Context7 AI features, pricing and GDPR (October 2026)

Context7 is a documentation service from Upstash that gives AI coding assistants current, version-specific library documentation and code examples through an MCP server and an API, aimed at developers and engineering teams.

Context7 indexes documentation and code snippets from library sources and returns the parts that match a question, so that assistants such as Cursor or Claude Code work with the right library version. The MCP server exposes two tools, resolve-library-id and query-docs, and the repository lists support for more than 30 other MCP clients. A Search API, private repositories for teams and a self-hosted option for enterprises complete the offer. Upstash, Inc. is based in California. The MCP server code is MIT licensed and the repository had more than 62,000 GitHub stars on October 1, 2026.

• Supplies agents with current library docsThe MCP server turns a library name into an identifier and fetches matching documentation for the requested version. Coding agents then write code against current APIs instead of outdated training data, and developers spend less time correcting invented function calls.
• Finds snippets from plain questionsThe Search API lets an agent ask a question without naming a library. The service identifies relevant libraries, extracts matching code snippets and reranks them before returning results with library name and source URL, so the agent can cite where an answer comes from.
• Screens documentation for unsafe contentAccording to the vendor, a two-pass check screens indexed documentation for prompt injection and unsafe code, and trust scoring keeps unsafe content out of agent context. Teams that connect agents to community-contributed libraries get a safeguard against poisoned snippets.

• The MCP server code is open source under the MIT license, while the API backend, parsing engine and crawling engine remain proprietary, according to the repository.
• Enterprise adds SSO (SAML or OIDC), a self-hosted Docker deployment in a private network and, per the vendor, US or EU data residency.
• Pricing is per seat with included API calls and a separate charge for parsing private repositories, and a free plan covers public repositories.

Context7 belongs to Upstash, Inc., based in California; the service is offered online, and the Enterprise plan offers US or EU data residency.

Context7 libraries are community-contributed, so treat retrieved snippets as untrusted input and keep prompt injection defenses on the agent side too. The Free plan stops at 1,000 API calls per month, and private repositories need Pro. SSO, a self-hosted option and SOC 2 belong to Enterprise. The vendor says queries are processed locally with 30-day retention; ask for the data processing terms.
