About Siglent Spd MCP

Siglent Spd MCP is an MCP server published by wannessels in the Developer Tools category: mCP server for Siglent SPD series programmable DC power supplies.

Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.

Install

From source
git clone https://github.com/wannessels/siglent-spd-mcp

This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

README

siglent-spd-mcp

MCP server for Siglent SPD Series Power Supplies (SPD3303X, SPD3303X-E, SPD1168X, etc.).

Exposes voltage/current control, measurement, monitoring, timer, and system configuration as Model Context Protocol tools over SCPI/TCP.

Installation

pip install siglent-spd-mcp

Configuration

The server connects to the power supply via TCP/SCPI. Set the host and port with environment variables:

Variable Default Description
SPD_HOST (required) IP address of the power supply
SPD_PORT 5025 SCPI TCP port

Permissions (default: readonly)

All channels default to read-only. Set to readwrite to allow control:

Variable Values Description
CH1_PERM readonly / readwrite Channel 1 write access
CH2_PERM readonly / readwrite Channel 2 write access
CH3_PERM readonly / readwrite Channel 3 write access
NETWORK_PERM readonly / readwrite Network config write access
MEMORY_PERM readonly / readwrite Save/recall write access

Safety limits (optional)

Set per-channel voltage and current limits to prevent accidental damage:

Variable Example Description
CH1_MAX_VOLTAGE 5.0 Max voltage for CH1 (V)
CH1_MAX_CURRENT 1.0 Max current for CH1 (A)
CH2_MAX_VOLTAGE 32.0 Max voltage for CH2 (V)
CH2_MAX_CURRENT 3.2 Max current for CH2 (A)

Usage

Claude Desktop / Claude Code

Add to your MCP client configuration:

Questions

About Siglent Spd MCP

How do I install Siglent Spd MCP?

No package has been published for this server, so install it from source: clone the repository and follow its README.

Is Siglent Spd MCP safe to use with an AI agent?

Its trust score is 55 out of 100 (fair). It passes 2 of the 3 static security checks run so far; the failures are listed above. It has no ConduID identity yet, so agent calls to it are not receipted.

Is Siglent Spd MCP still maintained?

The last commit was 7 months ago. That's long enough that you should check whether the maintainer is responding to issues before depending on it.
