Best Apache NiFi MCP Servers
Apache NiFi is a dataflow system designed to automate the flow of data between systems.
Why this server?
Allows interaction with Apache NiFi 2.x through its REST API. Supports discovering processor types, building and wiring process groups, managing processors and controller services, handling parameter contexts, starting flows, inspecting queues and bulletins, and importing/exporting flows.
AlicenseBqualityBmaintenanceEnables MCP clients to discover processor and controller service types, build and wire Apache NiFi 2.x process groups, schedule them, and debug queues and bulletins through the NiFi REST API. Supports flow spec application, automatic canvas layout, parameter contexts, and an optional read-only mode that blocks all writes.35Apache 2.0Why this server?
Provides tools for interacting with the Apache NiFi REST API, enabling management of process groups, processors, connections, queues, controller services, parameters, provenance, and version control in a NiFi instance.
FlicenseBqualityCmaintenanceEnables AI agents to manage and interact with Apache NiFi through its REST API, covering process groups, processors, connections, queues, provenance, and version control via natural language tool calls.28-Why this server?
Provides tools for building, testing, debugging, and shipping Apache NiFi 2.x data flows. The server can create flows from declarative specs, validate processor schemas, inject test FlowFiles, run flow tests and golden replays, diagnose processor groups, manage registry versions, and lay out NiFi canvases.
AlicenseNot gradedqualityAmaintenanceEnables an AI assistant to turn a plain-language description into a working Apache NiFi 2.x flow, validate and layout the canvas, run test data, golden-file replays and diagnostics, and commit only verified versions to the NiFi Registry. It exposes 44 read-or-write tools for exploring, building, testing, debugging and releasing flows, staying read-only unless writes are explicitly enabled.1Elastic 2.0Why this server?
Provides read-only tools for inspecting Apache NiFi flows: health checks (back-pressured queues, invalid or stopped processors, down controller services, error bulletins), flow tree/search, process groups, components, processor state, controller services, parameters, queue contents, individual FlowFiles, and provenance events.
AlicenseNot gradedqualityAmaintenanceThis read-only MCP server lets AI assistants inspect Apache NiFi, ClickHouse, and Kafka across multiple environments through natural language. It provides health checks, flow and message searches, querying and metadata tools while enforcing OIDC or proxy authentication, per-user auditing, secret masking, and two-lock read-only safeguards.45 PyPIApache 2.0Why this server?
Provides read-only investigation of Apache NiFi flows, including scoped flow descriptions, health and queue status, provenance tracing, unmatched route inspection, snapshot comparison, and local reviewable flow drafts. It does not modify NiFi.
