Build your own Connector.MCP Fusion Framework

Our SDK is open source and Apache 2.0 licensed. Write a server, test it locally, and ship it to the Vinkius catalog. We handle hosting and distribution.

Ask AI about Open Source

From prompt to production

MCP Fusion isn't for humans. It's for AI agents.

Just tell your AI what you need. It writes the Connector. Run vurb deploy and it's live: hardened, governed, and battle-tested on the Vinkius.

"I need a Connector for our ERP. We use Prisma. Tools for inventory & suppliers. Redact sensitive data. Purchases need approval."

Schema-as-firewall. Undeclared fields never reach the LLM.

Schema-as-firewall. Undeclared database fields are physically stripped before reaching the LLM. New columns invisible until declared.

1,072 lines of implementation. AOT serializer compilation via fast-json-stringify. 6-phase pipeline: validate → truncate → redact → rules → ui → suggest. Config freezes after first .make().

Tools the AI cannot see, the AI cannot call.

Physically impossible for AI to call tools out of order. Unavailable tools vanish from the protocol.

XState v5 integration with lazy-loading. Physical removal from tools/list: not a validation guard, a protocol-level vanishing. Snapshot/restore for serverless. Clone isolation for concurrent requests.

Compiled PII redaction. Cryptographic lockfiles. GDPR from day one.

Compiled PII redaction at config-time. GDPR, LGPD, HIPAA ready. Zero overhead on the hot path.

SHA-256 behavioral fingerprint. mcpfusion.lock captures the behavioral contract of each tool. PRs show exactly what changed in the AI-facing surface. Git-diffable SOC 2 artifacts.

MCP Fusion isn't an evolution. It's an entirely new category.

It controls what AI sees. Locks down PII at compile time. Makes bad tool calls impossible. Secures agent connections with zero trust. Ships with crypto audit trails. AI-readable out of the box. Nothing else comes close.
