What you can do
  • Submit a question to Oathlayer for independent verification
  • Receive a trust tag: approved, threshold not met, various perspectives apply, too complex, or clarity needed
  • Get a permanent doc number that anyone can look up for free to confirm the record is genuine
When to use it
Useful when an assistant's answers need an outside trust signal or an auditable record, for example when drafting content or research where readers may want to confirm a claim was checked. Not a substitute for your own judgment, since it reports results rather than deciding right or wrong.
Requirements
A remote MCP endpoint at mcp.oathlayer.com over streamable HTTP; no package, environment variables or headers are declared. Usage is metered: a free trial of 5 verifications with no card, then paid credits (one per check, valid 12 months, from $9 for 500).
Before you install
Each verification consumes a credit, so usage costs money after the free trial. Questions submitted are sent to a third-party service, so avoid confidential or sensitive content. The result is a trust signal, not a correctness guarantee, and it does not judge right or wrong for you.

Installation

In SourceWeft

  1. Open Oathlayer in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.oathlayer%2Foathlayer/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Oathlayer

Trust is everything. Oathlayer is an independent check on AI answers. It checks each answer against independent sources, gives it a clear verification tag, and records it with a permanent doc number that anyone can look up for free.

Oathlayer reports what happened. It does not judge right or wrong for you. It works on any topic and with any AI model.

Ways to use it

  • Ask Oathlayer at oathlayer.com/ask: ask a question or paste up to 5 legal citations and get a clear table of results. No programming needed.
  • API for your own apps: oathlayer.com/docs
  • AI agents (MCP): connect to https://mcp.oathlayer.com and use the verify_output tool.

Free trial

5 free verifications. No card needed. Start at oathlayer.com/signup.

The Five Pillars of Trust

TagMeaning
Verification Successful - Oath ApprovedPassed the verification threshold.
Verification Threshold Not MetA strong answer that did not pass the threshold. Double check it.
Various Perspectives ApplyA valid answer exists, but reasonable people may see it differently.
Complex Question - Threshold ReservedNeeds specialist knowledge. An answer is given, but the threshold is reserved.
Clarity Needed to ContinueThe question is too unclear to check. Ask again with more detail.

Citation Checks

Paste a case citation and Oathlayer checks it against official court sources. Each citation gets a short tag:

Short tagMeaning
ConfirmedFound on official court or government sources.
UnofficialFound, but only on unofficial sites. Check it before relying on it.
MismatchedPart of the citation does not match the real case. The correct version is shown.
Not foundCannot be found in available sources.

If trusted sources report that a case has been overruled, the result also shows Reported overruled.

This checks the citation only, not whether the case supports your argument.

Every answer is documented

Every answer gets a unique doc number. Anyone can check that it is genuine at oathlayer.com/verify, free and with no account.

Pricing

Pay for what you use. One credit per check. Credits are valid for 12 months. No subscriptions.

From $9 for 500 verifications. See oathlayer.com.
