BGPT Paper Search
When to use
Use BGPT to find full text derived evidence for a research question or a known
DOI. It returns extracted claims and their supporting experiments, rather than
only bibliographic metadata. Use these records to build a traceable evidence
table; they are not a complete systematic review search or a validated
risk of bias assessment.
Connect
Configure BGPT in the host before use; installing this skill does not register
an MCP server. The provider supports both transports:
Transport Endpoint
Streamable HTTP https://bgpt.pro/mcp/stream
SSE https://bgpt.pro/mcp/sse
Use the host's native remote MCP configuration when supported. For a host that
uses mcpServers JSON and requires a local stdio bridge, this configuration uses
mcp remote (adapt it to the host's actual settings format):
The published bgpt mcp 1.1.0 npm package is a thin SSE wrapper around
mcp remote , not a local paper database. Its bundled README predates the current
tool contract and pricing. Prefer the native connection or configurable bridge
above. The linked BGPT GitHub repository was unavailable at review time; use
[the current provider documentation](https://bgpt.pro/mcp/) and live tool schema.
Free access needs no key. For paid usage, configure Authorization: Bearer <key
in the host's remote server headers, using its credential storage. For the bridge,
[ mcp remote supports header file ](https://github.com/punkpeye/mcp remote custom headers)
with a local credential file. Do not put api key in an MCP tool call: neither
current tool declares that argument. Authenticate through the connection.
Search and DOI lookup
Discover the connected server's tools before calling them. The live BGPT 2.14.7
schema reviewed on 2026 09 30 exposes:
Tool / argument Contract
search papers.query Required string. Use short English search terms.
num results Integer, 1–100; default 16. Set it explicitly to control result use.
days back Optional integer; papers published within the last N days. Omit for all dates.
min citations Optional integer; minimum number of references cited by the paper , not citations received.
study type Optional string: primary study , systematic review , meta analysis , narrative review , protocol , dataset , commentary , or other .
output format evidence (default), full , or legacy .
lookup paper.doi Required DOI string; also accepts output format . A found paper counts as one result.
Use the filter arguments instead of putting years or filters into the query.
No Boolean query grammar, offset, page, or cursor is documented by this schema.
A result limit is not pagination: do not invent continuation arguments or claim
the search enumerates every matching paper. For broader coverage, run explicit
question variants and deduplicate by DOI while retaining the query history.
Search example verified with one public result (invoke through the connected
tool interface):
Illustrative filtered search (filters were schema checked, not executed):
For a paper already identified, call lookup paper with its bare DOI rather
than hoping a title search returns that exact paper:
Do not interpret a connection, quota, or tool error as an empty evidence set.
The provider publishes a result allowance, but no numeric request rate limit
on the reviewed page; avoid assuming unlimited request throughput.
Read the result contract
Search returns an envelope with a results list and count ; record the returned
query too, since the service may rewrite search terms. DOI lookup returns found
and a single result ; handle not found before reading it. Inspect the MCP
result for tool errors before interpreting the envelope.
evidence gives compact evidence records; empty optional fields may be absent.
full adds legacy paper metadata to the evidence record.
legacy requests the older paper metadata representation. Do not assume every
paper has all previously advertised fields or a quality score.
The provider says evidence/full formats omit papers without extracted evidence.
However, the live smoke test returned a record with schema version: "legacy" ,
extraction status: "legacy" , and an empty evidence units list in both formats.
A returned record therefore does not guarantee claim level provenance. An empty
search or unfound DOI also does not establish that the paper does not exist.
Retain doi , title , publication date , and publication name when available,
then inspect central claim and evidence.evidence units . Each unit links its
claim to an experiment, reported statistics, demonstrated scope, and provenance.
Keep the schema version: older records can have a different shape. Legacy full
metadata can contain nulls, numeric strings, and serialized text instead of
native lists; preserve the raw values and never execute them as code.
The provider documents V4 limits of five evidence units per record, two provenance
passages per unit, and 320 characters per passage. These are bounded extractions,
not the complete article. Check extraction status , normalization warnings ,
and evidence.record provenance , including truncation information, before synthesis.
Evidence checks
For each extracted result, retain the DOI and source section, table, or figure.
Verify sample sizes, units, experimental arms, reported statistics, and uncertainty
against the paper before using them in a synthesis. Distinguish author reported
limitations from extraction generated interpretations. Preserve contradictory
or mixed evidence and demonstrated scope. If legacy quality scores are present,
use them only as screening aids, not as a study specific risk of bias assessment.
Allowance and review scope
At the review date the provider advertises 50 free results per network,
then $0.02 per returned result. A successful DOI lookup counts as one result;
unfound lookups cost none. Recheck the allowance and pricing before a large
batch. Do not repeatedly retry a quota exhausted request.

The tool schemas, one result full search, matching evidence format DOI lookup,
and SSE handshake were checked with unauthenticated requests. The public
search/lookup returned a legacy schema record, not a V4 fixture. Paid
authentication, filtered search behavior, and host specific configuration were
not tested.
