How do I install Coalesce Transform?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Coalesce Transform need an API key?

The publisher lists these environment variables: COALESCE_ACCESS_TOKEN, COALESCE_PROFILE, COALESCE_BASE_URL, COALESCE_ORG_ID, COALESCE_REPO_PATH, COALESCE_CACHE_DIR, COALESCE_MCP_AUTO_CACHE_MAX_BYTES, COALESCE_MCP_INLINE_RESPONSES, COALESCE_MCP_LINEAGE_TTL_MS, COALESCE_MCP_MAX_REQUEST_BODY_BYTES, COALESCE_MCP_REQUEST_TIMEOUT_MS, COALESCE_MCP_DETAIL_FETCH_TIMEOUT_MS, COALESCE_MCP_NODE_TYPE_RANKING_TIMEOUT_MS, COALESCE_MCP_INVENTORY_CACHE_TTL_MS, COALESCE_MCP_NODE_INDEX_CACHE_TTL_MS, COALESCE_MCP_NODE_DETAIL_CACHE_TTL_MS, COALESCE_MCP_READ_ONLY, COALESCE_MCP_SKILLS_DIR, SNOWFLAKE_ACCOUNT, SNOWFLAKE_USERNAME, SNOWFLAKE_KEY_PAIR_KEY, SNOWFLAKE_PAT, SNOWFLAKE_KEY_PAIR_PASS, SNOWFLAKE_WAREHOUSE, SNOWFLAKE_ROLE.

What transport does Coalesce Transform use?

Coalesce Transform runs locally over stdio.

Credentials from the publisher

COALESCE_ACCESS_TOKEN — Bearer token from the Coalesce Deploy tab. Optional when `~/.coa/config` provides a `token`.
COALESCE_PROFILE — Selects which `~/.coa/config` profile to load. Defaults to default.
COALESCE_BASE_URL — Region-specific base URL. Defaults to https://app.coalescesoftware.io (US).
COALESCE_ORG_ID — Fallback org ID for cancel-run. Also readable from `orgID` in the active ~/.coa/config profile.
COALESCE_REPO_PATH — Local repo root for repo-backed tools and pipeline planning. Also readable from `repoPath` in the active ~/.coa/config profile.
COALESCE_CACHE_DIR — Base directory for the local data cache. When set, cache files are written here instead of the working directory. Also readable from `cacheDir` in the active ~/.coa/config profile.
COALESCE_MCP_AUTO_CACHE_MAX_BYTES — JSON size threshold before auto-caching to disk. Defaults to 32768.
COALESCE_MCP_INLINE_RESPONSES — Forces large responses inline as text instead of auto-caching them to disk and returning a `resource_link` (and suppresses per-field cache resource links). The server already auto-enables this for clients known not to support MCP resources (e.g. Snowflake Cortex), which otherwise render the link as unreadable "binary data" and retry in a loop. Set `true` to force it on for an unrecognised client, or `false` to disable auto-detection. Leave unset for Claude/Cursor to keep large payloads out of context. Defaults to false (auto-enabled for resource-less clients).
COALESCE_MCP_LINEAGE_TTL_MS — In-memory lineage cache TTL in milliseconds. Defaults to 1800000.
COALESCE_MCP_MAX_REQUEST_BODY_BYTES — Max outbound API request body size. Defaults to 524288.
COALESCE_MCP_REQUEST_TIMEOUT_MS — Default per-request timeout for Coalesce API calls. Raise on large workspaces where paginated reads exceed the default. Defaults to 60000.
COALESCE_MCP_DETAIL_FETCH_TIMEOUT_MS — Per-page timeout for detail=true paginated fetches of large node lists. Defaults to 180000.
COALESCE_MCP_NODE_TYPE_RANKING_TIMEOUT_MS — Deadline for the best-effort workspace-adoption node-type ranking lookup inside node creation. Advisory only — creation proceeds without a ranking suggestion if this trips. Defaults to 15000.
COALESCE_MCP_INVENTORY_CACHE_TTL_MS — In-memory TTL for the workspace node-type inventory. Set to `0` to disable. Defaults to 300000.
COALESCE_MCP_NODE_INDEX_CACHE_TTL_MS — In-memory TTL for the workspace node-index (id/name/type/location) cache used by SQL- and intent-ref resolution. Set to `0` to disable. Defaults to 300000.
COALESCE_MCP_NODE_DETAIL_CACHE_TTL_MS — In-memory TTL for the workspace node-detail (full body) cache used by review and predecessor lookups. Set to `0` to disable. Defaults to 300000.
COALESCE_MCP_READ_ONLY — When `true`, hides all write/mutation tools during registration. Only read, list, search, cache, analyze, review, diagnose, and plan tools are exposed. Defaults to false.
COALESCE_MCP_SKILLS_DIR — Directory for customizable AI skill resources. When set, reads context resources from this directory and seeds defaults on first run. Users can augment or override any skill.
SNOWFLAKE_ACCOUNT — Snowflake account identifier (e.g., `abc12345.us-east-1`). Required by the local `coa` CLI and `coa doctor`; not used by the MCP's REST run path. (required for run tools)
SNOWFLAKE_USERNAME — Snowflake account username (required for run tools)
SNOWFLAKE_KEY_PAIR_KEY — Path to PEM-encoded private key (required if SNOWFLAKE_PAT not set)
SNOWFLAKE_PAT — Snowflake Programmatic Access Token (alternative to key pair)
SNOWFLAKE_KEY_PAIR_PASS — Passphrase for encrypted keys
SNOWFLAKE_WAREHOUSE — Snowflake compute warehouse (required for run tools)
SNOWFLAKE_ROLE — Snowflake user role (required for run tools)
