Deltasignal Atlas Codex Plugin MCP Server

DeltaSignal ATLAS-7 - SEC-Grounded Issuer Intelligence for Agents

Real-time financial signals, risk, fundamentals, and alpha for crypto-exposed public companies. Latest public checkpoint: June 20 grant-expiry and Natural Language grant-coverage rollout, with OpenAPI 48 paths, live pricing/field-contract discovery, free MCP initialize and tools/list discovery, x402 challenges for protected execution, grant-window expiry fields for active grants, and fresh 215-issuer ATLAS-7 audit status through the MCP audit tool.

Common workflows are exposed as composite MCP presets so agents can call one reliable tool instead of hand-orchestrating several low-level calls. The live Azure service also exposes an operator audit-status tool so agents can verify that the full 215-issuer regression run is healthy before relying on the surface.

Native MCP server plus x402 micropayments. First 5 calls are free where supported, then Base USDC through compatible x402 clients. No subscription required.

Agents discover, pay, and execute deterministic workflows through MCP tools, OpenAPI routes, and Arazzo scenario definitions.

Also available as a Glama Connector. Smithery remains available as an alternate connector path.

Coinbase x402 / Codex Marketplace Review Focus

Delta Signal ATLAS-7 should be reviewed as a Codex-ready, x402-payable financial evidence service, not as a generic chat plugin.

The public review surface is ATLAS-7 issuer intelligence:

• MCP discovery before paid execution.
• OpenAPI route contracts with reachable REST routes and 402 response behavior.
• Arazzo workflow metadata for bounded scenario planning.
• x402 challenge and retry behavior through Base USDC.
• Route-level pricing and payment metadata.
• Evidence-preserving JSON or Markdown outputs with source dates, caveats, quality flags, payload mode, route provenance, and non-advice boundaries.

Recommended reviewer path:

1. Install the Coinbase payments MCP and this Codex plugin.
2. Inspect MCP tools/list before any paid call.
3. Inspect https://api.aitrailblazer.net/openapi.json.
4. Probe GET https://api.aitrailblazer.net/v1/readiness.
5. Confirm that a plain unauthenticated paid route may return HTTP 402 Payment Required.
6. Retry through an x402-compatible client or an active grant context.
7. Inspect returned metadata before trusting rendered prose.

Marketplace reviewers should validate extensions.bazaar.routeTemplate=/v1/readiness, an output example, merchant resources, seller payTo, amount/network/asset metadata, and the absence of unsupported Agentic Market first-party verification claims.

TripCode / River subscriber research is visible in public MCP discovery, but execution is x402/grant-gated and evidence-dependent. Do not promise a successful TripCode/River answer unless the live tool call resolves the required River / issuer index blobs.

How Agents Know and Run Workflows

The public landing page includes the animated workflow runner. The same contract is machine-readable here:

flowchart LR
  Intent["User intent<br/>morning brief, RIOT report, daily evidence"]
  Discover["Discover<br/>MCP tools/list<br/>OpenAPI<br/>Arazzo<br/>x402 metadata"]
  Plan["Plan<br/>select Arazzo workflow"]
  Execute["Execute<br/>MCP composite<br/>or REST sequence"]
  Pay["Resolve payment<br/>402 challenge<br/>Coinbase x402 pay + retry"]
  Result["Result<br/>bounded JSON<br/>Markdown evidence"]

  Intent --> Discover --> Plan --> Execute --> Pay --> Result
  Plan --> W1["marketReadinessScan"]
  Plan --> W2["singleIssuerDiligence"]
  Plan --> W3["dailyMonitoringEvidenceDrilldown"]
  Plan --> W4["mcpCompositePresetSelection"]

Agents do not need a special Arazzo runner to use this today. MCP clients can read the scenario definitions, select one of the exposed MCP composite tools, or follow the OpenAPI route sequence step by step. Public clients use x402 when a route returns 402 Payment Required; internal keyed validation is first-party testing only.

