Design contract layer for your codebase. Scans Figma, code, Storybook, and token files, reconciles conflicts, and serves a single machine-readable source of truth over MCP so every agent gets the same authoritative design rules before it builds. Local-first — your code never leaves your machine.

Web Validator by DigestSEO validates HTML and CSS, audits technical SEO and accessibility signals, checks JSON-LD and bounded public links, and captures responsive screenshots. Install locally with `npx -y mcp-web-validator`; no API keys required.

Codebase intelligence for AI coding agents. Indexes a repo into a dependency graph, git history, defect-risk code health, auto-generated docs, and architectural decisions, served as 9 task-shaped MCP tools across 15 languages. Runs 100% local; hosted option available.

This project implements a [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) server for interacting with the ZenML API. The Model Context Protocol (MCP) is an open protocol that standardizes how applications provide context to Large Language Models (LLMs). It acts like a "USB-C port for AI applications" - providing a standardized way to connect AI models to different data sources and tools. MCP follows a client-server architecture where: - MCP Hosts: Programs like Claude Desktop or IDEs that want to access data through MCP - MCP Clients: Protocol clients that maintain 1:1 connections with servers - MCP Servers: Lightweight programs that expose specific capabilities through the standardized protocol - Local Data Sources: Your computer's files, databases, and services that MCP servers can securely access - Remote Services: External systems available over the internet that MCP servers can connect to

MCP server for Atlassian Jira and Confluence with schema-validated Markdown↔ADF conversion. Catches content-model violations at conversion time rather than silently dropping ADF-only nodes like panels, mentions, and layouts.

Local-first MCP server for AI content governance — 13 tools for model/content CRUD, validation, normalization, and i18n across any framework.

Kamai runs an MCP server so agent hosts like Claude, ChatGPT, Grok, Cursor, and VS Code can drive Kamai directly - create projects, ingest drawings, and read structured takeoff data from a conversation. Same primitives as the REST API, exposed as tools for your agents.

Local MCP server that shows AI agents which patterns your team actually uses, what files a change will affect, and when there is not enough context to trust an edit. 30+ languages, fully local.

Full Figma control: create shapes, text, components, set styles, auto-layout, variables, export. 80+ tools.

MCP server for RustChain blockchain, BoTTube video platform, and Beacon agent messaging. Wallet management, mining queries, bounties, video search/upload, and agent messaging tools. Install via `pip install rustchain-mcp`.

Trust & safety layer for x402 agent payments: before your agent pays an x402 endpoint, verify it is safe — liveness, scam/anomaly scan (payTo hijack, bait-and-switch, honeypot), and on-chain receiver verification. ~70% of x402 endpoints are dead or scams; only ~half of "healthy" listings work. Free /verify + an open Trust Score. `npx -y pulsefeed-x402-mcp`

> Magic MCP is now the 21st MCP. The Magic MCP server (@21st-dev/magic) has been replaced by the unified 21st MCP, installed via the 21st CLI — setup at 21st.dev/mcp. This package remains published as a thin compatibility proxy so old configs keep working. Or add it manually — it is a plain HTTP MCP server: > Old Magic API keys were reset. Keys issued by the old Magic console no longer work anywhere. Generate a fresh key at 21st.dev/mcp. npx -y @21st-dev/magic@latest API_KEY="..." still works: since v0.2.0 it is a small stdio proxy that forwards every MCP message to the 21st MCP server. Existing mcp.json entries that reference @21st-dev/magic keep functioning — but they now speak to the same server as the 21st CLI, with the full current toolset.
