What it does

Servicegraph is an agent skill from jeremylongshore/tons-of-skills-marketplace. The branded entry point to ServiceGraph — use whenever the user explicitly names ServiceGraph — "use ServiceGraph to…", "what datasets does ServiceGraph have", "search ServiceGraph for…", "pull contacts from ServiceGraph for these domains", "how many credits do I have on ServiceGraph". ServiceGraph is a multi-dataset platform of metrics-enriched business data for founders — where to launch, who to email, who to hire. This skill explains how to drive the API (api.servicegraph.co / mcp.servicegraph.co) against ANY…

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • The user explicitly names ServiceGraph — use ServiceGraph to…
  • What datasets does ServiceGraph have
  • Search ServiceGraph for…
  • Pull contacts from ServiceGraph for these domains

Example prompts

  • “use ServiceGraph to…”
  • “what datasets does ServiceGraph have”
  • “search ServiceGraph for…”
  • “/servicegraph”

Requirements

  • A credential in SERVICEGRAPH_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Bash(curl:*), mcp__servicegraph__list_datasets, mcp__servicegraph__describe_dataset, mcp__servicegraph__list_fields, mcp__servicegraph__list_field_values, mcp__servicegraph__check_filter, mcp__servicegraph__translate_intent, mcp__servicegraph__search_dataset, mcp__servicegraph__get_row, mcp__servicegraph__unlock_rows, mcp__servicegraph__get_credit_balance

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(curl:*)
    • mcp__servicegraph__list_datasets
    • mcp__servicegraph__describe_dataset
    • mcp__servicegraph__list_fields
    • mcp__servicegraph__list_field_values
    • mcp__servicegraph__check_filter
    • mcp__servicegraph__translate_intent
    • mcp__servicegraph__search_dataset
    • mcp__servicegraph__get_row
    • mcp__servicegraph__unlock_rows

    …and 1 more on the same allowed-tools line.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • mcp.servicegraph.co
    • api.servicegraph.co

    Also links to:

    • servicegraph.co
    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SERVICEGRAPH_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    From compatibility in the SKILL.md frontmatter.

Context cost

Servicegraph loads about 1.9k tokens when it runs. Until then it costs about 259 tokens; SKILL.md has 768 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~259
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

ServiceGraph is a multi-dataset platform of metrics-enriched business data for founders — where to launch, who to email, who to hire. This skill explains how to drive the API (api.servicegraph.co / mcp.servicegraph.co) against ANY dataset — discover what datasets exist, discover a dataset's schema and filters, search free brief rows, and unlock contact + metric detail with credits.

servicegraph

Overview

The generic way to drive ServiceGraph — a platform of metrics-enriched business datasets for founders: where to launch, who to email, who to hire. Use this skill when the user explicitly reaches for ServiceGraph. For intent-first asks that don't name the brand ("find me a CPA firm"), a specific find-* skill is the better fit — defer to it.

There is no single global catalog, and this skill hardcodes nothing about the data. It discovers everything through the API at runtime, so it stays correct as datasets are added, renamed, or re-priced. Discover the datasets from the API, discover each dataset's schema and filters from the API, then search and unlock against it. Never assume a dataset id, a field name, or a price — ask the API.

Prerequisites

  • ServiceGraph access, either:
    • the ServiceGraph MCP server (https://mcp.servicegraph.co) loaded in your harness — this plugin's .mcp.json wires it up; OAuth handles credentials in the harness sandbox, no token enters the model context — or
    • a ServiceGraph API key (vk_…, minted at https://servicegraph.co/profile/api-keys) available as SERVICEGRAPH_API_KEY for the REST path (see Auth below).
  • An HTTP client for the REST path — Bearer-auth with the vk_… key.
Two ways to call

Both speak to the same backend; use whichever your harness has.

  • MCP server (preferred when loaded) — https://mcp.servicegraph.co, tool names contain servicegraph. OAuth handles credentials in the harness sandbox; no token enters the model context.
  • REST — https://api.servicegraph.co, any HTTP client, Bearer-auth with a vk_… key. The universal fallback.

How it works

Everything except unlocking is free — discover, inspect, validate, and browse as much as you like; only revealing detail costs credits.

CapabilityMCP toolRESTCost
Find what datasets exist (ids, sizes, prices)list_datasetsGET /v1/datasetsfree
Discover a dataset's schema + filter fieldsdescribe_dataset, list_fields, list_field_valuesGET /v1/datasets/:id…free
Build & validate a filter (or draft one from plain English)check_filter, translate_intent…/check, …/translate-intentfree
Search → free brief rows (identity + headline metrics)search_dataset…/searchfree
Read an already-unlocked rowget_rowGET /v1/datasets/:id/:apexfree
Unlock rows → reveal contacts + full metricsunlock_rowsPOST …/unlocksspends credits
Check credit balanceget_credit_balanceGET /v1/me/creditsfree

The shape is always the same: discover datasets → discover the dataset's schema → search free briefs → unlock the rows the user picks. Rows are keyed by apex domain (stripe.com, not a full URL). Confirm field and value names against the API before trusting a zero-result search — the filter parser accepts invented values silently.

