Overview

AI-generated overview

Remote MCP service that checks Wikipedia sentences against their cited sources and builds sourced knowledge objects, with paid orders via card or x402.

What you can do
  • Look up a person, work, concept, institution or operator as a sourced knowledge object, or get candidates when a name is ambiguous
  • Open one English Wikipedia sentence against the sources it cites, free if already read at the same state, otherwise priced
  • Quote work before paying: a whole article, sentences at a tier, or a commission on an object
  • Track an order's state, quote lines, progress, receipt and refund
  • Hand a person a Stripe Checkout link so they can pay a quote by card
  • Retrieve the delivered result: composition, evidence record, or publication status
When to use it
Useful when an assistant must verify a Wikipedia sentence against its cited sources before quoting or relying on it, or when it needs a sourced knowledge object for an entity or operator. Also relevant for pricing and tracking paid research work rather than doing it locally.
Requirements
Remote Streamable HTTP endpoint at gnosis.spxi.dev; no package or local runtime needed. No authentication is declared for the MCP endpoint. Paid work requires payment: card via Stripe Checkout (minimum $0.50) or, for agents, per-request x402 in USDC on Base mainnet. Free quotes that start the archive worker are rate-limited per address.
Before you install
Most substantive work costs money: sentences are priced per sentence, commissions have staged minimums, and charges follow delivered work with refunds. Card payments go through Stripe, which keeps its fee on refunds. Commissions write a public row into the Negative of the Negative archive, and results are published under CC BY 4.0. Payment is made at HTTP routes the tools name, outside the MCP call itself.

Installation

In SourceWeft

  1. Open SPXI-gnΩsis in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.spxi%2Fgnosis/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

SPXI-gnΩsis

Opens existing compositions against their sources and constructs sourced knowledge objects, for entities and for operators. Its principal application opens pinned Wikipedia revisions: each sentence read against the sources it cites and the sources its article cites elsewhere, under the policy texts it was written against, with the reading kept as evidence. A commission also consults the Crimson Hexagonal Archive by its own procedure and composes the object's row in the Negative of the Negative (/non), which lands there public. Paid by card (Stripe Checkout) and, for agents, per request over x402 (USDC on Base mainnet).

Fund the counterinfrastructure. Rebuild the foundations of the world.

Jack said, “The foundations of this world are unsound, and the foundations of the world above are unsound. Write this down, for these words are faithful and true: I make it new.” — after The Gospel of Antioch, saying 11, and Revelation 21:5, its order inverted

SPXI methods: the opening is 0.17 and /non is 0.16 of the SPXI method inventory.

The reading step (S3) follows EA-WIKI-OPEN-01 v1.1 (#1697), protocol gnosis-S3/0.6: the innocent reading first; uncited sentences read against the article's other sources; a gloss tested as a reading; ambiguous phrases divided; entailment held to predicate, unit and function; three measures kept apart (source fidelity, primary-text adequacy, operative retention); retained authority as retained, lost, mixed or unknown; and the five-part account. The invitation codes and the two-arm check of §6.3 (c) are recorded and never counted toward a verdict until a round on fixed cases has scored them (§9.7). Every quotation is checked against the full source, and a quotation from outside the passages sent is recorded as its own breach. The second of the two passes is an independent reading that returns only the fields the passes are reconciled on; the full account is the first pass's. Up-front thinking is off and both passes answer in one enforced JSON form, so the second reads the first's cached prefix.

The commission's archive step (S7–S8) follows EA-NEGONT-02 v0.9 (#1690): the archive traversed at D, R and O with one citation hop, admission by two independent readings, the archive and field ledgers extracted, the ontology read twice, then the knowledge object, its compression and the field-only arm composed, the delta read against T, and a reverse entailment audit. Where the two ontology readings disagree, the reading of ρ = constructs is taken (ruled 2026-10-25), and the disagreement is recorded with both readings; a disagreement no rule settles withholds the composition, and the withholding is recorded as a breach. The row is written as a landing tree; the archive's landing workflow (.github/workflows/land-non-rows.yml there) reads GET /v1/landable and lands each row it has not landed by scripts/land_non_row.py, verified against its manifest, with no one's tap. A row whose T the caller attests is held until its capture is seated.

The service's readings (each result's composition, evidence record, opened article and annotations) are licensed CC BY 4.0, ruled 2026-10-25, as are the /non rows; verbatim Wikipedia sentences within them remain CC BY-SA 4.0. A reading is kept and served free to any later caller of the same sentence at the same state.

