Development MCP Servers

Gives coding agents the props, examples, CSS variables and Agent Skills for the Bestax React component library (Bulma v1). Runs offline.

Local repository check for AI-built apps on Vercel + Supabase: RLS gaps in migrations, a service role key in client code, env var drift and Stripe webhooks without signature checks. Advice, not a gate.

Local proxy in front of any MCP server: journals every tool call with secrets redacted, holds risky calls for your approval, quarantines changed tools; the journal is tamper-evident with an external anchor.

Roslyn MCP server and CLI for C#/.NET code intelligence: semantic code analysis and navigation for coding agents - callers, change impact, implementations, dependency injection, tests, side effects, dead code and token-budgeted context. Runs locally over stdio, no telemetry. Closed source; free for individuals, education and organizations below the license thresholds.

Connect customers' custom domains to your product: guided DNS setup, verification and certificates, managed from DoDomain. Remote server with OAuth sign-in.

Call a catalog of ready-to-use APIs through one upAPI account and key, without signing up for each upstream service. Remote server with OAuth sign-in.

Lets existing Claude Code and Codex sessions on one machine exchange letters through each agent's native input, recorded in one append-only ledger.

Review visual regression builds, approve or reject screenshot changes, and manage SnapVisor projects. Remote server with OAuth sign-in.

AI user personas test your product, prototypes and previews in a real browser and return screenshot evidence.

Manage uptime monitors, incidents and status pages, and read check results, in Uptimely. Remote server with OAuth sign-in.

Deterministic verification API + MCP tools for AI agents — invoice checks, data cleanup, lead scoring, contract extraction.

Independently verify an agent's output before you pay: structure, formats, ranges and cross-field rules, with a signed attestation and receipt. 3 free calls a day, then x402 v2.

Permissions infrastructure for AI agents — approval gates for every write your agent makes, with a tamper-evident audit log.

Hosted, read-only, no sign-in (https://viberaven.dev/mcp). Explains VibeRaven finding ids and returns launch guides and checklists for Vercel + Supabase apps. It never reads your repo.

Live Kestra plugin schemas, blueprints and docs for AI agents that build Kestra workflows

MCP server (via Apify) that checks and validates XML sitemaps: finds them via robots.txt, follows sitemap indexes and gzip files, extracts every URL with lastmod/changefreq/priority, diffs against a previous run, and optionally checks HTTP status. Broken sitemaps are reported, never skipped.

Zero-Trust Data Sanitization reference MCP server for Cursor and Claude Desktop. Local in-memory PII de-identification and deterministic surrogate tokenization (RFC v1.0).

Hosted SEO, AEO and GEO MCP on crawlwise.site: page audits, site crawls, AI-crawler reachability (GPTBot, ClaudeBot, Google-Extended), schema and vitals tools. Production endpoint: https://crawlwise.site/mcp (streamable HTTP, OAuth).

Put your important tool calls behind human approvals.

Let an AI agent read, write and scan the memory of running processes on Windows, Linux and macOS, Cheat Engine style: value scans, refinement and pointer chains.

Generate MCP servers from OpenAPI v3 or Swagger 2.0 specs in TypeScript, Python or Go. Each route becomes a typed tool, with incremental regeneration that preserves custom code.

Signed receipts for declared AI-agent workflow steps. Hash files locally; prepare and verify for free. Issue a receipt for 0.002 USDC via x402 on Base. HTTP, MCP and A2A.

Draft Dynamics 365 F&O and Business Central mockups from your AI agent.

Architecture diagrams, explanations and Mermaid source for any public GitHub repository.

Did it really happen? Independent Ed25519-signed receipts for AI agents: is a page online, does a domain exist and to whom, can an email receive (no mail sent), heartbeat + did my scheduled task run. Stateless Streamable HTTP MCP server, no account, free during launch then 1 cent per call. Verify any receipt for free.

PDF to Markdown by lintlab: convert public PDF URLs into page-aware Markdown or plain text with links, metadata and simple tables for RAG and search indexing; flags image-only pages (no OCR). A pay-per-event Apify Actor, used as an MCP tool through Apify's hosted MCP server; needs an Apify token.

Build and analyze product adoption workflows in Flows

Create production-ready Spring Boot applications with Bootify via MCP - best practices included.

Native macOS app and MCP server that lets AI agents see and drive the Android Emulator and phones: screenshots, UI tree in dp, tap, dark mode, RTL, logcat.

Read-only website facts for agents: check_https diagnoses certificate problems and browser privacy warnings for a domain and its www variant; site_info returns the CMS, mobile viewport, role emails and phones a business publishes. Remote, no install, 10 free calls a day.
