Model Context Protocol (MCP) Server Directory

On August 17-18, 2026 Alipay unveiled China's first full-stack agentic-commerce platform, letting merchants convert pages and service workflows into agent-ready Skills and MCP tools consumed through Ah Bao (10,000+ AI services, 5 smartphone brands, 16 automakers) over the AHA protocol suite and ACT 2.0 trust protocol. This dispatch builds commerce-orch, a LangGraph workflow that takes consumer intent, discovers Skills, performs a cross-provider A2A-style handshake, gates everything behind a spend-ceiling trust layer, executes payment and fulfillment, and appends every decision to a hash-chained audit ledger.

Tencent Cloud's TencentDB Agent Memory crossed 20,000 GitHub stars in 90 days (August 13, 2026) and shipped Team Memory, extending long-term agent memory from a single user to a whole team - conversations, documents, code, and institutional knowledge shared across agents. This dispatch builds team-mem, a LangGraph workflow with a memory-writer that extracts durable facts into a vector + knowledge-graph + KV pool, a memory-reader that fuses vector similarity, entity linkage, and recency behind per-team namespaces and ACLs, and a conflict-resolution node that supersedes contradictions.

Y Combinator open-sourced QM (MIT license, GitHub org yc-software) as a multiplayer multi-agent harness built for a whole company rather than a single user - it runs YC's own accounting, legal, events, and engineering work, including developing QM itself. Cloud-first with native Slack and web interfaces and model-agnostic across Pi, OpenCode, Codex, and Claude Code. This dispatch builds company-harness, a LangGraph workflow with a task intake router, a role router dispatching to role-appropriate agents on swappable model backends, an approval board for cross-role decisions, unified observability and audit, and a self-improvement loop that files tasks back into the queue.

In the week of August 19, 2026, Cloudflare launched Kitesurf, a browser runtime built for AI agents on the Workers platform, claiming roughly 3-7x less CPU and memory than Chromium while passing more than 235,000 web platform tests. We compare it to headless Chromium and Playwright, price the memory tax on agent farms, and show the Worker API shape for agent loops.

Tencent Cloud's TencentDB Agent Memory has passed 20,000 GitHub stars within 90 days of open-sourcing, as of August 13, 2026, and the same release adds Team Memory so shared agents can share conversations, documents, code, and institutional knowledge. We map the agent memory stack, the hybrid vector-plus-KV-plus-graph retrieval design, the governance risks of shared memory, and the token economics.

Y Combinator open-sourced QM, an MIT-licensed multi-agent harness for running a whole company, and runs its own accounting, legal, events, and engineering work on it. It is cloud-first with native Slack and web interfaces, and model-agnostic across Pi, OpenCode, Codex, and Claude Code. We compare it to single-user coding agents and enterprise platforms, map the intake-router-approval-observability architecture, and price the four-department ROI.

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.

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 August 17-18, 2026, Alipay unveiled China's first full-stack agentic commerce platform in Hangzhou, letting merchants with no AI convert pages and workflows into agent-ready Skills and MCP tools. It connects to Ah Bao, the consumer agent with 10,000+ services across eight categories, and ships a full protocol suite (AHA plus ACT 2.0) for audited, intent-verified agent transactions. We break down the stack, the protocol comparison, the merchant ROI math, and a sample skill manifest.

On August 13, 2026 OpenAI previewed Ultrafast, a service tier running GPT-5.6 Sol up to 14x faster on Cerebras wafer-scale engines at 750 tokens per second. This dispatch builds fastres, a LangGraph incident-response workflow with a latency-critical fast path, a hot diagnostics cache, a premium-budget guard, and degraded fallback to standard inference. It routes S1/S2 events to the fast tier, verifies root-cause hypotheses, drafts a runbook, gates on human approval, and closes with a post-incident review.

Anthropic reported its unreleased frontier model made significant progress on the Riemann Hypothesis by testing 650 ideas across 60 subagents with 31 million tokens, formalizing the confirmed findings in Lean. This dispatch builds leanverify, a LangGraph formal-verification workflow that decomposes a conjecture, fans out parallel research subagents, gates every promising lemma on a Lean compile, dedupes failed ideas in a shared registry, and publishes a verified-claims ledger.

On August 11, 2026, OpenAI made Daybreak cyber capabilities available through Amazon Bedrock. Daybreak Blue wraps GPT-5.6 Sol and other frontier models with safeguards for authorized defensive work; Daybreak Red provides purpose-trained models for vulnerability research, exploit validation, and security testing. We map Blue vs Red, diagram an agentic security-triage pipeline with a human approval gate, and lay out the access-tier, audit-log, and sandboxing requirements for running cyber models in an enterprise. Authorized and defensive use only.
