MCP servers agency for enterprise

Model Context Protocol · robust integrations between LLMs and your systems

We design and implement MCP servers (Model Context Protocol) that expose your enterprise systems (ERP, CRM, DB, own APIs) to LLM agents from Claude, GPT and others. With strict validation, permission control and audit.

When it fits · when it doesn't.

We publish this list to qualify together if we fit. If not, we save you time.

✓ FITS IF…
  • You have LLMs (Claude Code, internal agents) needing controlled access to your systems
  • You want to expose internal APIs to AI agents in a standard, auditable way
  • You will build multiple agents/tools sharing access to the same systems
  • You require fine governance (which tools each agent sees, with what permissions)
  • You prefer open standard over ad-hoc integrations per project
  • You're in the Anthropic ecosystem (Claude, Claude Code) or want to prepare for its mainstream arrival
✗ DOESN'T FIT IF…
  • A single agent with 2-3 ad-hoc tools (direct integration is simpler)
  • Microsoft-first environment where Copilot Studio or Semantic Kernel fit better out of the box
  • Cases where volume doesn't justify a standard layer
[ Process ]

How we do it.

01 Week 1-2

Systems discovery + governance

We identify which systems to expose (ERP, CRM, DB, APIs, filesystem, own tools), which operations are safe vs sensitive, and permissions matrix per agent/role.

02 Week 3-4

MCP server design and implementation

MCP server with official Anthropic SDK (Python/TypeScript). Tool definitions with strict Pydantic/Zod schemas. Authentication, rate limiting, structured logging.

03 Week 5-6

Claude/agent integration + testing

Server connection with Claude Desktop, Claude Code or own agents. Automated test suite. Agent decision evaluation with human in the loop.

04 Week 7-8

Deployment and observability

Deployment in your infra (Docker/K8s/serverless per case). Usage dashboard, cost per tool, anomaly alerts. Operational documentation.

[ FAQ ]

Technical decision-maker questions.

What's the difference between MCP and direct API integration?

MCP (Model Context Protocol) is an open standard from Anthropic (2024) defining how LLMs connect to external systems. Advantage over direct integration: a single standard protocol reusable by multiple agents/clients (Claude Desktop, Claude Code, own agents, other MCP-compatible tools).

With direct integration each agent reimplements connection to each system. With MCP the server is implemented once and any MCP-compatible client consumes it. As the MCP ecosystem grows (Anthropic, IDEs, agent platforms), this approach scales much better.

Trade-off: for 1-2 point tools, direct integration is simpler. MCP makes sense when tool count grows or there are multiple consumers of the same server.

Does it only work with Claude or also with GPT / Gemini / open source?

MCP was created by Anthropic but is an open standard. Today Claude (Desktop, Code, API) is the most mature consumer. Other clients are adopting it: Cursor, Zed and various agent platforms support it.

GPT and Gemini don't support it natively yet (August 2026) — they use their own systems (function calling, GPTs, extensions). It's possible to build MCP → OpenAI function calling adapters, but it's not native.

Our recommendation: if going all-in with Anthropic ecosystem, MCP is natural. If multi-model, consider exposing the same systems via multiple protocols (MCP + OpenAI functions + classic REST) from a common backend.

How do you guarantee security on an MCP server exposing critical systems?

Three layers: (1) strong MCP client authentication (OAuth 2.0 or mTLS), (2) granular authorisation per tool (permission matrix per role/agent), (3) strict input validation with Pydantic/Zod schemas rejecting any malformed or out-of-range request.

Additionally: per-client/tool rate limiting, logging of all calls with full context (which agent, which tool, which parameters, which result), and exportable audit for compliance review.

For tools performing sensitive actions (payments, client notifications, master data changes), we always design human-in-the-loop via agent interruption or explicit confirmation.

How much does an enterprise MCP server cost?

Typical pilot (MCP server + 2-3 exposed systems + Claude integration + observability): €25-60k in 4-8 weeks. Minimum monthly operating cost (infra + monitoring): €200-800/month depending on volume.

For more complex servers (10+ systems, fine governance, high availability, regulatory requirements): €60-150k and €800-2,500/month operational.