Changelog Feed Maintenance

rss.xml and atom.xml are generated from the machine-readable JSON embedded in changelog-llm.html:

node scripts/generate-changelog-feeds.mjs

The Changelog Feeds GitHub Action runs on changelog pushes, daily schedule, and manual dispatch. It refreshes the feed files and commits them when they drift, while the discovery contract workflow fails if a pull request changes the changelog without regenerating the feeds.

Seven Agent Workflows

The workflow layer is published as Arazzo 1.0.1:

• YAML: arazzo/deltasignal-arazzo.yaml
• JSON: arazzo/deltasignal-arazzo.json
• Public handshake only: arazzo/publicMcpX402Handshake.arazzo.yaml

These workflows are scenario guidance for agents. They do not replace OpenAPI or MCP; they tell an agent which operations/tools to call for a user intent.

1. publicMcpX402Handshake

Public onboarding and payment check.

Flow:

1. Call POST /mcp with JSON-RPC tools/list.
2. Do not send an internal key.
3. Expect HTTP 200 with the public DeltaSignal tool inventory.
4. Call a real tool such as deltasignal_readiness through the x402-capable client.
5. Expect either an attached grant to allow execution or HTTP 402 Payment Required. Supported grant paths are identity headers (X-Codex-User, X-Codex-Session, X-User-ID) or the wallet grant-session flow for enrolled EVM wallets: GET /v1/grant/challenge, sign the returned message, POST /v1/grant/session, then attach X-DeltaSignal-Grant-Token. Active grant contexts may expose grant_expires_at / grant_expires_in_seconds for the grant window; challenge/session expires_at fields remain short TTLs.
6. If challenged, let the x402-capable client pay and retry the same tools/call request.

Use this to confirm public MCP discovery and paid tool execution before real use.

2. internalMcpToolSmoke

First-party internal no-payment smoke on the same MCP endpoint.

Flow:

1. Call POST /mcp tools/list with x-api-key or mcp-api-key.
2. Expect HTTP 200.
3. Confirm the tool inventory.
4. Call deltasignal_readiness.

This workflow is internal validation only. Public users should use x402.

3. atlas7AuditStatusCheck

Operator readiness check for the scheduled Azure-native regression audit.

Flow:

1. Call MCP tool deltasignal_atlas7_audit_status through the paid/grant/internal MCP flow, or call GET /v1/atlas7/audit/latest with an internal/pre-authorized key. The REST audit endpoint is not a plain unauthenticated public probe.
2. Confirm status=healthy, stale=false, issuer_count=215, failed_count=0, historical_failed_count=0, and composite_failed_count=0.
3. Preserve the artifact prefix and finished_at_utc when summarizing.

This workflow is an operational audit surface, not a paid issuer-analysis route.

4. marketReadinessScan

Broad market operating picture.

Flow:

1. GET /v1/readiness
2. GET /v1/risk-distribution
3. GET /v1/top-stressed?limit=10
4. GET /v1/alpha-opportunities?limit=10

Use this when a user asks what is happening across the crypto public issuer universe.

5. singleIssuerDiligence

Full ticker-level diligence.

Flow:

1. GET /v1/company-fundamentals/{ticker}
2. GET /v1/alpha-signals/{ticker}
3. GET /v1/covenant-stress/{ticker}
4. GET /v1/peer-ranking/{ticker}
5. Optional: GET /v1/atlas-history/{ticker}?limit=30

MCP equivalent: call deltasignal_company_report with { "ticker": "RIOT" }.

6. dailyMonitoringEvidenceDrilldown

Compact daily monitoring first, raw evidence only when requested.

Flow:

1. GET /v1/daily-changes/latest
2. Optional: GET /v1/daily-changes/evidence?ticker={ticker}&source_date={source_date}&limit=25

Use this when a user asks what changed today, then asks why a specific issuer moved.

