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; the user enters their email + one-time code on api.servicegraph.co and is bounced back. No client ID or secret to copy around.

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 — the four-tier funnel

GET /v1/tags         →  field catalog · free · anonymous
GET /v1/check        →  validate filter · free · anonymous
GET /v1/explore      →  counts + breakdowns · free · anonymous
GET /v1/search       →  brief firm cards · 200/month free
GET /v1/get/{id}     →  full bundle (url, phone, email) · 50/month free

Skills know to walk down the funnel: cheap tiers first, expensive tiers only on shortlisted firms. Re-pages and overlapping queries are free — the quota counts only unique firm-views per calendar month.

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

Field catalog (kinds, operators, allowed values) is discoverable at runtime via /v1/tags.

Why structured beats search

• Filter, don't grep. Industry, services, location, size, rating, third-party listings — all queryable as a single filter string. Not a wall of fuzzy web results.

• Try before you sign up. /v1/explore is fully anonymous. Get counts and breakdowns for any filter to size the candidate pool before spending an API call.

• Quota rewards focus. 200 unique firm-views per month free. Re-paging or overlapping queries are free; only new firms count.

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.
