2 Paid Tools & APIs Agents Actually Buy
Every tool with verified pricing that AI coding agents pay for via MCP or API key
Web Scraping & Search
Highest agent spend category| Tool | What | Free Tier | Paid Entry | Per-Unit | MCP Server |
|---|---|---|---|---|---|
| Apify | 1,000+ scraping actors | $5 credits | $29/mo | $0.20–0.30/CU | Yes mcp.apify.com |
| Firecrawl | Web scraping + extraction | 500 credits | $16/mo | ~$0.005/page | Yes |
| Browserbase | Headless browser infra | 1 hr free | $20/mo | $0.12/hr overage | Yes |
| Bright Data | Proxy + scraping | None | $500/mo | Enterprise | No |
| Tavily | AI-optimized search | 1K credits/mo | $30/mo | $0.008/credit | Yes |
| Exa | Neural search | 1K/mo | Volume tiers | ~$0.01/search | Yes |
| Serper.dev | Google SERP API | 2,500/mo | $50 50K credits | $0.30–1.00/1K | No |
| Brave Search API | Web search | $5 credits/mo | Metered | $5/1K queries | Yes community |
| SerpAPI | Multi-engine SERP | 100/mo | $75/mo | 5K searches | No |
| Jina AI Reader | URL → LLM text | Yes | Usage tiers | ~$0.01/page | No |
Compute & Sandboxes
Code execution| Tool | Free | Paid | Per-Unit | MCP |
|---|---|---|---|---|
| E2B | $100 credits | $150/mo | $0.000014/s/vCPU | Yes |
| Modal | None | Usage | $0.000014/core/s | No |
| Replicate | None | Usage | $/prediction varies | No |
Dev Platforms (with MCP)
Highest agent adoption| Tool | Free | Paid | MCP |
|---|---|---|---|
| GitHub | Public repos | $4–21/user/mo | Official |
| Linear | 250 issues | $8/user/mo | Official |
| Atlassian | 10 users | $7.75/user/mo | Official |
| Figma | 3 files | $12/user/mo | Official |
| Notion | Yes | $15/user/mo | Official |
| Supabase | Yes | $25/mo | Official |
| Vercel | Yes | $20/user/mo | Official |
| Cloudflare | Yes | $5/mo+ | Official |
| Stripe | Usage | 2.9% + 30¢ | Official |
Key pattern: Apify (1,000+ actors, official MCP at mcp.apify.com) is the largest paid scraping platform with agent integration.
Firecrawl, Tavily, and E2B form the "starter stack" for paid agent tooling. Dev platforms (GitHub, Linear, Figma)
dominate official MCP registry adoption — they're free-to-start but agents hit paid tiers fast in production.
3 Enterprise Marketplaces
Where agents buy migration tools, data connectors, and enterprise capabilities
Enterprise Marketplace Landscape
Agent-accessible platforms| Marketplace | What Agents Buy | Catalog | Pricing Model | Agent Access |
|---|---|---|---|---|
| Databricks Marketplace | ML models, notebooks, data connectors, migration tools | 1,000s | Usage-based / compute hours | API |
| Snowflake Marketplace | Data products, Cortex Agent tools, connectors | 2,000+ providers | Consumption credits | Cortex Agents |
| AWS Marketplace | MCP servers, AI solutions, SaaS tools | 100s AI-specific | Pay-go / subscription / BYOL | MCP Gateway |
| Azure Marketplace | AI agents, migration tools, MCP offerings | 10,000+ | Pay-go / EA | MCP Server |
| Salesforce AppExchange | Agentforce integrations, CRM agents | 7,000+ | Per-user subscription | AgentExchange |
| Atlassian Marketplace | Jira/Confluence MCP connectors, AI plugins | 5,000+ | Per-user / site-wide | MCP |
| ServiceNow Store | ITSM connectors, automation workflows | 1,000+ | Subscription | API |
| Composio | SaaS integrations (200K+ tool calls/mo) | 250+ apps | $29–$499/mo | MCP |
| Merge.dev | Unified API connectors for 3rd-party apps | 200+ | Usage-based | MCP |
Databricks + Snowflake are the data platform marketplaces where agents access migration tools programmatically.
AWS/Azure provide the infrastructure gateways. Salesforce AgentExchange is the first CRM-native agent marketplace.
All converging toward MCP as the standard agent integration layer.

Built-in Claude Code Skills (ship with every install)
Power user tools| Command | What It Does | Type |
|---|---|---|
| /batch | Parallel codebase changes across isolated git worktrees, one agent per unit | Orchestration |

Anthropic's #1 recommendation: "Give Claude a way to verify its work" — tests, screenshots, or expected outputs.
Priority order: CLAUDE.md → CLI tools (gh, aws) → MCP servers → hooks → skills → custom subagents.

◆ Discovery is the moat
Skills are text files on GitHub. The moat sits in who controls how agents find them: registries, gateways, ranking algorithms.
◆ Apify is the quiet giant
1,000+ actors, official MCP, $0.13–0.30/CU. Most comprehensive paid scraping platform with native agent integration via mcp.apify.com.
◆ Dev platforms win on lock-in
GitHub/Linear/Figma/Atlassian are free to start but agents hit paid tiers fast. They're in the official Anthropic MCP registry — built-in advantage.
