Custom MCP Server Development
Custom MCP server development: expose your app, CRM or ERP as typed tools for any MCP-compatible AI assistant, with OAuth 2.1 and audit logs.
A custom MCP server turns your application into tools that any MCP-compatible AI assistant can discover and use safely. We design the tools, implement OAuth 2.1 per end user, enforce your data permissions and deploy it on the edge — so your customers and your team can operate your product from their AI assistant.
What we deliver
- Tool design: the right actions, typed schemas and read-only vs destructive annotations.
- OAuth 2.1 with PKCE and dynamic client registration, acting as the real user.
- Row-level permissions respected on every call, no service keys exposed.
- Streamable HTTP transport deployed on edge functions.
- Audit log, rate limits and observability per tool call.
- Testing with MCP-compatible clients and listing in MCP directories.
Typical tools by domain
- CRM: list_hot_leads, create_quote, schedule_followup.
- E-commerce: update_stock, list_orders, adjust_price.
- Messaging: list_pending_chats, summarize_conversation, create_ticket.
- Finance: generate_cash_report, list_pending_invoices, export_to_accounting.
No rebuild required
The MCP server sits on top of your current backend and reuses your authentication and permissions. Every platform we build is MCP-ready by design.
Frequently asked questions
What is MCP server development?
Building a server that implements the Model Context Protocol so AI assistants can call your application's capabilities as tools, with authentication and permissions.
MCP or REST API?
Keep both. REST serves your frontend and developers; MCP serves AI assistants with dynamic tool discovery, typed schemas and per-user OAuth.
Is it safe to expose our data to AI assistants?
Yes, when the assistant acts as an authenticated user, permissions are enforced on every query and every action is logged. That is our default pattern.
How long does a custom MCP server take?
Implementation takes 24 hours; legacy stacks add integration cycles depending on authentication.
