ClawRoute

Open-source LLM cost router · on npm Feb 2026
  • A local HTTP proxy that intercepts LLM requests, classifies task complexity with sub-5ms local heuristics, and routes simple work to cheap models and hard work to frontier models — 60–90% cost reduction, with automatic escalation on failure.
  • Works with any OpenAI-compatible client. Ships a real-time savings dashboard, per-request SQLite cost tracking, and a dry-run mode.

fhir-journey-mcp

MCP server over hospital FHIR data Oct 2026
  • A read-only MCP server that gives AI agents patient context from any FHIR R4 server: patient search, a merged journey timeline, appointments, open slots, and a worklist of discharged patients with no follow-up booked.
  • Retries with backoff, ID validation, paging that never sends credentials off-origin. 22 unit tests plus a live end-to-end check against the public HAPI FHIR server.

recon-trace

Bank statement vs Tally reconciliation Oct 2026
  • Matches an HDFC statement CSV against a Tally XML export by reference, then by amount and date. Amount mismatches are held for review and ambiguous pairs are listed rather than guessed; every result points back to its source row.
  • Integer-paise arithmetic, order-independent matching, and tie-out checks that fail the run if the totals don't add up. 37 tests.

tross-sdk

  • An unofficial TypeScript SDK for the Tross EHR and payer API. A crawler generated Zod schemas for all 119 operations across 11 integrations from the public docs; typed client with retries, timeouts and typed errors, and every operation exposed as an MCP tool.
