## Model Context Protocol servers

- [mcp-data-platform](https://mcp-data-platform.txn2.com): An AI assistant can run SQL but doesn't know which columns contain PII, which tables were deprecated, or who owns the data. mcp-data-platform connects assistants to your data infrastructure and adds business context from your semantic layer (DataHub-anchored). Orchestrates mcp-s3, mcp-trino, and mcp-datahub behind a single endpoint with bidirectional cross-injection: Trino results carry DataHub metadata, S3 reads carry lineage. Includes a gateway toolkit that re-exposes any third-party MCP server through unified auth, persona, and audit pipelines, plus a DB-backed admin portal for encrypted credential management. Source: https://github.com/txn2/mcp-data-platform
- [mcp-s3](https://mcp-s3.txn2.com): Connects S3-compatible storage to MCP clients with read-only mode, size limits, prefix-based ACLs, and audit logging. Works with AWS S3, SeaweedFS, LocalStack, MinIO, or anything that speaks the S3 API. Multi-account from a single installation. Source: https://github.com/txn2/mcp-s3
- [mcp-trino](https://mcp-trino.txn2.com): Connects Trino to MCP clients with an optional semantic layer. Surfaces business descriptions, ownership, and data quality from metadata catalogs alongside query results, and marks sensitive columns so AI assistants know what not to read. Multi-cluster from one install. Source: https://github.com/txn2/mcp-trino
- [mcp-datahub](https://mcp-datahub.txn2.com): MCP server and Go library for DataHub. Search datasets, explore schemas, trace lineage, and read glossary terms, domains, and ownership. Ships as a standalone binary, a one-click Claude Desktop .mcpb bundle, or a composable library for building custom MCP servers. Source: https://github.com/txn2/mcp-datahub

## Utilities

- [kubefwd](https://kubefwd.com): Bulk port-forwards every service in a Kubernetes namespace, assigns each a unique 127.x.x.x loopback IP, and writes hostname entries into /etc/hosts. Existing in-cluster connection strings (http://api-gateway:8080, redis-cli -h cache, mysql -h database) work unchanged on a developer laptop. Interactive TUI with live traffic, pod logs, and auto-reconnect on pod restart. Invoked with `sudo -E kubefwd svc -n <namespace> --tui`. Source: https://github.com/txn2/kubefwd
- [txeh](https://txeh.txn2.com): Go library and CLI for /etc/hosts management. Originated as the substrate under kubefwd's hosts-file rewrites and grew into a standalone utility. Mutex-protected for concurrent use, supports IPv4 + IPv6, CIDR ranges, comment-based grouping
