MCPTap v2.5.0

[2.5.0]

Highlights

• Web-based request log viewer
• SQLite-backed log store

Added

• Web-based request log viewer — MCPTap now ships an embedded log viewer
  at /ui/logs (Vue 3 + Naive UI, dark theme). The viewer displays a
  virtual-scroll table of all proxied requests with columns for date, model,
  provider, input/output tokens, and cost. A time-range selector (15m – 1w)
  filters the view; cursor-based pagination with infinite scroll loads older
  entries automatically. Clicking any row opens a side drawer with full
  request metadata (session ID, HTTP status, stream flag, token breakdown,
  cost, path, duration) and pretty-printed JSON request/response bodies.
• SQLite-backed log store — proxied request metadata is persisted in a
  local SQLite database (WAL mode) with forward-only schema migrations.
  Configurable via MCP_TAP_LOG_DB (default: ~/.local/share/mcptap/logs.db).
  Records store timestamp, session ID, model, provider, input/output/total
  tokens, cost, HTTP status, full request/response bodies, request path,
  stream flag, and round-trip duration.
• Log API endpoints — two REST endpoints exposed by the proxy:
  GET /api/logs (paginated, time-range filtered, cursor-based) and
  GET /api/logs/{log_id} (full detail including request/response bodies).
• Usage extraction — extract_usage_details() parses input_tokens,
  output_tokens, total_tokens, and cost from upstream Responses API
  responses for storage in the log database.
• Log-store tests — 15 new tests in tests/test_log_store.py covering
  migrations, recording, paginated queries, detail lookup, and the
  record_from_response convenience wrapper.
• docs/FEATURES.md — new section 9 (UI interface) documenting the log
  viewer access URL, table columns, time-range presets, request detail
  drawer, backing API, and SQLite storage schema.
• docs/TROUBLESHOOTING.md — extracted from the README into a standalone
  troubleshooting guide.
• docs/DEVELOPMENT.md — new development documentation.

Changed

• README.md restructured — rewritten and reorganized for clearer
  installation, configuration, routing, model-instruction, and tool-call-hook
  guidance; redundant sections removed and RTK link corrected.

Fixed

• Request details drawer width — increased from 700px to 1200px for
  better visibility of detailed request data.
• Log-store test execution — tests/test_log_store.py re-enabled in the
  test runner (previously skipped); pytest import type-ignore added to
  tests/test_config_reloader.py to silence missing-stub noise.
