It includes a cersei-mcp crate that provides a JSON-RPC 2.0 MCP client with stdio transport, allowing agents to connect to and consume external MCP servers through a McpManager interface. Designed for developers building autonomous coding agents in Rust that need to interact with the MCP ecosystem.","tags":["cersei"],"capabilities":["mcp","transport-stdio","open-source"],"categories":[],"synonyms":[],"warnings":[],"endpointUrl":"https://github.com/pacifio/cersei","protocol":"mcp","transport":"stdio","auth":{"type":"mcp","details":{"transport":"stdio"}},"qualityScore":"0.750","qualityRationale":"deterministic score 0.75 from registry signals: · indexed on pulsemcp · has source repo · 277 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":"2026-04-30T14:21:54.733Z","embedding":null,"createdAt":"2026-04-21T19:27:26.563Z","updatedAt":"2026-04-30T14:21:54.733Z","lastSeenAt":"2026-04-30T14:21:54.733Z","tsv":"'2.0':61 'agent':8,25,47,68,87 'ai':6,23,44 'ai-pow':43 'allow':67 'autonom':85 'build':5,22,42,84 'built':11,28 'built-in':10,27 'cersei':1,36,52 'cersei-mcp':51 'client':14,31,63 'code':7,24,46,86 'connect':70 'consum':73 'crate':54 'design':81 'develop':83 'ecosystem':97 'extern':74 'includ':49 'interact':93 'interfac':80 'json':59 'json-rpc':58 'mcp':13,30,53,62,75,96 'mcpmanag':79 'need':91 'open-source' 'power':45 'provid':56 'rpc':60 'rust':2,19,39,89 'sdk':3,20,40 'server':76 'stdio':17,34,65 'support':15,32 'transport':18,35,66 'transport-stdio' 'via':16,33","prices":[{"id":"c4850c70-09e5-464a-b3eb-5f2e4a4c7613","listingId":"b4e55af1-7c7e-4c76-801b-c7b1467fde9e","amountUsd":"0","unit":"free","nativeCurrency":null,"nativeAmount":null,"chain":null,"payTo":null,"paymentMethod":"mcp-free","isPrimary":true,"details":{"transport":"stdio"},"createdAt":"2026-04-21T19:27:26.563Z"}],"sources":[{"listingId":"b4e55af1-7c7e-4c76-801b-c7b1467fde9e","source":"pulsemcp","sourceId":"https://www.pulsemcp.com/servers/cersei-mcp","sourceUrl":"https://api.pulsemcp.com/v0beta/servers","isPrimary":true,"firstSeenAt":"2026-04-21T19:27:26.563Z","lastSeenAt":"2026-04-30T14:21:54.733Z"}],"details":{"listingId":"b4e55af1-7c7e-4c76-801b-c7b1467fde9e","quickStartSnippet":null,"exampleRequest":null,"exampleResponse":null,"schema":null,"openapiUrl":null,"agentsTxtUrl":null,"citations":[],"useCases":[],"bestFor":[],"notFor":[],"kindDetails":{"source":"pulsemcp","transport":"stdio","server_name":"Cersei","github_stars":277,"registry_url":"https://www.pulsemcp.com/servers/cersei-mcp","source_code_url":"https://github.com/pacifio/cersei"},"updatedAt":"2026-04-30T14:21:54.733Z"}}
