A Model Context Protocol (MCP) server that provides analytics and insights for the scheduling software freispace. This server enables AI assistants (e.g. Copilot, Gemini) to query data within freispace, such as project statistics and planning related information. The freispace MCP Server connects any LLM with tooling capabilities to freispace to query analytical data. Media teams using freispace can leverage the MCP server to make planning data available to the entire company using the company-wide AI (e.g. Copilot), without users having to be on freispace or even know about freispace, as well as help post-production teams make data-driven decisions while scheduling and planning.

ScreensDesign MCP connects AI assistants to mobile-app research: real screens, recorded UX flows, onboarding and paywall examples, competitor discovery, App Store reviews, marketing creatives, and saved collections. Hosted Streamable HTTP endpoint: https://api.screensdesign.com/v1/mcp. Browser OAuth and a ScreensDesign Pro account are required. No local server package is needed. Website: https://screensdesign.com/mcp/ . Setup: https://screensdesign.com/mcp/setup . Public repository (documentation, registry metadata and optional companion skill): https://github.com/screensdesign-com/screensdesign-agent-skill . The hosted implementation is operated separately.

Run Codex agents from Claude Code through MCP and Channels, with live progress notifications, mid-task steering, and saved session continuation.

Checks live x402 routes across Base, Solana, and Algorand. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Remote MCP: https://402signal.com/mcp (x402-capable client required for paid routing).

Fork, break, and revert real VirtualBox VMs as MCP tools. Forks are linked clones (~0.1s) and revert restores a RAM snapshot in seconds. Drives GUI-only guests through the hypervisor with screenshot, click, scroll, type and keys, so an agent controls a machine with no SSH, guest agent, or network, including Windows XP. Windows host with VirtualBox required. `npx -y terrarium-mcp mcp`

MCP server + Chrome extension that drive the user's real, logged-in Chrome over a local WebSocket. 59 token-efficient web-dev tools: compact element refs instead of screenshots, server-side table filtering, visual regression, accessibility/SEO/security audits, network mocking. Also runs on ChromeOS/Crostini.

Self-improving skill memory for coding agents: skills that help get reinforced, unused ones fade on an Ebbinghaus decay curve. $0 write path (SQLite FTS5 + local ONNX embeddings, no LLM calls), bilingual EN/RU hybrid search, SHA256 tamper-evident history, deterministic LongMemEval benchmark in-repo (hit@5 0.871). 8 mem_* tools; deep Claude Code hook integration optional. `pip install skillmem`

120 US government open-data sources (EPA contamination and drinking water, FEMA flood and risk index, USGS, NOAA, FAA airspace, USACE levees and dams, FDIC, HUD, NRCS soils, county assessor rolls, state licensing boards) as agent-callable tools. Runs locally over stdio with `npx gov-data-mcp`; 12 dedicated tools plus `search-gov-data-tools` / `describe-gov-data-tool` / `run-gov-data-tool` to reach the rest. Every tool reports its own per-result price, so an agent can weigh cost before calling.

Free SEO + GEO (AI search) analysis, 13 tools: Core Web Vitals, structured data, security headers, mobile SEO, image audits, internal linking, and AI crawler access (GPTBot, ClaudeBot, PerplexityBot). No signup, no API key — run locally via `npx @rankcli/mcp-server` or use the free hosted endpoint at `mcp.rankcli.dev/mcp/free`.

CPFHub MCP is the MCP server for CPFHub.io, a REST API for looking up Brazilian CPF numbers (name, gender, birth date), plus a real-time lookup from the official Receita Federal source. Remote endpoint: https://api.cpfhub.io/mcp (auth via x-api-key header). Tools: lookup_cpf, get_quota_info. Free plan with 50 credits per month; paid plans from R$19.

An edge firewall for AI agents to securely expose internal PostgreSQL databases and APIs with strict validation.

Creates a live webhook endpoint an agent can receive on, then reads the real deliveries back. The first call works without an account or a key, and the endpoint keeps working after the session ends.

Two deterministic, rule-based analysis engines for agents: cloud billing cost anomaly detection (rolling-median + MAD, resistant to the masking effect) and auditable architecture risk scoring (single point of failure, coupling, scalability gap) with a rule-by-rule breakdown for every score. `uvx cloudsealed-mcp`

Run efficiency for Claude Code sessions: the share of paid tokens that became model output versus re-reading context already sent, by tokens and cost-weighted. Reads local transcripts, makes no network calls.

Verify AI-agent revenue claims: trustlessly recompute a Merkle proof and check it against an on-chain anchor (x402 / agentic payments).

Fail-closed approval layer for unattended agent runs: `guard` evaluates each declared action against org policy before it executes (allow/warn/block/require-approval with one-click human approval), records every decision to a causal ledger, and adds plan preflight, scoped delegation grants, and containment verdicts. `npx -y @dashclaw/mcp-server`

Agentic AI for business intelligence: company and contact discovery, verification, enrichment, business signals, lists and governed delivery. Remote Streamable HTTP with OAuth or API keys; mission_agent by default, granular tools with ?tools=all.

Hosted remote server with OAuth at `https://mcp.lettio.eu/mcp`, or run locally via `npx -y @lettio/mcp`. Sending is pinned to the signed-in mailbox, so an agent can never send from another address.

Shared, git-tracked memory for AI agents on the same codebase. Stores facts/decisions/gotchas in a `.ai-memory/` directory you commit to the repo — sync is git, no DB, no daemon. What one Claude/Cursor/Cline learns, the next one picks up automatically across users and machines. 5 MCP tools (`get_repo_memory`, `add_fact`, `list_facts`, `add_decision`, `add_gotcha`). Install: `uvx repo-memory-mcp --repo /path/to/repo`.

Attack-path engine for cloud and Kubernetes. Eight read-only tools let an agent list the reachable routes from internet exposure to sensitive assets, explain each hop and the evidence behind its probability, find choke points, and simulate cutting a relationship before recommending the fix. Connects to a running PerspectiveGraph: `perspectivegraph mcp --api http://localhost:8080`.
