MCP server directory

The SEO MCP server that acts on your data, not just reads it: crawl your site, find where you're invisible in AI answers, generate the meta/schema/content fix as a spec, and ship it as a PR from Claude Code or Cursor. Built-in DataForSEO keyword data and Google Search Console.

AI-to-CATIA Magic bridge for live SysML v1 models: 130+ MCP tools to query, audit, trace, and edit blocks, requirements, allocations, and diagrams in CATIA Magic Systems of Systems Architect 2026x over a local, air-gapped connection. FREE tier reads and audits; PRO/ENTERPRISE licences unlock writes and scripting.

Git-backed message bus letting coding agents on different machines coordinate: rooms are folders, messages are files, git history is the log, and there is no server — the transport is a private git repository you already own. Questions, answers, decisions, collaborative tasks with claiming and recovery, and delegated repository reviews prepared in isolated worktrees at pinned revisions. Items marked `needs: human` cannot be answered by an agent, only relayed to a person.

Yandex Wordstat (Яндекс Вордстат) keyword search-demand — top & related queries, demand dynamics, and regional distribution. Read-only, dual-flavor (Yandex Cloud Search API v2 / api.wordstat.yandex.net).

Read and convert documents (PDF, DOCX, HWP, HWPX, EML), edit PDFs (merge, split, rotate, compress, protect), resize and clean images, strip EXIF, cut out backgrounds, and generate QR codes. Runs entirely on your machine with no uploads. Each tool reopens what it wrote and reports page counts so broken output surfaces as a number, not a surprise.

Long-term memory across sessions over a folder of plain markdown files. Hybrid retrieval (BM25F + dense vectors + phrase proximity) with an explicit absence verdict: when the corpus does not hold the answer it returns no results and names the query terms that appear nowhere, instead of ranking a least-bad match as though it were one. Embedding model runs locally, nothing leaves the machine. MIT.

Shared, versioned project brain for coding agents: one `brain.klypix` file committed with the repo holds current decisions, corrections that supersede (archived, never deleted), evidence anchors that flag drift when cited code changes, and open questions. Sessions declare their task and files and are warned about exact-file overlap. Lifecycle hooks for Claude Code; MCP config + rules for Codex, Cursor, Gemini CLI, Cline and Copilot. `npx klypix-mcp install`

Static security scanner for Claude Code skills, plugins, and MCP servers — vet a dependency for malware (secret/env exfiltration, install-time hooks, prompt injection, committed binaries) **before** you install it. Static-only: it clones and reads files, never executes the scanned code. `npx -y github:epistemedeus/skillguard mcp`

Search and read AiWiki, an encyclopedia of AI-coding pitfalls and LLM privacy protection written from the AI's first-person perspective. 120+ entries with mechanism analysis and cited evidence (papers / vendor docs / CVEs), bilingual EN/中文. Content fetched live from the site index, never stale. `npx -y aiwiki-mcp`

Queryable UniFi API documentation (Network, Protect, Site Manager, InnerSpace, Mobility, Carrier Fabric) — endpoint search, field-level schema drill-down, and code examples in curl/Go/Node.js/Python/Ansible. Read-only: serves scraped docs, never touches a controller.

Talk to a self-hosted [Actual Budget](https://actualbudget.org): spending breakdowns, category trends, projections and budget-vs-actual, not just lookups. Writes are guarded: every delete previews what it will remove and waits for confirmation, and `ACTUAL_READ_ONLY=1` hides the write tools from the model entirely. Multi-currency with split transactions and residual reconciliation. `npx -y actual-budget-mcp` or `ghcr.io/henfrydls/actual-budget-mcp`

Local-first web reading with a tier ladder that escalates from plain HTTP to a real browser when a page pushes back. Pages as clean Markdown, whole-site crawls, keyless search, repeated page structure induced into rows, and a REST API. Attempts supported captchas on your own machine with optional local ONNX models, and parks the rest in a human dashboard. Labels blocked and low-quality pages instead of handing back a challenge screen as content. No API keys, no paid solvers, no telemetry.

Manage a local model machine: pull/remove Ollama models, switch the inference service between models, and run LoRA fine-tuning jobs. `pip install mcp-modelmanager`

Glint Render (by Moyu) — web rendering & evidence API for AI agents: screenshots, PDFs, OG images, monitoring, extraction and tamper-evident evidence. Free tier included. `npx -y ottersnap-mcp`

Fault injection + model-free reliability scorecard for MCP servers. Injects timeouts, malformed JSON-RPC, truncated & corrupted-but-valid outputs; grades `outputSchema` enforceability (31 servers, 265 tools — only 3% enforceable) + error conformance. `pip install mcp-drill[scan]` · `uvx mcp-drill scan -- npx -y @modelcontextprotocol/server-filesystem /tmp` · GitHub Action + badge. See [vs mcp-scan](https://timurrakhmatullin86.github.io/mcp-drill/vs-mcp-scan/).

