Coresignal

Retrieves comprehensive B2B company data (financials, industry classification, employee counts, locations, technologies) through MCP protocol endpoints that query Coresignal's proprietary database. Implements standardized MCP resource handlers that normalize company data into structured JSON responses, enabling LLMs to access real-time company intelligence without direct API calls.

Searches Coresignal's employee database to retrieve professional profiles including work history, job titles, skills, and employment timeline. Implements MCP tool handlers that accept search parameters (name, company, location, skills) and return paginated employee records with verified employment data, enabling AI agents to identify talent or validate professional backgrounds.

Aggregates job postings from multiple sources through Coresignal's job board database, exposing them via MCP resources with filtering by company, location, job title, and industry. Parses job descriptions into structured fields (requirements, responsibilities, salary ranges where available) and enables LLMs to analyze hiring trends, skill demand, and competitive intelligence across job markets.

Implements MCP (Model Context Protocol) server that handles authentication, request routing, and response serialization for Coresignal API calls. Manages API credentials securely through environment variables or configuration files, abstracts HTTP client complexity, and provides standardized MCP resource and tool definitions that Claude and other LLM clients can discover and invoke automatically.

Supports complex company queries combining multiple filters (industry, employee count range, revenue range, location, technology stack, growth rate) through MCP tool parameters. Translates filter combinations into Coresignal API query parameters and returns ranked results, enabling LLMs to perform sophisticated company discovery without requiring developers to build custom query logic.

Processes arrays of company names, domains, or employee records through Coresignal API in batch mode, enriching each record with verified B2B data (company size, industry, technologies, employee profiles). Implements batching logic that groups requests efficiently and handles partial failures gracefully, enabling LLM workflows to enrich large contact lists without timeout or rate-limit issues.

Tracks job posting changes (new postings, closed positions, title changes) for specified companies through periodic polling of Coresignal's job database. Exposes hiring activity as MCP resources that LLMs can query to detect hiring trends, expansion into new markets, or leadership changes, enabling sales and intelligence workflows to react to hiring signals in real-time.
