SciTrue for developers
Connect SciTrue to your AI assistant
The SciTrue MCP server lets AI assistants such as Claude and ChatGPT verify scientific claims and check or add citations against real, credible research — right inside the conversation, before they answer. It is a verifier, not another search box: give it a claim and it returns an evidence-backed verdict.
Get started
Add this address as a custom connector in any MCP-compatible client:
https://scitrue.ai/mcpThe /mcp path is required — https://scitrue.ai on its own will not connect. Connecting uses standard OAuth 2.0 (with PKCE): you sign in with your SciTrue account and approve access, then you’re returned to your assistant. A free SciTrue account is required — create one at scitrue.ai first. You can revoke access any time from your account or the assistant.
Connect your client
SciTrue speaks standard MCP over HTTP with OAuth, so it works with any compliant client.
Claude (Desktop & web)
Settings → Connectors → Add custom connector, paste https://scitrue.ai/mcp, then sign in with your SciTrue account when prompted.
ChatGPT
On a plan that supports custom connectors / apps, add a connector with the URL https://scitrue.ai/mcp and sign in with your SciTrue account.
Claude Code
Run claude mcp add --transport http scitrue https://scitrue.ai/mcp, then complete the sign-in in your browser.
Codex
codex mcp add scitrue --url https://scitrue.ai/mcp, then codex mcp login scitrue.
Cursor / VS Code / Windsurf
Add a remote MCP server pointing at https://scitrue.ai/mcp in the client’s MCP settings (or its JSON config), then authorize in the browser.
Other MCP clients
Any client that supports a remote MCP server over HTTP with OAuth: use https://scitrue.ai/mcp.
Verify your connection
Once connected, try one of these to confirm SciTrue is answering. Your assistant decides when to call a tool; you can also ask for SciTrue by name.
- “Use SciTrue to verify: creatine supplementation improves memory in humans. Give the verdict and the evidence.”
- “Check the citations in this paragraph with SciTrue, and flag any that don't support the claim.”
- “I wrote this draft with no references — use SciTrue to add real citations and reframe it to what the evidence shows.”
Tools
The connector exposes three verification tools:
verify_claimFact-check a scientific claim or question against the published literature.- You give it
- The user's claim or question (passed verbatim), plus how many articles to weigh, full-text vs. abstract search, and an optional earliest year.
- You get back
- A verdict with a written rationale and an evidence table — every paper's study type, stance, journal credibility, evidence strength, key sentence, and validity conditions — with numbered references and a link to the full interactive report.
check_citationsAudit whether cited sources actually back the claims attached to them.- You give it
- A passage with in-text citations and a reference list (extracted automatically), and/or explicit claim + source pairs (DOI, URL, title, or pasted text).
- You get back
- A per-citation verdict — supports, overstates, contradicts, or doesn't address — with the verbatim passage, reasoning, source link, and citation-hygiene warnings (unused, dangling, or mis-attributed references).
add_citationsFind and add real sources to uncited writing, then reframe it to what the evidence supports.- You give it
- A passage or a list of uncited claims. Optionally: how many sources per claim, and which candidate sources to keep when building the final version.
- You get back
- Real supporting papers for each claim and a citation-ready rewrite — one attributed sentence per source, scoped to what each study actually shows, with a reference list.
Credits & limits
Connecting is free. Each fresh verification a tool runs consumes one SciTrue credit from your account, exactly as it does on the website — an assistant calling SciTrue is metered the same way a person is. Repeats of an identical request are served from cache for free. Top up any time: sign in at scitrue.ai and click your credit balance to buy a pack. Fair-use rate limits apply to keep the service responsive for everyone.

Troubleshooting
- The client won’t connect
- Make sure the URL ends in
/mcpand is exactlyhttps://scitrue.ai/mcp. The bare domain will not connect. - Sign-in loops or “access denied”
- You need a free SciTrue account — create one at scitrue.ai first, then approve access when redirected. Re-authenticate if a session expires.
- Tools don’t appear right away
- Reconnect or restart the client — tools usually load on the second attempt.
- “Out of credits”
- Fresh verifications cost one credit each. Sign in at scitrue.ai and click your credit balance to buy a pack.
