM_MCP_ALLOW_WRITE=true`, so a default install cannot enrol anyone into an outbound campaign. Zero-install via `npx -y ictcrm-mcp`.

Trust score and guardrails for AI-generated code: static security rules, Docker-verified build/boot checks, and claim receipts that catch agents lying about tests. Tools: `scan_repo`, `guard_content`, `get_score`. Run with `npx --yes -p @elberacasa/umbra umbra-mcp`.

A fault-tolerant, stealth-enabled Model Context Protocol (MCP) server for web searching and content fetching

Options analytics: chains, IV rank, volatility risk premium, Greeks, gamma exposure (GEX), expected moves, and market screeners. Hosted remote connector or local install; requires an ApexVol plan.

Google Search, Bing, DuckDuckGo and Google Maps results as JSON with no API key (free daily allowance per network); Google AI Mode, AI Overview and Shopping with a key. `npx -y litescrape-mcp-server`.

All-in-one 24-tool MCP runtime and 180-skill library providing protocol-level C4 workflow gates, hard-gated command execution with security guardrails, and cognitive reasoning engines (Tree of Thoughts DAG, Red-Team Grilling, 5-Whys Root Cause Tracer, Context Compactor, Self-Evolution) for coding agents across Antigravity, Cursor, Windsurf, Claude Code, and Codex.

VK API for AI assistants: wall posts, communities, messages, market items, ads and stats through 373 schema-driven methods with a read/write/destructive safety gate. The agent searches methods in plain language instead of getting 373 tools. PyPI (`uvx vk-mcp-ru`).

Persistent coding memory across sessions, machines, and teammates. Provides MCP tools for searching and managing memories, optional cross-machine sync, and project sharing. OpenCode, Claude Code, and Codex integrations add automatic capture and context injection.

Zero-dependency CLI that connects any AI agent to every MCP server: one config, synced to Claude Code, Cursor, Codex, Cline, Windsurf and VS Code. Tool discovery drops from 71,929 to 581 tokens across 255 tools (-99.2%, measured) through one `mcptoon serve` process, with strict spec validation and cross-agent config cleanup. `pip install mcptoon`.

CNN Fear & Greed index for the US stock market: score, rating, seven component indicators, and about a year of daily history. Zero dependencies, no API key required.

Create and post link, banner, YouTube, and press-release ads on PageRankCafe, read placement performance, and query platform insights.

Check a citation against Crossref for retraction, correction, or expression-of-concern status before it goes into a paper, summary, or review — catches papers like Wakefield's retracted MMR-autism study, still cited 1,000+ times since its 2010 retraction. No API key required. Detection logic (checked against real Crossref data, not just documentation) is shared identically between a Python CLI/library, this MCP server, and a GitHub Action for CI. `npx -y citeguard-mcp-server`

MCP server for ICTExam, an AI exam authoring, delivery and auto-grading platform. Reads exam papers, classes, subjects, the teacher gradebook, and per-question item analysis (difficulty, p-value, average mark, full and zero credit counts). Read-only by default: parsing a question paper with AI, publishing and unpublishing are never registered with the model unless `ICTEXAM_MCP_ALLOW_WRITE=true`. Zero-install via `npx -y ictexam-mcp`.

Deterministic EVM bytecode capability intelligence, EIP-1967 proxy resolution, gas recommendations, and preflight safety intelligence for autonomous agents on Base (`Chain ID: 8453`). Supports stdio and hosted SSE. `npx -y m2m-sentinel-sdk`

Web browsing superpowers for AI agents: 13 MCP tools (scrape, extract, crawl, map, search, academic papers, batch, research, monitor, session). 3-tier auto-fallback ladder with free Cloudflare bypass, no API keys. Self-hosted Firecrawl alternative.

A local-first stdio MCP server for building token-efficient codebase context, with live preview, Git scopes, MCP-enforced secret redaction, and syntax-aware compression.

Color-vision accessibility. Check whether a palette or an image is colorblind-safe and name the conflicting pairs, generate colorblind-safe palettes (Okabe-Ito seeded), recolor an image as protanopia/deuteranopia/tritanopia renders it, and generate Ishihara-style test plates. Built on Machado, Oliveira & Fernandes (2009) + CIEDE2000, published open access at doi.org/10.5281/zenodo.21310578. Runs locally over stdio, no network calls. Install: `npx -y cvdsafe-mcp` and `npx -y colorblind-mcp`.

Generate AI images, video, voiceovers, avatars and UGC ads through 50+ models via fattly.app

Reads the embedded images other Excel servers drop: diagrams and screenshots come back as `ImageContent` mapped to the cell they sit in, so specs where the workflow lives in a picture are actually readable. Also surfaces the formatting that carries meaning (bold, strikethrough, highlight and font colors) and skips hidden rows/columns unless a visible formula depends on them. Write support with atomic saves. `uvx excel-vision-mcp`.

3D Visualizer: inspect, compare and export point clouds, meshes and calibrated depth data, with interactive previews in WebGL-capable MCP Apps clients. Supports labeled selections, measurements, NumPy/PyTorch inputs and COLMAP depth.

Official [Linkly](https://linklyhq.com) URL shortener server: create branded short links, read click analytics by country/platform/referrer, manage custom domains and click webhooks. Hosted at mcp.linklyhq.com with OAuth (no API keys); listed in the Claude connector directory.

Yandex Metrika (Яндекс Метрика) — complete API coverage: all 108 methods of the Stat, Management and Logs APIs as one tool each, generated from a spec parsed out of Yandex's own documentation, with a drift test that fails when the API changes. Writes disabled by default, tool annotations on every tool, response size ceiling with declared truncation. `npx -y yandex-metrika-mcp-server`

Search CuddlyNest for hotels in a destination and read live room options, prices, availability and cancellation policies for a specific hotel, from public listing pages. Hosted (Streamable HTTP, no auth) and on npm as `cuddlynest-mcp`; in the official MCP Registry as `io.github.mafedelahoz/cuddlynest-mcp`.

GitHub Actions health checkup: prices wasted CI compute, names flaky tests from job logs, deep-dives slow runs, and lints workflows against 21 rules with safe auto-fix previews. Read-only tools wrapping the gha-doctor CLI; listed in the MCP Registry.

Drive the Gearotons M17, an open-source closed-loop NEMA-17 servomotor, from plain English over RS-485: discovers serial ports, auto-detects every motor on the bus, and exposes the firmware's full command set as tools. Mock backend needs no hardware. `uvx --from servomotor-mcp servomotor-mcp`
