Your agent codes against
yesterday's docs
Libraries ship breaking changes weekly. Training data is months old. When your coding agent generates an API call that no longer exists, you debug the agent instead of the code. Spider gives agents access to current documentation so they write code that actually works.
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, migration guides, all current and token-efficient.
Read API references as clean markdown
Fetch API reference pages and get clean, structured markdown your agent can parse. Method signatures, parameter tables, and code examples preserved in a token-efficient format.
Track breaking changes
Crawl changelogs and release notes to catch breaking changes before your agent generates code using 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.
