MCP 服务器

decixa-mcp

MCP server for Decixa that helps AI agents find and resolve APIs for tasks using natural language intents, with support for budget and latency filtering.

README

decixa-mcp

Find the right API for your AI agent. 30,000+ listings tracked. 5,500+ verified live as of April 2026.

MCP Server for Decixa — The decision layer for AI Agents.

v0.1.7: intent-driven update. New resolve / discover tools replace search_apis / browse_apis (kept as deprecated aliases). See CHANGELOG.md for migration guide.

Quickstart

# Claude Code
npx decixa-mcp

// Claude Desktop — claude_desktop_config.json
{
  "mcpServers": {
    "decixa": {
      "command": "npx",
      "args": ["-y", "decixa-mcp"]
    }
  }
}

// Cursor / Windsurf — .cursor/mcp.json or .windsurf/mcp.json
{
  "mcpServers": {

What you can do

resolve({ intent: "get real-time BTC price" })
→ Returns top recommendation + up to 2 alternatives, ranked by Phase 3 vector + scoring

resolve({ intent: "summarize Reddit posts", budget: 0.005 })
→ Filters by cost, returns trust_evidence and latency tier

discover({ intent: "transcribe audio", budget: 0.01, sort: "price_asc" })
→ Returns multiple x402-verified candidates so the agent can choose

Why Decixa

Unlike x402.direct, Decixa verifies x402 compliance by actually probing each endpoint — not just metadata analysis.

	Decixa	x402.direct
Listings tracked	30,000+	~4,000
x402 verification	HTTP 402 probe (real)	Metadata scoring
Capability classification	9 verb-based axes	—
Intent → API resolution	`/api/agent/resolve`	—
MCP server	`npx decixa-mcp`	—

Tools

`resolve` (recommended, replaces `search_apis`)

Find the best API for a task using natural language. Returns top recommendation + up to 2 alternatives. Decixa uses Phase 3 vector + scoring (vector 0.70 + latency 0.05 + price 0.05 + tiebreak 0.20). When no candidate clears the similarity threshold, returns recommendation_status='no_match' with up to 2 suggestions.

Parameter	Type	Description
`intent` (required)	string	What you want to do (e.g. `"summarize news articles"`)
`budget`	number	Max USDC per call (e.g. `0.01`)
`latency`	string	`low` / `medium` / `high`
`min_similarity`	number	Similarity threshold (0.2–0.9, default `0.5`). Out-of-range → 400

Response includes recommendation_status ("resolved" or "no_match").

`discover` (recommended, replaces `browse_apis`)

List APIs ranked by intent. Returns multiple candidates so the agent can choose. Verified-x402 only.

Parameter	Type	Description
`intent` (required)	string	Natural-language intent (mapped to server's `task` query param)
`tag`	string	Filter by capability tag (e.g. `"Market Data"`, `"Risk Score"`)
`budget`	number	Max USDC per call
`latency_tier`	string	`low` / `medium` / `high`
`execution_mode`	string	`sync` / `async`
`pricing_model`	string	`per_call` / `subscription` / `hybrid`
`min_similarity`	number	Similarity threshold (0.2–0.9, default `0.3`). Out-of-range → 400
`sort`	string	`relevance` (default) / `price_asc` / `price_desc` / `latency_asc` / `trust` / `calls` (deprecated)
`limit`	integer	Results per page (1–50, default 20)
`offset`	integer	Pagination offset

Response includes search_mode, min_similarity_applied, no_match_reason, top_candidates_below_threshold.

`search_apis` (deprecated alias for `resolve`)

DEPRECATED in v0.1.7. Will be removed in v1.0.0. Use resolve instead. Shares schema and handler with resolve.

`browse_apis` (deprecated alias for `discover`)

DEPRECATED in v0.1.7. Will be removed in v1.0.0. Use discover instead. Shares schema and handler with discover.

`get_api_detail`

Get full details for a specific API by ID.

Parameter	Type	Description
`api_id`	string	API ID from `resolve` or `discover`

Returns: endpoint URL, pricing, capability, tags, agent_compatibility, schema info, use_cases, trust_evidence (score / uptime_7d / p95_latency_ms / payment_req_parsed / last_checked / last_probed_at), provider, and verified_live flag. Prefer trust_evidence.score over legacy trust_score for new clients.

`get_index`

Entry point for agents new to Decixa. Returns platform overview, endpoints, and usage guidance.

No parameters required.

Migration from v0.1.6

Old	New	Notes
`search_apis({intent, capability, agent_ready})`	`resolve({intent, min_similarity?})`	Drop `capability` / `agent_ready`. They are silently ignored server-side (D-059).
`browse_apis({task, capability, agent_ready, sort})`	`discover({intent, sort})`	`task` → `intent`, drop `capability` / `agent_ready`. Default sort changed `trust` → `relevance`.
`list_capabilities({})`	(removed)	Capability filtering is no longer needed. Pass intent text + optional `tag` filter.

Strict MCP clients note: if your MCP client validates additionalProperties: false, it will reject capability / agent_ready arguments at the client side. Tolerant clients let them through, but Decixa silently ignores them server-side. Either way, remove them.
