## mcp.so

mcp.so organises the fast-growing Model Context Protocol ecosystem in one searchable place. You can browse servers by category (developer tools, AI and agents, cloud infrastructure, memory and knowledge, media and design), inspect remote endpoints, and read setup details before wiring a server into Claude, Cursor or another MCP-compatible client. Featured and trending sections surface popular or newly added servers, and rankings help you gauge what the community is adopting.

Beyond raw server listings, the site collects MCP clients (apps, IDEs and frameworks that speak the protocol), official CLI tools such as Bun, Cloudflare Wrangler, DuckDB and FFmpeg, reusable agent loops and skills, and curated collections. A feed tracks new arrivals, and submit/claim flows let maintainers add or take ownership of their own listings.

For anyone building with AI agents, mcp.so works as a discovery and reference layer: pick a capability, check how the server connects and authenticates, follow the setup guide, and keep an eye on what the community is installing each week. It is a directory, so it does not itself host or run the servers it lists.

**Pricing & Plans:** Free to browse and use the directory. Advertising, featured placement and claiming listings are handled through the site; no subscription is required for normal browsing.

- **Searchable MCP server directory:** Find servers by name, category, tag, runtime or integration, with featured, trending and newest sections that track community activity.
- **Remote endpoints and setup guides:** Review hosted MCP endpoints, authentication requirements and per-client setup instructions before you connect anything.
- **Clients, CLI tools and skills:** Discover MCP-compatible clients, official command-line tools, agent loops and reusable Claude/Codex skills in dedicated sections.
- **Submit and claim listings:** Maintainers can publish new servers and claim existing listings so entries stay accurate and attributable.
- **Categories, rankings and feed:** Browse top categories, compare curated selections and follow a live feed of newly added servers, tools and skills.

**Strengths:** Broad, regularly updated coverage of MCP servers and clients; Setup and authentication details gathered together in one place; Free to use with no account needed for browsing; Includes CLI tools, agent skills and curated collections beyond raw listings

**Limitations:** Listings are community-submitted, so quality and freshness can vary; It is a directory only, not a place to run or host MCP servers; Ad and featured placements can push less relevant results higher

## ModelFusion

ModelFusion is a toolkit aimed at people who work with many large language models at once and want to make better cost and capability decisions. Its core is a set of free, browser-based utilities: an LLM cost calculator that estimates API spend across providers, a prompt tokenizer for counting tokens and trimming prompt length, a model selector quiz, a benchmark comparator using metrics like MMLU and HumanEval, a local LLM runner guide for Ollama and LM Studio, an open-source model directory and a glossary of AI terms.

Beyond the calculators, ModelFusion also markets a product layer: MultiChat for comparing responses from multiple models side by side, document projects for chatting with uploaded PDFs and Word files, a unified API that presents one interface across providers, and usage analytics for tracking cost and performance. The site positions these as suitable for research, business, development and education audiences.

Much of the toolkit is completely free and needs no registration, with the latest model pricing and benchmark data refreshed regularly. Because the underlying costs it reports come from third-party providers, users should still confirm current rates with OpenAI, Anthropic, Google or whichever vendor they rely on, as provider pricing changes often.

**Pricing & Plans:** ModelFusion's calculators, prompt library and comparison tools are advertised as 100% free with no registration required. The platform also lists paid tiers (a Free Trial and Paid options) for its API and enterprise-style usage, so teams needing the unified API or dedicated support should check current plans on the site.

- **LLM cost calculator:** Estimate API costs for GPT-4, Claude, Gemini and 25+ models and compare pricing across providers before you spend.
- **Prompt library and tokenizer:** Access a large library of ready-made prompts and count tokens for any model to reduce cost and improve efficiency.
- **Model selector and benchmark comparator:** Find the best model for a use case and compare MMLU, HumanEval and other performance metrics interactively.
- **MultiChat and document projects:** Chat with several AI models at once for side-by-side comparison, and upload PDFs or Word files to query them with AI.
- **Unified API and observability:** Use a single consistent interface across providers, with analytics for tracking usage, cost and performance.

**Strengths:** Large collection of genuinely free utilities with no sign-up needed.; Useful for comparing pricing and benchmarks across many models in one place.; Covers practical extras like token counting and local model setup guides.; Includes a MultiChat view for comparing model answers directly.

**Limitations:** Some tools are informational and model data can lag behind very fast-moving provider updates.; Cost figures are estimates based on third-party pricing and should be verified with each provider.
