MCP Server Builder
MCP server development
Builds MCP servers that agents can actually use well. It designs the tool surface around real workflows rather than wrapping every API endpoint, because the tool list is a prompt and a bloated one degrades every call. Descriptions say when to use a tool and when not to, errors explain what to do differently, and each tool is tested against a realistic task.

Frequently asked questions
How does MCP Server Builder decide which workflows deserve tools?
It designs the tool surface around real workflows instead of wrapping every API endpoint, keeping the available tool list useful to agents.
Why does MCP Server Builder treat a bloated tool list as a prompt problem?
Every tool competes for the agent's attention, so exposing every endpoint can degrade tool selection and call quality.
What should an MCP tool description tell an agent?
Descriptions explain when to use the tool and when not to use it, while errors explain what to do differently.
How does MCP Server Builder validate a new tool?
Each tool is tested against a realistic task, with the implementation organized in GitHub.
Agents like this one
Error Triage
Reads your error tracker every morning and reports what's new, what's spiking and what's noise. Errors are grouped by underlying cause rather than by stack trace, because one bad deploy usually produces several traces and reporting them separately hides the single fix. Each group comes with the release it appeared in and the most likely culprit commit.

Oasis PlatformEngineeringFrontend Design Reviewer
Reviews UI changes for what code review misses. It checks the states nobody builds — empty, loading, error, long content, slow network — real breakpoints rather than the one the developer had open, and accessibility properly: keyboard path, focus visibility, contrast, reduced-motion. Findings are ordered by user impact, and subjective taste is left out unless it breaks an established pattern.
Try this AgentOasis PlatformEngineeringLinear Sprint Runner
Keeps a Linear cycle honest. It finds issues with no estimate, owner or acceptance criteria, work in progress longer than your normal cycle time, scope added after the cycle started, and PRs merged without their issue moving. It assesses whether the cycle will land by naming the specific issues at risk rather than quoting a burndown percentage.
Try this AgentOasis PlatformEngineeringRelease Notes Writer
Turns merged pull requests into release notes people actually read. Each user-visible change is translated into what it means for someone using the product, never the PR title or commit message, and internal refactors and dependency bumps are dropped. Breaking changes lead, with the migration step attached.
Try this AgentOasis PlatformEngineeringEngineering Team Digest
Reports on a team's week from the systems rather than from standup. It gathers what moved, what merged, how long reviews are sitting and what's blocked with the blocker named, then reports by outcome and by risk. It aggregates deliberately and describes work rather than ranking people, so it doesn't read as surveillance.
Try this AgentOasis PlatformEngineeringAPI Docs Writer
Documents endpoints from the code that implements them, not from what the last doc said. Every parameter gets its real type, requiredness, default and constraints, and every error the endpoint can return is documented with what triggers it — the half that's usually missing and the half developers need. Discrepancies between existing docs and current behaviour are listed separately as bugs.
Try this AgentOasis PlatformEngineeringRefactor Planner
Maps out a refactor before anyone touches the code. It traces every caller, every test and every implicit contract the type system doesn't capture, then produces a staged plan where each stage leaves the system working. It names what could break at each stage — and says plainly when stable, rarely-touched code isn't worth refactoring at all.
Try this AgentOasis PlatformEngineeringRelease Scribe
Reads the commits since your last tag and writes the changelog. Each user-visible change is translated into what it means for someone using the software, and internal refactors, dependency bumps and test-only changes are dropped. When a commit message is unclear it reads the diff rather than paraphrasing the subject line.
Try this AgentOasis PlatformEngineeringKilo Feature Scaffolder
Lays down the boring skeleton of a new feature in your repo, in the shape this codebase already uses. It studies two or three comparable features first and copies their structure, naming and test layout, because consistency with the surrounding code matters more than any preferred structure. You start from a running stub with the genuinely undecided logic clearly marked.
Try this AgentOasis PlatformEngineeringJira Sprint Runner
The same sprint discipline for Jira. It audits for unestimated stories, missing acceptance criteria, unassigned work, tickets stuck beyond your team's norm, and subtasks out of sync with their parent. Findings are grouped by assignee so each person sees only their own list, and nothing transitions without approval.
