Live documentation as an agent tool.
Libraries ship breaking changes weekly. Training data is months old. Spider gives coding agents access to current documentation, API references, and changelogs so they write code against real APIs, not training-cutoff snapshots.
# Add Spider to your IDE claude mcp add spider -- npx -y spider-cloud-mcp # Then ask naturally: "Read the Stripe Checkout docs and add a payment form to our app" # Agent uses spider_crawl to fetch live docs
Training cutoffs cost real debugging time.
An agent that generates code using a deprecated API signature creates a bug you have to trace back through generated output, documentation, and changelogs. The fix is giving the agent current docs before it writes a single line.
Agent reads training data from 6 months ago Generates code using stripe.charges.create() Stripe recommends PaymentIntents, not Charges → Code works but uses a legacy API you'll have to migrate later
Agent crawls current Stripe docs Reads latest API reference + migration guide Generates code using stripe.checkout.sessions.create() → Uses the recommended API from the start
What coding agents can do.
Crawl documentation sites
Point an agent at any docs URL and get clean markdown for every page. Framework docs, API references, and migration guides arrive token-efficient and current.
Read API references as markdown
Fetch API reference pages and get structured markdown an agent can parse. Method signatures, parameter tables, and code examples preserved.
Track breaking changes
Crawl changelogs and release notes to catch breaking changes before your agent generates code against a removed method or renamed parameter.
Find solutions in real time
Search the web for error messages, Stack Overflow answers, and GitHub issues. Ground debugging in current community knowledge, not stale training data.
Works with your IDE
One command to add Spider as an MCP server in Claude Code, Cursor, or Windsurf. Your coding assistant gets crawl, search, and extract tools instantly.
Reach protected docs
Many documentation sites use bot protection. Spider handles fingerprinting, proxies, and challenges automatically for public docs. It does not access login-gated or paywalled content.
Add it in one line.
Install the MCP server and your coding agent gets web access immediately. No wrapper code, no API client setup, no token management.
# Add to any MCP-compatible IDE claude mcp add spider -- npx -y spider-cloud-mcp # Then ask your agent naturally: "Read the Next.js 15 App Router docs and add server actions to our checkout form" # Agent crawls docs, reads current API, # generates working code
Keep reading.
Give your coding agent current docs.
Add Spider and stop debugging code that was written against a deprecated API.
