Infrawise

sidd27.github.io/infrawise — Understand your infrastructure, not just your code.

Infrawise gives AI coding assistants deterministic infrastructure awareness.

It statically analyzes your codebase, cloud infrastructure, and database schemas, then exposes that context through MCP so tools like Claude Code can understand your actual tables, indexes, query patterns, and service relationships instead of guessing from source files alone.

Why this exists

New software developers don't write wrong code. Claude Code writes wrong code and they ship it. Infrawise is the only thing standing between Claude Code's generated output and a production incident.

AI coding assistants can read your source files but have no deterministic knowledge of your infrastructure. They do not know which GSIs exist, how tables are partitioned, which functions already trigger scans, or where indexes are missing. So they guess.

Infrawise replaces guessing with infrastructure-aware context.

Without Infrawise, an AI assistant might:

• Suggest a .scan() on your Orders table that has 50M rows

• Recommend adding a GSI on status that you already have

• Write a SELECT * when you need to keep query cost low

• Not notice that 5 functions are already hammering the same partition key

With Infrawise, it knows:

• Your exact table schemas, partition keys, sort keys, and GSIs

• Which functions query which tables and how

• Which patterns are already flagged as high severity

• The exact CREATE INDEX SQL or GSI config for your tables — not generic advice

What Infrawise is not

Infrawise is not an AI agent framework, an infrastructure provisioning tool, an observability platform, or a cloud management dashboard.

It is a deterministic infrastructure intelligence layer for AI-assisted development.

Installation

npm install -g infrawise

or use without installing:

npx infrawise start --claude

Quick start

cd your-project
infrawise start --claude

That's it. Infrawise will:

1. Probe your environment and generate infrawise.yaml (first time only — asks which AWS profile to use only if you have several)

2. Scan your AWS services, databases, and codebase

3. Write .mcp.json so your editor auto-connects on every future launch

4. Open Claude Code with all 16 MCP tools ready

Every time after:

claude    # no infrawise command needed — editor manages the connection

Analysis is cached for 24 hours. When the cache is stale, infrawise serve --stdio (spawned automatically by your editor) refreshes it at session start. File changes are detected within the session and the code graph is updated automatically.

Findings (3 total)

1. [HIGH] Full table scan detected on DynamoDB table "Orders"
   listAllOrders() scans without any filter — reads every item in the table.
   Recommendation: Replace Scan with Query using a partition key or add a GSI.

2. [MEDIUM] PostgreSQL table "users" has no index on column "email"
   Filtering on "email" causes sequential scans.
   Recommendation: CREATE INDEX CONCURRENTLY idx_users_email ON users(email);

3. [MEDIUM] DynamoDB table "Sessions" accessed by 6 distinct code paths
   High access concentration may create hot partition issues at scale.

Using with AI coding assistants

Claude Code (recommended)

infrawise start --claude

Writes .mcp.json to your project root and opens Claude Code. Claude Code reads .mcp.json automatically on every launch and manages the infrawise serve --stdio process — no server to start, no ports to configure.

Cursor

infrawise start --cursor

Writes .cursor/mcp.json and opens Cursor. All 16 infrawise tools are available in Cursor's MCP panel.

Any editor (no flag)

infrawise start

Writes .mcp.json and exits. Open whichever editor you prefer — point it at infrawise serve --stdio --config /path/to/infrawise.yaml as an MCP server command.

HTTP transport (alternative)

If your editor or workflow requires an HTTP MCP endpoint instead of stdio:

infrawise serve    # starts server at http://localhost:3000/mcp

Add to your editor's MCP config:

{
  "mcpServers": {
    "infrawise": {
      "url": "http://localhost:3000/mcp"
    }
  }
}

MCP tools

CLI reference

infrawise analyze options

# Export a shareable findings report
infrawise analyze --output report.md

# Only show high-severity issues
infrawise analyze --severity high

# High-severity issues only, saved to a file
infrawise analyze --severity high --output report.md

infrawise check options (CI/CD)

check runs a fresh analysis and sets a non-zero exit code when blocking findings exist, so it can gate a pipeline without an AI editor.

