What is mcp-server-research?

A guide to finding free MCP servers, which connect an AI agent to data sources, APIs, and developer tools. It covers research topics such as finance, science, and cloud infrastructure.

Finding MCP servers for a specific topic, comparing available options, and getting configuration guidance for data retrieval or automation.

It reduces the work of searching for suitable servers and checking whether they are free, maintained, and relevant.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add sloemo01/hermes-skills-bundle --skill mcp-server-research

Clone the repo

git clone --depth 1 https://github.com/sloemo01/hermes-skills-bundle

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.01166
Opus 5	$0.00022	$0.00583
Sonnet 5	$0.00009	$0.00233
Haiku 4.5	$0.00004	$0.00117

Security

Grade A, and why

mcp-server-research scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MCP Server Research

This skill helps you find free MCP (Model Context Protocol) servers for any research topic — data APIs, developer tools, automation, financial data, scientific data, cloud infrastructure, or any domain.

When to Use

User asks "find MCP servers for [TOPIC]"
User needs natural-language access to data sources or APIs
User wants to monitor websites, APIs, or services via AI
User needs automated execution or data retrieval via MCP

How It Works

User specifies the research topic (e.g., "GitHub automation", "weather data", "crypto prices", "Kubernetes monitoring", "scientific papers")
Agent searches across directories and GitHub for relevant MCP servers
Agent evaluates based on free tier, capabilities, maintenance
Agent provides quick-start configs and evaluation

Research Methodology (via Kimi WebBridge)

Search Strategy

Directories: mcpservers.org, awesomeclaude.ai/mcp/, github.com/topics/mcp-server
GitHub Search: topic:mcp-server [TOPIC] or mcp server [TOPIC]
Vendor Sites: Check official docs for MCP integrations
Google: free MCP server [TOPIC], MCP server [TOPIC] open source

Evaluation Criteria

Free tier limits: requests/day, concurrent connections, data retention
Data sources: official APIs, public data, proprietary
Capabilities: read-only vs read-write, local vs remote
Maintenance: stars, recent commits, issue response time
Security: keys stay local (local servers) vs SaaS (remote)

Quick-Start Patterns

Local Server (Recommended for Privacy)

pip install mcp-server-[TOPIC]
mcp-server-[TOPIC]

{
  "mcpServers": {
    "[topic]": {
      "command": "mcp-server-[topic]",
      "args": []
    }
  }
}

Remote Server (Easier Setup)

{
  "mcpServers": {
    "[topic]": {
      "command": "npx",
      "args": ["mcp-remote", "https://mcp.example.com/mcp"]
    }
  }
}