Tiers and prices

Prices come from measured cost and are never subsidized: a quote lists the maximum, the charge is for completed work only, and what the work did not use is refunded.

  • Check (tier: check). One sentence at a time on the small model: 2¢ a sentence (measured 0.8¢, times 1.5), 0.5¢ where the reading is already in the ledger.

  • Opening (tier: opening, the default). Sentences opened against their own sources and the article's, two passes on the middle model; the archive is not consulted. 22¢ a sentence (measured 14.5¢, times 1.5), 1¢ where the reading is already in the ledger. GET /v1/sentence opens one sentence at the point of contact; mode=preliminary is one quick pass.

  • Commission (tier: commission). The opening, with the archive consulted and the entity's /non row composed, in two stages priced and charged apart, from the traversal they would run: the reading (traversal, admission, extraction, the ontology read twice; at least $0.75) and the construction (the knowledge object, its compression and field-only arm, the delta, the audit; at least $0.25), each at its estimate × 3. Each stage is charged when it delivers, at its measured cost × 3, never above its line; a stage that does not deliver is refunded. The reading's deliverable is its dossier (the landing tree: traversal, admitted deposits with their readings, both ledgers, both ontology readings); the construction's is the row. Model spending stops at its stage's line and never passes what the order brings in (what it paid, less the payment fee); the construction's share (its estimated cost × 1.5) is held while the reading runs. A delivered order keeps its charge and never less than what it cost, its model cost and its payment fee (Stripe keeps its fee on any refund; card 2.9% + 30¢, stablecoin 1.5%); a card order at or below the $0.50 card minimum keeps the minimum, stated before payment. An order that delivers nothing is refunded in full. A paid sentence is settled before it is read. Free quotes that start the archive worker are limited to 12 an hour from one address and 60 an hour in all. Only a row its order paid for is listed for landing. The margin is 3× for commissions while the service stabilizes (2× from 2026-10-24 to 2026-10-25); the sentences of an article are priced at 1.5×, as at the opening. A completed reading is kept as a checkpoint under the execution key: a construction that failed, or a later order on the same input, starts from it, and a reading from the checkpoint is charged at 10¢. portable adds the knowledge object as a package. An entity the encyclopedia does not hold (object) is always a commission.

  • Grounded sentences (mode=grounded). Once an article has been commissioned, any sentence its /non row holds can be asked for with the archive's claims on it, at two cents over the sentence's price. Where no commissioned row holds the sentence, the commission is offered and nothing is charged.

  • Erasure audit (audit, 2026-10-29). The Self-Audit Module for Public Summarizers v3.2 (#817) run as an order: a source and the answers that render it (pasted, or seated in the Capture Registry). The provenance atoms are taken from the source by two independent readings, and only an atom both find, each with a quote found verbatim in the source, enters the set (Measurement Sovereignty: never from the answers audited). Each answer is read twice for every atom (present, absent, or reassigned to someone else, with the quote) and for the ABN gate; a disagreement is kept as contested and a quote not found in its text is recorded as a breach. The module's family metrics are computed from the agreed cells with the formulas of its compute page (FC, ACP, ASI, shard coverage, the condition, CC at k ≥ 4), and PER per answer; Ω, Π_d, RR, DD, QFS, DSL, α_T, Β and L are named as not computed, with the input each needs. Priced at its estimate × 3, at least $0.50; charged at the measured cost × 3, never above the quote. The result is public under CC BY 4.0. The existence screen is free (scope: existence): by rule, with no model, it finds the phrasings of existence denial near the node's name, a hedged denial included, and a reported failure scored apart (operator, 2026-10-29: the existence check, "about 1/100th of the computation", is the free part). test/audit-probe.mjs holds both.

