read_pubmed_paper
Retrieve PubMed paper content by providing alternative methods when direct access is unavailable, including Sci-Hub for pre-2023 publications or Semantic Scholar as a fallback.
Instructions

2. read_semantic_paper(id) - last resort
Args:
paper_id: PMID (unused).
save_path: Unused.
Returns:
Error message with alternatives.

Implementation Reference
- paper_find_mcp/server.py:283-298 (handler)The primary handler function decorated with @mcp.tool(), which registers it as an MCP tool and executes the logic by calling the generic _read helper for the 'pubmed' platform.@mcp.tool() async def read_pubmed_paper(paper_id: str, save_path: Optional[str] = None) -> str: """PubMed does NOT support direct paper reading. INSTEAD (try in order): 1. read_scihub_paper(doi) - if published before 2023 2. read_semantic_paper(id) - last resort Args: paper_id: PMID (unused). save_path: Unused. Returns: Error message with alternatives. """ return await _read('pubmed', paper_id, save_path)
- paper_find_mcp/server.py:137-157 (helper)Generic helper function _read that all read_*_paper tools call. It retrieves the platform searcher from SEARCHERS dict and calls its read_paper method, handling NotImplementedError by returning the error message.async def _read( searcher_name: str, paper_id: str, save_path: Optional[str] = None ) -> str: """通用阅读函数""" if save_path is None: save_path = get_download_path() searcher = SEARCHERS.get(searcher_name) if not searcher: return f"Error: Unknown searcher {searcher_name}" try: return searcher.read_paper(paper_id, save_path) except NotImplementedError as e: return str(e) except Exception as e: logger.error(f"Read failed for {searcher_name}: {e}") return f"Error reading paper: {str(e)}"
- The platform-specific read_paper implementation in PubMedSearcher class. Since PubMed does not host full-text papers, it returns an instructional message directing users to alternatives like DOI or PMC.def read_paper(self, paper_id: str, save_path: str) -> str: """尝试读取 PubMed 论文(不支持) Returns: str: 说明信息 """ return ( "PubMed papers cannot be read directly through this tool. " "Only metadata and abstracts are available through PubMed's API. " "Please use the paper's DOI to access the full text, " "or check if the paper is available on PubMed Central (PMC)." )
- paper_find_mcp/server.py:283-298 (registration)The @mcp.tool() decorator registers this function as an MCP tool named 'read_pubmed_paper', with input schema inferred from the function signature.@mcp.tool() async def read_pubmed_paper(paper_id: str, save_path: Optional[str] = None) -> str: """PubMed does NOT support direct paper reading.
