Endpoint Security74
Transport & Reachability100
Schema Quality & AI Usability82
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 1785 tokens (~111/item across 16 items; 12 tools + 4 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management70
  • Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage88
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 56% of tool parameters carry a description.Partial
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
get_bundle ~176

Paid USDC on Base. Call when you need every card in a set at once (chips filings, major central banks, BRICS central banks), cheaper than buying them singly. Same JSON as the single cards. Ids, prices and contents follow (also in list_filers). Bundles: SEMIS ($0.06: AMD, MRVL, NVDA, AVGO, TSM, MU, AMAT, INTC, ASML); CENTRALBANKS ($0.08: BOE, FED, ECB, BOJ, RBA, BOC, SNB); BRICS ($0.08: BCB, IND, ZAF, CHN, RUS, IDN, ETH, EGY, IRN). Others return 404 (no charge).

Install

How do I install the FilingDelta MCP server?

FilingDelta is a hosted endpoint at https://filingdelta.xyz/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the FilingDelta MCP server?

FilingDelta is an MCP server listed in the public MCP registry as xyz.filingdelta/filingdelta. SEC filing changes, central-bank rate decisions, US macro and CPI cards. Pay per card via x402. This page covers its hosted endpoint (https://filingdelta.xyz/mcp).

Is the FilingDelta MCP server safe to use?

FilingDelta scores 81 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the FilingDelta MCP server expose?

FilingDelta exposes 12 tools: list_filers, search_coverage, whats_new, sample_delta, sample_policy, and 7 more. Their descriptions and schemas cost roughly 1,554 tokens of context every time the server is loaded.

Does the FilingDelta MCP server require authentication?

No. We connected to FilingDelta without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the FilingDelta MCP server still maintained?

FilingDelta is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
