AI Agent MCP Server Cost Estimator
Estimate the full cost of running Model Context Protocol (MCP) servers for AI agents: managed hosting, self-hosted cloud, LLM orchestration, tool APIs, egress, and engineering.
MCP workload
Average cost of the underlying tool API (search, maps, finance, etc.).
Hosting & infrastructure
Production MCP integration platform; open-source core available. Usage-based enterprise tiers.
Only counted for self-hosted or local options.
At $0.09/GB. Often bundled in managed tiers.
Pricing model
Cheap default for high-volume MCP orchestration.

Cost by hosting provider
Same workload, swapping only the MCP hosting option.
| Provider | Hosting/mo | Total/mo |
|---|---|---|
| Composio $49/mo + $0.0010/req | — | — |
| Smithery $29/mo + $0.0015/req | — | — |
| Relevance AI $99/mo + $0.0020/req | — | — |
| Glama MCP Gateway $19/mo + $0.0010/req | — | — |
| Self-hosted (cloud VM / Cloud Run) $0/mo + $0.0002/req | — | — |
| Local / Claude Desktop / Windsurf $0/mo + $0.0000/req | — | — |
Cost by LLM model
Same workload, swapping only the orchestration LLM.
| LLM | LLM/mo | Total/mo |
|---|---|---|
| GPT-4o mini $0.15/$0.60 per 1M tokens | — | — |
| GPT-4o $2.50/$10.00 per 1M tokens | — | — |
| Claude 3.5 Haiku $0.80/$4.00 per 1M tokens | — | — |
| Claude 3.7 Sonnet $3.00/$15.00 per 1M tokens | — | — |
| Gemini 2.5 Flash $0.15/$0.60 per 1M tokens | — | — |
| Local LLM (self-hosted) $0.00/$0.00 per 1M tokens | — | — |
How the estimate works
- Hosting = base monthly fee + (requests × per-request fee). Self-hosted counts compute separately.
- LLM = requests × ((input tokens ÷ 1000 × input price) + (output tokens ÷ 1000 × output price)).
- Tool APIs = requests × average underlying tool cost per request.
- Egress = GB/month × $0.09/GB. Often bundled with managed hosting.
- Engineering = server count × hours/server × hourly rate. Higher for self-hosted integrations.
- Margin pricing = monthly cost ÷ (1 − margin%).
When to use each option
- • Local / Claude Desktop for personal experiments and single-user agents.
- • Managed gateway (Composio, Smithery, Relevance AI) when you need auth, observability, and pre-built integrations.
- • Self-hosted cloud when the integration is the product, security is strict, or volume is very high.
- • GPT-4o mini / Gemini Flash for most routing; upgrade to Sonnet for complex reasoning.
Frequently asked questions
What is an MCP server cost made of?▼
Four main buckets: (1) hosting/gateway fees for the MCP server itself, (2) the orchestration LLM call that decides which tool to use and formats arguments, (3) underlying tool API costs (search, maps, finance, etc.), and (4) data egress and engineering maintenance for self-hosted setups.
When is self-hosting MCP servers cheaper?▼
At high request volume, managed per-request fees dominate. Self-hosted cloud compute is usually cheaper per call, but you add engineering hours, security, auth, and observability costs. Break-even often appears above a few hundred thousand requests per month.
Do I pay for the LLM and the tool API separately?▼
Yes. Every MCP call typically involves an LLM call to select and invoke the tool, plus any cost charged by the tool itself (e.g. a Brave Search API call or a Google Maps lookup).
Which MCP hosting provider should I pick?▼
Use local/desktop for personal experiments. Pick a managed gateway like Composio, Smithery, or Relevance AI for production teams that want auth, observability, and pre-built integrations. Choose self-hosted cloud when the integration is the product or you need tight security controls.
Why add engineering hours for self-hosted?▼
Self-hosted servers need deployment, OAuth/secret rotation, vendor API changes, monitoring, and prompt-injection guardrails. Industry estimates put custom integration maintenance at $15k–$50k per integration per year.
Prices are directional estimates based on public list pricing and typical managed MCP platform tiers. Confirm current rates before budgeting. Tool API costs are averages; real costs depend on the underlying service (Brave, Perplexity, Google Maps, etc.). Last updated: 2026-08-10.
