MCP Readers

Read-only FastMCP servers that let an agent inspect Postgres, MongoDB, Elasticsearch, S3 data and env files, with no ability to write.

About

Five servers sharing one read-only architecture: mcp-postgre-reader, mcp-mongo-reader, mcp-elastic-reader, mcp-s3-data-reader and mcp-env-reader. The env reader works by key name only, so no value ever reaches the model.
