Run this in a terminal to add the server to Claude Code.
What this does
mcp-context-server exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.

Frequently asked questions
How do I install mcp-context-server?
Run the Claude Code command in the install section to add mcp-context-server to Claude Code, or copy the ready-made config for your client from the install section on this page. Restart your client afterwards and the tools appear in your next conversation.
Which clients work with mcp-context-server?
This page carries setup and config for Claude Code, Claude Desktop, Cursor and VS Code. Any other MCP client that accepts a standard server config can connect to mcp-context-server as well.
Does mcp-context-server need an API key?
Yes. Before it can run, set these environment variables: LOG_LEVEL, STORAGE_BACKEND, MAX_IMAGE_SIZE_MB, MAX_TOTAL_SIZE_MB, DB_PATH, POOL_MAX_READERS, POOL_MAX_WRITERS, POOL_CONNECTION_TIMEOUT_S, POOL_IDLE_TIMEOUT_S, POOL_HEALTH_CHECK_INTERVAL_S, RETRY_MAX_RETRIES, RETRY_BASE_DELAY_S, RETRY_MAX_DELAY_S, RETRY_JITTER, RETRY_BACKOFF_FACTOR, SQLITE_FOREIGN_KEYS, SQLITE_JOURNAL_MODE, SQLITE_SYNCHRONOUS, SQLITE_TEMP_STORE, SQLITE_MMAP_SIZE, SQLITE_CACHE_SIZE, SQLITE_PAGE_SIZE, SQLITE_WAL_AUTOCHECKPOINT, SQLITE_BUSY_TIMEOUT_MS, SQLITE_WAL_CHECKPOINT, SHUTDOWN_TIMEOUT_S, SHUTDOWN_TIMEOUT_TEST_S, QUEUE_TIMEOUT_S, QUEUE_TIMEOUT_TEST_S, CIRCUIT_BREAKER_FAILURE_THRESHOLD, CIRCUIT_BREAKER_RECOVERY_TIMEOUT_S, CIRCUIT_BREAKER_HALF_OPEN_MAX_CALLS, POSTGRESQL_CONNECTION_STRING, POSTGRESQL_HOST, POSTGRESQL_PORT, POSTGRESQL_USER, POSTGRESQL_PASSWORD, POSTGRESQL_DATABASE, POSTGRESQL_POOL_MIN, POSTGRESQL_POOL_MAX, POSTGRESQL_POOL_TIMEOUT_S, POSTGRESQL_COMMAND_TIMEOUT_S, POSTGRESQL_MIGRATION_TIMEOUT_S, POSTGRESQL_MAX_INACTIVE_LIFETIME_S, POSTGRESQL_MAX_QUERIES, POSTGRESQL_TCP_KEEPALIVES_IDLE_S, POSTGRESQL_TCP_KEEPALIVES_INTERVAL_S, POSTGRESQL_TCP_KEEPALIVES_COUNT, POSTGRESQL_STATEMENT_CACHE_SIZE, POSTGRESQL_MAX_CACHED_STATEMENT_LIFETIME_S, POSTGRESQL_MAX_CACHEABLE_STATEMENT_SIZE, POSTGRESQL_SSL_MODE, POSTGRESQL_SCHEMA, ENABLE_SEMANTIC_SEARCH, ENABLE_EMBEDDING_GENERATION, OLLAMA_HOST, OLLAMA_AUTO_PULL, OLLAMA_PULL_TIMEOUT_S, EMBEDDING_OLLAMA_TRUNCATE, EMBEDDING_OLLAMA_NUM_CTX, EMBEDDING_MODEL, EMBEDDING_DIM, EMBEDDING_TIMEOUT_S, EMBEDDING_RETRY_MAX_ATTEMPTS, EMBEDDING_RETRY_BASE_DELAY_S, EMBEDDING_MAX_CONCURRENT, ENABLE_SUMMARY_GENERATION, SUMMARY_PROVIDER, SUMMARY_MODEL, SUMMARY_MAX_TOKENS, SUMMARY_TIMEOUT_S, SUMMARY_RETRY_MAX_ATTEMPTS, SUMMARY_RETRY_BASE_DELAY_S, SUMMARY_MAX_CONCURRENT, SUMMARY_PROMPT, SUMMARY_MIN_CONTENT_LENGTH, SUMMARY_OLLAMA_NUM_CTX, SUMMARY_OLLAMA_TRUNCATE, SUMMARY_OPENAI_REASONING_EFFORT, SUMMARY_ANTHROPIC_EFFORT, ANTHROPIC_API_KEY, ENABLE_FTS, FTS_LANGUAGE, FTS_RERANK_WINDOW_SIZE, FTS_RERANK_GAP_MERGE, ENABLE_HYBRID_SEARCH, HYBRID_RRF_K, HYBRID_RRF_OVERFETCH, HYBRID_FTS_OR_THRESHOLD, SEARCH_DEFAULT_SORT_BY, SEARCH_TRUNCATION_LENGTH, ENABLE_CHUNKING, CHUNK_SIZE, CHUNK_OVERLAP, CHUNK_AGGREGATION, CHUNK_DEDUP_OVERFETCH, ENABLE_RERANKING, RERANKING_PROVIDER, RERANKING_MODEL, RERANKING_MAX_LENGTH, RERANKING_OVERFETCH, RERANKING_CACHE_DIR, RERANKING_CHARS_PER_TOKEN, RERANKING_INTRA_OP_THREADS, RERANKING_CPU_MEM_ARENA, RERANKING_BATCH_SIZE, EMBEDDING_PROVIDER, OPENAI_API_KEY, OPENAI_API_BASE, OPENAI_ORGANIZATION, AZURE_OPENAI_API_KEY, AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_EMBEDDING_DEPLOYMENT_NAME, AZURE_OPENAI_API_VERSION, HUGGINGFACEHUB_API_TOKEN, VOYAGE_API_KEY, VOYAGE_TRUNCATION, VOYAGE_BATCH_SIZE, LANGSMITH_TRACING, LANGSMITH_API_KEY, LANGSMITH_PROJECT, LANGSMITH_ENDPOINT, METADATA_INDEXED_FIELDS, METADATA_INDEX_SYNC_MODE, MCP_TRANSPORT, FASTMCP_HOST, FASTMCP_PORT, FASTMCP_STATELESS_HTTP, DISABLED_TOOLS, MCP_AUTH_TOKEN, MCP_AUTH_CLIENT_ID, MCP_AUTH_PROVIDER, MCP_SERVER_INSTRUCTIONS.
