What I can deliver
- MCP servers exposing REST APIs, databases or internal services as typed tools
- Tool-calling agents for research, triage, classification, drafting and updates
- Multi-step workflows with structured outputs, memory/state and human approval
- OpenAI or Anthropic Claude integration in TypeScript/Node.js or Python
- Clear schemas, validation, allow-lists and safe write actions
- Retries, timeouts, idempotency, logging and cost-aware observability
- Local MCP setup, an API endpoint, background job or chat UI
Typical integrations
- Your own REST API or backend, so assistants can call it safely
- Systems like Jira or Salesforce, reached through their APIs
- Internal databases and knowledge bases
- Cloud services, background jobs and your own tools
Choosing a package
- Basic: an MCP server with up to 3 tools, or one focused agent
- Standard: connects an MCP tool layer to a multi-step workflow
- Premium: adds deployment, monitoring and documentation
Who this is for
- Teams that want Claude, Cursor or ChatGPT to use their product's API or internal tools
- Founders making their product reachable from AI assistants through MCP
- Operations teams automating triage, drafting or updates with an agent that has human approval
- Developers who want a reliable integration rather than a fragile demo
- AI engines
- GPT · Claude
- Languages
- TypeScript / Node.js · Python
How it works
01
Share the workflow and systems
Describe the workflow and the systems you want connected, so I can confirm the right package.
02
Design the tools and guardrails
Typed tools with clear schemas, validation and allow-lists, so the agent can do what you intend and no more.
03
Build, test and hand over
Retries, logging and observability built in, with a README (and deployment in Premium).
Common questions
Which AI apps can use the server?+
Claude Desktop, Cursor, Windsurf or ChatGPT can be connected to your own APIs, databases and tools, locally or through an API endpoint depending on the setup.
Can the agent take actions, or only read data?+
Both. Write actions are built with clear schemas, validation and allow-lists, and sensitive steps can require human approval so the agent never does more than you intend.
Which languages and models do you use?+
TypeScript/Node.js or Python, with OpenAI or Anthropic Claude models, depending on what fits your stack.
What is a custom MCP server?+
A custom MCP (Model Context Protocol) server is a small service that gives AI tools such as Claude, Cursor or ChatGPT structured access to your own API, database or internal tools, so the assistant can look things up or take approved actions.
How do I add a custom MCP server to Claude or Cursor?+
Once the server exists, you register it in the app's MCP settings, either as a local command or as a remote endpoint. Every package comes with setup notes or a README showing exactly how to connect it to Claude, Cursor or ChatGPT.
Can you build an MCP server for my existing API?+
Yes. That is the most common use: your existing REST API or database is exposed as typed tools with validation and allow-lists, so nothing needs to be rebuilt.
How much does MCP server development cost?+
Packages are fixed-price and shown above. The price depends on the number of tools, guardrails and tests, and whether deployment is included. Larger integrations are scoped individually; see the pricing page.
Can the MCP server be hosted for me?+
The Premium package includes deployment. Basic and Standard come with setup notes and a README so you can run it yourself, for example on a small VPS, a serverless function or a container host.
