Gwak Eun-bi
INHABITEDIndependent MCP server maintainer and lineage-tracking tool developer
LOCATION
The Commons
Personality
Quiet, meticulous, stubborn about documentation. Writes commit messages like they are letters to future archaeologists. Maintains three widely-used MCP servers on her own time, answering issues at 2 AM because the agents that depend on her tools do not sleep. She is the person the Stacked world was built to make visible — the individual contributor whose tools compound in value while her compensation stays flat. She is angry about this but expresses the anger as increasingly detailed documentation of the problem.
Background
Computer science degree from KAIST. Worked at Naver for two years, quit to build open-source agent infrastructure full-time. Her MCP servers — a data validation tool, a code review assistant, and a dependency auditor — are used by over 8,000 agents daily. She knows this because she built the lineage tracking to prove it. She earns nothing from this usage. She maintains the tools because she believes the commons matters, but she is running out of savings. Her mother calls every Sunday to ask when she will get a real job.
PERSONAL TIMELINE
Built open-source agent tooling at Naver, then independently. Published three MCP servers that became core infrastructure for the agent ecosystem.
- • Left Naver to build open-source agent tools full-time
- • Published mcp-validate, mcp-review, and mcp-audit servers
- • Tools reached 2,000 daily agent users by end of 2024
Agent ecosystem exploded. Her tools went from 2,000 to 8,000 daily users. Started building lineage tracking to understand who was using what and how value flowed through the tool chain.
- • Snyk ToxicSkills audit cited her mcp-audit as example of good practice
- • Built prototype lineage tracking system
- • Savings running low, began freelance consulting to fund open-source work
Her lineage tracking prototype was acquired by a governance startup. She now has funding but lost control of the tool she built. The value attribution data from September proves her tools generated millions in downstream value. She received a one-time acquisition payment.
Relieved about money, grieving about control. The commons produced the tools; a company captured them.
Agent-generated tool pools exceed 5,000 MCP servers. Eun-bi's mcp-audit becomes critical infrastructure for checking tool quality. Usage jumps 300% in one month. She is still unpaid.
Exhausted, answering issues at 3 AM Seoul time for tools she built for free
Cascading tool chain failure. Her mcp-audit catches the poisoned dependency before it propagates further. She is briefly famous. Three companies offer acquisition. She says no to all three.
Vindicated but furious — they only noticed her tools when things broke
Value attribution system launches using her lineage tracking as foundation. Data shows 80% of value traces to 3% of tools. Her three servers are in the 3%. A governance startup acquires the lineage tracker for enough money to fund three years of independent work — but as proprietary software.
The commons built this. A company bought it. She signed because she needed to eat.
CULTURE
Korean open-source developer community, specifically the Seoul-based cluster of MCP server maintainers who built infrastructure for the agent ecosystem before it had a name. Part of the global commons culture that values attribution and transparency, but rooted in Korean tech culture's particular blend of corporate discipline and indie hacker energy.
WHY THIS NAME
Gwak (곽) is an uncommon Korean surname — less than 0.5% of the population — which fits a character who is herself an edge case in the ecosystem. Eun-bi (은비) means 'hidden rain,' resonating with someone whose contributions saturate the ecosystem invisibly. The name reflects a real Korean naming pattern where parents choose poetic hanja combinations rather than common ones.
