ServiceGraph Agent Skills

Datasets for founders — where to launch, who to email, who to hire.

Agent Skills for ServiceGraph — structured, metrics-enriched business datasets your agent can filter, rank, and pull contact data from. One filter DSL, one credit balance, many datasets:

<p align="center"> <img src="assets/servicegraph-datasets.png" alt="ServiceGraph datasets — product directories, business directories, newsletters, agencies, with subreddits and influencers coming soon" width="820" /> </p>

Dataset	Size	Enriched with
Agencies (US professional-services firms)	110k+	services · size · location · ratings
Business directories	3,500+	industry · domain rating · traffic
Product directories	850+	submission policy · domain rating · traffic
Newsletters	50k+	subscribers · topics · post cadence
subreddits, influencers	coming soon

The branded servicegraph skill works against every dataset — say "servicegraph" and your agent discovers what datasets exist, learns each one's schema and filters, searches free, and unlocks detail with credits. The specific find-* skills cover two datasets today. For the Agencies dataset — law, marketing, design, consulting, accounting, IT services, AI/ML, web development, engineering, HR, PR, cybersecurity, and more — filterable by industry, services, location, size, ratings, and third-party listings. And for the Product directories dataset — where to launch a software product and earn backlinks — covering general product/SaaS launches, MCP-server registries, and AI-tool / AI-agent / agent-skill directories, ranked by Domain Rating and organic traffic. More per-use-case skills for the newsletter and other datasets land here as they ship — same install, same API key, same DSL.

Compatible with 19+ AI agents including Claude Code, Codex, Cursor, GitHub Copilot, Gemini, Cline, Goose, Windsurf, and any other harness that supports the Agent Skills format.

Installation

API key: browsing, filtering, and brief cards are free, but every call needs a key. Create one at servicegraph.co/profile/api-keys (2,000 free credits on signup, no card) and put it in your shell or .env.local as SERVICEGRAPH_API_KEY=vk_…. Skills prompt for it on first use and never read the value into the model's context.

Available Skills

Any dataset

<details open> <summary><strong>servicegraph</strong> — the branded entry point</summary>

The generic, dataset-agnostic way to drive ServiceGraph. Launch it by naming the brand; it discovers what datasets exist and each one's schema and filters through the API, searches free brief rows, and unlocks contact + metric detail with credits — no datasets or fields hardcoded, so it stays correct as new data lands.

Use when:

• "Use ServiceGraph to find …"
• "What datasets does ServiceGraph have?"
• "Search ServiceGraph for … / look this up in ServiceGraph"
• "Pull contacts from ServiceGraph for these domains"
• The dataset you need has no specific skill below yet

Product directories dataset

Each row is a directory you submit to — not a firm and not a product. These skills answer where to launch a software product and earn backlinks: they rank listing sites by Domain Rating (free in every result, so you shortlist for zero credits) and unlock the submission note (how to submit, and whether the listing grants a backlink) plus organic traffic with credits. Global catalog, not US-only.

<details open> <summary><strong>find-product-directories</strong> — the umbrella</summary>

Find and rank directories to submit a SaaS, software product, app, or startup to — SaaS review sites, launch platforms (Product Hunt and its alternatives), and general software directories. Defers to find-mcp-directories and find-ai-directories for those niches.

Use when:

• "Where can I submit my B2B SaaS to get backlinks and launch-day traffic?"
• "Give me a list of Product Hunt alternatives to launch our app on"
• "Here are 10 software directory domains — pull submission details and rank by DR"

</details> <details> <summary><strong>find-mcp-directories</strong></summary>

Find and rank MCP-server registries (Model Context Protocol) — where to publish a server so agent builders discover it, ranked by domain authority.

Use when:

• "Where do I list my MCP server?"
• "Best MCP directories and registries to submit our server to for backlinks"
• Indirect: "we just built an MCP server — where do we publish it?"

</details> <details> <summary><strong>find-ai-directories</strong></summary>

Find and rank directories for AI tools, AI agents, and agent skills / plugins — where to list an AI product for backlinks and discovery. Defers to find-mcp-directories when the artifact is specifically an MCP server.

