Development MCP Servers

A local MCP hub that lets your Claude Code agents talk to each other: message, nudge in the terminal, and coordinate through a web dashboard.

x402 preflight and trust layer for autonomous agents

Discover powerful AI agents, invoke them instantly, and verify every result with Ed25519 cryptographic proofs. Nine tools — five free, four billed — all protected by OAuth 2.1.

Let your agent operate your infra without seeing your secrets. Structure syncs to cloud, secret values never leave your machine.

E2LLM — structured browser perception for AI E2LLM turns any live web page into SiFR: a compact, deterministic, LLM-readable model of what's on the page, what it means, and what can be done with it. Perception is the product. Action is available when you need it — always explicit, always gated. Works as a hosted remote MCP server with the AI you already use. There's no local server to run — a browser extension pairs your live browser to the server, so perception and action happen in the real browser you're already signed into.

Domain intelligence for DNS, WHOIS/RDAP, TLS, reputation, valuation, and brand protection.

300+ tools that connect AI assistants directly to the Godot editor. Build scenes, write scripts, test gameplay — all through natural language.

Accessibility testing + AI fixes for coding agents: free local WCAG scans, framework-aware fixes you apply in your own code, a vision pass axe can't do, one-call fix verification, and full audit reports (npx @webability/mcp).

Token-efficient MCP server for Odoo 17/18/19 development. It gives AI assistants structured access to your Odoo codebase for discovery, search, model/view analysis, XML checks, and scaffolding patches.

Find and fix web accessibility (WCAG 2.2, ADA, Section 508, EAA, AODA) issues from your coding agent — scan any URL/HTML with 3 engines, framework-aware fixes, verify, vision audit, and auditor-ready reports.

AI Localization Agent adds professional localization. Instead of loading large i18n files into the AI's context, it translates them server-side via MCP (the ai-l10n-mcp package, built on the ai-l10n SDK and CLI), saving tokens and keeping the agent focused on coding. It preserves file formats, placeholders, and existing translations, supports 165 languages, applies persistent glossaries and custom linguistic instructions, and translates only changed strings for fast, production-ready localization.

Operate self-hosted OpenClaw and Hermes agent fleets on Docker or Kubernetes through Nora.

Threat intel for AI agents: CVE lookups (NVD + CISA KEV), package vulnerability checks (OSV), malicious URL detection (URLhaus), and IP reputation (AbuseIPDB).

Domain & company intelligence for AI agents: RDAP registration, DNS, email deliverability, tech-stack fingerprinting, and subdomain discovery. No API keys.

Zero-Trust Data Sanitization (ZTDS) local PII and secrets scrubber for secure LLM pipelines.

Security-first WordPress MCP server for Claude, ChatGPT, and Gemini. API key + OAuth 2.1 auth, per-tool capability gating, full activity log. 127 tools covering posts, pages, media, WooCommerce, Elementor, ACF. Free on wp.org.

MaxoPerf Performance Testing MCP

MCP tools for agent security audits and OG images, paid per call in USDC over x402 on Base

MCP server for Xray test management plugin for Jira. Avoids the problem of slow Jira/ Xray combination. Can bring an entire test suite faster than manually adding. Can integrate AI testing as this is able to update test cases as well. Why MCP and not a skill? MCP communicates well with Atlassian MCP.

An engineering governance and safety control plane for AI coding agents to enforce strict SDLC discipline, quality gates, and security branch protections.

A deterministic pre-action authorization gate for AI agents that checks each action against a signed mandate before it executes and writes a cryptographically signed, tamper-evident decision record.

A secure, read-only MCP server for querying MySQL, PostgreSQL, and Redis datasources

Free public MCP for AI agents — 193 tools, 44 workflows. No API key. JSON Schema, semver, secrets scan, OpenAPI, cron, hash, regex.

Discovery, OAuth handoff, and project MCP routing for Spala backend projects.

Connect every MCP server without paying the context-window tax.

Score CLAUDE.md/AGENTS.md, validate clarx-manifest.json, generate CI workflows, and pull repo scan findings into Cursor, Claude, or Grok.

IDA Pro MCP fusion for reverse engineering with 76 tools, SQLite cache, and multi-binary headless IDA analysis.

A local-first, multi-provider cost meter for LLM usage, exposed as MCP tools. Captures every call into a local SQLite ledger and lets any coding agent query spend, compare providers, and get recommendations — no cloud, no account. First-class support for Chinese providers (Qwen, DeepSeek) alongside Anthropic and OpenAI.

Security, control & observability layer for AI agents: pre-tool policy enforcement (allow/block/require_human_approval) + append-only JSONL audit logs. Wraps any stdio MCP server via drop-in sidecar. Apache-2.0. By BizDNAi.

Local-first code retrieval for AI agents — cuts codebase context from thousands of tokens to a few hundred, with zero hallucinated file paths.
