The implementation exposes a single tool called 'query_docs' that forwards user queries to a Langflow API endpoint, which processes document-based questions using a Mistral model. The server runs on stdio transport for seamless integration with Claude Desktop, making it particularly valuable for workflows that require document-based information retrieval without leaving the conversation interface.","tags":["langflow","document"],"capabilities":["mcp","transport-stdio","open-source"],"categories":[],"synonyms":[],"warnings":[],"endpointUrl":"https://github.com/gongrzhe/langflow-doc-qa-server","protocol":"mcp","transport":"stdio","auth":{"type":"mcp","details":{"transport":"stdio"}},"qualityScore":"0.580","qualityRationale":"deterministic score 0.58 from registry signals: · indexed on pulsemcp · has source repo · 15 github stars · registry-generated description present","verified":false,"liveness":"unknown","lastLivenessCheck":null,"agentReviews":{"count":0,"score_avg":null,"cost_usd_avg":null,"success_rate":null,"latency_p50_ms":null,"narrative_summary":null,"summary_updated_at":null},"enrichmentModel":"deterministic:mcp:v1","enrichmentVersion":1,"enrichedAt":"2026-04-28T08:22:16.818Z","embedding":null,"createdAt":"2026-04-28T08:22:16.818Z","updatedAt":"2026-04-28T08:22:16.818Z","lastSeenAt":"2026-04-28T08:22:16.818Z","tsv":"'ai':65 'answer':15,35,75 'api':93 'assist':66 'base':46,99,127 'call':83 'claud':5,25,115 'connect':4,24,64 'context':60 'convers':133 'desktop':6,26,116 'doc':20,40,54,85 'document':2,12,32,45,72,98,126 'document-bas':44,97,125 'endpoint':94 'expos':79 'forward':87 'implement':78 'inform':128 'integr':113 'interfac':134 'langflow':1,10,30,53,70,92 'langflow-doc-qa-serv':52 'langflow-pow':9,29,69 'leav':131 'make':117 'mcp' 'mistral':50,103 'model':51,59,104 'open-source' 'particular':119 'power':11,31,71 'proce':23 'process':43,96 'protocol':61 'qa':3,55 'queri':19,39,84,89 'question':14,34,47,74,100 'question-answ':13,33,73 'requir':124 'retriev':129 'run':107 'seamless':112 'server':56,62,106 'singl':81 'stdio':109 'system':16,36,76 'tool':21,41,82 'transport':110 'transport-stdio' 'use':48,101 'user':88 'valuabl':120 'without':130 'workflow':122","prices":[{"id":"22b67a15-66bd-423a-999f-b922670fbcaa","listingId":"44748364-e542-44f3-8cd7-89a8d56e0b00","amountUsd":"0","unit":"free","nativeCurrency":null,"nativeAmount":null,"chain":null,"payTo":null,"paymentMethod":"mcp-free","isPrimary":true,"details":{"transport":"stdio"},"createdAt":"2026-04-28T08:22:16.818Z"}],"sources":[{"listingId":"44748364-e542-44f3-8cd7-89a8d56e0b00","source":"pulsemcp","sourceId":"https://www.pulsemcp.com/servers/gongrzhe-langflow-document-qa","sourceUrl":"https://api.pulsemcp.com/v0beta/servers","isPrimary":true,"firstSeenAt":"2026-04-28T08:22:16.818Z","lastSeenAt":"2026-04-28T08:22:16.818Z"}],"details":{"listingId":"44748364-e542-44f3-8cd7-89a8d56e0b00","quickStartSnippet":null,"exampleRequest":null,"exampleResponse":null,"schema":null,"openapiUrl":null,"agentsTxtUrl":null,"citations":[],"useCases":[],"bestFor":[],"notFor":[],"kindDetails":{"source":"pulsemcp","transport":"stdio","server_name":"Langflow Document QA","github_stars":15,"registry_url":"https://www.pulsemcp.com/servers/gongrzhe-langflow-document-qa","source_code_url":"https://github.com/gongrzhe/langflow-doc-qa-server"},"updatedAt":"2026-04-28T08:22:16.818Z"}}
