"An MCP that can programmatically interact with any online API" matching MCP servers:

Enables LLMs to interact with vehicle CAN bus and OBD-II data through a simulated ECU environment. Provides tools for reading frames, decoding messages via DBC files, monitoring signals, and querying automotive diagnostics without requiring physical hardware.

AI-powered FPGA power estimation assistant that wraps Xilinx PDM API as MCP services for natural language power modeling and analysis.

Controls a running KiCad 9+ instance via the official IPC API, enabling board edits, queries, and exports without reload.

Enables AI assistants to compile, upload, and monitor Arduino boards via natural language, with electrical safety checks and dependency management.

MCP server for Raspberry Pi peripheral bus access, enabling AI agents to interact with CAN, I2C, SPI, UART, and GPIO directly through natural language.

MCP server for Arduino IDE 2.0 sketches. It exposes a small REST API plus an MCP stdio bridge so agents can read and write the main .ino file, list sources, and optionally compile with arduino-cli.

Enables AI assistants to automate CODESYS V3 PLC development, including project editing, builds, library and alarm management, online variable read/write/force operations, and CODESYS documentation search via MCP.

An MCP server that enables MCP clients to interact with ROS 2 systems, providing runtime access and safe project creation and modification.

Bridges a RisalDash ESP32/ESP8266 device to MCP — every dashboard widget becomes a get_/set_ tool, so an agent can read sensors and toggle relays.

Enables agents to query LAVA board farms, submit and manage test jobs, and open interactive board sessions via the LAVA REST API.

An MCP server for EMBA firmware analysis that exposes structured security findings and tools to LLMs. It enables users to programmatically query, reason over, and correlate firmware analysis results such as kernel details, SBOMs, and attack paths.

An MCP server that lets AI agents interact with Siemens TIA Portal via its Openness API.

MCP server that exposes immutable CAN signal and MISRA reference facts as read-only resources and provides a human-gated defect filing tool with tamper-evident audit logging.

Enables pushing text from an AI conversation to a low-cost BLE e-ink shelf label via an MCP tool, with rich-text markup, card-style letter layouts, and real-time SSE delivery to a phone control page. Also lets clients check current screen content, update time, push history, and whether a phone is online.

Provides AI agents with instant, structured access to electronic component datasheets, pinouts, and electrical specifications without requiring PDF uploads. It enables seamless part searching, design validation, and side-by-side component comparisons across major hardware providers.

An MCP server that lets an AI assistant manage your Keenetic router in plain language — list connected devices, pin static DHCP leases, rename devices, check WAN status, and reboot.

MCP server that translates natural language commands into SCARA robot arm control instructions, featuring simulation mode, safety validation, and multiple transport modes (STDIO/HTTP/OAuth).

An MCP server for source-grounded, page-cited evidence retrieval tailored for embedded and firmware development, returning verbatim snippets with exact citations or 'no match' to prevent fabrications.

Enables AI agents to control serial port devices (modems, instruments, embedded boards) via MCP tools for listing ports, connecting, and sending/receiving commands.

MCP server that lets LLMs talk to serial devices: microcontrollers, routers, modems, embedded Linux, anything with a UART.
