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.

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.

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.

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 without payment.
5. Expect HTTP 402 Payment Required.
6. 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 GET /v1/atlas7/audit/latest with an internal/pre-authorized key, or call MCP tool deltasignal_atlas7_audit_status.
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.

Available MCP Tools

Composite presets:

• deltasignal_morning_brief
• deltasignal_company_report
• deltasignal_pressure_board
• deltasignal_alpha_sweep
• deltasignal_quick_ticker_check

Granular tools:

• deltasignal_readiness
• deltasignal_top_stressed
• deltasignal_covenant_stress
• deltasignal_peer_ranking
• 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_daily_change_evidence - explicit issuer proof drilldown; paginated raw Company Facts tags; 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.

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 5 calls are free where supported. 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 without spending:

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.
• 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 status for the latest 215-issuer Azure regression audit.
• 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.

Technical
