Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

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 →
call_command Call Command ~178
Run a SiLA command. This may physically act on the device (move, dispense, heat, shake, open doors): tell the user what will happen first. Parameters are validated against the Feature Definition before anything is sent, and the command must be in the allow-list if one is set. Unobservable commands return their responses; observable ones return an `execution_id`.

What is the SiLA 2 Bridge MCP server?
SiLA 2 Bridge is an MCP server listed in the public MCP registry as io.github.K-Dense-AI/labmcp-sila2. MCP bridge to any SiLA 2 server (lab-automation standard). This page covers its PyPI package (labmcp-sila2).
Is the SiLA 2 Bridge MCP server safe to use?
SiLA 2 Bridge scores 68 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 SiLA 2 Bridge MCP server expose?
SiLA 2 Bridge exposes 13 tools: get_connection_info, get_command_log, reconnect, discover_servers, get_server_info, and 8 more. Their descriptions and schemas cost roughly 957 tokens of context every time the server is loaded.
Is the SiLA 2 Bridge MCP server still maintained?
SiLA 2 Bridge 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 SiLA 2 Bridge MCP server under?
SiLA 2 Bridge 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.
