# Mq Bridge App > Bridge between multiple MQ message queues and streams like nats or kafka - **Type:** MCP server - **Install:** `agentstack add mcp-marcomq-mq-bridge-app` - **Verified:** Yes β€” security-reviewed for prompt injection and unsafe behavior - **Seller:** [marcomq](https://agentstack.voostack.com/s/marcomq) - **Installs:** 0 - **Category:** [Databases](https://agentstack.voostack.com/c/databases) - **Latest version:** 0.1.0 - **License:** MIT - **Upstream author:** [marcomq](https://github.com/marcomq) - **Source:** https://github.com/marcomq/mq-bridge-app - **Website:** https://marcomq.github.io/mq-bridge-app/ ## Install ```sh agentstack add mcp-marcomq-mq-bridge-app ``` Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent. ## About # mq-bridge-app [](LICENSE) [](https://marcomq.github.io/mq-bridge-app/) crossing streams `mq-bridge-app` is a **fast, single-command ETL and data-movement tool** built in Rust β€” and, on top of the same engine, a multi-protocol bridge and traffic workbench for messaging. It ships in **three forms that share one engine and one config format**: a **desktop app** (visual workbench), a **CLI / server** (headless bridge and one-line `copy`), and a **library** (embed the engine in Rust, Python, or Node.js). Design a route once, run it anywhere β€” no rewrite in between. Supported integration types include **Kafka**, **RabbitMQ (AMQP)**, **NATS**, **AWS SQS**, **MQTT**, **IBM MQ** (optional), **HTTP**, **gRPC**, **ZeroMQ**, **MongoDB**, **sqlx (MySQL, MariaDB, PostgreSQL)**, and filesystem endpoints. > πŸ“– **All documentation lives in the [documentation book](https://marcomq.github.io/mq-bridge-app/)** β€” installation, quick start, tutorials, cookbook, connector reference, CLI, MCP, and performance tuning. This README is only a short overview; the book is the single source of truth. ## A quick taste At its core is a zero-config `copy` command that moves data between databases, queues, and files in a single line of bash β€” no YAML, no pipeline definition, no code: ```bash mq-bridge-app copy \ --from 'postgres://user:pass@localhost/db?table=src&sslmode=disable' \ --to 'file://out.jsonl?format=raw' \ --drain ``` The **scheme selects the endpoint** and **query parameters configure it**, so any sourceβ†’sink pair (Postgres, MySQL, MariaDB, SQLite, NATS, Redis, MongoDB, files, …) is just one URL each. And it's quick: in our benchmarks a 1,000,000-row Postgres β†’ JSONL job sustained **266,951 rows/s** at **~20 MiB peak RSS** β€” about **17x faster** and ~30x leaner than Meltano on the same machine. β†’ [Quick start](https://marcomq.github.io/mq-bridge-app/quick-start.html) Β· [Connectors](https://marcomq.github.io/mq-bridge-app/connectors/index.html) Β· [Performance tuning](https://marcomq.github.io/mq-bridge-app/operations/tuning.html) ## The three ways to run it Test connections and dial in a route in the Postman-inspired UI, export the JSON/YAML, then run that config as a service or from library code. One engine, one config format. | Form | What it is | Quick install | | --- | --- | --- | | **Desktop app (UI)** | The visual workbench β€” build/test routes, run request/response traffic, inspect message history | `brew install --cask marcomq/tap/mq-bridge` | | **CLI / server** | Headless binary: a one-line `copy`, a drain-then-exit batch job, or a long-lived bridge (also serves the same UI in a browser) | `brew install marcomq/tap/mq-bridge-app` | | **Library** | The engine embedded in your own code β€” native **Rust**, **Python**, or **Node.js** bindings | `cargo add` / `pip` / `npm` | **Learn each form in the book:** [the three ways to run it](https://marcomq.github.io/mq-bridge-app/getting-started/run-forms.html) Β· [the desktop / web UI](https://marcomq.github.io/mq-bridge-app/getting-started/desktop-ui.html) Β· [CLI commands](https://marcomq.github.io/mq-bridge-app/reference/cli.html) Β· [MCP server](https://marcomq.github.io/mq-bridge-app/MCP.html) Β· [library bindings](https://marcomq.github.io/mq-bridge-app/reference/bindings.html). ## Install `brew` is the quickest path on **macOS and Linux**: ```bash brew install marcomq/tap/mq-bridge-app # CLI / server brew install --cask marcomq/tap/mq-bridge # desktop app ``` On **Windows**, install the CLI with `cargo binstall mq-bridge-app`, or download the desktop installer / CLI from the [Releases page](https://github.com/marcomq/mq-bridge-app/releases). Also available via `cargo install mq-bridge-app` (from source) and the Docker image `ghcr.io/marcomq/mq-bridge-app:latest`. β†’ Every install method and platform (including the IBM MQ build and Docker) is in the **[Install guide](https://marcomq.github.io/mq-bridge-app/INSTALL.html)**; to compile from source see [Building](https://marcomq.github.io/mq-bridge-app/BUILD.html). ## Use it from an AI agent The same binary is an MCP server, so an agent can move data without