Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| PLR_MCP_BACKEND | No | Liquid handling backend (chatterbox, star, ot2, evo) | chatterbox |
| PLR_MCP_OT2_HOST | No | IP address of the OT-2 robot (required when backend is ot2) |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| setup_deckA | Initialize the liquid handler and place labware. Call this before any liquid handling tool. backend: 'chatterbox' (simulation, no hardware), 'star' (Hamilton STAR), 'ot2' (Opentrons OT-2, needs host), or 'evo' (Tecan Freedom EVO). Defaults to the server's configured backend. For chatterbox and star a 1000 uL tip rack and a Corning 96-well plate are auto-loaded onto a STARLet deck. host: OT-2 robot IP address (only used when backend='ot2'). |
| deck_stateA | List the resources currently assigned to the deck and the run mode. |
| pick_up_tipsA | Pick up tips from the tip rack. |
| drop_tipsC | Return tips to the tip rack at the given range. |
| aspirateB | Aspirate |
| dispenseB | Dispense |
| transferA | Transfer |
| read_plateA | Read the plate in the reader. |
| thermocyclerA | Control the thermocycler. |
| heater_shakerA | Control the heater-shaker. |

Scored across 10 tools
Each tool targets a distinct operation (aspirate, dispense, transfer, tip handling, deck setup, heater-shaker, thermocycler, plate reader) with no overlaps. Actions are clearly separated.
All tool names use lower_snake_case with clear verb_noun patterns (e.g., pick_up_tips, drop_tips, read_plate). Naming is uniform and predictable.
10 tools cover core liquid handling and lab equipment operations without being excessive. Each tool earns its place for a robotics lab server.
Covers setup, liquid transfers, tip management, temperature control, and reading. Minor gaps like explicit mixing or pause/move commands exist, but transfer can handle mixing.