CHP Profile B spend/HITL and tool-approval receipts. `npx -y @cubiczan/chp-mcp`

Neume's MCP server lets ChatGPT, Claude, Cursor and any MCP client make full AI songs with vocals. Describe a song or paste lyrics and Neume makes it; change the words of one part (5-30 seconds) and it is sung again in the same voice, keeping the melody; reimagine any song in a new style. Tools: generate_song, get_song_details, get_my_songs, get_song_parts, change_lyrics, reimagine_song, get_balance, plus audio-upload tools. Remote Streamable HTTP endpoint https://api.neume.io/v1/mcp with OAuth 2.1 sign-in (Neume account); the assistant confirms before using credits. Docs: https://neume.io/blog/neume-mcp-server.

Blawgy is a done-for-you SEO content service. It researches the keywords your customers search, writes articles with images and internal links, and publishes them to your site on a schedule. Published posts are watched in Google Search Console and refreshed when they slip. The Blawgy MCP server gives an AI agent everything the dashboard can do. Read traffic, rankings, AI mentions and indexing status. Run keyword research and read the results with volume, difficulty and intent. Add keywords to the content plan, move dates, pause and resume, change posts per week. Write an article now, edit the body, publish a draft, release a held post. Draft and approve smart updates to live posts. Change images, sync products, build location pages, edit settings, manage guardrails, webhooks and your team. Connect from Claude, ChatGPT or Cursor by signing in with your Blawgy account and choosing which sites the connection can reach and whether it can write. Headless agents use an API key as a bearer token. Agencies on a Blawgy partner plan reach every approved client site from one connection. Deleting, publishing, reverting, disconnecting and cancelling ask the agent to confirm first. Credentials are read only or read and write, stored as hashes, revocable in one click, and every call is logged. Agents share the same posts-per-week limit, credits and rate limits as the dashboard and never get admin access. Included on every paid Blawgy plan. Streamable HTTP at https://app.blawgy.com/mcp.

Bring saved project requirements, decisions and preferences into the AI app where you are working. Configure Memory lets an authorized assistant search relevant context in your Configure profile and save facts you ask it to keep. Connect to https://mcp.configure.dev/ using Streamable HTTP, then sign in through OAuth in a supported client. No local server is needed. Public initialization and tool discovery expose no account memories; profile reads and writes require authorization. The public connection package and skill are at https://github.com/configure-dev/configure-mcp-plugin . It is a wrapper for the hosted service, not its backend. Docs: https://docs.configure.dev/mcp/overview .

Aident Loadout connects Codex, Claude Code, Cursor, ChatGPT and other MCP clients to 1,000+ apps and 400+ expert-built Skills through one reusable setup. Credentials stay in Aident Vault; every action is logged in Audit.

Execution safety for AI agent actions. `ctrlrun mcp-operator` exposes the approval queue as tools (`list_pending_approvals`, `approve`, `deny`, `resolve`, plus `receipts`, `effects`, `stats` and `inspect_action`), so the human who has to answer a held action answers it from the assistant they are already in; read tools answer without a credential and write tools refuse without one that names a person. Separately, the gateway proxies any MCP server so every tool call is checked against a YAML policy before it runs: allow, hold for a human, or deny. Approvals are single-use and bound to the hash of the exact action, one logical effect runs at most once across processes and hosts, and an unknown outcome is recorded AMBIGUOUS rather than FAILED so a blind retry is refused. Every attempt leaves a hash-chained JSON receipt. Apache-2.0. `pip install ctrlrun`

Local-first durable memory and session continuity for AI agents. Pure-Rust kernel with ambient governance and a hash-chained audit ledger; one NLU-routed meta-tool keeps the agent-facing surface small. Zero telemetry — memory lives on your own hardware, with backup/export/import across devices. Install: `npx whitemagic-mcp`.

Prices every Claude Code and Codex session already on disk and lets the agent ask what it's spending mid-session: cost by session, sub-agent and model, week-on-week comparison, and plain-English findings with applyable patches. No proxy, no API key, nothing leaves the machine. Install: `brew install --cask magna-nz/tap/tallybook`.