the rows passing through its context: ```bash mq-bridge-app mcp install # register with Claude Code / Claude Desktop / Cursor ``` - MCP Registry name: `mcp-name: io.github.marcomq/mq-bridge-app` β†’ Tools, transports, and the token-cost measurement: **[MCP server](https://marcomq.github.io/mq-bridge-app/MCP.html)**. ## Features - **Multi-protocol bridging** β€” Kafka, IBM MQ, NATS, AMQP (RabbitMQ), MQTT, AWS SQS, gRPC, ZeroMQ, MongoDB, sqlx (MySQL/MariaDB/PostgreSQL), HTTP, and files. Act as an HTTP server *and* client, with full request-response support. - **Middleware chains** β€” retries, dead-letter queues, deduplication, rate limiting, buffering, transforms, weak-join correlation, and more, wrapping any endpoint. - **Built-in web UI** β€” Svelte-based management for publishers, consumers, routes, runtime status, presets, and imports; the same UI the CLI serves in a browser. - **Observability** β€” structured JSON logging and a Prometheus metrics endpoint. - **Flexible configuration** β€” hierarchical files (YAML/JSON/TOML) plus environment variables, suited to Container/Kubernetes. - **Security & storage** β€” config security modes (plain / extracted secrets / encrypted config / persistent encrypted history), encryption at rest, and local-first operation. - **High performance** β€” Rust + Tokio: low latency, high concurrency, small memory footprint. ## Why not just an API client? `mq-bridge-app`'s UI overlaps with API clients like Postman, Bruno, Insomnia, and Hoppscotch, but its center of gravity is different: message bridging, runtime operation, and long-lived route management rather than just request composition. Exact feature sets vary by product and edition; this captures the difference in emphasis. | Capability | mq-bridge | Postman | Bruno | Insomnia | Hoppscotch | | --- | --- | --- | --- | --- | --- | | Basic HTTP/API requests | βœ“ | βœ“ | βœ“ | βœ“ | βœ“ | | Scripting | β€” | βœ“ | βœ“ | βœ“ | βœ“ | | Cookie jar | Not yet | βœ“ | βœ“ | βœ“ | ~ | | Multipart forms | β€” | βœ“ | βœ“ | βœ“ | βœ“ | | Hex-level payload debugging | βœ“ | β€” | β€” | β€” | β€” | | Broker pub/sub workflow | βœ“ | MQTT | β€” | β€” | MQTT | | Long-lived consumers/routes | βœ“ | β€” | β€” | β€” | β€” | | Bridge traffic between protocols | βœ“ | β€” | β€” | β€” | β€” | | Replay messages | βœ“ | ~ | β€” | β€” | ~ | | Local-first workspace | βœ“ | ~ | βœ“ | βœ“ | ~ | | Git-friendly config | βœ“ | ~ | βœ“ | βœ“ | ~ | | Cloud sync by default | β€” | βœ“ | β€” | Optional | Optional | | AI / agent features | β€” | βœ“ | β€” | ~ | ~ | | Encrypted config | βœ“ | ~ | ~ | ~ | ~ | Use Postman/Bruno when your main job is crafting and sharing API requests; use `mq-bridge-app` when you need to connect systems, move messages between protocols, inspect live traffic, and manage bridge-style runtime configuration. ## Performance A CSV β†’ JSONL conversion hit **784,313 rows/s**; the same job **through an MCP tool call** ran at **735,330 rows/s** while costing an agent a *flat* ~370 tokens regardless of row count, because the rows never enter the model's context. β†’ Full numbers, methodology, and knobs: [Performance tuning](https://marcomq.github.io/mq-bridge-app/operations/tuning.html) and [`benches/etl/README.md`](benches/etl/README.md). ## How it's built `mq-bridge-app` uses the [`mq-bridge`](https://github.com/marcomq/mq-bridge) engine *on itself* β€” the management UI is served through the engine's own HTTP-request/response routing, and the UI form is generated from the Rust config schema (no hand-written form code). See [How the app is built](https://marcomq.github.io/mq-bridge-app/getting-started/app-architecture.html). ## Status Active development. Originally the reference implementation and testbed for the [`mq-bridge`](https://github.com/marcomq/mq-bridge) engine. The UI/Tauri layer is a working demo rather than a reference implementation β€” test before relying on it in production. ## License MIT β€” see [LICENSE](LICENSE). ## Source & license This open-source MCP server is cataloged on AgentStack and links to its original source β€” we do not rehost the code. - **Author:** [marcomq](https://github.com/marcomq) - **Source:** [marcomq/mq-bridge-app](https://github.com/marcomq/mq-bridge-app) - **License:** MIT - **Homepage:** https://marcomq.github.io/mq-bridge-app/ Install and usage instructions live in the source repository linked above. ## Pricing - **Free** β€” Free ## Security capabilities Automated source analysis of v0.1.0 β€” what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source β€” more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** β€” security scan: passed β€” Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/mcp-marcomq-mq-bridge-app - Seller: https://agentstack.voostack.com/s/marcomq - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack β€” the marketplace for AI agent skills and MCP servers.
