SPX dealer positioning from FirmTape, measured from the 0DTE tape rather than assumed from stale open interest. Free tools (no key): list_sessions, get_session, get_levels, get_level_history, get_gex_profile, search, fetch — 1,088+ finished SPX sessions, each with the zero-gamma flip, call/put walls, hold band and net-gamma percentile. Every number is verifiable against the free replay at https://firmtape.com/sessions. Deliberately no buy/sell signals: it is a measurement instrument. Sign in with a FirmTape account (OAuth) to unlock the Lab tier: lab_compile, lab_run, lab_state, lab_thread, lab_idea — compile a dealer-gamma rule, backtest it against the full archive with honest out-of-sample verdicts, and quant-optimize it from your AI assistant. FirmTape was previously named gex.live. Docs: https://firmtape.com/mcp

MCP readiness

B · 81/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here B, 82.9/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	10/10	initialize and tools/list both answered.
Live MCP endpoint	25/25	Endpoint answers the MCP initialize handshake (1162 ms).
Protocol revision	6/10	Speaks MCP 2025-06-18, 2 revision(s) behind 2026-07-28.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	30/30 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 14 tool(s) with descriptions.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	0/5	not seen in a source for over 30 days.
Auth declaration	2/5	Declares credential scheme: smithery_api_key.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (1162 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,039 reachable MCP servers in our daily snapshot (2026-11-12 06:46 UTC). Display only; it does not change search order.

Readiness: Higher than 52% of peers; This listing 81 · peer median 81
Latency: Faster than 50% of peers; This listing 328 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Verified identity −5 — Claim the listing and prove control of its domain.
Now: Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags −5 — Keep the listing current in the registry or source it comes from.
Now: not seen in a source for over 30 days.
Protocol revision −4 — Support the current protocol revision.
Now: Speaks MCP 2025-06-18, 2 revision(s) behind 2026-07-28.
