Developer Tools MCP servers

Watch your coding agent work as a film: opens and replays the Agent Theatre stage for a repo.

Mock, record/replay, verify and chaos-test any HTTP, REST, gRPC or LLM dependency over MCP.

Design tokens, component source and WCAG checks for rendering any UI in a past design era.

Live, verified LLM API prices and deals: free models, discounts, compare, costs, price changes.

Entity-level code intelligence: semantic diff, impact analysis, blame, and context for AI agents

Arena by Dravensoft over MCP: the router, the references and every component document.

What went wrong with your own Ollama calls, in sentences with the fix. Local, read-only.

Turns an AI coding agent session into a reviewable Intent Document, validated against the diff.

Plan OpenAI Codex usage from local quota, banked resets and extra-reset forecasts.

Sandboxed shell exec for MCP clients: run untrusted agent commands in a gVisor container.

Generate clean markdown documentation for your code — one file, or up to 20 in one batch.

AI app builder and APK maker for Android. Create and edit apps without coding.

Get a second opinion on your code from every coding agent you have. No API keys.

Unlimited computation for agents. Results depend on your equipment; GPU optional.

CNCF release intelligence: typed changes from release notes; check_stack compares versions locally.

Deterministic SAST/SCA findings + fix guidance for your AI agent. Runs locally, no account needed.

Queryable UniFi API docs: endpoint search, schemas, code examples. No controller access.

Create and manage Form.io forms, resources, actions, roles, and projects from your AI agent.

MCP server for MDMA — exposes spec, prompts, docs, and package metadata to AI assistants.

AI-editable diagrams as code: draw from YAML, propose diffs a human applies, export SVG/Mermaid.

Deploy a site to its SFTP/FTP host from a coding agent. Changed files only, undo, live checks.

MCP gateway for QA/SDET work: Playwright, files, GitHub, Jira, Postgres & more in one connection.

Check locale files for broken placeholders, plurals and missing keys. Validators need no API key.

Search-first MCP server for JavaScript reverse engineering: 735 tools across 36 domains.

Mock OpenAPI specs locally, or log in to deploy hosted mocks on mockzilla.org from your MCP client.

Your runbooks as agent tools: scripts from runbooks.json served as typed, allowlisted MCP tools.

Drive the iOS Simulator from an agent: read the screen, tap/type/swipe, replay flows in CI.

Parallel Codex CLI workers from any MCP client: one git worktree each, state in SQLite, web board.
