A practitioner shares their experience with MCP (Model Context Protocol) servers for business work, detailing which ones provide real read/write capabilities (e.g., Postgres MCP, HubSpot MCP, PostFast) and which disappoint (e.g., Slack MCP, Google Ads MCP), while highlighting major security concerns like low OAuth adoption and high vulnerability rates.
Trying to figure out which MCP servers are worth wiring into my agent setup for business work, not coding. Anthropic's own numbers put the ecosystem at 10K+ active public servers (3,012 in the official registry), but community servers have 30-50% install failure rates and most of what I've tested is either demo-ware or read-only wrappers that can't take real actions. Asking here before I burn another month testing. What I've kept after 4 months. GitHub MCP for PR triage saves ~8 hrs/week but that's the coding side. For business work: Postgres MCP handles ~30 support tickets a week (agent reads DB, drafts reply, I approve). PostFast for social scheduling from Claude, 11 platforms including Google Business Profile at €10/mo, saves ~3 hrs/week of copy paste, though analytics are thin so I pair it with Metricool at $22/mo. HubSpot MCP for CRM is the best-supported one I found, full read/write. Tally for forms is free with 21 tools and OAuth setup takes 2 min. What disappointed. Slack MCP is fine for reading/summarizing but message posting without human approval feels risky. Google Ads and Meta Ads MCPs ship official servers but I keep them read-only after Claude fumbled a tool call near a live budget. Zapier/Make MCP add latency for stuff direct servers do better. Security is the bigger filter than features: only 8.5% of registry servers use OAuth (rest are static API keys or nothing), 15.4% don't even publish source code, and there were 7 CVEs against MCP implementations in 12 months including a 9.6 RCE in mcp-remote with 437K downloads. A scan of 1,808 servers found 66% had security findings. So I stick to vendor-maintained servers only. The gap I can't fill: a solid MCP for invoicing/billing ops (Stripe's is read-heavy), anything decent for inventory or ops management, and multi-agent orchestration across 5+ servers without the agent picking wrong tools ~20% of the time. What are you running that gives agents real write capabilities for business tasks?? Especially interested in finance/ops MCPs since that's where my stack has holes
A developer is building 402 MCP servers for AI agents and seeks community feedback on which paid microservices would be most valuable for making agents more useful.
This article explains the Model Context Protocol (MCP) for building pluggable AI agent architectures, detailing lessons from building an MCP server at Sentry, including OAuth 2.1 integration, designing agent-friendly tool interfaces, and current ecosystem limitations.
Raises concerns that MCP servers may introduce new architectural dependencies, questioning whether agents tied to specific server auth and implementations are truly portable.
A discussion on whether the Model Context Protocol (MCP) remains relevant as AI agents increasingly crawl websites or Swagger/OpenAPI docs directly, comparing the reliability and advantages of each approach.
MCP servers enable AI agents to offload deterministic tasks to trusted tools like BrainyCalc, ensuring accurate and reproducible results where LLMs may make errors.
