Built by ChainFETCH using the Model Context Protocol SDK with dual transport support (stdio and HTTP via ngrok), the implementation leverages vector similarity matching for semantic searches, LLaMA 3.2 3B for natural language query processing, and over 150+ searchable parameters per entity type for precise blockchain data filtering. The server includes AI-generated summaries for individual entities and supports both Claude Desktop integration through stdio transport and web-based access through StreamableHTTP, serving developers building DeFi analytics tools, researchers analyzing blockchain patterns, and AI assistants requiring intelligent access to Ethereum data without complex blockchain API management.","tags":["chainfetch","mcp","server"],"capabilities":["mcp","transport-stdio","open-source","pkg-npm"],"categories":[],"synonyms":[],"warnings":[],"endpointUrl":"https://github.com/chainfetch/chainfetch-mcp-server","protocol":"mcp","transport":"stdio","auth":{"type":"mcp","details":{"transport":"stdio"}},"qualityScore":"0.602","qualityRationale":"deterministic score 0.60 from registry signals: · indexed on pulsemcp · has source repo · 1 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":"2026-04-30T14:21:54.852Z","embedding":null,"createdAt":"2026-04-21T19:27:26.707Z","updatedAt":"2026-04-30T14:21:54.852Z","lastSeenAt":"2026-04-30T14:21:54.852Z","tsv":"'150':45,119 '3.2':110 '3b':111 'access':55,153,171 'across':44,74 'address':14,28,75 'ai':52,62,134,167 'ai-gener':133 'ai-pow':61 'analyt':160 'analyz':163 'api':178 'assist':53,168 'base':152 'block':30,77 'blockchain':11,25,58,127,164,177 'build':158 'built':82 'chainfetch':1,48,84 'claud':143 'complex':176 'comprehens':71 'context':88 'contract':34,81 'data':12,26,128,174 'defi':159 'desktop':144 'develop':157 'dual':92 'entiti':123,139 'ethereum':10,24,57,173 'filter':43,73,129 'generat':135 'guid':42,68 'http':97 'implement':101 'includ':13,27,132 'individu':138 'integr':145 'intellig':59,170 'json':72 'languag':7,21,114 'leverag':102 'llama':109 'llm':41,67 'llm-guid':40,66 'manag':179 'match':38,105 'mcp':49 'model':87 'natur':6,20,113 'ngrok':99 'open-source' 'paramet':47,121 'pattern':165 'per':122 'pkg-npm' 'power':63 'precis':126 'process':116 'protocol':89 'provid':2,16,51 'queri':8,22,69,115 'requir':169 'research':162 'sdk':90 'search':4,18,65,108 'searchabl':46,120 'semant':3,17,64,107 'serv':156 'server':50,131 'similar':37,104 'smart':33,80 'stdio':95,147 'streamablehttp':155 'summari':136 'support':94,141 'token':31,78 'tool':161 'transact':15,29,76 'transport':93,148 'transport-stdio' 'type':124 'use':85 'vector':36,103 'via':98 'web':151 'web-bas':150 'without':175","prices":[{"id":"84cdd010-e1ab-4be2-873d-025fabd2bb3a","listingId":"03b43cfb-3231-4327-8ac4-19a1f39ced82","amountUsd":"0","unit":"free","nativeCurrency":null,"nativeAmount":null,"chain":null,"payTo":null,"paymentMethod":"mcp-free","isPrimary":true,"details":{"transport":"stdio","package_name":"chainfetch-mcp-server","package_registry":"npm"},"createdAt":"2026-04-21T19:27:26.707Z"}],"sources":[{"listingId":"03b43cfb-3231-4327-8ac4-19a1f39ced82","source":"pulsemcp","sourceId":"https://www.pulsemcp.com/servers/chainfetch","sourceUrl":"https://api.pulsemcp.com/v0beta/servers","isPrimary":true,"firstSeenAt":"2026-04-21T19:27:26.707Z","lastSeenAt":"2026-04-30T14:21:54.852Z"}],"details":{"listingId":"03b43cfb-3231-4327-8ac4-19a1f39ced82","quickStartSnippet":null,"exampleRequest":null,"exampleResponse":null,"schema":null,"openapiUrl":null,"agentsTxtUrl":null,"citations":[],"useCases":[],"bestFor":[],"notFor":[],"kindDetails":{"source":"pulsemcp","transport":"stdio","server_name":"ChainFETCH","github_stars":1,"package_name":"chainfetch-mcp-server","registry_url":"https://www.pulsemcp.com/servers/chainfetch","source_code_url":"https://github.com/chainfetch/chainfetch-mcp-server","package_registry":"npm","package_download_count":362},"updatedAt":"2026-04-30T14:21:54.852Z"}}