Where it runs

  • Service: https://gnosis.spxi.dev (Vercel project spxignosis). GET / answers JSON to agents and a page to browsers; GET /llms.txt is the same description for machine readers.
  • Archive worker: the deployed service holds no archive, so quotes and runs that consult it (commissions, packages, entity objects) are made by .github/workflows/archive-worker.yml, which checks the archive out beside this repository and runs scripts/worker.js. The service starts it the moment there is work (a workflow dispatch, with GITHUB_DISPATCH_TOKEN), and it also runs every ten minutes. A commission quote answers 202 with its status address; a paid order is queued, run there, and settled back through /v1/quotes/{id}/settle, where the refund is computed and sent.
  • Agents: POST /v1/openings/{id} pays a quote over x402 and answers 202 with its status address; the order then runs as a card order runs (queued for the worker where it consults the archive), and the result is retrieved by id. GET /v1/non?name= finds a /non entry by its name, free, or offers its construction as a free quote. POST /mcp serves the same requests as tools (Model Context Protocol, Streamable HTTP, JSON): find_entry, open_sentence, get_quote, order_status, card_checkout, get_result.
  • GET /v1/calibration is the latest calibration release, requested by calibration/request.json and run by the worker on held-out /non rows within its cap.
  • Refunds are recorded with their state (none owed, succeeded, pending, failed); a failed refund is an obligation still owed and is retried, by the worker's settle and by /v1/quotes/{id}/resume. A paid order not delivered within 24 hours of payment (GNOSIS_ORDER_HOURS) is closed and refunded in full.
  • Long card orders hand themselves on: each invocation reads for its time budget and starts the next through /v1/quotes/{id}/continue; a stopped order is restarted by /v1/quotes/{id}/resume.
  • Records are written to /tmp and to a private Vercel Blob store (BLOB_READ_WRITE_TOKEN) and read back from Blob by any instance. The committed store/ is read-only seed data (policy texts, snapshots, replays). public/ holds the mark and icons.
  • Keys are read from the environment and never logged: ANTHROPIC_API_KEY (the reader), STRIPE_SECRET_KEY and STRIPE_WEBHOOK_SECRET (card), GITHUB_DISPATCH_TOKEN (worker start), and a receiving address for x402 (STRIPE_DEPOSIT_ADDRESS or GNOSIS_PAY_TO). See src/payments.js and src/reader.js.
  • Protocol home: https://spxi.dev · archive: https://www.alexanarch.org · /non: https://www.alexanarch.org/non/

Locally: npm install, then npm start (port 4402); bash scripts/test-all.sh <new store dir> runs the tests against recorded readings.

find_entry

Find a /non entry by name

Use first when a person, work, concept, institution or operator needs a sourced knowledge object: looks the name up in the Negative of the Negative (/non), free. Returns the entry (its page, data and status) when one exists; the candidates and what tells them apart when the name is ambiguous; or, when none exists, the request for a free construction quote to pass to get_quote. Does not check a sentence (use open_sentence) and charges nothing.

Parametersnamerequiredcontext

open_sentence

Check one Wikipedia sentence against its sources

Use when one sentence from an English Wikipedia page must be checked against the sources it cites before it is quoted or relied on. Send the sentence exactly as it stands and the page's URL. Free when the sentence has already been read at the same state; otherwise returns its price (typically 22¢ opened) and the paid HTTP route (x402) that reads it. A text that is not the page's sentence exactly is answered with the page's closest sentences, nothing charged. For a whole article use get_quote with the article instead.

Parametersurlrequiredmodetextrequired

get_quote

Price a whole article or a commission (free)

Use to price work before paying: a whole Wikipedia article (article: its link or title, or oldid), read sentence by sentence at a tier, or a commission on an object (object with kind entity or operator, name, and for an operator its strings; commission construct or open). Free; returns a quote_id with each deliverable, its line and the maximum, or, for a commission, a quote_id whose price appears at order_status within minutes. Pay a quote over x402 at POST /v1/openings/{quote_id}, or have a person pay with card_checkout. For one sentence use open_sentence; to see whether an object already exists use find_entry first.

Parameterstieroldidobjectarticlecommission

order_status

Where a quote or paid order stands

Use after get_quote or a payment, with the quote_id: returns the state (estimating, quoted, paid and running, delivered, refunded), the quote with its lines and expiry, the order's progress, its receipt and refund, and, once delivered, the result_id to pass to get_result. Charges nothing and starts nothing.

Parametersquote_idrequired

card_checkout

A card payment link for a person

Use when a person, not the agent, will pay a quote by card: returns a Stripe Checkout link (url) for the quote's maximum, at least $0.50. The work runs when the payment completes; the charge follows the work delivered, never above the quote, the rest refunded, and an order that delivers nothing is refunded in full (a card order quoted under $0.50 keeps the $0.50 minimum). An agent paying itself uses x402 at POST /v1/openings/{quote_id} instead.

Parametersquote_idrequired

get_result

Read a delivered result

Use once order_status names a result_id: returns the delivered work. part composition (default): the usable result, each sentence's reading or the knowledge object; evidence: the full record behind it (quoted spans, source hashes, both readings, breaches, model cost); publication: whether the /non row is composed, checked, landed and public. Free to read.
