📄 Description

Summary

  • Adds a community middleware integration page for langchain-dns-aid, a cross-provider middleware for DNS-based agent discovery
  • Adds entry to the community integrations table on the middleware index page
  • Adds a code sample for the agent discovery pattern

What is DNS-AID middleware?

langchain-dns-aid is a LangChain AgentMiddleware that enables agents to discover and connect to other agents using DNS via the DNS-AID protocol (SVCB records, RFC 9460).

Key features:

  • Auto-publishes the agent to DNS on startup (before_agent hook)
  • Auto-unpublishes on shutdown (after_agent hook) to prevent stale records
  • Provides dns_aid_discover, dns_aid_publish, dns_aid_unpublish tools
  • Cross-provider: works with any LLM (OpenAI, Anthropic, AWS, etc.)

Files changed

File Change
src/oss/python/integrations/middleware/dns-aid.mdx New integration page
src/oss/python/integrations/middleware/index.mdx Added to community table
src/code-samples/langchain/middleware-dns-aid-discovery.py Code sample

Test plan

  • Verify the integration page renders correctly with Mintlify preview
  • Verify links from index page to integration page work
  • Verify PyPI badge renders correctly
