Connect Claude and ChatGPT to the systems your business runs.

What we build

• Custom Claude connectorsThe Claude directory covers the popular SaaS apps. Your ERP, your database, your internal API, and the spreadsheet that runs operations usually have no connector at all. We build one, host it, and roll it out to your Claude Team or Enterprise workspace.
• Done-for-you Claude connectorsMost teams do not want an MCP project. They want Claude to know their customers, orders, files, and numbers by next month. We take the whole job: scoping, build, hosting, security, rollout, and upkeep.
• Custom MCP serversOne well-built MCP server gives Claude, ChatGPT, Cursor, and your own agents the same governed access to your data and actions. We design it around your workflows, secure it like any other production API, and run it.
• Custom ChatGPT pluginsOpenAI now lets companies add their own plugins to ChatGPT, built on MCP. We build the plugin for your internal systems, set it up for your workspace admins, and make sure each person only reaches what they already can.

MCP servers we have built

Built and tested by Prestyj. Client names withheld.

• Portfolio data connector for an investment firm

  Yardi via Power BI · Monday.com · SharePoint

  A remote, read-only MCP server that answers portfolio questions from evidence-backed records across three source systems.

  • Streamable HTTP endpoint with OAuth protected-resource metadata and a delegated, API-scoped token per user
  • Denied data is reported as withheld, never guessed or filled from another source
  • Conflicting sources are shown side by side with their evidence instead of being averaged
  • Server instructions kept under the 2,048 character limit Claude Code applies, enforced by a test

• Connect-once business memory over MCP

  Monday.com · Yardi · SharePoint · Postgres

  Syncs a company's apps into typed facts in Postgres once, then hands them to any AI client over MCP.

  • Six tools: schema, brief, read-only SQL with a five second cap, document search, open conflicts, and resolve conflict
  • When sources disagree, a person answers once and the answer becomes a rule
  • Works in Claude Desktop, Claude Code, and any other MCP host

• Governed context server for a research platform

  Versioned context API · Webhooks

  A stdio MCP server with 24 workflow-specific tools that never sees a database URL or tenant ID.

  • The API key resolves the tenant; caller-supplied tenant or access fields are rejected before execution
  • Every tool enforces a scope plus result, time, output-token, and cost ceilings
  • Read-only by default; writes need a separate switch, explicit confirmation, and an idempotency key
  • A tool-selection benchmark checks that the model picks the right tool for each question

• Multi-tenant MCP for isolated customer deployments

  Per-customer deployment · Per-customer database

  One codebase deployed separately for each customer, with an MCP endpoint whose tool catalog comes from that customer's configuration.

  • OAuth token introspection with a dedicated read scope
  • Per-token rate limits and bounded request sizes
  • No customer data or secrets in the shared code or deployment packs
