What changed in Lumin

Lumin moves to two plans. Free is $0 and includes 300 tool calls a month per account (was 100 a day). Pay as you go adds prepaid call packs on top, no subscription.

The four tiers (free, starter, pro, enterprise) are retired. All 158 tools are on every plan, nothing is gated, and one call is one call.

Prepaid call packs announced: $10 for 5,000 calls, $25 for 15,000, $50 for 35,000, $100 for 100,000. Pack calls never expire. Checkout is not live yet; if you need more calls now, write to contact@lumin.guru.

Failed calls no longer count against the meter. Only successfully executed tool calls consume allowance, and protocol traffic (initialize, tools/list, notifications) is never counted or blocked.

The allowance refreshes on the 1st of each month, UTC, per credential: per signed-in account on OAuth, per key on API key auth. When it runs out, tools/call returns HTTP 429 with a JSON-RPC error (code -32000) carrying retryAfterSeconds, limit, remaining, and resetAt. Every MCP response now carries X-RateLimit-Limit and X-RateLimit-Remaining.

Custom limits for bigger integrations are available by arrangement, write to contact@lumin.guru.

Breaking: the credential-free endpoint is gone. Every request now carries an API key or a signed-in account.

Sign in is an email address and a six digit code. No password, no provider to choose.

What to do.

One endpoint, mcp.lumin.guru/mcp, serves both auth modes. The old OAuth path still resolves but is no longer documented.

Architecture enhancement. Authentication and data storage moved to a new architecture. No changes needed to working integrations.

Tool counts across the site and docs now match the server: 158 tools, 8 of them composite workflows.

Lumin can now answer event questions with a cross-school consensus, like 'all four schools agree' or 'KP yes, KCIL mixed'. New questions you can ask: how Khullar's weighted formula scores your chart for an event, whether your birth time passes Andrew Dutta's Rule of Origin rectification check, and how a twin's chart diverges from yours on a single 0-100 scale.

14 new tools, grouped by theme.

14 new engine endpoints back the tools. Khullar ayanamsa added to validators across the chart pipeline, so any existing tool can now be called with ayanamsa set to khullar.

Multi-system verdict tool is the headline addition. Pass a chart and an event, get back four normalized verdicts and a consensus level (UNANIMOUS, STRONG, MIXED, or SPLIT). Use it as a defensible cross-school headline instead of any single school alone.

All four schools agree only when the chart is unambiguous. Most charts return MIXED on something, which is itself a signal. The per-school breakdown shows which lineage's logic disagrees and why.

Ask Lumin to read the weather of a season, a two-week window, a monsoon onset, or a single moment, for any place on Earth. Every reading shows its working, the same as any other Lumin answer.

4 new astrometeorology tools. Unlike every tool before them, these take a location and date, not birth data, so no birth profile is needed.

The method reads three traditions together: Western astrometeorology supplies the cardinal ingress and lunation charts, the Vedic Sapta Nadi Chakra and Ardra Pravesha supply the rainfall instruments, and the KP 4th-cusp sub-lord supplies a single traceable verdict point.

4 new engine endpoints back the tools. The computation engine can now cast a chart for any place and moment, not only for a birth.

Every astrometeorology response carries a plain-language disclaimer. This is the astrological tradition's seasonal read, not a meteorological forecast, and not a substitute for an official weather service.

62 new tools, grouped by lineage and domain.

8 composite workflow tools bundle 5-15 sub-calls into atomic recipes, one round-trip per reading.

Expert reading patterns from senior practitioners (KSK, K.N. Rao, Sanjay Rath) baked into the orchestration prompt.

Each non-KP tool carries a lineage tag like [Vedic Parashari], [Jaimini], or [Tajik] in its description, so B2B integrators can filter by tradition.

All tool descriptions standardized to Anthropic MCP best practices: inline term definitions, return-shape documentation, cross-references between related tools.

New question types you can now ask Lumin, grouped by domain.

Engine endpoints: 50 to 78. MCP tools: 49 to 77. Auto-generated per-tool reference pages at /build/reference/tools/<slug>.

Engine quality and orthodoxy improvements across longevity, surgery, hour-and-minute timing, horary, dasha, combustion, and rectification paths. Verdicts and confidence levels can shift on the same chart input. This is intentional.

Tool descriptions tightened across the 27 new tools for narrower intent matching by the LLM.

Event timing and horary now run on stricter v2 logic by default. Predictions are more conservative but stand up to verification.

v2 methodology tools active by default: ›find_event_timing_v2 (3-lock dasha + RP filtering + transit hierarchy) and ›get_horary_chart_v2 (Moon connectivity validation).

New methodology helpers: ›get_fruitful_significators and ›get_transit_timing_hierarchy.

14 advanced technique tools added: CSL convergence, retrograde, dasha, transit, RP, horary, medical, financial, foreign settlement, marriage, career, legal, muhurta, and rectification.

Deprecated v1 finders removed from the public surface. Callers receive a clear error pointing to the v2 replacements.

All 49 engine-backed tools available on the public MCP endpoints (50 with the ›set_birth_profile meta-tool). OAuth 2.1 endpoints live at mcp.lumin.guru/mcp/auth. Anonymous tier set to 50 calls per day per IP.

Lumin is now publicly available. Connect from Claude or any MCP-compatible client. 50 free calls per day per IP, no account required.

Initial public release of the Lumin MCP server at mcp.lumin.guru. 33 KP tools exposed (including original v1 finders, replaced in v2).

Anonymous and API key auth modes. OAuth not yet available. Streamable HTTP transport, stateless per-request server lifecycle.
