  "markdown": "# Cala Plugin for Claude Code\n\nA Claude Code plugin that connects Claude to [Cala](https://cala.ai), the knowledge layer for AI agents.\n\nThis plugin is built and maintained by the Cala team. It is not an official\nAnthropic product, and inclusion in Anthropic's directories does not imply\npartnership, sponsorship, or endorsement by Anthropic.\n\n## What this does\n\nCala turns the open web into a verified, structured entity graph — typed data,\ndeterministic queries, and full source traceability. This plugin gives Claude direct access to Cala's knowledge base through\nMCP, so you can ask Claude things like \"find Spanish startups that raised\nbetween €10M and €50M\" and get back clean, sourced, typed answers instead of\na pile of links to parse yourself.\n\nCala supports two response shapes for the same input:\n\n- **Natural-language answers** — succinct, sourced markdown with citations.\n- **Structured answers** — typed, tabular JSON rows for programmatic use.\n\nBoth accept either a plain-language question or a Cala QL expression\n(dot-notation filters, e.g. `startups.location=Spain.funding>10M`).\n\n## Installation\n\nInstall via the Claude Code plugin marketplace:\n\n```\n/plugin install cala@claude-community\n```\n\nOr add this repository directly:\n\n```\nclaude plugin marketplace add cala-ai/cala-claude-plugin\n```\n\n## Authentication\n\nThis plugin connects to Cala's hosted MCP server at `https://api.cala.ai/mcp/`.\n\nOn first use, Claude Code will prompt you to sign in to\nyour Cala account and authorize access. No API keys or credentials are stored\nin this repository or in your local configuration.\n\n## Available tools\n\n| Tool | Description |\n|---|---|\n| `knowledge_search` | Get a succinct, token-optimized natural-language answer with sources, explainability, and matching entities. Accepts a natural-language question or a Cala QL expression. |\n| `knowledge_query` | Get verified knowledge as structured, typed JSON rows plus matching entities. Accepts a Cala QL expression or a natural-language question. |\n| `entity_search` | Find entities by name with fuzzy matching. |\n| `entity_introspection` | Get the field schema for an entity by its UUID — available properties, relationships, and numerical observations. |\n| `entity_retrieval` | Retrieve full details for a known entity by its UUID. |\n\nFull API reference: [docs.cala.ai/api-reference](https://docs.cala.ai/api-reference)\n\n## Pairing with the Cala agent skill\n\nFor the best experience, install the Cala skill alongside this plugin so\nClaude knows how to use these tools well out of the box:\n\n```\nnpx skills add cala-ai/cala-skill\n```\n\nSee [docs.cala.ai/integrations/agent-skill](https://docs.cala.ai/integrations/agent-skill) for details.\n\n## Using this MCP server with other clients\n\nThis plugin packages Cala's server for Claude Code specifically. Cala's MCP\nserver also works directly with Cursor, VS Code, Claude Desktop, Codex, and\nany other MCP-compatible client — see\n[docs.cala.ai/integrations/mcp](https://docs.cala.ai/integrations/mcp) for\nper-client setup instructions.\n\n## Support\n\n- Docs: [docs.cala.ai](https://docs.cala.ai)\n- Support: [heyeli@cala.ai](mailto:heyeli@cala.ai)\n\n## License\n\nMIT",