7. mcpCompositePresetSelection

Preferred MCP composite tools for common user intents.

Agents should prefer these server-enforced composites for common scenarios instead of manually fanning out low-level tools.

8. tripCodeResearchContinuity

Article-to-evidence continuity for DeltaSignal subscribers.

Marketplace caveat: this workflow is discovery-gated. Do not claim it is public marketplace-ready unless the deployed MCP tools/list exposes the TripCode tools and the required River / issuer index blobs are available. If discovery does not expose these tools, use the supported ATLAS-7 issuer workflow instead.

Flow:

1. Read the ATLAS-7 TripCode: TF-SUB-... value from a DeltaSignal article subtitle.
2. Call MCP tool deltasignal_resolve_article_tripcode with that TripCode.
3. Use returned continuity.linked_xbrl_tripcodes, linked_ds_tripcodes, and river_tripcodes to load filing evidence, computed DeltaSignal signals, and issuer thesis River context.
4. If a draft article is being prepared before publication, call deltasignal_generate_article_tripcode with DeltaSignal research identity fields. Do not use a Substack post ID as canonical identity.
5. If the user asks for the full subscriber thesis map and prior article nodes are not already provided, call deltasignal_list_article_tripcodes with the current TripCode, TF-RIVER TripCode, or issuer symbol to discover prior TF-SUB nodes automatically.
6. Call deltasignal_resolve_river_tripcode when the user wants the full persistent River graph, or deltasignal_reverse_search_river when the user wants thesis-lineage reconstruction.
7. Call deltasignal_article_thesis_map with the current article TripCode and the discovered River/evidence continuity. Do not require the subscriber to paste old TripCodes by hand.
8. If the article names filing evidence only, call deltasignal_resolve_filing_tripcode, then deltasignal_compare_article_to_filing_evidence for a compact verification packet.

Use this when a subscriber asks Codex or Claude Code to turn a DeltaSignal article into a machine-readable thesis map.

Public subscriber access is through MCP/x402:

1. Discovery is free: plugin page, tools/list, OpenAPI, Arazzo, llms.txt, and .well-known/x402.
2. Public tools/call may require a grant, free-tier allowance, or x402 payment proof.
3. x402-compatible clients receive a 402 challenge, pay through Base USDC, then retry the same request.
4. Full paid article text and LLM-friendly Markdown are entitlement-gated. If access is not verified, tools should return metadata, permitted summaries, continuity links, and restricted or missing status rather than leaking paid content.
5. Internal authoring write tools are not exposed publicly.

• deltasignal_alpha_signals
• deltasignal_company_fundamentals
• deltasignal_risk_distribution
• deltasignal_daily_changes - compact Daily Monitoring; no raw tag arrays; typical public route price $0.03.

• deltasignal_atlas7_audit_status - operator health check for the Azure-native 215-issuer ATLAS-7 regression audit; reports freshness, artifact prefix, operation count, historical failures, composite failures, and health state. This is a readiness/audit surface, not an issuer-analysis route.

All tools are read-only, schema-validated, and bounded for agent use.

TripCode Resolver Pricing

TripCode tools are MCP-first research-continuity utilities. They are priced to make subscriber article resolution cheap while keeping higher-value synthesis separate.

Public marketplace caveat: TripCode / River tools are discoverable in public MCP, but execution is x402/grant-gated and depends on deployed River / issuer index blobs. The strongest Coinbase / Codex marketplace path today remains ATLAS-7 x402 issuer intelligence: readiness, Morning Brief, Company Report, Pressure Board, Alpha Sweep, Quick Ticker Check, and issuer drilldowns.

Natural Language Briefs

Raw and composite routes return structured evidence. Natural Language routes compile that evidence into validated Markdown while preserving source dates, caveats, quality flags, evidence hashes, and non-advice disclaimers.

