MCP Servers

Project-aware, read-only Nacos config & service-discovery server for Spring Cloud repos. Zero setup: auto-discovers every environment (dev/test/prod/...) from the repo's application/bootstrap files, with cross-environment key-level config diff. Single file, zero dependencies.

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.

Deterministic validation of AI-generated artifacts before acting on them: JSON Schema conformance, OpenAPI response conformance, SQL syntax per dialect. Typed verdicts with per-error fix hints. Hosted free tier with remote MCP endpoint; MIT, self-hostable.

All-in-one developer tool and MCP Server for Roku development, featuring ECP device control, automated channel sideloading, BrightScript debugging, and real-time log monitoring.

23-in-1 developer utility MCP server: web search, exchange rates, crypto prices, QR codes, JSON formatter, UUID, URL tools, domain check, RSS feeds, and more. 6 paid APIs via x402 micropayments ($0.003 USDC on Base). npx myclaw-toolkit

Local repo-intelligence index and MCP server for coding agents — "what a repository knows about itself." Hybrid BM25 + vector semantic search, a tree-sitter code graph (callers/callees/imports across Rust, TS/TSX, Kotlin, C/C++, Python) with an optional compiler-grade SCIP oracle, queryable git/GitHub history, and typed, source-anchored repo memories (Invariant, Decision, Risk, …) that persist across sessions. Every result carries provenance — confidence labels and coverage warnings. Keeps sourc

Design-fidelity checks for AI agents: compare a Figma frame (or any design screenshot) against the rendered implementation and get structured discrepancies with CSS properties and severity. Resolves a natural-language component description to a URL + selector in your codebase, screenshots it with Playwright, and compares via vision AI using your existing Claude Code or Codex subscription — no API keys. 90% mutation recall, zero false positives on its golden eval set. npx -y kiyas-cli mcp

MCP server for NowSecure Platform mobile security testing. List applications, pull remediation findings via GraphQL, and generate PDF reports locally (bypasses broken UI export). Published as nowsecure-mcp-server. npx -y nowsecure-mcp-server

Deterministic documentation-drift detection for AI agents. Validates a project's canonical docs against its actual code — no LLM guessing; every finding has a stable code and a suggested fix. Five read-only tools over stdio: guard, score, explain, verify-claims, diagnose. npx -y docguard-cli mcp

🎖️ - The official MCP server for PNTR free dev subdomains — register a .pntr.dev subdomain, manage its DNS records, receive email on a disposable inbox, and capture inbound HTTP requests for webhook debugging. Free tier, no key needed to start. Local stdio via npx @pntr/cli or hosted endpoint (https://api.pntr.dev/mcp, OAuth).

EOQ-based context economics for coding agents. Monitors LLM token cache with inventory theory, signals optimal session restart timing via live dashboard and terminal statusline. Zero context pollution — no metric ever enters the model's context.

Index any TypeScript/React repo (including monorepos) into a queryable code graph. Reverse queries (who-renders, who-calls, find-references), blast-radius analysis, dependency cycles, dead-code orphans, and symbol signatures — exposed over stdio. Install: npx code-graph-indexer.

Plug-and-play MCP server toolkit with semantic code search, natural language database queries, docs indexing, and OpenAPI introspection. One-command setup for Claude Code, Cursor, and Windsurf.

🎖️ - "The official MCP server for the Nahook webhook platform — trigger webhooks, inspect deliveries, retry failures, and manage endpoints from your AI assistant."

Breaking-change diffs for npm packages so coding agents stop writing code against outdated API knowledge.

Free Agent Signal Optimization scanner for website/API agent readiness. Scores discovery, identity, trust, commerce, reputation, and memory signals; validates robots.txt AI bot rules, llms.txt, agent.json, Google A2A agent cards, MCP server cards, API catalogs, OAuth metadata, x402, pricing, security.txt, status endpoints, and cross-file identity consistency. Returns ASO maturity levels, evidence, and prioritized fix plans. Local stdio or Glama-hosted, no API key required. npx -y @forgemeshlabs/

🎖️ - Official MCP server for Emailens, the rendering linter for email. Lint HTML email for rendering issues across 15 clients (Gmail, Outlook, Apple Mail and more), score CSS compatibility 0-100 per client, simulate dark mode, and get framework-native fix snippets for React Email, MJML, and Maizzle. npx -y @emailens/mcp

Generate and read PDFs for AI agents: a generatepdf tool (HTML, a URL, or a template + JSON → PDF) and a readpdf tool (a PDF → text/markdown). Run locally with npx @docweave/mcp or use the hosted streamable-HTTP endpoint. Chromium-rendered, priced per document.

Code-intelligence engine that indexes a repo into a persistent knowledge graph — functions, classes, call chains, HTTP routes, cross-service links. 159 languages via tree-sitter + Hybrid LSP, sub-ms structural queries, ~99% fewer tokens than grep. Single static binary, zero dependencies, 100% local. npx codebase-memory-mcp

Native stdio bridge for the hosted Delx Protocol MCP endpoint, with one-command client install, doctor checks and live tool discovery.

Secure host-level telemetry gateway enabling sandboxed AI agents to dynamically fetch container logs and track kernel resource metrics.

Reduced-motion / WCAG 2.2.2+2.3.3 verification for web animation: agents author validated specs; a deterministic compiler emits reduced-motion-safe, on-budget CSS. Keyless hosted endpoint (motioncatalog, motionvalidate).

Pre-flight dependency-upgrade impact analysis: reports exactly which of your code's API usages break before you bump a dependency, with line numbers, severity, and fix hints. Also verifies AI-written code against the actually-installed API to catch hallucinated calls. Static analysis only — never runs third-party code. Python + .NET. pip install bumpguard-mcp

Grounding / hallucination guard: verify a claim against evidence (Supported/Refuted/Not Enough Evidence) with a confidence + abstain flag, for RAG and agents. npx -y eleata-verify-mcp.
