Model Context Protocol (MCP) Server Directory

Cloudflare shipped Kitesurf (week of Aug 19 2026), a browser runtime built for AI agents that runs on Cloudflare Workers using roughly 3-7x less CPU and memory than Chromium while passing more than 235,000 web platform tests — a lightweight alternative to full headless Chromium for agent web automation. This dispatch builds browser-runtime-mcp, a FastMCP Python server exposing ten governed tools — open_page, get_text, click, type_text, screenshot, wait_for, fill_form, extract_table, session_state, close_page — where every call returns a compact accessibility-tree view instead of raw HTML to save tokens, with a concurrency/rate-limit guard, privacy mode (trackers/ads blocked by default), and a per-agent session sandbox.

On Aug 17-18 2026 Alipay unveiled China's first full-stack agentic commerce platform: merchants convert pages, products, and service workflows into agent-ready Skills and MCP tools, unified over AI payment, KYA trusted identity, risk management, and service fulfillment — with AHA for cross-agent/cross-device interoperability and ACT 2.0 for delegation, audit trails, intent verification, and payment channels. Ah Bao (Alipay's consumer agent, June 2026) already spans 10,000+ services across 5 smartphone brands (70%+ market) and 16 automakers. This dispatch builds agentic-commerce-mcp, a FastMCP Python server exposing eight governed tools — create_payment_intent, confirm_payment, issue_refund, verify_identity, create_order, check_fulfillment_status, get_merchant_skill, list_skills — with a spend-ceiling guard, a human-approval gate on irreversible actions, inputSchema, mcpServers config, and OAuth 2.0 signed/idempotent security.

Anthropic's unreleased frontier model tested 650 ideas across 60 subagents (31M tokens) on the Riemann Hypothesis — and the confirmed findings were formalized in Lean, making Lean the emerging proof-of-correctness gate for both math and AI code. This dispatch builds lean-mcp, a FastMCP Python server exposing five tools — check_lemma, compile_project, list_theorems, propose_tactic, check_import — with inputSchema, mcpServers config, and a localhost transport secured by OAuth 2.0-scoped registry tokens.

On Aug 13 2026 OpenAI previewed Ultrafast — GPT-5.6 Sol at up to 750 output tokens per second (~14x Standard), powered by Cerebras wafer-scale engines (900,000 cores, 44GB SRAM on one slab). This dispatch builds cerebras-fast-mcp, a FastMCP Python server exposing four governed tools — complete_fast, tokens_per_second, route_fast_vs_standard, failover_standard — with a TTFT latency guard, a per-request cost/jitter meter, inputSchema, mcpServers config, and OAuth 2.0 scoped-token security.

DeepSeek's Aug 16, 2026 peak/off-peak rate card made time-of-day a first-class LLM cost input. This guide builds cost-router-mcp, a FastMCP Python server that routes agent calls to the cheapest eligible model — with a routing engine, cost-table JSON, provider config, token-budget caps, fallback retries, and OAuth 2.0/API-key security.

Agents belong on the warehouse floor in 2026. warehouse-mcp is a production FastMCP Python server giving AI agents six governed tools — item lookup, stock levels, order picking, restock triggers, supplier status, low-stock alerts — with inputSchema, mcpServers config, OAuth 2.0/API-key security, and retry rules for unreliable WMS backends.
