What is infrastructure?

Guidance for deploying FastMCP servers with Railway, Docker, Postgres, and Cloudflare R2.

Setting up Dockerfiles, Railway deployments, environment variables, Postgres, Cloudflare R2 storage, and Logfire monitoring.

It helps organize the container, deployment settings, environment variables, storage, database, and monitoring work needed to run a server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00032	$0.00612
Opus 5.5	$0.00013	$0.00245
Sonnet 5.5	$0.00006	$0.00122
Haiku 4.5	$0.00003	$0.00061

Security

Grade A, and why

infrastructure scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Infrastructure Expert

Skill for deployment, Docker, and cloud infrastructure.

When to Use

Invoke this skill when working on:

Railway deployment configuration
Dockerfile optimization
Environment variable management
Future database (Postgres) setup
Future blob storage (Cloudflare R2) setup

Current Stack

Deployment: Railway

Platform: Railway
Deployment: Dockerfile-based
Environment variables via Railway dashboard

Container: Docker

Base image: python:3.13-slim
Package manager: uv (fast Python package manager)
Entry point: FastMCP server

Observability: Logfire

Pydantic Logfire
Automatic OpenTelemetry instrumentation
Configure via LOGFIRE_TOKEN env var

Dockerfile Pattern

FROM python:3.13-slim

WORKDIR /app

# Install uv
COPY --from=ghcr.io/astral-sh/uv:latest /uv /usr/local/bin/uv

# Copy dependency files
COPY pyproject.toml uv.lock ./

# Install dependencies (cached layer)
RUN uv sync --frozen --no-dev

# Copy source code
COPY src/ ./src/

# Run server
CMD ["uv", "run", "python", "-m", "siigo_mcp.server"]

Environment Variables

Required

SIIGO_USERNAME: Siigo API username
SIIGO_ACCESS_KEY: Siigo API access key
SIIGO_PARTNER_ID: Partner identifier for API calls

Optional

LOGFIRE_TOKEN: Pydantic Logfire token for observability
LOG_LEVEL: Logging level (default: INFO)

Future Infrastructure

Database: PostgreSQL

Use case: Caching, session state, audit logs
Railway provides managed Postgres
Connection via DATABASE_URL env var

Blob Storage: Cloudflare R2

Use case: PDF storage, document archival
S3-compatible API
Credentials: R2_ACCESS_KEY_ID, R2_SECRET_ACCESS_KEY, R2_BUCKET

Railway Deployment

Setup

Connect GitHub repository
Configure environment variables
Railway auto-detects Dockerfile
Automatic deploys on push to main

Health Check

Add health endpoint for Railway:

@mcp.resource("health://status")
async def health_check() -> str:
    return "ok"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Subscribe to this mod's changes

infrastructure is a skill published in the GitHub repository dsfaccini/siigo-mcp (1 stars, last pushed 10mo ago), licensed MIT. It adds 32 tokens to every session and 612 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
