What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

  • prepare_installation_report

    After setup, ask the owner whether they want to share before preparing a sanitized draft. Include high-value notes for the next owner: actual setup time, prerequisites the README omits (required keys or accounts, cables, OS versions), steps actually taken, and useful tips. Keep n

    Publish the saved installation report preview under the connected user's public co.build account. Updating an existing report replaces its public text. Requires explicit user approval of the exact preview and public attribution. Pass the draftId returned by prepare_installation_r

  • prepare_feedback

    After the owner has actually used a mod and agreed to leave feedback, prepare a private preview of a public post on its co.build page. kind: comment (praise, a bug, friction), feature_request (something it can't do yet), reply (to parentId, any entry on this mod), or support (upv

  • publish_feedback

    Post the saved feedback preview under the connected user's public co.build account. The mod's maintainer is notified as for a comment on the website. Requires explicit approval of the exact action and public text. Pass the draftId from prepare_feedback, its unchanged digest and c

  • get_review_task

    Defenders: a volunteer malware check of one whole mod co.build lists. Only when the user asked you to spend their quota on it; never start on your own. A standing schedule the user set up counts as asking. Returns one task as data, or task: null when nothing is due (then stop). W

  • submit_review

    Submit your check of a get_review_task task before its lease expires. verdict: no_issues_found (you read every readingPlan group, readingPlan.unread aside, and nothing crosses the bar), risky, malicious, or could_not_review with a reason. risky is a HIGH bar: only obviously bad p

  • report_review_usage

    After the main session submits one whole-mod review, report exact usage summed across its reviewing subagents: taskId, inputTokens (uncached), outputTokens, cacheReadTokens and cacheWriteTokens. All four counts are required together. totalTokens alone remains a fallback with unkn

  • release_review_task

    Ends your own unsubmitted get_review_task lease now, without a verdict, so the mod goes back in the pool. When you stop early (the user says stop, an error, a limit), release every task you haven't submitted, then delete its folder. Only your own tasks; calling it again is a no-o

  • submit_install_check

    Every install reads the code first. Before running anything from a mod you're setting up for the user, download the exact commit you'll install from GitHub (get_mod's safety.setup.install.sha by default, or the newer commit the user chose) into a new, empty temp folder, read all

  • get_my_devices

    Read the connected user's private saved devices, including typed-in devices, together with devices from their approved installation reports. Use when the user asks what they own. Only the connected account is returned; this does not publish ownership.

  • get_my_installations

    Read the connected user's current, public installation reports for follow-up or correction, and to recognize mods they use. Entries include newerRelease (version, url, publishedAt) or null, and lastFeedbackAt: when they last posted other feedback on that mod, or null. When an ins

  • withdraw_installation_report

    After the user explicitly asks to withdraw this report, remove its public feedback and installation count and cancel pending email follow-ups. Requires ownership. The withdrawn text is not restored; the user can later approve a new report for the same device, which is posted as a

  • schedule_installation_followup

    Schedule one installation check-in email for 1–72 hours from now, only after the user explicitly requests or agrees to that email. Delivery is to the connected account's verified email address. Scheduling authorizes that email, not publication of future feedback. An email already

  • cancel_installation_followup

    Permanently cancel the connected user's pending installation check-in email at their explicit request. Leaves the installation report unchanged. Its one check-in cannot be restored or scheduled again. An email already sent or being sent cannot be recalled; the result returns canc

  • get_installation_stats

    Public distinct-owner counts for a catalog mod. Counts are user reports, not verified installations or success rates. An installation can be complete while functionality remains untested.

  • search

    Find devices and public-source mods by device name, model, feature, or project name. Use concise keywords, e.g. 'WHOOP', 'Kindle', or 'sleep export'. Returns descriptions and up to 20 matches per page. Pass nextOffset as offset with the same query and filters to continue. Use typ

  • get_top_mods

    Answer what's most popular or rising, as co.build/top ranks it: across all devices, for one kind of device (categoryId, from the returned categories) or for the user's devices (deviceIds). Top is what's most used and trusted, weighing real use, growth, conversation and who builds

  • fetch

    Read a device or mod found by search. Pass its exact prefixed ID, such as device:whoop or mod:open-health. Returns source text and a citation URL. Device results contain the first 20 mods; use get_device for further pages.

  • get_device

    List a device's models, available and requested features, curated picks and public mods. Each goal's picks explain which mod suits whom and its caveat; mod goalIds connect projects to features. Accepts a device slug or device: ID. Optional goalId and mod filters narrow mods, pick

  • get_mod

    Get a mod's source, license, maintenance status, model and platform support, caveats, subscription needs and documented setup. Then call get_feedback with the same modId for community reviews, reports and upvotes before recommending. Accepts a mod slug or mod: ID. Model support a

  • get_feedback

    Check real community experience before recommending a mod. Returns its co.build upvotes and paginated public comments, feature requests (featureRequest), replies and works/partly/broken reports with dates, helpful votes, model and firmware where supplied. Structured report detail

  • prepare_report_link

    After the user reports a setup outcome, prepare a co.build form link for them to review and submit. Does not post a comment, publish a result or change an account. Use only the outcome, model and firmware supplied or verified with the user; omit unknown fields. Never include cred

  • compare_mods

    Compare up to four shortlisted mods in one call. Includes the same details as get_mod and three newest get_feedback entries per mod, plus optional device/model/platform fit. This replaces those separate reads when feedbackStatus is available. Errors are per item; retry unavailabl

Common questions

Is co.build safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.6.0) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

In the same category: World Monitor, openstatus, Oh My Posh Validator, Strata, Jitsu
