Model Context Protocol (MCP) Server Directory

Outbound voice is a mainstream agent capability in 2026 — Google's shopping agent calls stores and consumer callers navigate IVR menus. This MCP server — twilio-voice-mcp — gives any agent the same capability as governed tools: place outbound calls, speak text with AI disclosure, navigate IVR menus, capture transcripts, and report completion. Built with FastMCP in TypeScript with inputSchema JSON definitions, an mcpServers config, and an OAuth 2.0 / API-key security guide.

The BenchLM August 2026 leaderboard is the deployment guide for agent builders: Claude Mythos 5 tops the composite at 83.2, Qwen3.8 Max leads open weights at 79.9, and MiniMax M3 sits at 68.8. This MCP server — benchlm-mcp — exposes that leaderboard to agents as governed tools: query model scores by benchmark, compare two models, and pick the cheapest model that clears a quality threshold. Built with FastMCP in TypeScript with inputSchema JSON, mcpServers config, and an API-key security guide.

Inspired by the MCP 2026-07-28 specification (released July 28, 2026, stewarded by AAIF under the Linux Foundation), this dispatch builds stateless-mcp, a Python FastMCP server on the new stateless core: initialize and Mcp-Session-Id are gone, Mcp-Method/Mcp-Name headers drive routing, results carry ttlMs/cacheScope cache hints, MRTR (SEP-2322) handles elicitation, and the Tasks extension (SEP-2663) powers poll-based tasks/get.

Inspired by Cloudflare's August 5, 2026 Identity-Aware AI Gateway launch — which ties every outbound AI request to a verified Access identity via cf.user_id — plus the August 14, 2026 Cloudflare One MCP traffic detection wave (is_mcp selector, MCP Portal classification), this dispatch builds cloudflare-one-gateway-mcp, a FastMCP TypeScript server that registers agent identities, attaches identity headers, queries per-identity usage, sets model policies, and inspects detected MCP traffic.

SKALE's Agent Pit (Aug 12, 2026) established paper trading as the training ground for prediction-market agents. This MCP server — polymarket-mcp — gives agents the same discipline as a tool surface: read markets, order books, and positions in paper mode by default, then graduate to live orders only behind an explicit mode flag with position caps. Built with FastMCP in TypeScript with inputSchema JSON, mcpServers config, and an API-key security guide.

Chainlink for Agents (Aug 14, 2026) made verified data feeds and CCIP cross-chain settlement first-class resources for autonomous AI agents. This MCP server — chainlink-mcp — exposes those resources as governed tools: read price feeds, check token balances, inspect cross-chain transfer status, and submit CCIP transfers behind an explicit approval gate. Built with FastMCP in TypeScript with full inputSchema JSON definitions, an mcpServers config, and an OAuth 2.0 / API-key security guide.

Inspired by SUPERAGENT 3.0 (August 11, 2026), the AI business partner for insurance agencies, this dispatch builds agency-ops-mcp, a FastMCP TypeScript server exposing read-only quote data, policy and CRM lookup, and compliance status to agents. Write tools for quote generation and policy updates are gated behind OAuth scopes plus a human approval gate, and every action is written to an append-only audit trail.

Inspired by Featured's July 2026 MCP server for PR agencies, this dispatch builds pr-media-mcp, a FastMCP TypeScript server that lets agents monitor press mentions, track journalist and outlet sentiment, manage pitch outreach queues, and draft response drafts. Read tools are always available; write tools — send pitch, update contact — are gated behind OAuth 2.0 scopes plus a human approval gate, and every action lands in an append-only audit trail.

Inspired by Microsoft's June 30, 2026 read-write agent shift, this dispatch builds rw-boundary-mcp, a FastMCP TypeScript server wrapping office/document APIs. Read tools are always available; write tools require a scope token plus an approval gate, and every mutation is logged to an append-only audit trail.

Inspired by Kredily 3.0's KAI launch on August 14, 2026, this dispatch builds payroll-hr-mcp, a FastMCP TypeScript server exposing read-only payroll overview, attendance, statutory compliance, and pay-slip queries to agents. Write tools — payslip runs and reimbursement approvals — are gated behind a human-approval workflow with OAuth 2.0 enforcement.

After Google deleted three ADK workflows (Aug 4, 2026) over an agent-to-agent privilege boundary failure in CI/CD, agent-safe pipelines are the security story of the summer. This guide builds gh-actions-sec, a FastMCP TypeScript server that gives agents read-only visibility into GitHub Actions posture: workflow permissions, secret exposure, action allowlists, and run logs — so a CI/CD agent can audit and harden pipelines without ever holding write credentials.

MongoDB launched the Atlas Managed MCP Server on August 14, 2026, making live operational data a first-class resource for AI coding agents. This guide builds atlas-mcp, a FastMCP TypeScript gateway that exposes read-only tools for querying Atlas collections and Atlas Vector Search, with inputSchema JSON contracts, result caps, field allowlists, and OAuth 2.0 / API-key security — the governed pattern teams need before agents touch production data.
