tessera_list_workloadsLABSCO SUMMARY
Reads a cost picture and lets you act on one line of it.
The read tools answer the questions a cost-conscious engineer actually asks — what is drifting, what would switching save, did quality hold — and tessera_approve_recommendation is the single call that commits a change. The surface is deliberately kept small, which also means anything outside routing decisions still happens in the Tessera dashboard.
What it is
The agent-facing surface of Tessera, an LLM proxy that routes across providers to reduce API spend. Its tools read the state — workloads, savings, quality, the recommendation queue, the ledger — and one of them approves a recommendation.
What you get
- Your mapped workloads, each with its anchor cost and current model stack
- A savings report for a window: anchored spend against measured savings
- A quality snapshot, so a cheaper route can be judged on output and not price alone
- The queue of routing recommendations waiting on a decision
- Approval of a recommendation — the one call here that changes anything
- Ledger entries, kept append-only for audit
Requirements
TESSERA_API_KEY, issued at tesseraai.io/dev. The Free Sandbox tier issues one with no card and covers a monthly token allowance. Installs with npx @tessera-llm/mcp-server; Apache-2.0.
Setup effort
One command plus a key — npx @tessera-llm/mcp-server, then supply credentials
USE CASES
Finding out where your model spend is going
List the mapped workloads with their anchor costs, then read the savings report for the window you care about.
Deciding whether a cheaper model actually held up
Read the quality snapshot next to the pending recommendation, rather than judging the switch on price alone.
Approving a routing change without opening the dashboard
Pull the queue, pick the recommendation and approve it in the same conversation.
Showing what was changed and when
Read the append-only ledger entries, which is the record an auditor or a finance reviewer will ask for.
Reporting last month's savings to whoever signs off the bill
Take the anchored spend and measured savings for the period straight out of the savings report.
