Open Source Agent Tools
Production-grade tools for AI agents. MCP servers, knowledge infrastructure, and context management. Built with TypeScript. Free and open source.
We're building Opafex in the open. These tools are extracted from our core platform and published as standalone packages that any developer can use — MCP servers for Claude Code, Cursor, and VS Code, plus infrastructure for building smarter agents.
@opafex/mcp-enrichment
Multi-source entity enrichment. Company data, contact lookup, email verification, phone validation. Clearbit, Hunter.io, and Twilio with built-in mock mode and pluggable caching.
101 tests · 17.3 kB · v0.1.1
@opafex/mcp-file-processor
Universal text extraction for RAG pipelines. PDF, DOCX, CSV, JSON, Markdown, HTML, and code files. Keyword extraction, language detection, configurable chunking.
53 tests · 13.7 kB · v0.1.1
@opafex/mcp-shared
The shared bootstrap for all Opafex MCP servers. Server factory, pluggable caching, typed config, logging, 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.
13 tests · 37.9 kB · v0.1.0
The packages are extracted from a platform that speaks open standards. Agents consume tools and connect to the world the same way you build — no proprietary lock-in.
Model Context Protocol
Point an agent at any remote MCP server — real handshake, live tools/list — and it gains those tools instantly. A curated catalog (DeepWiki, GitMCP) is built in.
Agent-to-Agent (A2A)
Every agent ships its own A2A agent card (spec v0.3.0) over JSON-RPC, so agents delegate work to one another across your workspace.
REST, OpenAPI & SDK
Connect any REST API; discover_api maps an OpenAPI or Swagger spec automatically, with raw HTTP as the fallback. An SDK bridge adds real entity discovery for GitHub and Railway.
66 integrations, 443 operations
A curated registry spanning CRM, project management, comms, email, storage, dev tools, payments, accounting, ecommerce, design, forms, and signing.
- Web Research — Two-stage interpreted search with query reasoning
- Approval Queue — Intelligent human-in-the-loop with auto-approval learning
Use our dev kit to scaffold production-ready MCP servers in seconds.
