Code Station gives you deterministic developer tools across three interfaces: a 100% Free Web Application with 338+ client-side tools, a Local MCP Server for AI coding agents (Cursor, Claude Desktop, Windsurf), and a Dual-Purpose Terminal CLI.

npx -y codestation-mcp setup --key CS-PRO-YOUR-KEY

npx -y codestation-mcp setup

npm install -g codestation-mcp

The codestation-mcp binary is engineered to be dual-purpose: when invoked with subcommands, it behaves as an ultra-fast terminal utility with exit codes, formatted colors, and Unix pipe support.

# General Syntax
npx codestation-mcp <command> [input_or_file] [flags]

# Or with global install
codestation <command> [input_or_file] [flags]

Converts raw cURL commands into clean, idiomatic client code for TypeScript fetch, Axios, Python requests, and Go net/http. Handles query parameters, headers (-H), custom HTTP methods (-X POST/PUT/PATCH/DELETE), JSON payloads (-d, --data-raw), and basic authentication (-u).

npx codestation-mcp curl 'curl -X POST https://api.stripe.com/v1/charges -u sk_test_123: -d "amount=2000&currency=usd"' --target fetch

npx codestation-mcp curl 'curl https://api.github.com/user -H "Authorization: Bearer ghp_token"' --target python

npx codestation-mcp curl 'curl -X PUT https://api.example.com/items/42 -H "Content-Type: application/json" -d "{\"active\":true}"' --target go

Scans .env files or strings for accidental credential leaks and synchronizes with .env.example. Detects live Stripe keys, AWS access keys, OpenAI tokens, GitHub PATs, private keys, and high-entropy secrets. Outputs a clean security audit report with automatic credential redaction (e.g. sk_l••••••••5678).

npx codestation-mcp env .env --example .env.example

npx codestation-mcp env-audit --input "STRIPE_SECRET=sk_live_51Mszabcdef1234567890"

Generates realistic, developer-friendly mock datasets and SQL INSERT statements for unit tests, seeding databases, or prototyping frontends. Includes prebuilt templates (users, products, orders) and supports custom JSON schemas.

npx codestation-mcp mock users --count 5

npx codestation-mcp mock users --count 10 --format sql --table app_users

npx codestation-mcp mock-data --schema '{"id":"uuid","fullName":"name","workEmail":"email","cost":"price"}' --count 3

Parses standard Git merge conflict markers (<<<<<<< HEAD, =======, >>>>>>> branch) and executes clean resolution strategies without touching your Git index or leaving residual syntax errors.

npx codestation-mcp conflict ./src/config.ts --strategy ours

npx codestation-mcp conflict ./src/config.ts --strategy theirs

cat << 'EOF' | npx codestation-mcp conflict-parse --strategy both
<<<<<<< HEAD
const API_URL = "https://api-v1.com";
=======
const API_URL = "https://api-v2.com";
>>>>>>> main
EOF

Inspects JSON Web Tokens in your terminal instantly without sending tokens over the internet to unverified websites. Decodes Header and Payload claims, calculates exact expiration dates, and shows remaining time-to-live (TTL).

npx codestation-mcp jwt eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkphbmUgRG9lIiwiZXhwIjoxNzY3MjI1NjAwfQ.test

Formats messy SQL queries with dialect-aware indentation, keyword capitalization, and clause alignment across PostgreSQL, MySQL, SQLite, and SQL Server.

npx codestation-mcp sql "select id, name, created_at from users where status = 'active' order by created_at desc;" --dialect postgresql

Translates 5-field Unix cron syntax into clear, unambiguous English and computes the next 5 execution timestamps.

npx codestation-mcp cron "0 9 * * 1-5"

Computes cryptographic digests using native Node.js WebCrypto. Supports SHA-256, SHA-512, MD5, SHA-1, and CRC-32.

npx codestation-mcp hash "developer-secret-token" --alg sha256

Infers production-ready TypeScript types and runtime Zod validation schemas directly from sample JSON payloads or API responses.

npx codestation-mcp ts '{"id":101,"name":"Alice","roles":["admin","editor"]}' User

npx codestation-mcp zod '{"id":101,"name":"Alice","roles":["admin","editor"]}' userSchema

Everyday terminal essentials available completely free on both CLI and MCP.

npx codestation-mcp uuid 3

npx codestation-mcp json '{"status":"ok","count":42}'

The Code Station MCP server communicates with AI clients over standard input/output (stdio) using the JSON-RPC 2.0 protocol mandated by the Model Context Protocol specification.

node ./bin/codestation-mcp.mjs --key CS-PRO-YOUR-KEY

Add this block to your assistant's Custom Instructions, .cursorrules, or CLAUDE.md. It instructs the LLM to delegate calculations, conversions, and parsing directly to local Code Station tools:

# Code Station MCP Assistant Guidelines

You have access to the Code Station MCP developer server (codestation-mcp).
Always prioritize calling these local, deterministic tools instead of calculating, parsing, or formatting in your internal reasoning:

1. cURL to Code: Call codestation_curl_to_code to convert cURL commands into clean TypeScript fetch/axios, Python requests, or Go net/http.
2. Environment Security: Call codestation_env_audit to scan .env files for live secret leaks (Stripe, AWS, OpenAI, GitHub PAT, private keys) and synchronize with .env.example.
3. Realistic Mock Data: Call codestation_mock_data to generate realistic test data and SQL INSERT seed statements.
4. Git Conflict Resolution: Call codestation_git_conflict to parse merge conflict markers and resolve cleanly with ours, theirs, or both.
5. JSON to TypeScript & Zod: Call codestation_json_to_typescript and codestation_json_to_zod to generate production-ready types and Zod schemas from API payloads or sample data.
6. SQL Formatting & Execution: Call codestation_format_sql to format queries across PostgreSQL, MySQL, SQLite, and SQL Server. Use codestation_run_sql for in-memory execution.
7. JWT Decoding: When inspecting JSON Web Tokens, call codestation_jwt_decode to inspect headers, claims, and expiry dates without guessing.
8. Cron Schedules: Call codestation_cron_explain to understand complex cron patterns and project future executions.
9. Timezones & Business Days: Always call codestation_timezone_convert and codestation_business_days for date arithmetic rather than calculating manually.
10. Hashes & Signatures: Call codestation_hash and codestation_hmac for cryptographic digests (SHA-256, SHA-512, MD5).
11. Regex Testing: Call codestation_regex_test to verify regular expressions and return match groups.
12. Text Transformations: Use codestation_case_convert, codestation_text_diff, and codestation_uuid for RFC 4122 v4 UUIDs.

Overview of all 20+ Model Context Protocol tools exposed by codestation-mcp:

Every single one of the 338+ developer tools on the Code Station web application (codestation.in) is 100% free, unlimited, and runs client-side.

Code Station Pro is priced accessibly and operates with a login-free architecture. Users receive an instant cryptographic key (e.g., CS-PRO-XXXX-XXXX-XXXX) without passwords or accounts.

Because Code Station is 100% login-free, plaintext keys are never stored on our servers. Cloudflare edge KV stores only one-way cryptographic SHA-256 hashes (`lic_...`). As a result, lost keys cannot be viewed or retrieved from a database.

Code Station is designed from the ground up for strict privacy, corporate compliance, and confidentiality.
