The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

What is the Ocean Insight Spectrometer MCP server?
Ocean Insight Spectrometer is an MCP server listed in the public MCP registry as io.github.K-Dense-AI/labmcp-ocean-spectrometer. MCP server for Ocean Insight / Ocean Optics spectrometers (python-seabreeze). This page covers its PyPI package (labmcp-ocean-spectrometer).
Is the Ocean Insight Spectrometer MCP server safe to use?
Ocean Insight Spectrometer scores 83 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 30 September 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Ocean Insight Spectrometer MCP server expose?
Ocean Insight Spectrometer exposes 16 tools: get_connection_info, get_command_log, reconnect, list_spectrometers, get_device_info, and 11 more. Their descriptions and schemas cost roughly 1,658 tokens of context every time the server is loaded.
Is the Ocean Insight Spectrometer MCP server still maintained?
Ocean Insight Spectrometer is still listed as active in the MCP registry. We last reached this channel on 30 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Ocean Insight Spectrometer MCP server under?
Ocean Insight Spectrometer declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
