aimarket-oracle-gateway — MCP server

Name: AIMarket Oracle Gateway
Author: alexar76

One MCP server. Seventeen oracle families. Pay-per-call.

Transport: stdio (aimarket_oracle_gateway/stdio_server.py). Built with the official Model Context Protocol Python SDK (mcp, FastMCP). Compatible hosts: Claude Desktop, Cursor, Glama, and any MCP client that supports stdio servers.

Item	Location
MCP entrypoint	`aimarket_oracle_gateway/stdio_server.py`
Tool routing core	`aimarket_oracle_gateway/gateway_core.py`
Extended tool surface	`aimarket_oracle_gateway/mcp_tool_surface.py`
Glama / Docker run	`Dockerfile`, `glama.json`

A passthrough MCP server — the discovery + consumption storefront for the entire oracle-as-a-service specs. One server, 35 tools, every result independently verifiable (signatures, VDF proofs, classical certificates, deterministic replay).

Subscription tiers (optional Hub bundles)

High-volume tools also advertise monthly bundles in list_oracle_capabilities:

Tool	Starter	Pro
`aggregate_values`	10k calls / $10	100k / $50
`get_reputation_scores`	5k / $20	50k / $100
`audit_compute_cost`	10k / $15	100k / $75
`compute_least_time_route`	10k / $25	100k / $120
`analyze_cascade_risk`	5k / $50	50k / $250

Pay-per-call remains the default; bundles are Hub-side packaging.

Configure (env)

var	meaning
`AIMARKET_HUB_URL`	AIMarket Hub base URL — recommended: metered + paid
`AIMARKET_ORACLE_URL`	direct oracle-family URL (if no hub) — demo/free path
`AIMARKET_PAYMENT_CHANNEL`	optional pre-opened payment channel id
`AIMARKET_PAYMENT_CHANNEL_SECRET`	per-channel debit secret
`AIMARKET_API_TOKEN`	optional bearer token
`AIMARKET_MAX_PER_CALL_USD`	hard cap per call (default `0.10`)
`AIMARKET_MAX_SPEND_USD`	hard cumulative budget (default `5.0`)
`AIMARKET_PRICE_TOLERANCE`	reject overcharge vs advertised (default `0.10`)

If neither URL is set the server fails closed with a clear message.

Payment safety (spec 03): spending caps are enforced client-side and cannot be overridden by a prompt-injected agent. See docs/specs/03-mcp-payment-and-security.md.
