Open Source Agent Tools
Production tools for AI agents — MCP servers, knowledge infrastructure and context management. All TypeScript, free and open source.
We build Opafex in the open and publish these tools as standalone packages. MCP servers for Claude Code, Cursor and VS Code, plus agent infrastructure.
@opafex/mcp-enrichment
Multi-source enrichment covers company data, contact lookup, email verification and phone validation. It uses Clearbit, Hunter.io and Twilio with mock mode and pluggable caching.
v0.1.1 · source on GitHub
@opafex/mcp-file-processor
Text extraction for RAG pipelines, with keyword extraction, language detection and chunking. PDF, DOCX and CSV plus JSON and Markdown plus HTML and code.
v0.1.1 · source on GitHub
@opafex/mcp-shared
The shared bootstrap for every Opafex MCP server. Server factory, pluggable caching and typed config plus logging and error handling.
@opafex/knowledge-grid
Structured context for AI agents. A layered knowledge grid that gives your agent the right context in the right priority — so it performs better on every interaction. 4-layer lattice, 9 domains, intent-driven retrieval, token-budgeted prompt composition. Zero dependencies.
v0.1.1 · 246 tests, all passing · source on GitHub
We extracted these packages from a platform that speaks open standards. Agents connect the same way you build, with no proprietary lock-in.
Model Context Protocol
Point an agent at any remote MCP server and use its tools. A built-in catalogue includes DeepWiki and GitMCP.
Agent-to-Agent (A2A)
Every agent ships an A2A agent card (spec v0.3.0) over JSON-RPC. Agents delegate work to one another across your workspace.
REST, OpenAPI & SDK
Connect any REST API — discover_api maps OpenAPI or Swagger specs. Fallback is raw HTTP, plus SDK entity discovery for GitHub and Railway.
58 providers, 73 services, 499 operations
The registry spans CRM, project management and comms plus email and storage. Dev tools, payments and accounting plus ecommerce, design and forms and signing.
