Catalog
Every x402, MPP, MCP, and skill listing we've indexed, normalized, and enriched.
Extract structured markdown, JSON, and tagged-PDF-ready outputs from PDFs with OpenDataLoader PDF
Convert PDFs into LLM-ready markdown or coordinate-aware JSON, and use the same pipeline for tagged-PDF accessibility workflows when that is the real job to be done.
Extract structured fields from HTML XML and JSON endpoints with Xidel selectors
Use Xidel to pull targeted values from pages, XML documents, or JSON APIs with CSS selectors, XPath, XQuery, or JSONiq expressions.
Extract structured data and attachments from raw email with MailParser
Use MailParser when an agent receives raw RFC822 or MIME email and needs a normalized result with headers, text, HTML, addresses, and attachments. This is for email ingestion and handoff workflows, not for acting as a mailbox client or delivery platform.
Extract schema-shaped JSON from JavaScript-rendered pages with llm-scraper
Open a rendered page, describe the fields you want, and return structured data without hand-maintaining brittle selectors.
Extract schema.org, Open Graph, and JSON-LD metadata from web pages for indexing
Uses extruct to pull machine-readable metadata from raw HTML so an agent can classify, deduplicate, or enrich pages without brittle full-page parsing. It is best for metadata harvesting workflows, not for crawling an entire site or rendering JavaScript-heavy pages.
Extract reusable coding-agent memory from past sessions with Lerim
Watch Claude Code, Codex CLI, Cursor, or OpenCode sessions, extract durable project memory, and keep it locally as reusable markdown.
Extract invoice fields from vendor PDFs into structured records
Uses invoice2data to turn invoice PDFs into structured JSON, CSV, or XML using supplier-specific templates. This is for repeatable invoice field extraction and renaming workflows, not for full accounting system automation or generic OCR catalog listings.
Extract data and complete workflows in your real logged-in browser
Use bb-browser when an agent needs to inspect pages, pull data, or complete form-driven tasks inside the user's actual logged-in Chrome session. It is for browser work where normal HTTP fetches fail because the important context lives behind auth, cookies, or internal web apps.
Extract clean article Markdown from web pages with Defuddle
Use Defuddle when an agent needs clean, metadata-rich article text or Markdown from noisy web pages before summarizing, indexing, or archiving them.
Expose Haystack pipelines as webhook endpoints with Hayhooks
Turn an existing Haystack pipeline into an HTTP or MCP endpoint without building and maintaining a custom wrapper service.
Expose FHIR healthcare data resources to MCP agents with review boundaries
Use a FHIR MCP server to query healthcare data resources for documentation and integration workflows while keeping PHI and clinical-use limits explicit.
Expose FastAPI routes as MCP tools with FastAPI-MCP
Mount FastAPI-MCP on an existing FastAPI app so agents can call authenticated route-backed MCP tools with preserved schemas.
Expose approved database operations to MCP clients with MCP Toolbox before ad hoc SQL glue sprawls
Use MCP Toolbox to turn database access into a constrained MCP tool surface, with prebuilt or custom tools that agents can call without hand-rolled wrappers for every project.
Export Obsidian vaults into clean Markdown trees for publishing or downstream processing
Convert Obsidian vault content, wikilinks, and attachments into portable Markdown trees before publishing, indexing, or migrating notes.
Export live HTML slide decks to PDF handouts before review or archival
Uses DeckTape to open an existing HTML slide deck and render it into a reviewable PDF or per-slide screenshots. It fits agent workflows that need a stable handout, attachment, or archive artifact from Reveal.js, Remark, WebSlides, and similar browser-based presentations.
ExifTool Metadata Reader and Writer for Images and Files
ExifTool by Phil Harvey is a comprehensive Perl-based CLI tool for reading, writing, and editing metadata in over 400 file types. It extracts EXIF, IPTC, XMP, GPS, and maker note data from images, videos, audio, PDFs, and documents, making it the industry standard for metadata fo
Execute DevOps delivery and infrastructure workflows with cc-devops-skills
Use generator and validator loops for infra, CI, and platform work so agents ship operational changes with more checks and less improvisation.
Excalidraw Virtual Whiteboard and Diagram SDK
Excalidraw is an open-source virtual whiteboard for creating hand-drawn style diagrams, wireframes, and sketches. With 103k+ GitHub stars, it provides an infinite canvas, real-time collaboration, end-to-end encryption, and a React component library for embedding in custom applica
Exa JS Web Search SDK for AI Applications
exa-js is the official JavaScript SDK for Exa, a web search API built for AI workflows. It gives agents a concrete way to search the web, retrieve page contents, and generate sourced answers from code instead of stitching raw HTTP calls by hand.
Evolve reusable coding-agent skills from failed trajectories with EvoSkill
Mine failed agent runs for reusable skills, benchmark the candidates, and keep only the variants that improve a supported coding agent over your baseline.
Evidence BI-as-Code SQL and Markdown Analytics Framework
Evidence is an open-source framework for building data products with SQL and Markdown. It generates interactive dashboards and reports as static sites, providing a code-driven alternative to drag-and-drop BI tools with version control and reproducibility built in.
Evaluate long-horizon agents against WildClawBench
Use WildClawBench to benchmark agents on hard end-to-end OpenClaw tasks covering tool orchestration, multimodal work, coding, safety, and long-horizon planning.
Evaluate B2B software vendors by interrogating their agents and scoring the evidence with buyer-eval-skill
Use Claude Code to run a structured vendor diligence workflow that questions vendor agents, cross-checks claims, and returns evidence-backed scorecards.
Estimate Terraform and OpenTofu cost deltas before infrastructure changes merge with Infracost
Show projected cloud cost increases or savings from Terraform and OpenTofu plans before a PR merges.