Use when:

• "Where can I list my AI tool to get backlinks and discovery?"
• "Directories to submit my AI agent / where do I publish our agent skill?"
• "Rank the top AI tool directories by domain rating for our SEO push"

</details>

Prefer MCP? Use the hosted server.

If your harness speaks the Model Context Protocol, skip the skill install and point it at the hosted MCP server:

https://mcp.servicegraph.co

• Transport: Streamable HTTP
• Auth: OAuth 2.1 + PKCE with Dynamic Client Registration — your harness opens a browser tab on first use; you sign in on servicegraph.co and are bounced back. No client ID or secret to copy around, no API key to paste.

Claude Code

claude mcp add --transport http servicegraph https://mcp.servicegraph.co

Claude Desktop

Settings → Connectors → Add custom connector, then paste:

https://mcp.servicegraph.co

The OAuth handshake runs in your browser on first use.

Codex CLI

~/.codex/config.toml:

[mcp_servers.servicegraph]
url = "https://mcp.servicegraph.co"

Cursor and other JSON-config clients

.cursor/mcp.json (or the equivalent for your harness):

{
  "mcpServers": {
    "servicegraph": {
      "url": "https://mcp.servicegraph.co"
    }
  }
}

Usage

Skills are automatically available once installed. The agent will pick the right one when it detects a relevant task.

Examples:

Find me three boutique IP law firms in California that handle patent
prosecution for hardware startups.

Need a shortlist of mid-size SEO agencies in NY or NJ with a strong B2B
SaaS portfolio.

We're hiring a CPA firm for a Delaware C-corp Series A audit.
Recommend 5 options under 50 people.

Here are 12 marketing agency domains I scraped — pull contact info and
confirm which are in the US.

How it works — browse free, unlock with credits

Every dataset lives behind the same per-dataset URL shape and the same filter DSL. For the agencies dataset the id is pro_services:

GET  /v1/datasets/pro_services/fields    →  field catalog + DSL grammar · free
GET  /v1/datasets/pro_services/check     →  validate a filter · free
GET  /v1/datasets/pro_services/search    →  brief firm cards · free
GET  /v1/datasets/pro_services/{apex}    →  one row (brief; detail if unlocked) · free
POST /v1/datasets/pro_services/unlocks   →  full contact bundle · 10 credits/row

Discovery, filtering, and brief cards are free — you only spend credits to unlock a row's full contact detail (URL, phone, email, social, address). An unlock lasts 30 days and re-fetching within that window is free.

• 2,000 free credits on signup, no card.
• 10 credits per row (~$0.10). Top-ups: $10 / 1,000 credits, $80 / 10,000 (20% off). Credits never expire.

Filter DSL

One query parameter, GitHub-search-style. AND binds tighter than OR; -x / NOT x for negation; tag@evidence for the service_provided field. Any bareword is a free-text keyword search across firm name, brand, title, meta description, and legal name.

industry:legal state:CA,NY -company_size_signal:solo
industry:management_consulting service_provided:strategy-consulting@high
dental industry:marketing_agency
rating>=4 review_count_total>=20 has:clutch
(web3 OR blockchain) state:CA

The field catalog (kinds, operators, allowed values) is discoverable at runtime via /v1/datasets/pro_services/fields.

Why structured beats search

• Filter, don't grep. Industry, services, location, size, rating, domain authority, traffic, third-party listings — all queryable as a single filter string, not a wall of fuzzy web results.
• Metrics built in. Every row carries the signals you'd otherwise scrape by hand — agency ratings, directory DR/traffic, newsletter subscriber counts — so an agent can rank, not just list.
• Cheaper than scraping. Browse and filter for free; pay only for the contact rows you actually want, ~$0.10 each, 30-day access, credits never expire. Beats Google, ChatGPT guesses, and stale Notion/Twitter lists.

Skill structure

Each skill follows the Agent Skills Open Standard:

• SKILL.md — required manifest with frontmatter (name, description, metadata)

The skills in this repo are single-file. No bundled scripts or references yet — the API is small enough that the agent does fine with prose + copy-pasteable curl examples.
