Open-source, evidence-provenance-first scientific literature MCP server
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"literature-evidence-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# Literature Evidence MCP An open-source **scientific literature and evidence provenance** MCP server. > **Important:** v0.3 is a **bibliographic/traceability and evidence-audit MVP**, NOT an automated peer reviewer, meta-analysis engine, PRISMA-compliant review engine, validated quality score, or scientific truth oracle. It never labels a paper scientifically proven solely from an abstract or citation. ## Features implemented in v0.3 | MCP tool | Status / guarantee | | --- | --- | | `search_literature` | OpenAlex, Europe PMC, Crossref concurrent metadata search, DOI deduplication, provider error reporting. Search is non-exhaustive. | | `get_paper` | Crossref metadata, relations, publisher links. | | `verify_citation` | Exact normalized DOI/title metadata match, NOT content verification. | | `check_retraction` | Crossref `update-to` checks, including Retraction Watch updates where available. Absence is inconclusive. | | `read_fulltext` | Europe PMC/PMC XML for supplied PMCID; records section/paragraph-span IDs, offsets, XML and paragraph SHA-256, and truncation. No PDF page claims. | | `verify_source_quote` | Fetches Europe PMC JATS XML and returns direct matching paragraph IDs, section, and hashes; no scientific validity verdict. | | `verify_claim` | Deterministic literal text presence only. Does not prove scientific claim. | | `assess_methodology` | Transparent keyword/phrase screening; NOT risk-of-bias evaluation. | | `audit_methodology` | Outcome-specific source-anchored HUMAN-SUPPLIED annotation validation. Flags untraceable/contradictory evidence; never infers formal RoB2/ROBINS-I judgments. | | `audit_pmc_methodology` | Fetches Europe PMC full-text JATS XML by PMCID and independently anchors human annotations to exact paragraphs with source SHA-256; handles truncated sources explicitly. | | `check_statistical_reporting` | Screens user-supplied p values, sample sizes and CI range inconsistencies; does NOT recompute analyses. | | `compare_studies` | Metada…
