Servicegraph

nostrband/servicegraph

Connects Claude to ServiceGraph's business datasets: agencies, product directories, newsletters, and business directories, all filterable by metrics like domain rating, traffic, size, and location. The generic `servicegraph` skill discovers schemas and searches across any dataset, while specialized skills like `find-marketing-agency` or `find-web-developer` auto-pin filters for US professional services firms. Free browsing and brief cards, credits unlock full contact details and enrichment. Runs on streamable HTTP at mcp.servicegraph.co. You'd reach for this when prospecting launch venues, building outreach lists, or researching service providers without manually scraping directories. Requires an API key from servicegraph.co with 2,000 free credits on signup.

Public tool metadata for what this MCP can expose to an agent.

list_tagsReturns the catalog of fields, kinds, operators, and (optionally) value lists that the filter DSL accepts. Call this once per session to discover what you can query. Use include_values=true to expand the value list for every field; pass q to filter by name/description substring.2 params

Returns the catalog of fields, kinds, operators, and (optionally) value lists that the filter DSL accepts. Call this once per session to discover what you can query. Use include_values=true to expand the value list for every field; pass q to filter by name/description substring.

Parameters* required

include_valuesboolean

Expand the legal value list for every field (slower).

qstring

Substring filter on field name or description.

check_filterValidates a filter DSL string without executing it. Returns {valid, normalized, tables_used, param_count} on success or {valid:false, error:{code,message,position}} on parse error. Cheap; use it before search_firms / explore_firms to sanity-check generated filters.1 params

Parameters* required

filterstring

DSL filter string, e.g. "industry:legal state:CA"

explore_firmsCounts and per-facet breakdowns for the catalog under a filter. Use this BEFORE search_firms to size the query and choose narrowing facets.