# Block a deploy if any high-severity finding exists (exit 1)
infrawise check

# Stricter gate — fail on medium and above
infrawise check --fail-on medium

infrawise serve options

Configuration

infrawise.yaml is generated by infrawise start (or infrawise start --interactive for the guided wizard) and lives in your repo root. Every service must be explicitly enabled: true — infrawise never connects to anything not listed in config.

Connection strings support ${ENV_VAR} substitution so passwords never need to be committed:

postgres:
  enabled: true
  connectionString: postgresql://infrawise_ro:${DB_PASSWORD}@host:5432/mydb

Full example:

project: payments-service

aws:
  profile: default # AWS profile from ~/.aws/credentials
  region: ap-south-1

dynamodb:
  enabled: true
  includeTables: # omit to include all tables
    - Orders
    - Users

postgres:
  enabled: true
  connectionString: postgresql://infrawise_ro:${DB_PASSWORD}@host:5432/mydb

mysql:
  enabled: false
  connectionString: ''

mongodb:
  enabled: false
  connectionString: ''

sqs:
  enabled: true

sns:
  enabled: true

ssm:
  enabled: true
  paths: [] # filter by prefix e.g. ["/myapp/prod"]

secretsManager:
  enabled: true

lambda:
  enabled: true
  includeFunctions: # omit to include all functions
    - myFunction
    - anotherFunction

eventbridge:
  enabled: true

rds:
  enabled: false

s3:
  enabled: false

apiGateway:
  enabled: false

cloudwatchLogs:
  enabled: false
  logGroupPrefixes: []
  windowHours: 24

analysis:
  sampleSize: 100
  hotPartitionThreshold: 5
  hotPartitionThresholds:
    high-traffic-table: 12

AWS setup

Infrawise is read-only. Minimum IAM policy required:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": ["dynamodb:ListTables", "dynamodb:DescribeTable"],
      "Resource": "*"
    }
  ]
}

For SSO profiles, log in before running infrawise:

aws sso login --profile myprofile

PostgreSQL setup (optional)

Create a read-only user for infrawise:

CREATE USER infrawise_ro WITH PASSWORD 'yourpassword';
GRANT CONNECT ON DATABASE yourdb TO infrawise_ro;
GRANT USAGE ON SCHEMA public TO infrawise_ro;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO infrawise_ro;

For Amazon RDS: allow inbound on port 5432 from your machine's IP in the security group.

Analysis capabilities

Infrawise has two analysis layers:

Infrastructure analysis (all languages)

Works from AWS APIs, database schema introspection, and IaC files — no dependency on application code:

Code correlation analysis (TypeScript / JavaScript)

Uses ts-morph AST analysis to detect which functions call which tables and how:

Non-TypeScript/JavaScript projects still get full value from infrastructure-level analyzers — code correlation (function-to-table mapping, N+1 patterns) is skipped.

The scanner supports: AWS SDK v3/v2 for DynamoDB, pg/Prisma/Knex for PostgreSQL, mysql2/Knex for MySQL, driver/Mongoose for MongoDB, AWS SDK v3 for SQS/SNS/SSM/Secrets/Lambda, and kafkajs for Kafka topics (producer/consumer).

How it works

1. Infrawise scans your repository and infrastructure metadata

2. A graph engine maps services, schemas, indexes, and query patterns

3. Rule-based analyzers detect infrastructure and query anti-patterns

4. The resulting context is exposed through MCP

5. AI coding assistants query this context while generating code

Deterministic analysis

Infrawise does not use an LLM to analyze your infrastructure. All extraction and analysis are deterministic: AST parsing, schema introspection, rule-based analyzers, and graph correlation. LLMs are only consumers of the generated context through MCP.

Security

• Read-only — never writes to AWS or your database, never executes DDL

• Local-first — everything runs on your machine, nothing sent to external servers

• No telemetry — zero data collection

• Credentials — uses your existing AWS credential chain, never stored by infrawise

🔒 Security & Project Naming Note

You might see this package flagged on certain supply-chain security scanners under "deceptive naming." This is a false positive triggered by automated tools because of the prefix "infra." This project is completely safe, independent, and unaffiliated with any commercial trademarks.

Current limitations

• Code-level correlation supports TypeScript and JavaScript only

• Dynamically constructed queries may not always be resolved statically

• Runtime tracing is not yet implemented

• Large monorepos may require future incremental analysis optimization