Current public routes:

• top_stressed_natural - live, $0.95, evidence-preserving Markdown brief for highest-stress issuers.
• morning_brief_natural - live, $0.95, backend-composed Natural Language Morning Brief.

Planned routes:

• covenant_stress_natural - $1.20

Access Model

• Public MCP endpoint: https://api.aitrailblazer.net/mcp
• Public OpenAPI: https://api.aitrailblazer.net/openapi.json
• Public x402 discovery: https://api.aitrailblazer.net/.well-known/x402
• Base x402 routes: https://api.aitrailblazer.net/v1/*
• Payment rail: Base USDC through x402-capable clients
• Seller payTo: 0x6D91ADF2c545047cbbC5b37a5f457cce081B48d3

First calls are free where a grant is configured or a free-tier policy applies. Supported grant paths are identity headers (X-Codex-User, X-Codex-Session, X-User-ID) or the wallet grant-session flow for enrolled EVM wallets: GET /v1/grant/challenge, sign the returned message, POST /v1/grant/session, then attach X-DeltaSignal-Grant-Token. Raw unsigned wallet headers are not a grant identity. After the free tier, compatible clients receive x402 payment requirements. If payment tooling is unavailable, inspect the route and expected cost, then retry through a Coinbase/x402-capable client.

Public x402 Probe

Before paid use, inspect the payment contract. A plain unauthenticated request may return HTTP 402; a compatible client with a configured identity grant or signed wallet grant may execute under that grant:

GET https://api.aitrailblazer.net/v1/readiness

Expected public behavior:

• HTTP 402 Payment Required
• x402Version=2
• network=eip155:8453
• Base USDC settlement
• seller payTo=0x6D91ADF2c545047cbbC5b37a5f457cce081B48d3
• Bazaar discovery metadata for the route

Do not claim Agentic Market first-party verification until the Agentic Market UI or Coinbase/Agentic Market team confirms the branded DeltaSignal ATLAS-7 listing.

Daily Monitoring, Evidence, and Export Packaging

DeltaSignal daily activity is split into separate products:

• Morning Brief answers "give me the daily picture" with one backend-composed scan across readiness, latest meaningful deltas, risk distribution, top stressed issuers, and alpha opportunities.
• Finished Morning Brief PDF uses StrategiX Visual MCP to package DeltaSignal evidence into a polished, branded, auditable PDF. Recommended workflow: strategix_delta_brief_pdf_full at $4.50 per market day.
• Monthly PDF Subscription is $79 for 22 daily briefs with auto-delivery and archive access.
• Heavy / Multi-Issuer Deep Brief is $9.00 when the finished PDF includes extra issuer drilldowns.
• Daily Monitoring answers "what changed today?" through compact MCP and REST responses with freshness, changed-company rows, source dates, and evidence references.
• Evidence Drilldown answers "show me why this issuer moved" through deltasignal_daily_change_evidence or GET /v1/daily-changes/evidence.
• Bulk Export is reserved for future artifact-backed full daily evidence packs; full exports should be saved as durable files, not pasted into chat context.

Public REST and payment surfaces:

• GET /v1/daily-changes/latest or GET /mpp/v1/daily-changes/latest - compact monitoring.
• GET /v1/daily-changes/evidence or GET /mpp/v1/daily-changes/evidence - issuer evidence drilldown.
• GET /v1/atlas7/audit/latest - authenticated operator REST status for the latest 215-issuer Azure regression audit. Public agents should prefer MCP deltasignal_atlas7_audit_status through the paid/grant/internal MCP flow.
• Future bulk evidence export proposal: small pack $0.15, standard pack $0.30, full daily export $0.75-$1.50.

Development Modes

• Local: DELTASIGNAL_PAYMENT_MODE=local
• Live production: DELTASIGNAL_PAYMENT_MODE=live
• Internal smoke: DELTASIGNAL_PAYMENT_MODE=internal with a pre-authorized key

Internal mode is for first-party validation only. Public users should use x402.
