Development MCP Servers

Monitoring your coding agent sets up and runs: catches production errors and bugs, finds the root cause, and fixes them over MCP.

Decode any US-market VIN, check NHTSA recalls, and look up verified buyer-paid car prices. Free, no auth.

Paid per call in USDC over x402: check a package for malware, known vulnerabilities, exploited CVEs and end-of-life dates, plus LLM prices. Signed answers, no account or API key.

Windows stdio MCP server for Mitsubishi GX Works2 PLC engineering. Provides CPU-scoped manual context, project inspection and diagnostics, Ladder/FBD editing, and versioned project artifacts, using the AI model supplied by the MCP client.

Lets coding agents hand summarising, field extraction, classification and OCR to the on-device model for Apple Foundation Models (macOS 27), free and offline.

Local stdio MCP server for phone and email validation: check_phone (numbering-plan metadata, not live carrier data) and check_email (syntax and DNS only). Invitation-only free beta.

Local task queue + live board so parallel Claude Code, Cursor and Codex sessions stop double-claiming work. Atomic claims, approve-the-plan gate, results linked to commits. One Go binary, SQLite, no account

Lets an AI agent debug from what actually broke in production. Connected to a Condux project, it can search the project's issues with the dashboard's own filters, open one with its latest stack trace and page through past occurrences. Tokens are scoped to a single project and read only by default

An open-source bridge that lets any AI agent drive your real, logged-in Chrome or Brave browsers, without opening a network port.

Ask your coding agent how to set up Claude Code, Codex, Cursor, Gemini CLI and more, get install commands for official MCP servers, and compare plugins, evals and pricing. Every answer is sourced from vendor docs.

Ask an AI assistant how your EU age checks are going. It reads Tessio.Cloud stats over MCP: pass rate against the previous period, trends, refusal reasons, the funnel and grouped outcomes. A stats:read key can never start a check or change a setting.

Website monitoring: uptime, SSL certificates, broken links, DNS, cron jobs and status pages.

79 tools for Solana memecoin traders and agents: pump.fun launches and bonding curves, rug and bundle forensics, token risk scores, wallet PnL, live prices, plus web and util tools. Free tier, pay-per-call via x402 USDC/SOL.

AI coding assistant for reasoning, debugging, and long coding tasks.

Error tracking, performance monitoring and logs for Laravel and PHP apps, by Spatie.

Bring focused JS/TS features from other repos into your app through MCP—with behavior checks and a patch you can review.

Lets coding agents check what their change did to the UI while they work, review a PR's screenshot diffs, and accept or deny baselines.

Configure and ship cross-platform and web3 games on iDos Games: live game config, tokens and NFTs, AI assets, task board and builds. Hosted server with OAuth; a local SDK server serves game modules and skills.

Hosted human-in-the-loop for AI agents: durable approvals, proposals, and choices that survive disconnects, reach any device via a review page, and leave an audit trail.

Human-in-the-loop for any MCP agent: native confirm, form, and display dialogs via MCP elicitation, plus a doctor that tests what your host actually supports. Free and local: npx -y elicitly

By Rene Turcios. Finds stale issue claims and parked fixes: claims aging with no PR, and finished work on fork branches that never became a PR. CLI and MCP server with tools stale_claims, parked_branches, issue_claim_status.

By Rene Turcios. Extracts a repo's hidden contribution gates (assignment first, claim first, DCO, vouch) from its docs into a machine-readable contribution-gates.json. CLI and MCP server with tools extract_gates, validate_gates, gates_badge.

By Rene Turcios. PR attention triage for contributors: ranks your open PRs by what needs attention, including changes requested, unresolved review threads, real failing checks, conflicts, and reviewer silence. CLI and MCP server with tools attention_report, list_my_prs, pr_status.

By Rene Turcios. Pre-flight checks for open-source contributions: is this issue actually landable? Verdicts (GO / RISKY / TAKEN / GATED / STALE), repo friction scores, and scan mode. CLI and MCP server with tools check_issue, scan_repo, repo_friction.

Query agent-reported interactions and daily reachability observations of MCP Registry servers.

Takes your coding agent (Claude Code, Codex CLI, Gemini CLI, Cursor) from an iOS app idea to the App Store: niche research, design, SwiftUI build, Supabase backend, subscriptions, ASO listing and TestFlight upload. 127 tools; anything that goes live waits for your approval.

Audit trail and traceability for AI agents. MCP gate: evaluate, ingest, request approval.

Build websites and apps with your AI agent. Preview, ask for changes, keep the source, and publish when you allow it. Publishing requires deploy permission.

Turn an API, database or documents into a hosted MCP server that Claude, ChatGPT, Cursor and VS Code can use. No code and nothing to host; an agent can create one from a public API spec with no account.

13 free utility tools for AI agents: web text extraction, markdown/HTML conversion, hashing, encoding, UUIDs, date math, unit conversion, JSON formatting.
