The cache that proves it paid for itself.

tessera is a local-first, Postgres-backed MCP server for coding agents. Tickets, code, docs, and team memory — metered to the token, reported as a range, honest about the calls that lost.

Every figure reproducible with tessera report savings — including the bad ones. That's the pitch.

Stop paying twice for the same context

Ticket cache

Jira, Redmine, GitHub into one canonical model — incremental syncs, drafts only humans push.

Code atlas

Definitions, references, tests, impact as compact cards instead of directory dumps.

Team memory

Decisions with lifespans, supersede chains, compare-and-set state. Memory that grades itself.