Auth (REST path)

Keys are vk_* tokens the user mints at https://servicegraph.co/profile/api-keys (free credits on signup). The MCP path needs none of this.

Keep the token out of the model context — never read .env/credential files into context, and route authed calls through a shell wrapper so the key flows from the environment into the Authorization header. On 401, ask the user to set SERVICEGRAPH_API_KEY (env or .env.local) and retry; don't accept the key pasted into chat.

Cost & confirmation

Only unlock_rows spends credits, at the per-row price the dataset reports — read it, don't assume it. Unlocks are atomic (a 402 charges nothing) and cached for the dataset's TTL (re-unlocking within it is free). Confirm the cost with the user before unlocking a batch, and check get_credit_balance first if it's large.

Output

All responses are JSON.

  • Dataset discovery (list_datasets / GET /v1/datasets) returns each dataset's id, size, and unlock pricing — read those, never assume them.
  • Search returns free brief rows keyed by apex domain — identity plus headline metrics — with a per-row unlock hint and the match total.
  • Unlock (unlock_rows / POST …/unlocks) reveals a row's gated detail — contacts plus full metrics — at the per-row price the dataset reports, cached for the dataset's TTL.
  • Credit balance (get_credit_balance / GET /v1/me/credits) returns the current balance.

Errors

  • 401 on the REST path — the key is missing or invalid. Ask the user to set SERVICEGRAPH_API_KEY (env or .env.local) and retry; never accept the key pasted into chat.
  • 402 on unlock — balance is short. Unlocks are atomic, so nothing was charged; report the shortfall and check get_credit_balance.
  • Zero-result searches — the filter parser accepts invented field and value names silently. Re-confirm names via list_fields / list_field_values before trusting an empty result.

Examples

"What datasets does ServiceGraph have?" list_datasets (or GET /v1/datasets) → present each dataset's id, size, and unlock price. Free.

"Search ServiceGraph for design agencies in New York and unlock the top 3." Discover the matching dataset (list_datasets), inspect its schema (describe_dataset / list_fields), validate a filter (check_filter), search_dataset → present the free briefs, confirm the unlock cost with the user, then unlock_rows on the three chosen apexes.

How do I install Servicegraph in Claude Code?

Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill servicegraph -a claude-code`. Or copy the skill folder (plugins/mcp/servicegraph/skills/servicegraph in jeremylongshore/tons-of-skills-marketplace) into .claude/skills/servicegraph in your project. Claude Code loads it when a task matches its description.

How do I install Servicegraph in Codex?

Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill servicegraph -a codex`. Or copy the skill folder (plugins/mcp/servicegraph/skills/servicegraph in jeremylongshore/tons-of-skills-marketplace) into .agents/skills/servicegraph in your project. Codex loads it when a task matches its description.

Can I use Servicegraph in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill servicegraph -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/servicegraph, .gemini/skills/servicegraph, .github/skills/servicegraph and .opencode/skills/servicegraph in your project.

What does Servicegraph need to run?

Going by SKILL.md and its folder, Servicegraph needs credentials named SERVICEGRAPH_API_KEY. Our summary lists: A credential in SERVICEGRAPH_API_KEY. Its frontmatter pre-approves these tools: Bash(curl:*), mcp__servicegraph__list_datasets, mcp__servicegraph__describe_dataset, mcp__servicegraph__list_fields, mcp__servicegraph__list_field_values, mcp__servicegraph__check_filter, mcp__servicegraph__translate_intent, mcp__servicegraph__search_dataset, mcp__servicegraph__get_row, mcp__servicegraph__unlock_rows, mcp__servicegraph__get_credit_balance. Compatibility (from SKILL.md): Designed for Claude Code.

Does Servicegraph access the network?

SKILL.md names 4 domains. In commands or code: mcp.servicegraph.co and api.servicegraph.co; the agent is likely to contact these when it follows the instructions. As links in the text: servicegraph.co and github.com. This is read from the text; nothing was executed.

Is Servicegraph safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Servicegraph use?

Servicegraph is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Servicegraph use?

About 1.9k tokens (SKILL.md is roughly 7.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Servicegraph?

Skills that share tags, products or a category with Servicegraph: Interview (alirezarezvani/claude-skills, 28k stars), Igce Builder Cr (aiskillstore/marketplace, 433 stars), MCP Server Builder (anthropics/skills, 180k stars) and MCP Server Builder (shareAI-lab/learn-claude-code, 78k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
