MCP server (stdio, local) exposing 90 deterministic tools from Jarroba Tools, reusing the same code as the web app: read a CI log that does not fit in your context, audit tests, simulate make, run SQL against an ephemeral PostgreSQL, SPARQL, JTD diagrams

MCP server (stdio, local) that lets an AI read a log file it could never fit in its context: a 200 MB CI log. Detects the format, counts EVENTS (a 40-line stack trace is one), resolves root causes, groups lines into templates, answers when it started, and

MCP server (stdio, local) that audits tests instead of writing them. Told to "make the tests pass", an agent can widen a matcher, drop an assertion or skip a case - all cheaper than fixing the bug. These tools contradict the caller: what each test ACTUALL

MCP server (stdio, local) for maths a model gets wrong: arithmetic WITH UNITS and dimensional checking (adding metres to kilos is an error, not a silent number), equations and linear systems that say whether the answer is EXACT or approximate, multi-line

Run one prompt (a "task") over many files with the Anthropic API, directly or as a batch (Batch API, half price), with cost estimates, spending limits and output checks.
